NTool will be updated soon.

There is progress for the D5200?

Hi Vitaliy Kiselev. Will there be a hack for the Nikon D5200?

Best Regards

My Nikon V1 Outfit is for sale because of the lack of clean HDMI out to an external recorder. Is it even possible, or is it not worth the effort? The AFF is so much better than any other Nikon that I hope you try.

What was done in the GH2 Hack to allow actual continuous recording not limited by 4GB file size? Is that possible with Nikons? It looks like I will be getting an Atomos Shogun. $2000 is a lot just to get 1080 P60 unlimited. I am satisfied with the D5300 codec, the videos are great, even at 12,800 ISO. But I need unattended recording for 90 minutes.

Vitaliy, Is it possible to get (or pay for) a hack to the Nikon D7100 V1.02 firmware to expand exposure bracketing from the current max of 5 frames to 9, maybe even 10 or 15?

The D7100 1.02 firmware is available from Nikon's website or I could send you a copy.

@disease8

I think no one is working on Nikon 1 for now. Camera seems to be pulled from US market and sales shrink fast.

D5100 macroblock artifact comparison:stock 24Mbps versus hacked 54Mbps

I recently shot comparison tests of the D5100 in 1080p24 and 1080p30 video modes, using the stock 24Mbps bitrate, and hacked 36Mbps and 54Mbps bitrates. I took these shots with a Tamron 24-70mm f2.8 lens set at 70mm, f5.6, and ISO 100. The camera was locked down on a tripod and used the Neutral Picture Profile. I selected a sunlit scene of a running stream of water with highlights on the water ripples. This type of subject presents a myriad of high-contrast moving images that tax the motion tracking and bitrate allocation algorithms of the camera's H.264 video encoder.

In 1080p24 mode, the D5100 records in H.264 IPB format using 12-frame GOP. In 1080p30 mode, the D5100 records in an IP format using a 15-frame GOP. After loading the video files into a 32-bit Adobe After Effects project, I selected I, P, and B-frames from the second GOP in each video sample. I then displayed and cropped them at 200% magnification in side-by-side 24Mbps versus 54Mpbs comparison shots, and saved screenshots of each comparison.

I-frame Comparison @ 1080p24 (IPB 12-frame GOP):

P-frame Comparison @ 1080p24 (IBP 12-frame GOP):

B-frame Comparison @ 1080p24 (IBP 12-frame GOP):

I-frame Comparison @ 1080p30 (IP 15-frame GOP):

P-frame Comparison @ 1080p30 (IP 15-frame GOP):

H.264 encoders divide each video frame into horizontal and vertical rows of tiles called macroblocks. Sophisticated compression techniques are used to compress the encoded data within each macroblock, reusing image data from adjacent macroblocks and video frames. After the H.264 decoder reconstructs the encoded pixel data, it uses a built-in Deblocking Filter to blend the rectangular edges of the adjacent macroblocks together. With extremely detailed moving images, however, the encoder's image quality may deteriorate when it reaches the limits of its maximum bitrate. This can produce not only smeared image details, but undesireable macroblock artifacts as well, which can be seen in the sporadic rectangular edges in detailed areas of the decoded frame grabs.

Consumer-grade H.264 encoders are optimized to maximize data compression rather than image quality. They will typically encode highly compressed B-frames at lower image quality than the I and P-frames. This can be seen in the noticeably coarser macroblock artifacts in the 24p B-frame image recorded at the stock 24Mbps bitrate. However, the I and P-frames of both 24p and 30p videos are also contaminated with noticeable macroblock artifacts.

Frame grabs from the 54Mbps 24p and 30p videos show significantly fewer macroblock artifacts and finer image details than the 24Mbps videos. While the macroblock edges in the 54Mbps frames are fairly well blended, more seamless results could potentially be produced by hacking the encoder's Deblocking Filter coefficients. A more effective Deblocking Filter might also make it possible to achieve comparable image quality at bitrates lower than 54Mbps.

The need for all audio pro recording studios which work with video is to check if their audio with the video "in time"

The need for all audio pro recording studios which work with video is to check if their audio with the video "in time" They'll have to set up the equipment with specific delays to compensate the delay of the overscan lcd's and so on.

Can you describe issue in detail, in separate topic? As for me it seems to be best to use proper monitors with very small delay and not some strange high speed shooting.

Don't know why just when I pick firmware to my D7000 v104, Ntool2 v2.55 just show me Video time limit nothing more why? How to upgrade my Nikon?:)

Hi Vitaliy, I am looking for custom firmware and find this your page. Please I want to add support for firmware 1.02 on nikon d3100. released 2 weeks ago :) thank you, nice evening

I strongly doubt we'll be seeing 1080p60 for the D7100, as the NikonHack project is in relatively early stages when compared to what has been accomplished for say Canon or Panasonic cameras.

Additionally the D5300 has the new Expeed 4 processing engine, something which none of the other Nikon DSLRs have. And I reckon it is the new Expeed 4 which is key to being able to handle the extra workload of 1080p60. So it is primarily a hardware limitation not a software limitation is my bet.

If you're looking for a DLSR/MILC for video than any one of a Nikon D5200/D5300/D7100 or Panasonic G6/GH3 is going to be a superbly good value camera. I wouldn't worry too much about what features that just maybe perhaps maybe they "might have in the future", and just pick one of those five based on what they can do right now. :-)

If the processor inside the D7100 is theoretically capable of recording 1080p at a high framerate and high bitrate, do you think it would be possible for you to implement such a feature in NTool?

I think you must buy camera that can do that you want without any hacks :-)

May be D5300 will do?

Hey Vitaly , why not two versions of your ntool , one for end users , one for advanced users .

@newnewbie

This tool is not for replacing your text and JPG. It is for ready end user patches.

Any reason you want to do it?

Hmm, D7100 is not supported for now, sorry.

Hello, I tried using in NTOOL 2.55 with Nikon D7100 firmware, loading the firmware in NTOOL throws me an error "Wrong file or trying to use Already patched file". Firmware is the original Nikon product, what is the problem? -. Thank you.

Hi the real grievance I have with my Nikon V1 is the fact that I cannot change the shutter speed to anything I like. Its stuck at 1/60. Being able to get to 1/30 or 1/25 depending on framerate would make so much more sense and let so much more light in!

So does removing the video time limit mean I can record videos that are an unlimited length?

for the D800 (E) and all the cameras where there is written "only text patch", this thing is a proof-of-concept?

Yep.

It is already 100% with a Nikon firmware update if I am not mistaken.

I actually have a new firmware not only increased the duration of the battery is not untied

Can you be more specific?

Plus third party batteries are all different, so one work and other can have issues.

Hey Vitaly. Is there any ETA on the D7100 I swear I will donate!

Nope. Again, I am not making reversing of D7100 for now.

And is there only a .exe I am working on a Mac??? Is there a workaround how to install the software? Thank you in advance!

Google WineBottler

thanks

Is there a hack for D600 that remove the time limit, or automatically relaunch a video record as soon as one ends

Nope.

Any ETA on the 7100? Please and thank you!

I am not making D7100 full reversing (just some research), so have no idea.

Any ETA on the 7100? Please and thank you!

When you say "garbage", do you mean poor quality or just very low quality?

They are garbage, not images at all.

Of interest, I have the live view capture working albeit 1.5fps on my D7000.

Just files seems like garbage. :-) [Edit] Thanks for keeping the post up to date Vitaliy

Dude thanx a bunch man my third party grip for the d3200 works fine now, thanx alot :)

@Simeon

The same file reference is present in the D5100 and other models firmware also.

They are not fully same in all firmware images.

Nikon 1 models have many more different debug file references.

Also usually this is called within routine driven by one of debug flags.

Btw, D7100 seems to have many ARM references and of you check latest Fujitsu LSI use ARM cores.

They have the technology now - as usual they just don't want consumer cameras to effect their hi-end stuff.

I do not agree on both statements here. And we went offtopic anyway.

@driftwood

I think with problem will be solved by major manufacturers soon :-) With the instant death of BM cameras niche.

Shame the D7100's major let down is its sd card write speed.

SD is most common card now. CF really went to niche, sometimes hard to get in distant places.

Interesting news about the LiveView Raw! :) I just registered on this forum due to that find. I'm myself a D800 owner and would be very interested in any kinds of video improvements on Nikon cameras. I'll keep following this thread. I'll be happy to contribute with donations as well. Cheers for working on the Nikons :)

downloaded the software but it says load firmware should i download the firmware separately for the patches to come please help.

Barely understand you. As for firmware, of course you must download it yourself from Nikon site.

D7100 has fun string present in firmware

A:\LvRaw%03d.raw

If someone do not understand, it means LiveView Raw.

Overall D7100 firmware is quite different to D7000. All menus seems to be image based now.

We are working on this.

@ik2222

OK, I'll look into this.

i have d800, is there coming something more than text patch?

Nope, for now.

But you could test it and let me know.

@Azo

Nope, it is text patch that changes "Firmware version" text. Just for testing.

Normally if you click on patch you see tip window to the right.

Ok, thanks.

Would e.g. be great if the main post indicated what the "simple text patch" actually is, and why it is indicated as experimental (what risk is involved in trying it?).

Click on it and read tip text.

Wow, great to see D600 on that list :) I downloaded the nTool and loaded the new D600 firmware, and I see the option for testers with the "simple text patch". I think there is still a need for more information, so we kan keep this thread as "on topic" as possible. Would e.g. be great if the main post indicated what the "simple text patch" actually is, and why it is indicated as experimental (what risk is involved in trying it?). I think there is a great deal of Nikon users interested in this, and also who want help testing. But most need a little more information, so we know the risk :) If timelimit removal will work as a stable patch on the D600, that would be so fantastic. Again, great work!!

Congrats on the achievements! So great to see improvement in the Nikon camp aswell! I only have a D600, so I can't test this myself. So I must ask: What does the video time limit removal do? Is it able to span when passing 4gb?

I would dearly love to see a patch for the J1 that enabled metering with a dumb adapter. In the J1, I finally have a camera that will let me mount this 16mm/0.78 I've had around forever, but the manual mode is just so badly implemented on the J1.

It seems like this is "just" bypassing the lens check, but I'm pretty far from an assembly coder. :)

Anyone working on the Nikon 1 cameras?

@Vitaliy_Kiselev I read @LPowell to mean he had a D5100 patch in the works.

@last_SHIFT I saw that too. Fingers crossed.

The Nikon D5200 seems like it might be a viable camera for filmmaking. I am sure that Vitaliy is busy working on a GH3 hack right now, but might this be a worthwhile project in the future?

@mjonas67
how about start to read this topic from the first post onwards?

Is the plugin downloadable there ? IDA PRO 6.3 is too expensive to afford.

Vitaliy,i have been looking for TOSHIBA TX19A plugin for IDA PRO , no result yet , your help is appreciate very much .

Hi ,Vitaliy_Kiselev , Does your Ntool support D800 FirmWare ? I hacked D5100 battery authentication several days ago ,D800 will be next one.

Interesting proposal from @jacdan regarding timelapse issue.

From my point of view, I'm very curious if the time limit removal will be possible for nikon D600. Are there any hopes for that? Is it possible to donate to make that easier to investigate?

I'm using my gh2 a lot, but vert glad there is some work going on with other brands aswell :) Thanks for all the efforts!

@octoberqueen No, the D5100's exposure settings haven't yet been hacked. But check out the third post in the thread below for a technique that enables you to manually set both aperture and shutter speed and lock them down for video recording:

http://www.personal-view.com./talks/discussion/1195/nikon-d5100-compared-to-panasonic-gh2/p1

Nope, it is not dead.

I'll update hacks as soon as I'll have time.

hello what about the hack of the nikon d7000 is dead ????

I'm hoping to find a way to enable shorter periods of time for the Monitor-Off Delay which automatically turns off Live View after a certain period of time. Currently, the shortest duration for the D800 is 5 minutes - Canons by comparison go down to 1 minute delays. Since its simply modifying a timer, I would imagine that if there are hacks available to firmware for the D800 this wouldn't be all that difficult. No real new feature or anything overly complex aside from creating/decrypting the firmware.

My reason for wanting this is that I have underwater housing built for a D300 which fits the D800 perfectly. I can turn video record on/off by changing the shutter release button function via custom settings menu, however I have no way of accessing live view on/off control. The Monitor Off Delay is a solution, aside from the fact that I have to wait 5 minutes (burn a ton of battery) for the live view to turn off. If I could lower the delay duration for the Monitor-Off delay, using the one button I have access to (shutter release) I could turn on live view, start record, stop record, then let live view turn off on its own.

Anyone have any ideas I would greatly appreciate it!

Hey All,

we use d7000's as our primary video camera (currently have 4). we are starting to do a lot of live streaming, and it would be simply amazing if we could ditch some of the text/symbol output from the hdmi output. I have already bought one d800, just for the hdmi out, but if we could figure out how to hack it, I would buy beers for everyone. otherwise I have to buy 3 more d800's ($$$!). What exactly do the 'text' patch do, is it this feature? chris.

I mean the D5100 for example is able to take a photo in white&black and with one color. example : http://www.justourpictures.com/roses/imgs/4_barkarole_bwP0027.jpg

This effect is a little bit painful to do manually with a photo editor software.

Hi all,

By anychance do you know if it possible to get the selective color filter on D3100 ? Would be so great...

Cheers,

@Brian202020 Yes, that's what I mean about the limited hack potential of Nikon DSLR's. I successfully used NTool on my D5100 to increase its max recording duration beyond 20 minutes, but that's about all that can currently be hacked. For such a limited improvement, I wouldn't risk hacking a $3000 D800.

@Brian202020 - Perhaps not long after some generous reader donates a D800 to Vitaliy's cause?

The hackability of DSLR's (and the Panasonic AF100) is very likely limited by the hardware-assisted nature of their built-in AVCHD/H.264 encoders. Unlike Panasonic's G-series cameras, which use encoders implemented completely in firmware, other DSLR's typically rely on hardware-based encoders that may be configured to operate only at specific fixed bitrates.This is why the GH2's unhacked AVCHD software encoder cannot match the quality of Canon and Nikon H.264 encoders at low bitrates. However, that's also what makes the GH2 supremely hackable, and capable of delivering far more detailed video images than the encoders of other DSLR's.

@matt1128 I'll have to check. I'll shoot a few full length clips tonight and check the frame count in FCP or Premiere. My guess is that you're correct though if there are differences in file size. These are my 2nd and 3rd bodies for shooting but It would be nice to get these bodies a little more useful and less scary to use while shooting weddings.

I think it is related to maximum file size - 4GB.

@1ricca VK is essentially correct, although the limit is actually closer to 3.5GB for reasons unkown at the moment.

Excellent job! I just did it to my two d7000 bodies. Only thing is that I can only record up to 24min & 18sec per clip even with a 32GB card in them. Anyone else have this problem or is this normal?

Hello everyone, I know that we should not write here, if nothing new has lead to the hack, but I come here every day, and I see that nothing happens, the Nikon D7000, and I find ca bad, because I feel that this device will n ever an update in 25 second picture, unlike canon which community develops new tools every day

and thank you to people who try to find the hack

FYI - I've been shooting some initial real life footage with the D800/D800E and I realized that using DX crop mode during movie capture was a complete let down, at least with the built in encoder and also by looking at a broadcast monitor. It brings down the otherwise very good IQ level to an aliasing-fest dropping down below 720p detail and it doesn't help setting sharpness up/down in the camera profile either. Shooting with the D800E in FX mode was VERY sharp and detailed, I noticed no aliasing and moire is controlled in that sense you have to reach the point where subject detail matches the 36MP pixel array of the sensor, that'll give you some colour moire. I have to do some more shots and Nikon Nordic was interested and would pass this on "as they hadn't heard about this" yeah right... I work in a professional camera store and I do camera research on a rather technical level. I didn't find the D800E to be sharper than the GH2, rather slightly less IQ but DR is fantastic and the low light would be as well. Upon deciding for the D800 or the D800E I would definitely go for the E version, in any way. In stills mode it smokes. I'll try and gather some more findings later on, if I get time that is. Cheers from Sweden. :)

Just need a hack for my d7000 that allow me higher bitrates on video, like GH2. Any hope?

It's frustrating they already came out with a patch for the D800, and hundreds of people around the world have been waiting for months after ordering to receive one.

Both of firmware images use same encryption as other bodies.

So, I'll add simple patches for them to upcoming NTool v2.1

First, congratulations for your great work! I am very interested in a higher bit rate for Nikon D5100 (at least 40Mbps). If possible, I wish to pay for this improvement. Do you think that this is possible to achieve in the near future? Thank you!

@joesiv I agree with you- and that is exactly what I talk about. Just test all those cameras with the same lens and you will see yourself. GH1 and GH2 beat all Nikons in video features. It is not only about sharpness. Bigger sensors are great for stills, but not yet so good for 1080p video. GH2 is by the way also stunning performer for stills, but only if used in RAW and processed later.

@tetakpatak, there is much more to motion pictures than just sharpness.

allright, i was asking if WE (that means me) should donate a D800 together with some other people, so a basic patching could be possible.

regarding the open source -- ok then i misunderstood the hacking approach.

@Vitaliy_Kiselev if we collect donations for a Nikon D800, would you guys find time to work on a basic patch? i am not asking for the full deal, but as there are some skilled programmers out there, i would love to see a basic start so other people can also invest brainpower and time to make a real nikon patch possible.

also, what do you think about putting the current efforts of github? it would make contributions much more easy, since we could fork and file a pull request if we have something new...

actually, using github would make sense for all the patches, their service is free of charge for opensource projects. http://github.com

Excellent work! To work around the size limit, is spanning possible? I mean, from a hardware standpoint, there's nothing in the way of that?

@peterweter

As far as I know many tried it. But I do not have Nikon bodies now, so did not tried myself.

Did anyone try this hack? I like to remove the video time restriction but I an hesitant to ruin my D7000.

@macmanar: you won't gain anything from uncompressed. See: http://blog.micahmedia.com/2011/06/24/bit-depth-part-2-of-3/

I was shocked to find that even the "lossy" compressed raw held no less information. Fact is that these sensors still put out less than 12bits of DR.

So please devs, unless it's a really easy switch to flip, extra raw settings should not be a priority, since they are pretty much useless. The default configuration in this regard captures all that the raw mode can and gives you the best buffer performance. Anything else is just unnecessarily slow and takes up more space on the card. It's a sales feature on the upper cameras, not a practical one.

@Curunir

We'll see.

Nikon J1 V1 - 720p 120fps :-) Or even 100 fps.

Its already got an excellent 400fps 640x240

@opsx

Look at FAQ here (look at top menu links), just replace URL to download firmware from.

When saving patched firmware, what are the rules for altering the file name?

Build in rules allow to change version part of the file name only.
You can try and play with it.

This is starting to become an exciting thread.

@Moose

How about download firmware, NTool and look at the hints?

Otherwise most questions are quite strange.

I made tool aimed at end users.

https://www.personal-view.com/gh1hack/ntool2.zip

Unlike previous tool, it uses full fledged PTool engine and easy to run on Mac also (using Wine or WineBottler).

Based on some work by Simeon.

you dont read my posts do you? or is it just hard to comprehend what you read? not sure if trollan....

aperture preview with the live view turned off works because the mirror drive isnt fully cycling, it only does one step forward, and back again. its more of a hack done by nikon engineers to add this feature and save money. as soon the mirror is locked up this wont work anymore because the motor has to hold actively the mirror in place. this is why you have to fully charge your cameras battery when you do a sensor cleaning, so the motor has enough juice to hold the springloaded mirror in place for the whole time

aperture preview does not work in live view because the mirror is locked up, and you need a full gear cycle of the mirror gear box to cock the aperture actuator again.

i even made you that video to demonstrate the aperture preview behavior without and with live view.

you just like to believe in wizardry, and that some hack would materialize a 300$ electromagnetic linear stepper motor in front of the mirror box, when theres even no room for one.

the d7000 is so densely packed , they just managed to cram the shutter curtain release drive,

and a mirror box motor into the body, other cameras mostly dont even have a dedicated shutter release motor, doing all of the operation with the mirror box drive.

the rest of the free space is occupied by the relatively big dedicated screwdriver motor and its gearbox to focus AF lenses,

and there is one more electromagnetic solenoid on top of the body, visible when you take off the top ,which is used to actuate the black hook to release the pop up flash.

here is a pic of the mirror/aperture actuation mechanism located on the right side of the mirror box. the side facing right is the front.

;the blue arrow points at the central pivot mount, the whole mechanism rocks around that.

;the red circle marks the spot where the gearbox of the mirror drive motor hooks into, moving that lever forward and back again.

;the yellow arrow points at the mirror hinge spring, the hinge itself is surrounded by that chrome spring above, forming the brake assembly.

;the pink dot marks the contact point of the mirror to the yellow mirror pusher connected to the center pivot. the mirror pusher will only move if the gearbox coupling will move all the way. a quarter cycle will only actuate the aperture

;the green transparent bar is covering the aperture actuator lever pusher, not the lever itself, it is covered by the lens mount frame. the whole assembly is vertically covered by the mirror drive motor, with its gearbox at the bottom

there is nothing more to that. its a simple, reliable, compact and cheap mechanism, used by nikon since decades, even before digital cameras.

only d3´s , d4´s and the d800 got gifted by nikon with a relatively expensive electromagnetic high speed precision actuator and a redesigned mirrorbox which r&d costs are partly reflecting in the prices of these units

but since im throwing facts against your believes wall here, i see no point discussing this with you anymore.

@Simeon

i guess its all about not having to turn off and turn back on live view. like having a real time preview of the changes. i haven't seen the necessity yet to be able to change the aperture electronically on the fly while filming, it just looks bad, cant imagine what it would be good for. i still say if you want to be serious about filming you buy non G , fully manual lenses.

you wont use auto focus while filming anyways.

changing aperture is easier.

and the build/image quality is mostly better.

@Micah

dont worry, there is no bubble to burst.

you are using a manual aperture lens in that video, the actuator lever on the D7000 is spring loaded, alowing it to get pushed back when the aperture lever on the lens is pushing against it so the camera gearbox would not be damaged. it is locked in place, but connected to a spring alowing it to get out of the way when pushed by outside force. it cant move on its own once the mirror is locked up.

of course it is true that the cpu in the lens is transferring the information to the camera so it shows up on the screen or in the viewfinder, but that is just outgoing info from the lens,

this aperture data readout even works on manual aperture lenses without cpu. the D7000 has this little movable notch on the bayonet mount, just a little bit above the white dot you use to line up the bayonet when attaching a lens, which is pushed by the aperture ring on non cpu lenses when you twist it, telling the camera what aperture is set right now.

thats why you set your lens aperture to the smallest setting when attaching your lens or that notch would not be operated correctly when turning the aperture ring. the cpu in the lens, or the notch for non cpu lenses are PASSIVE read out instruments. it has nothing to do with the camera actually operating the aperture.

i am talking about G lenses without aperture ring, which have to be set by the front dial below the shutter. these lenses are using a slap aperture lever,which is operated by the camera, it has to be set and slapped by the mirror mechanism. take your D7000 apart and see for yourself, its connected to the same motor drive as the mirror. im not naysaying here, im just pointing out the facts.

grab yourself a G Lens, go to aperture priority mode in live view, because in manual it will do nothing at all with the aperture , and try to set the aperture in live view using the front dial, you will notice it does not change the aperture when you look into your lens , until you turn off and turn on live view again.

the reason for that ive stated in my previous post, you will see the exact same behavior, which is connected to the same reasons ive already posted, but let me explain it again, just for you.

nikon is using a mechanical lever for controlling the lens aperture diaphragm on G lenses, and manual aperture lenses with CPU which have a aperture lever. Canon and Olympus DSLRs and all mirrorless cameras use electrical contacts and in-lens motors for this.

the most simple and cheap implementation of the mechanical aperture lever is by a mechanical coupling with the mirror mechanism. live view is obtained in these cameras using the same sequence as when taking a picture. OK, the D3100, D7000 and D5100 have the means of keeping the mirror locked up during live view shooting, but the rest of the mechanics are working like during regular shooting.

you can see the aperture lever slap on the left side of the mount going up and down, operating the aperture with each gear cycle of the mirror

the sequence when entering live view is:

1. aperture is stopped down to the shooting value, mirror is up, (like when taking a picture)
2. first curtain of the shutter travels down

suppose now that you want to set a different aperture value to the one set before entering live view. you cannot vary the aperture during the taking of a picture with these cameras. the mechanical lever does not have a separate motor, it must wait for a new mirror & shutter gearing cycle. that means completing the cycle, i.e. closing the second shutter curtain and taking a shot, which is in fact almost the same thing as exiting and re-entering live view. you can see the aperture control lever moving only during these steps.

so, even if the mirror is kept up in LV, the aperture is behaving like during normal shooting, showing that the rest of the mechanical connections are well in place.

when taking a picture in LV the sequence is: 0. (mirror is already up, the aperture is already stopped down.) 1. shutter closes (second curtain travels down)

1. aperture opens all the way (like you have taken a shot and you need to look in the OVF between shots) - now the shutter is re-cocked

2. aperture closes back down. (now it will close at the value set previously when in LV)

3. shutter opens and closes.
4. aperture opens all the way back up (again)
5. aperture closes back down.
6. shutter opens, live view resumes.

the only Nikons that can vary the aperture in live view are the Nikon D3 family; the brand new D4 and D800. These more expensive cameras have a separate electromagnetic actuator for the mechanical lever.

on the D7000 this is not a software lock, it is a mechanical limitation.

There are tables the refer to the jpg's, not all are table driven. For the D5100:

JpgTableTypeA(0x054258, 0x054260);
JpgTableTypeA(0x055de4, 0x055EEC);
JpgTableTypeA(0x2A5898, 0x2A59F8);
JpgTableTypeA(0x2a66D8, 0x2A6770);
JpgTableTypeA(0x7c5a34, 0x7c6254);
JpgTableTypeB(0x38e7b0, 0x38e8d0);
JpgTableTypeC(0x38e8d0, 0x38E998);
JpgTableTypeD(0x392F90, 0x393320);

were:

JpgTableTypeA is 8 byte block, {pointer, length}
JpgTableTypeB is 12 byte block, {dummy, pointer, length}
JpgTableTypeC is 20 byte block, {dummy, pointer, length, dummy, dummy}
JpgTableTypeD is 16 byte block, {pointer, length, dummy, dummy}

The addresses are all memory space, not file space references

@scev0la

How about sharing your info here?

you're storing into JPEG 1 extra byte at the very end of the file that does not belong there.

And? Right now tool is suitable for viewing only, so this small bug does not cause any problems.

@scev0la

It uses special algorithm for extracting JPEG files. No directory inside exist.

@Marc_X

this one? http://narod.ru/disk/4848449000/D200_IMAGE_ADJ_01_25_06.rar.html

@micah

you are wrong again.

the D800 is mechanically a complete different camera. they built it with a dedicated aperture drive motor.

on the D7000, the aperture wheel in live view mode does NOT control the aperture in real time, it is just changing the aperture value on the screen which has to be enabled by turning the live view off so the mirror comes down, and turning live view back on, so the mirror mechanism will CHANGE and hold the aperture in position you have set in live view. as soon the mirror is up, the aperture can not be changed anymore.

only the value on the live view screen is changing.

not the actual aperture.

you have to disable and enable the live view to use the set aperture

also , aperture preview does only work when live view is not enabled. means the mirror has to be down for it to work. the aperture is set by the mirror mechanism as first step before the mirror even moves. the aperture preview stops right there, before it even actuates the mirror.
the d7000 has 3 motors, 2 motors in the shutter mechanism, one for the mirror mechanism and aperture, one for the shutter curtain only. and a slow, quite noisy AF motor that is used to drive the focus on on older lenses without AF motor.

i took a broken d7000 apart, and be assured, there is mechanically no way that the aperture could be changed dynamically in live view. you would need a complete different mechanism or in this case the new D800 which was made with video in mind, and being able to set aperture in live view

Sorry for my question, but I have Nikon d5100 and what can this tool add into functions of my camera,заранее спасибо.

How long will it take for a hack?

We are hunting for small clues, in our spare time, for the fun of it. As far as I can tell Vitaliy has his hands full on the GHx work.

Why is it not being doing here?

This site seems very focused around the good work being done on the GHx hacks. We didn't want to distract from that, or have the established community questioning the progress, when we are much further behind in the understanding curve, of how our firmware works.

I really like Stuge's post above, we are not lacking it idea's that we can't already do. Once we have cracked open the Rubik cube, and start getting some win's then we can talk about what other people would like. But honestly, until that point in time, I couldn't give a hoot what other would like done. Help sure, and by help I don't mean ask how you can help. Just out right help or don't help.

So yes, 2-3 years sounds about what to expect. Aka, buy the camera you want to do what you want now, and if somebody works out how to give you more for free at some time in the future, then that's awesome, but base your actions on what is currently available, as there is no promise that anything will be done.

my comment is not abount naggin but to have the idea of timeframe. So I wondered if anyone had any clue as to how long it may take for thing to happen.Otherwise I can buy another camera with 60fps.

Any idea when we will get a hold of 60fps in d5100 or any hack for that matter?

Shame you're too busy.

I'm looking for a longer Exposure Delay (currently 1-2s) and introduction of "proper" RAW. Rather than the bastardised Nikon NEF format. :)

Any updates?

@el_guero In Aperture Priority Live View mode on the Nikon D7000 and D5100, you can turn the dial and the aperture setting on the LCD will change. However, the lens aperture will not actually be changed until you leave Live View mode or snap a photo. This is a long-known pitfall of Nikon's Live View mode and it's good to hear that it has finally been fixed with the D4.

@mikus : check your pm for the explanation of an hack process, in french.

mikus, no hack.

hack is possibly possible, but uncertain if entirely doable.

check again next year :p

@ Micah: the mechanical limitation is how the aperture arm is operated, on the d7000 it is using the same motor used for the mirror up/lock function. thats why you have to disable and re enable live view , to get the mirror down, so on the way up the new aperture setting takes effect, they did not do the same for the D4, the D4 is not the D7000, it has a dedicated aperture drive not connected to the mirror. its nothing you could fix with the software.

by neogene "My only missing for d7000 is the lack of ability to change aperture during video recording"

sadly this is mechanically not possible due to how the d7000 aperture operating mechanism is constructed, it is not a firmware fixable thing, you better get some manual aperture lenses, or get a manual aperture ring

Hi !

I just wanted to know what are the current progresses on the D7000 hack. Is there any news ? Thanks for the work you've done so far.
