http://www.personal-view.com./talks/discussion/3337/gh2-flow-motion-v2.02-720p-reliability-in-auto-exposure-modes/p1

As numerous GH2 owners have discovered, Vitaliy's recent updates to PTool have enabled the newly hacked GH2 to sustain remarkably high bitrates in MJPEG HD mode. What's even more impressive is that the GH2 maintains error-free recording stability at bitrates significantly exceeding those that can be used reliably on the GH1. And where the GH1 struggled to produce FHD-size videos in MJPEG mode, the GH2 can be readily patched to record in any MJPEG frame size, all the way up to 1920x1080p.

The MJPEG encoder's most valuable asset has always been its ability to record each video frame as a JPEG-encoded key frame. This enables it to track high-speed action at 30fps without any of the smeared motion artifacts that plague low-bitrate AVCHD videos. To produce high-quality, detailed key frames at 1080p, however, an Intra-frame encoder must work at higher average bitrates than the GH1 was able to sustain. With PTool's support of the GH2, it is now possible to use MJPEG HD mode to produce reliable 1080p videos at an average bitrate of 100Mbps in sharply-focused, highly-detailed scenes.

The MJPEG encoder also excels in difficult low-light conditions where the AVCHD encoder cuts down its bitrate to minimum quality levels. On the GH1, MJPEG HD mode could be relied on to produce bitrates over 24Mbps even in dimly-lit scenes. With patch settings optimized for consistent bitrate production, the GH2 can maintain high bitrates of up to 100Mbps across the entire exposure range, producing high-quality images under any and all illumination levels. Combined with the GH2's low-noise image sensor, MJPEG HD mode can render clean, gradable images in conditions that the GH1 would have found hopelessly underexposed.

MJPEG image quality with exposure bracketing

Below are 100% crops of two series of four bracketed exposures I took in MJPEG HD mode, patched to 1920x1080 resolution. For each shot, I set up the GH2 on a tripod with a fixed aperture at ISO160, and varied the shutter speed from 1/60 to 1/500 second, producing videos bracketed at one-stop exposure steps. Frame grabs were then composited in Photoshop and saved at maximum JPEG image quality. These scenes were selected as typical outdoor subjects shot in natural lighting, as opposed to shots of extremely detailed foliage. The GH2 exhibited no reliability issues whatsoever, and recorded all videos at impressively consistent bitrates of around 90Mbps.

iPad compatible MJPEG VGA video mode

In addition to MJPEG HD mode, recent versions of PTool have provided patches for adjusting the frame size and image quality of MJPEG VGA mode as well. Unlike the HD 16:9 aspect ratio of HD mode, VGA video mode records with an SD aspect ratio of 4:3. I've optimized VGA mode to produce 960x720 videos at consistent average bitrates of about 30Mbps. These videos are compatible with the maximum-quality download specifications of the Apple iPad, with its 1024x768 screen resolution.

GH2 Patch Considerations

Patches for the GH2 are currently in active development by numerous testers, and Vitaliy has updated PTool several times with exciting new features. The patches in the downloadable PTool INI settings file below have been systematically tested using PTool version 3.61d and have produced no reliability issues to date. This patch is designed and tested only for the fastest Class 10 SDHC cards currently available.

Additional points of interest:

* The 100Mbps GH2 Low Light MJPEG 1080p Patch is compatible with all GH2 cameras, and is switchable between NTSC and PAL modes.

* I recommend using the camera to format your SD card at the start of each shoot, to guard against SD card memory fragmentation.

* Peak bitrates are obtained only with sharply-focused, highly-detailed subject matter. Average scenes will produce average bitrates.

* High bitrate MJPEG videos may not play back reliably in-camera or on low-powered computers.

* If shutter speed is set longer than the frame rate (e.g. slower than 1/30 at 30p), low-quality video files may be produced.

*** WARNING ***

The 100Mbps GH2 Low Light MJPEG 1080p Patch will not work properly with previous versions of PTool. My thanks once again go to Vitaliy Kiselev, for his pioneering work on PTool, and to cbrandin for his invaluable Stream Parser tool.

The best way to insure that you have the latest PTool release is to download it directly from the following link:

Download PTool here: https://www.personal-view.com/faqs/gh2-hack/ptool-software

100Mbps GH2 Low Light MJPEG 1080p Patch Settings File:

For use with PTool v3.62d and above, I've prepared anamorphic as well as standard aspect ratio settings files:

* For use with standard lenses, the standard patch will produce two types of MJPEG 30p videos:

HD mode: 1920x1080 HD videos, with peak bitrates up to 100Mbps.
VGA mode: 960x720 iPad-compatible videos, with peak bitrates up to 30Mbps.

* For use with anamorphic lenses, the anamorphic patch supports two different squeeze ratios:

HD mode: 1920x810 videos for 1.33X anamorphic adapters, with peak bitrates of 100Mbps.
VGA mode: 2160x810 videos for 2X anamorphic adapters, with peak bitrates of 100Mbps.

These zipped INI files can be used to apply complete patch settings to firmware loaded into PTool. To use, unzip the INI file into the same folder as the PTool application. Launch PTool and load the firmware for GH2 v1.0. The settings contained in the INI file will automatically be installed in the "C" button at the bottom of the PTool main window.

Note that with the following PTool Settings files, you may at any time re-install the original Panasonic GH2 v1.0 firmware into the camera. You may also copy each type of patched or original firmware to separate SD cards, and use them to quickly switch between patches as often as you like.

GH3 hdmi not outputting 1080p despite viera link=off & hdmi mode=auto https://personal-view.com/talks/discussion/9915/gh3-hdmi-not-outputting-1080p-despite-viera-linkoff-hdmi-modeauto Wed, 19 Mar 2014 06:59:56 +0000 andrevanberlo 9915@/talks/discussions Hey Everyone,

Just got the ultrastudio mini recorder and started testing with the GH3 hdmi out. It sends 1080i50 when it is in auto mode despite the fact that I have rec quality in 1080p/25. 720p/50 is also possible but no 1080p.

I checked the FAQ for GH3 and there it says:

"How to make the Lumix GH3 camera deliver proper, recordable 1080p over HDMI: Deactivate VIERRA Link and Set HDMI Output to AUTO"

With me it doesn't work. Does anyone have an idea how I can do this or are 720p and 1080i the only possibilities?

Thanks

Andre

PS I have installed latest firmware on my GH3

Field monitor (only) with features like Atomos Shogun https://personal-view.com/talks/discussion/13632/field-monitor-only-with-features-like-atomos-shogun Mon, 31 Aug 2015 10:40:05 +0000 JackBayer 13632@/talks/discussions Hi!

As I browsed the web on the advantages (or lack thereof) of using a Shogun with my GH4 I realized that I'd really like to have all those software features on my field monitor. Since I am not going to need external recording I was a monitor-only solution comparable to the Shogun. 1080p would be nice also.

Any ideas, anyone? Thanks!

Edit:

@Vitaliy_Kiselev Here's a list of my desired features (could have thought of that myself...):

  • Custom frame guides
  • 1080p
  • IPS display (or whatever technology bright enough for outdoor usage)
  • normal HDMI port (not mini or micro)
  • waveforms, RGB levels and histogram would be nice but are not a necessity.
  • focus peaking
  • 7 or 8 inch
  • a nice user interface

It doesn't have to be cheap (it couldn't be).

How far have we come with Video Cameras? https://personal-view.com/talks/discussion/11818/how-far-have-we-come-with-video-cameras Fri, 21 Nov 2014 10:05:10 +0000 mpgxsvcd 11818@/talks/discussions I was thinking about the state of video cameras when I first got into making videos in 2003 when my son was born. It was a pretty sad state back then.

Everything was interlaced 480i or at most Telecined 480p in a 480i container. MiniDV was all the rage and HD was a figment of our imagination.

I started with a Canon mini-DV camcorder in late 2003 that shot 480i(720x480). It looked great on my 480i Tube TV. However, it was absolute garbage once you deinterlaced it for computer use with Progressive displays. I sold it almost immediately swearing that I would never buy another interlaced camera again.

So I waited and waited. Everything new was 480i. Even when HD TVs came about the HD consumer cameras were still interlaced 1080i. Then finally the Canon S1-IS came out in 2004. It was a little known jewel. It shot wonderful 480p @ 30 FPS for up to 1 Gigabyte. The nice thing was that it supported the MicroDrive compact flash cards that at the time went up to 4 GB for about $200.

http://www.dpreview.com/reviews/canons1is/

That camera revolutionized video for me. At the time everyone asked why I was getting a still camera for video. They all said “Why don’t you get a proper camcorder for the job”? I said “The camcorders are all interlaced and this is progressive”. They looked at me like I was speaking Japanese.

I loved that S1-IS and used it for several years as my main camera. Sure it was only 480p but it was good solid 480p @ 30 FPS and it used a decent bit rate(For that time period). The S1-IS also had a really bright F2.8-F3.1 lens on it. With a 10x optical zoom it did everything I wanted it to do until I saw what the 1080p of the 5D MKII looked like in September of 2008.

http://www.dpreview.com/reviews/canoneos5dmarkii

Reverie, blew my mind. I couldn’t believe that you could get such cinematic shallow depth of field and dynamic range in digital video. In addition the resolution seemed astounding. At the time I couldn’t imagine ever needing more resolution than that.

http://www.learn.usa.canon.com/galleries/galleries/sample_videos/reverie.shtml

I came as close as you could get to buying into the 5D MKII with a complete set of lenses. I saved and saved until I was finally ready to pull the trigger by the fall of 2009. Then something caught my attention.

A little known camera maker (At the time) called Panasonic had developed a 720p camera that was actually really small. It was called the GF1 and looked too good to be true. It could use any lens ever made with adapters. It wasn’t super expensive and all the manual focus lenses for video were super cheap on ebay.

They also had the mighty GH1 but it was hard to find without the super small aperture 14-140mm lens. By that time I had come to realize what I loved so much about the Canon S1-IS was that its lens was relatively bright. Just like I had with interlaced video I swore off super slow mega zooms.

However, I simply couldn’t resist the GF1 with the 20mm F1.7 lens. I bought the GF1 on day one and never looked back. I bought every large aperture MF lens I could get my hands on and loved them all. However, those lenses were heavy when it was all said and done. I realized why full frame wasn’t really considered to be portable back then. 5 or 6 lenses added up to a lot of weight in a backpack even though the camera body was so light.

By that time 720p had become old hat and M4/3s had more than just a few native lenses. They had some fast primes like the new 14mm F2.5, 25mm F1.4, and the 45mm F1.8. Auto Focus was improving in their newer cameras and I found myself wishing for more.

I finally broke down when the GH2 was announced in September of 2010. It was finally the camera that seemed like it could do it all. 1080p video, ETC mode for endless reach, and it was hackable. Those were the good old days. We ALL spent countless hours eeking out every last ounce of bit rate and reliability that we could.

http://www.dpreview.com/products/panasonic/slrs/panasonic_dmcgh2/review

I even gave up on the MF lenses. I had all of the fast primes at that time and MF wasn’t as cool as I once thought it was. I was much more content to just let the camera do the focusing for me. After the firmware update for the GH2 added 1080p at 30 FPS and much improved AF I sold all of my MF lenses for a nice telescope.

Honestly, the GH2 was probably the camera that I could have stopped at and lived with for quite a while. It did everything I needed it to do and did it quite well. However, the hacking had sparked something in me that made me always look for that little bit extra. I went on to buy the GH3, GH4, LX100, and the 35-100mm F2.8 all on the day that they came out. Each one offered a little something extra that I thought made it justify the extra cost. I finally have 4K @ 30 FPS and 1080p @ 96 FPS and the 4K photo from video mode. I couldn’t have ever possibly imagined those things when I first bought the S1-IS.

Well actually I did predict the photo from video mode way back in 2009. It wasn’t an acceptable thing back then to predict that video could one day replace stills. In fact I still don’t think it is acceptable today either.

http://www.dpreview.com/forums/post/31728454

So we have come a long way in video cameras. I wonder what is next. How much farther can we go? Will it be as big a leap forward as it has in the past? Will I still want to spend my money on upgrades in the future or will I finally be satisfied with what I have now? Who knows? Only time will tell.

Please post your stories with how you got started into video and where you are with it today.

Premiere Pro CS6 reducing resolution of all exported video https://personal-view.com/talks/discussion/9353/premiere-pro-cs6-reducing-resolution-of-all-exported-video Wed, 15 Jan 2014 00:52:58 +0000 IVIaverick52 9353@/talks/discussions So this is the first I've seen this happen and I can't find any info online. Basically when I export a project in premiere I get severe aliasing and overall reduced resolution, no matter what setting. Exporting 1080p in MP4, DNxHD, uncompressed AVI all give the same results, resolution that's closer to 720p than 1080p. The odd thing is I've compared the out of camera MTS files (and even the DNxHD converted files used in the project) to the outputted files from Premiere, and they look totally normal. I'm using a GH2 with Drewnet T9 and it's been great but this is really stumping me.

My current workflow is: MTS files into AE > converted to 2.33 aspect ratio (1920x824) DNxHD format > footage imported and edited within Premiere Pro > exported as 175 bit DNxHD 1920x1080 master file. Note that the 2.33 conversion is strictly letterboxing via composition settings in AE and not altering the pixel dimensions (as those 1920x824 files don't show the pixilation).

One thing I noticed was that when I expand the video feed in Premiere it shows the pixilation that's outputted in the final format, but I wrote that off as simply being reduced resolution for real time playback that wouldn't translate to the final video. Also the preview remains pixilated even with no effects applied (only effects on clips are quick color corrector, Neat Video, and shadows/highlights).

Any insight would be greatly appreciated. I've included a still of the 175 bit DNxHD final video, and a matching frame of the original MTS file straight from the camera. Ignore the top and bottom margins, but look at the high contrast lines like on the Marshal logo, and the metal frame of the B-52 amp below it.

I backed this Kickstarter project. At a minimum I was happy to get a lightweight portable second screen for my laptop on the cheap. But I'm wondering if it could be used as a field video monitor. It has HDMI input. I am guessing the power would need converted to run on a battery in the field. I sponsored at the level of $135 which gave me the option of 13, 15 or 17 inch. I was thinking of I were to use it mounted to a camera rig the 13" would be nice.

Any opinions?

medium (15") FullHD monitor for focus puller https://personal-view.com/talks/discussion/6443/medium-15-fullhd-monitor-for-focus-puller Tue, 19 Mar 2013 16:31:28 +0000 Psyco 6443@/talks/discussions I was looking for quite some time for a medium size portable monitor with HDMI input and 1920x1080 resolution. I need it for my focus puller to judge focus (using a remote follow focus) on set, especially when doing steady-cam work.

  • The monitor must not be to big, as he will have it right in front of him (some times right on his lap). If the monitor is to big, it would be to bulky and it would be to exhausting for the eyes always looking from side to side.

  • Full HD 1920x1080 is a good thing when judging focus. Using a GH2 with FM2 or Moon, the picture is recorded at a very high level of detail and resolution. Being off focus on the main subject is annoying.

BUT...most of the monitors are either big (>19") or not full HD. Most of the monitors advertised for cameras/DSLRs are even only 1024x600 (which is 16:9 SD resolution, not HD!). Or they are very expensive.

Today I stumbled over this monitor:

http://www.ebay.de/itm/40cm-15-6-LED-FULL-HD-TV-FERNSEHER-DVB-T-PVR-VIDEO-RECORDER-USB-HDMI-220-12V-/380584100436?pt=DE_TV_Martin&hash=item589c948254#ht_13302wt_1141

Which looks quite good for the task I need it for. The biggest downside is probably the 25W power consumption - I will need a big battery mounted to the backside.

What do you think? Any better options?

GH2 - 25P and 1080P? https://personal-view.com/talks/discussion/6119/gh2-25p-and-1080p Thu, 14 Feb 2013 03:37:47 +0000 lmackreath 6119@/talks/discussions Morning all!

I currently have a UK PAL Sony Nex 5N and am happily using it to shoot away at its optimum settings at 25p 1080p. I now have purchased a GH2 in the UK and am aware that I can hack the GH2 and get 25p as well as 24p but with the 25P HBR Option on all hacks I can only see a 1080i option and not a 25p 1080p option?

Could someone please explain to me why this is?..and maybe more importantly does this matter?..will I still get great results using the interlaced 1080i and/or is therr a reason why the GH2 and any of its hacks dont offer 25p 1080p?

I have searched this forum and googled the answer and have seen topics about this but no real definiative answer, if anyone could advise it would be appreciated. Ideally I just want to be able to shoot at 25p in the UK but still be able to get the best resoultion settings which I have always believed to be 1080p?

thanks in advance

I am currently using an old 15" LCD monitor as my preview device, which is not very accurate. I do not have the need for a real studio monitor. what bothers me about this solution is the black level.

Today, still all TVs start with black at 16 of 255 shades as opposed to 0 of 255 shades in a PC monitor. (This is my understanding, correct me if I am wrong) At least, What looks grey on a PC monitor is often times still black on a TV.

I was thinking about getting a small 1080p TV as a monitor, but maybe you have better suggestions.

I am looking for a small Monitor for my working space (maybe around 20") that has TV black levels. Or would you suggest changing that in the graphics card config...?

rajamalik, @coors thanks for testing the setting(s) guys; rajamalik Congratulations for your little b...

Releasing the setting, after very long time working on it, the name and some info see 1st alinea:

I know it was/is a challenge (AQ4 and Q8 in the same setting) for most detailed and lower compression setting and want everything constant bitrate-style and rajamalik asking for the most detailed one every time but here is the release of the "OBS AQ4-Q8 161M-setting exTReme-KAYSERI A-GraDetail" setting, the setting shows (due to using lower compression in the setting, but I believe so you see more), maybe say high ISO, a little bit more noise/maybe artifacts, I did not used 3rd party matrix, but the goal is to get every bit (in this situation pixel) what GH2 is seeing/recording, out of it and see everything yourself when playing back and in post too, and cbr-style bitrates too; (do the rest/editing in post).

Okay it's logical to say when you have an very detailed and low compression setting, on high ISO you see some more noise/artifact etc. but you get everyhing out of the gh2 I believe. But I believe, if an "matrix master" can make a matrix especially for this or similar setting then we get an setting with some reduced noise/artifacts directly on the sd-card itself. But matrix by the way is a subjective matter therefor it is up to you to judge or not judge things by matrix way but settings way. And I did not used third party matrix for the setting.


But, on the other hand: maybe there will be enthousiat users to get/shot/capture, you name it, this way and do rest in post, I think and believe it is maybe some personal taste and this setting is on paper very good for low detailed scenes or for someone always looking for it or exactly want details and seeing that little bit more.

The setting gives you constant bitrate-style bitrates and for example 720p50 give you around 100Mbit-range bitrates, this is high in comparison with some other gop-1 720p50 settings/ and some of the other gop-1 720p setting are not working reported earlier by others I though. Don't forget 1080iFSH(50) is available too and also to try for slow motion with deinterlacing in post for 1080p50, maybe this setting is better then other 1080i also, who knows. (This is for some of you as a fan of deinterlacing 1080i to 1080p50 in post, instead of 720p50 give a try too.)

Suggestion: Maybe, from scratch, a matrix master or a matrix maker can make a matrix to also temper some noise/artifacts, high ISO etc. especially for this setting, but also this setting is for people who get the most details out of gh2 and loves to do things in post...

Setting itself, "OBS AQ4-Q8 161M-setting exTReme-KAYSERI A-GraDetail":

(for me unbelievable to let the setting work with AQ4 and Q8 in the same setting at the same time, "All to detail and low compression" at a such high setting, especially when you know that settings for some mode influences the other mode, but I've got them work together for:)

  • working (/or say, I tested) for the modes => 1080p24H, 720p50SH, HBR, 1080iFSH(50), 80%24L but, with such high bitrate setting it was not easy to get, all the modes above, working
  • for all the modes I've written above, constant i-frames-style (+ b-frames for 720p50), cibf-style, except for 80%24L though it has high i-frames between around 360KB to max around 780KB, average around 600KB, and constant bitrate-style, cbr-style, for all the modes I've written above too, (including for 80%24L mode)
  • tested with manual lens, (auto-lens check for yourself)
  • there is a time-limit 3:45min but every mode is working for me with my setup (sd card and manual lens), so recording and also in cam playback available for, maybe including but not limited to (does mean other modes such as 720p60 needs testing, test for your country, I tested the PAL), the modes from above
  • sandisk 8GB SDHC 95Mbits/s card

some bitrates I've got during testing, setting for 1080p24 is high to the 150M range, but see others very good ones: - 720p50 100M (for slo-mo see 1080i fsh(50) mode too, for using deinterlacing in post) - 1080i FSH (50i) 100M (especially for people who want 1080p slow motion with deinterlacing) - HBR 100M (I think very good one for hbr) - 80% 24L 100M

here is the setting as .zip file attached

1080p/i and 50 or 60fps? https://personal-view.com/talks/discussion/2433/1080pi-and-50-or-60fps Tue, 28 Feb 2012 13:12:39 +0000 willianaleman 2433@/talks/discussions Is it possible to obtain a highest fps than 29.97 or 30 in NTSC 1080p or "I"? I'm looking for 50 or 60fps to record fast motion panning from a fluid head tripod with manual lens.

I'm using Balazer's Cake patch v.1.1 with Ptool 1.63. Thanks in advance for any help.

Best Mac Cross Conversion Software for 720P to 1080P https://personal-view.com/talks/discussion/1897/best-mac-cross-conversion-software-for-720p-to-1080p Sun, 01 Jan 2012 17:43:11 +0000 bigtuna 1897@/talks/discussions
I am looking for the best Mac Cross Conversion Software for 720P to 1080P. I shoot 1080P on the 5DMKII and want to use my hacked GH2 for slomo at 720P. I need to deliver the highest quality 1080P master that I can. What is the best method for cross converting the 720P material to 1080P ?

I have tried transcoding to ProRes 422 720P and then working with this in Avid Media Composer in a 1080P project, final results are not great this way. I have also tried converting the 720P material to 1080P ProRes - the results are not so great either.

Getting an excellent 720P final master, but what is the best way of working with the 720P and 1080P material to get the highest quality 1080P final master file ?


Many thanks indeed !]]>
GH2 MJPEG 1080p 25 fps. https://personal-view.com/talks/discussion/1713/gh2-mjpeg-1080p-25-fps. Mon, 12 Dec 2011 07:00:37 +0000 Athiril 1713@/talks/discussions
Now I went to stock settings (original GH2) for MJPEG with 25 fps, worked. So loaded the LPOWELL 100mbps/night 1080p settings, added 25 fps changed, works on my GH2. I'm not sure if it's merely dropping 5 frames out of every second (don't think it is). But if you shoot 1/25th, not sure if that it'd matter?



I'll try to examine it at some point with some linear motion at fixed speed, and look for 'jumps' in space.

My test file is reported as 75,697 kbps. Or 74 mbps. Which would be 88.7 mbps @ 30 fps, at the same average size/compression per frame. Available recording time is reported as 3m 12s. Recording on a Transcend 32gb class 10.

Test file was shot at ISO 2500, probably a stop underexposed still by the looks, just messing around in indoor light.


I'll do some slow panning on a monopod tomorrow with shutters @ and greater than 1/30th, and upload that.


Also I have gotten sizes a bit above 1080p working fine before too, which is useful I think for stabilising software if (such as deshaker) if you can shooter slightly wider than you want/need, so you don't have to blow up (or blow up as much) back to 1080p frame size for a 1080p output workflow. Combined with 25 fps would be great.]]>
Real MJPEG 1080p resolution. https://personal-view.com/talks/discussion/1424/real-mjpeg-1080p-resolution. Fri, 11 Nov 2011 15:20:12 +0000 pedro 1424@/talks/discussions
I'm not sure is this is the right way to ask a question of everyone on the issue of resolution regarding the Mjpeg codec but I didn't see a category anywhere that pushed this issue.

The reason why I have a concern over this is that I noticed with the ex. Telescopic conversion (ex.tel) on that when shifting between 24H and 720p 60p the image automatically zooms forward a bit more. Since in ex-tel mode the camera is no longer downsampling off the entire 4k sensor it makes sense since this is the equivalent of a digital zoom. It uses a central 1080p sized piece of the sensor and then it zoomed in even further to get a smaller 720p sized piece of the sensor. If I switch it VGA mode it the image will zoom in just a tiny bit more. I can only assume it is at that point jumping into an even smaller 480p sized piece of the 4k sensor.

This is all fine, what worries me is that if I switch back to 720p60p and am thus on the 720p sized piece of the sensor, and then switch to HD Mjpeg, which I have set for 2K (2048 by 1152) level of resolution, the image does NOT, repeat does not jump back out to at 1080p or 2K sized image from the sensor. It's exactly the same. This suggests, in ex-tel mode that as only a 720p sized piece of the sensor is used to film 720p60p mode, the exact same sized piece of the sensor is used to film HD MJPEG mode as well. In other words even if you reset the HD MJEG resolution away from its native 720p settings and push it up to 1080p or even 2K, it may still be only recording 720 level of resolution. In other words its possible the HD Mjpeg system merely upsamples its native 720p footage such that when we assess that footage in quicktime or VLC it will state that it is 1080p or 2K but in terms of literal optical quality we still only have 720 lines to play with.

I've noticed with identical shots I've taken with HD MJPEG 2K and 1080p 2p AVCHD that the resolution was almost identical but I somehow felt there was more clarity off of the 1080p footage. Technically the 2K I had with 2048 by 1152 should have been a bit better, but it wasn't.

Has anyone done a resolution test on the HD MJPEG, 720p and 1080p modes to confirm what kind of resolution we're actually getting off these different codecs?]]>
Is it possible to record 1080x2581 (2.39:1) AVCHD with GH13 or Gh2 ??? https://personal-view.com/talks/discussion/1427/is-it-possible-to-record-1080x2581-2.391-avchd-with-gh13-or-gh2- Fri, 11 Nov 2011 17:24:30 +0000 kronstadt 1427@/talks/discussions The 2X crop factor is the greatest annoyance with GH1 and GH2, which also means that a whole lot needs to be spent on super wide lenses in order to get a shot just wide enough. One way to battle that is to use Anamorphic adaptors, and those cost an arm and a leg, and are very difficult to handle (imagine follow-focusing both the lens and the anamorphic adaptor simultaneously; or imagine having to remove and re-attach the anamorphic adapter every time you change a lens).

It is possible to record AVCHD 1080p (height). But what is the maximum WIDTH of the video that can be recorded with GH13 and GH2? Are we limited to 1920, or is it possible to go wider with some sort of a hack/patch? Would it be possible to record 1080x2581 for example? That's the industry standard 2.39:1 aspect ratio that we get in most Hollywood and DVD productions these days.

If it would be possible, it would mean that those folks who don't have the fortune to afford anamorphic lenses, can still use their existing lenses and produce a picture that is at least in the same aspect ratio as cinema standard (albeit without the oouie flares and anamorphic bokeh). The other major benefit would be that a 20mm lens can be used as a ~27mm, rather than a 40mm.

Is it currently possible? if not, is it in development?

GF1 patch suggestions for progressive 1080 https://personal-view.com/talks/discussion/1106/gf1-patch-suggestions-for-progressive-1080 Wed, 05 Oct 2011 11:49:59 +0000 luckyluca 1106@/talks/discussions I owned the gf1 for a year and decided yesterday it was time to hack the firmware and get fullHD on it. I spent a lot of time looking through the patches available, tips, how to use the ptool and went through a hacked firmware update successfully.

Here is what I'm after:
I am a visual effects artist and wanted to shoot 1080 progressive 24 fps using the fantastic 20mm pancake lens and planning to do tracking and augment the shots with visual effects of some kind. I don't need fast action shooting and am aiming to keep things as progressive as possible at the highest res possible (I'll breakdown the footage into individual frames which I can run on houdini and maya later).

I'm not fully clear whether 1080p 24fps is indeed achievable on the gf1, any help and suggestion on this or potentially the next best option for progressive frames at the highest resolution would be much appreciated.

Also little help on how to enable fullHD and choice of format once the fimrware is installed would be appreciated too

Thanks!
Luca

So what would 1080p @ 60 FPS look like on the GH2? https://personal-view.com/talks/discussion/774/so-what-would-1080p-60-fps-look-like-on-the-gh2 Fri, 26 Aug 2011 08:14:05 +0000 mpgxsvcd 774@/talks/discussions
http://www.dpreview.com/previews/sonyslta77/page8.asp

I downloaded the files from the link above and pulled them into streamparser. They appear to be 28 mb/sec but I noticed that their I, P, B frames were a lot lower than what I have seen for even the 32 mb/sec GH2 footage. Maybe @Cbrandin can comment on whether stream parser would be accurate for the A77 files.

The other interesting thing is that the 1080p @ 60 FPS files don't really look any better than the 1080i files. They are not of the same scene but if I didn't know which one was which I don't think I could tell them apart. Panasonic has already stated that they intend to give the GH2 25 FPS with a firmware update and they have a history of giving older cameras new features(ie: LX3 and LX5 more recently).

I think Panasonic should just enable 1080p @ 60 FPS for the GH2. They have stated that the GH3 is not coming out anytime soon. So why not give the GH2 the same features as the new A77. Panasonic has said that the GH2 is still selling well even though its price is roughly unchanged for the body only. They could charge $100 for a firmware update and give us 1080p @ 60 FPS and PAL users 25p and I guarantee it would keep the GH2 selling well into next year.

1080p @ 60 FPS is probably not as useful as we had hoped it would be. However, I wouldn't mind paying $100 to try it out.
