How do you increase Nikon's bit rate of 20 Mbps?

Hey Everyone,

In my last post, some people brought to my knowledge that Nikon's 20 Mbps bit rate is excellent.

I just wondered whether (like the Canon hack) if you can max out the bit rate with Nikon DSLRs.

If so, what is the procedure?
 
Are you asking how to get 20 mbit/s on a shot? If so, then should high detailed subjects like trees with foliage.

If you are asking how to raise the bitrate, you would have to hack the firmware (not an easy thing to do).
 
Nikon uses a hardware H.264 encoder in the D7000 and D5100 . That's one of the reasons it produces high quality videos at 20Mbps, and I don't believe it can be hacked.

We should petition Vitaly for a hack for increase mbit/s on the D7000 and D5100. He would know if it can be done. Also full manual control for the D5100 like the D7000.

I'm in... I believe that he mentioned in a previous thread that it would be possible...
 
Here is what Vitaliy said about this. It may not be practically doable.

"Nikon D7000 firmware is encrypted.
Dumping them is extremely hard task, as requires knowledge and expirience. And, normally, cost very big money."
 
Oh I could have sworn that I read something else. Disappointing...

Where did you read this?
 
Please hack this to allow more frame rates at 1080p! If there is any chance of focus peaking etc like the magic lantern canon hack that would be amazing too!
 
Nice work, can't wait to see the possibilities of this decryption in a custom firmware. Higher bitrate, 4:2:2/10 bits (Clean HDMI output ?), livewiew histogram and aperture control, 24/25/30 fps, Bigger resolution (2K ?), peaking and so much more...
I may just be too excited about all this. Could this be the opportunity to get a D7000 at least as good as Canons on video mode ?

Thank you so much for your work Vitaliy.
 
like i said on Vitaliy's page, the real key, here, would be to be able to remove the on screen data from the hdmi output. if that's possible, then we could use an Atomos or a Ki Pro Mini to record in ProRes, instead of low-quality h.264. Yes, extra frame rates would be nice, also, but not as nice as losing that extra data.

I thought the hdmi out was a lower resolution?
