Hello everyone, in a few days I'll have my new flaming NX 300 :-) I think it's a great camera; video, to my eyes, is at least on par with pana GH2/GH3, even with its default codec compression; so I think this toy has a great potential to shine. Is someone starting to work on a firmware hack like the great work Vitaliy_Kiselev & Co have done for pana? I would like to try for myself, I'm an electronic engineer and I'm good enough on programming (a little of assembly code programming done on PICmicro, C, C++ and Java programming) but I've zero experience on this specific hacking firmware argument. If someone can give me some reading to start from, maybe I can try, with the collaboration of someone else interested on this topic, to start to do something.

Vitaliy_Kiselev where are you? :-DD

There are build and install guides for the firmware on the samsung webpage. Just on the right side.

Did you make suitable firmware using them?

Can the video recording limitation ported to NX30?

Anybody in this forum did the hack yet for the NX300? Curious, as I own one.

Yup!

@IronFilm

It seems that method used for newer cameras also works on old, check top post here.

@superlost2

I think that you must look at the info in top post, by idea dev menu must be similar.

Why people here are not intested on the amazing improvements that some guys (Vasile, Otto, Chant..) are doing on the nx1 and nx500?

In little time they disable the time record limit, are testing higher Bitrates and many more things to come (maybe a Magic lantern like..).

We could at least, update this topic... Nobody cares about the nx300 anymore.

The bitrate hack has been unified for NX1 and NX500. http://www.dpreview.com/forums/thread/3989988

Look like GUI hack with multiple hacks at once is up next.

I've seen a couple of commenters say they've ran the high bitrate hack and have recorded 30 minute 4K clips without any issues.

@chopnshoot

For now it is just scripts that toggle specific RAM address, not real firmware hacks.

Couldn't really find this...what is the highest bitrate that has been achieved so far ? Anyone crested 200mbps?

I think it is 160Mbit, but it is HEVC, so similar to 250-270Mbit H.264 of GH2 kind.

Let's hope for good progress here.

160 mbps vs 80 mbps

Most people seem not to understand how to compare.

Does this improve slow-mo bitrates and quality as well? Most of the NX1's normal modes are decent quality except for the slow-mo, it has a noticeable drop in quality.

yes.

@samuelcabral

I got NX500, will get it quite soon, will try to make some sane guide and look at this.

The quality looks pristine, wow that's clean. A shame that Samsung seems to have abandoned this market. They got things 95 percent right with the NX1.

Is there any method for disabling the crop on the NX500 in 4K? If that's doable, then I'm gonna have to pick one up.

I think they have no idea.

No.... not doable Isaac. As far as i know, you can get 2.5k with no crop.

All that they done for now is just switch mode numbers. And bitrate.

Making no crop 4K require understanding all mode settings difference and initializing.

So, may be it can be done.

I hope some one will post a dummies guide step by step video on how to adjust the nx1 bitrate.

Any update on NX300 hacks, I would like to adjust the bitrate of the 24p mode to match the bitrate of the 60p mode...

Nice to see a few nx300 users here. I recently (after having this camera for 2 years now) discovered some major bugs in my videos after watching them back. I noticed what was flashing in objects or this weird macroblocking going on!!! I looked the problem up and found out that samsung messed the settings up for the codec and its on a low setting instead of high. I cant remember the specifics now, not pleased though and because these are discontinued I doubt we will get any firmware fixes.

Man I would love to see someone hack this thing and fix the firmware on it, I doubt this could be fixed with a script? I downloaded the open source and peeked around but its hard to understand that stuff if you dont know what your doing.

Guys who work on it made progress by making it work without quite complex Bluetooth usage for hacks activation. Note that video bitrates is already implemented this way and work with latest firmware.

@DrDave

From practical standpoint for single camera - GX85

For fun and drive - NX500, last of its kind, http://www.ebay.com/itm/Samsung-NX500-4K-Video-Record-Mirrorless-Camera-k-w-16-50mm-Zoom-Lens-Black-/331831874089

I really hope for hack making non cropped mode available, as well as good bitrate 2.5k.

anyone have any idea if this would work on an nx1000? I have a gh2, gh4, and a g7, but having another angle would be nice for some of the jobs I do, and I have an nx1000 lying around.

NX3000 has really good internal design

Main board have simpler and more integrated result compared to any Japanese company (and Panasonic is still leader among them).

Plus they also throw out all flash related things.

Are you sure what you must get image?

Development has slowed only because one guy went on vacation for July. There are two camps that work mostly separately.

This guy: https://www.facebook.com/NXKS2/ and the other guy, vasille, who is on vacation mostly posts here: http://www.dpreview.com/forums/1001 they both post to http://www.eoshd.com/comments/topic/19099-petition-for-samsung-nx1-hack/

• look in the last 3 months of post to that thread and you can read the whole history.

they both upload installs to here: https://github.com/ottokiksmaler/nx500_nx1_modding With a little effort you can find the readmes and install instructions for both.

the nxks2 guy has a safe installer and concentrates on lots of features. He may have just enabled 4k60p output through hdmi. But more tests are needed.

Vasille, has a dangerous first install(not really if you follow instructions) that needs to be done only once. Features are installed with a second safe mod install. All updates are of the second kind and safe.

Both uninstall without issue. There are nx1 and nx500 hacks with small differences.

Among the rather stupendous accomplishment(especially since as V says they don't have any firmware rebuild)

• both hacks removed 30min video limit
• both can increase bitrate from 4k at 100mb to a consistent 160mb. More is possible but can cause lockups.
• bitrate can be increased for every resolution setting the camera supports- including 1080p 120fps which can now record at 100mb/sec
• focus stacking
• nx500 silent shutter

and some more stuff that is constantly being worked on. There are some differences between the nx1 and nx 500 mods.

both installs are memory resident and stay without needing to be on sd card or to be reinstalled after battery pull. Same with settings.

Both have a gui with buttons that appear with certain button presses on the camera. Changing any settings is easy. Vasille's gui is faster. Nx-ks has more features(mostly bells and whistle type) he adds to all the time.

I've installed and uninstalled both several times. Nowadays I stick with Vasille. He takes his time and is working on some pretty sophisticated stuff that may or may not work out. That's mostly personal preference since I never use a lot of the minor features the nx.ks hack has.

All of us in the community don't get why this isn't getting more attention. Of course since samsung abandoned the cameras, well...

For myself, I only jumped on it after the nx1 was abandoned and hit that first panic price drop at camera stores. I got the nx1, the 16-50s lens the 50-150s lens and the battery grip for something like 40% off what it initially sold for.

I still thing the nx1 sensor is an absolute beast. I'm not sure there is a better hybrid sensor. I take a lot of stills and with a good lens, the nx1 is an astounding stills camera. That's like a bonus. The hacks have no effect on stills themselves.

The hacks are not as professional as the gh2 or magic lantern. But they're pretty good.

I'm sure they are open to your help, V. As far as I know there are only 3 guys doing this with no firmware dump to help. But you\d know far more than me about what's required. If only someone from samsung would sneak them the code of this dead camera...

Does anyone know what, if any, are the differences between Kino Seed's NX500/NX1 hack and Vasile/Otto's hack? I was following their collaborative efforts on dpreview, then the suddenly diverged paths. I've been following Kino Seed's work on Facebook, because his installs and GUI are user-friendly. But has anyone tried the other hack team's work and can comment on it?

Thanks @Vitaliy_Kiselev. I had that impression. I'm not yet done exploring all the features of the NX-KS hack, and I wonder about applying different hacks to the same camera, but I have multiple NX500s so I may experiment with Vasile's on those. I'll look for the earlier post you mentioned about how to install it. I remember starting the process but got stuck on the telnet interface connection.

what sd cards do people recommend for the nx500 NX-KS hack? I've tried the Transcend uhs 3, class 10 64gb, which works perfectly on my Panasonic GH4, and worked with my hacked gh2, but I'm only getting 3 minutes on the time counter, and it stops recording after 9 seconds saying the card is too slow. Any advice?

Note that second hack thread is kicking and improving still

NX300 dev menu

1. Create a text file named nx_dev.adj with smart_camera content, length should be exactly 12 bytes.
2. File must be in the root of SD card.
3. Put SD card in camera.
4. Set wheel to Auto.
5. Power on the camera.
6. Press in succession: down, OK, up, OK, right, press and keep pressed the exposure compensation button, press and release OK, and now release the exposure compensation.
7. You should see the new menu on the screen.

Anyone got a link for the nx300 firmware?

1.45 Hacked for recording time limit and file 4gb limit. Does dev mode limit removal do this anyway?

@cilsinan273

No.

Just buy used NX1 (or NX500 if you want small), this is my personal suggestion.

With good lens it is now overall best camera option.

Can we never find such a setting in open source codes? Maybe there may be lines of code, files, commands or similar things that write video recording formats in the documents in the nx 300 open source code .tar file. you never know. Or you may have encountered it...
