Awesome, do you have a stream parser so you can compare the two bitrates?  zond 265 worked for me. They have trials as most are very costly. Do a sample with the before and after frame rate and then see what the analyzer says. This is a step for sure!

That is hard to say, might be able to load something like magic lantern, but the way the camera uses the .cpp files firmware wise make it limiting in what can be done. ML uses a modded firmware with a boot flag to enable what they use. But can be added to the list of things to look into. There will probley be a few variations of firmware, I found a log file of what they did to test and try to break the firmware so imitating it could be helpful.

 
With luck  that will be possible! The di-camera-app is interesting. I found the package info for it last night as well. 

 
Flat or log or cine gamma. All similar but not if you know what I mean. My want is for something to be similar to red.

I want to thank all the guys who are working hard for our project to make great cameras Samsung NX1, and younger sister NX500.
Samsung one year ago, has introduced them in the market as spaceships and then abandoned them in our hands.
Internal Technology Samsung nx1 and NX500 (28mp BSI sensor, Drime V and Drime Vs engine processor, HEVC codec) is superior than all cameras which are still planned.
it is my belief to think that the processing power allows recording 4k in 4.2.2. without difficulty or 4k Raw internal recording and beyond.

I have not tried any of the hack yet but I agree that I would prefer to not touch the original firmware and not need to flash anything to the cameras internal memory.
IMO the idea hack (if possible) would be somewhere in between what both of you are doing with the ability to reboot into a separate OS from the SD card.
Chant, from what you have seen do you think it would be possible to do this or do you think you would need to flash something new to the camera?

@raj90 @ricardo_sousa11 you can kinda  already do that by putting settings in EV_RIGHT.sh and similar files and using keyscan utility documented in github repo.

Some interesting tidbits found tonight.

Still looking for the encoder though. To confirm srp or other hardware. But the closer it gets. And then the real fun happens!
I can look into the nx500 firmware deeper after I do the nx1 and see what can be added or changed. I do have a want for a nx500 b cam, especially as a gopro stand in due to them being cheaper! Make everyone want this samsung gear now that they cant get them. Maybe it was samsungs plan all along.
Edit
"HEVC Encoder
%s:%s(%d)> Width(%d) or height(%d) is not multiple of 8
%s:%s(%d)> HEVC[%d] Cfg WH %dx%d %d, BR:%dkbps GOP:%d > size 0x%x > return %d"
the full sensor read out should be possible with this also notice gop setting and bit rate.
 
I will have to look at the encoder.cpp file which is where things get more complicated but this is very good news.

I have a few githubs for other projects and its a good idea. it would be more of a blog, the amount of data I have examined would be too much to try to make sense of, as I said, I was working on this for my own personal goals a few months before I even found this thread.
Ill see if I can create something tangible in the next few days github wise and Ill post up. Alas text cant convey how excited I am as I go through all this info. I had a want for it to be a good system and it has surpassed my expectations. Great things can be done with it. 

Simple "hack" to enable silent shooting in single mode (not CH/CN):
[root@drime5 ~]£ st cap capdtm getusr 117
UserData is ADJUSTSHUTTERTYPE_MECHA (0x750000)
[root@drime5 ~]£ st cap capdtm setusr 117 0x00750001
UserData is set
[root@drime5 ~]£ st cap capdtm getusr 117
UserData is ADJUSTSHUTTERTYPE_ROLLING (0x750001)
ROLLING is full electronic shutter
Now, why Samsung did not enable this in the menu I have no idea... It's fully working in full resolution JPEGs and SRW files.
I have not time to test whether image quality suffers, but it looks OK to me
Could someone check if it works with NX1 as well?
Cheers and have fun,
Otto

Well if it doesn't give them the hits, they're not interested. If this was a Nikon hack....
There's no accounting for taste I find.

Chant, could you please share the SDK? I think we could add it to github ( https://github.com/ottokiksmaler/nx500 ). One place to show actual progress and results of NX1 hacking would be nice (SD sripts hacks/ firmware hacking).

Thats funny. I think you were trying to trol but that is actually the angle i was thinking. 
The article would talk about how exactly samsung has abandoned their camera system yet dispite this their cameras are/were so good that people continue to use them and that people are even able to improve them. The article would also talk about how easy people are finding them to hack and how much potential these dead cameras have. 
My hope is to draw in more people to hacking these cameras to help unlock things like higher bitrates and removing the recording limit. 

Here is a quick video showing the NX1 and NX500 SD Card Hack for Focus Buttons.
This program allows you to record up to 6 focal points, these are stored on the SD card and will work after a camera restart.
This works for photography, especially good for storing infinity focal point to re-use when it is dark for Astro Photography.
Works in video allows you to do focus pulling from one focal point to another.
Thanks again to Otto for all the hard work, All details can be found on https://github.com/ottokiksmaler/nx500
 

The samsung srp research is also to see if thats what they used, but it it was an onboard hevc asic there would be a lot less code for what Im finding if you go by what tends to control hardware. With luck its srp because Ive found examples of it beings used to do a full 8k6p stream with a very small srp block and the drime-v is a very different beast from the exynos.

But ill just leave these excerpts here.
