GoPro Studio Cineform Color Bit Depth Gain?

karl-miller wrote on 11/1/2016, 10:19 AM

From other threads on this forum Ive read that using GoPro Studio to convert Hi Rez video into Cineform can "effectivly" recover two more bits of color depth from the compressed MP4 camera data.  That is, Cineform based video out from GoPro Studio appearently has 10 bits of effective color depth (even though the compressed data from the camera shows meta data saying it only has 8 bits).  

Can this same effective bit depth gain be acheived with any program that converts GoPro MP4s into Cineform, or is there some special magic inside GoPro studio?

Can this same effective bit depth gain be acheived with any program that converts GoPro MP4s into any codec format which has at least 10 bits of depth, such as HDX?

thanks,
karl

It is impossible to "recover" bits that were never encoded.

There is no such thing as "effective bit gain." Unless you believe in dragons that fly.

I think you are confusing Protune, which is ten bits GoPro in an 8 bit wrapper, with normal 8 bit source. Encoding that as 10 bit only adds air to the container.

Its the 10 bits Cineform in an 8 bit wrapper that I was referring too.  I didnt realize that was only available with ProTune...  Thanks for the clarification.
