Nikon Hacker making progress - Higher bitrate for D7000 D5100 D3100 and D800

I have the bitrate hack working on the D800 at 54 mbit/s

Recording is fine, playback in camera does not work but works fine on the computer
 
wow

@lars
would you like to share a little bit of footage?

thx to all, maybe the world is a little bit better now...
honestly.

(I luv the 800. takes almost two years, but now we are getting slowly a great team, my nikki and me. )
 
I have a little sample clip here straight from the camera no editing, I still have to make some comparison clips between standard 24 bitrate and 54.

The way it works is you upload the firmware with the hack for 54 and then the movies will record in 54 mbit, when you want to switch to 24 mbit you have to install the stock firmware.

this can be done quite well if you have two memory cards and install the different firmwares on each card, this way it possible to switch on location between the different modes.

I hope we see D7100 being patched soon. I want 50mbps. That is good start for me. Would increasing the bitrate minimize fpn and banding?

I doubt it would resolve the banding since it is also present in RAW photos at low ISOs and in low-light environments
 
This worked absolute wonders on my D3100. No more obvious motion artifacts in fast-changing nightclub/stage lighting. I'm actually thinking about sticking with Nikon for video, knowing that higher bitrates are going to be possible on some of the other bodies I'm looking at. I still want a BMPCC, but at least I don't think I'll need to switch to Canon for shallow DOF video. :D
 
I tested the 54 mbps hack, runs very stable on my D800, shame about not having playback but the visual improvement is worth it. Honestly with movement it is a vast improvement.

Here's a sample, tried to get movement/bright highlights/skin tone so you can see the improvements the codec makes. Shot at ISO 400 1/50sec with Nikon 105mm f2.5 AI. Just a quick shot on Neutral, will post samples with FLAAT profile and properly lit when I have time.

Working on a short advertisement right now, will probably shoot it with this hack rather than the base codec. Good job nikon hacker!
 
I have had the hack on my D800E for about two weeks now and had no problems at all. The footage feels a bit more highres because the noise gets more detailed and less compressed, and I suspect apps like NeatVideo will be more effective. Great work!
 
Noticeable improvement in image quality on my D800 using the 54mbps hack, more so at higher ISO's. Notice I lost about 10 min of overall recording time - is that a side effect of the hack?

Yes, there is a 4GB recording limit, so the increase in bit-rate proportionally reduces the available recording time.
 
I just read there will be an option in a new version of the hack to switch between normal and high bit-rate right from the nikon menu.
This would allow you to change quickly if you wanted higher quality or longer recoding time.
 
Just so I understand, if im recording from my d800 using A blackmagic shuttle via the hdmi then there's no benefit to this firmware hack, correct?
