Prores Export settings

[Karlo99]

Hi Guys!

I got this image sequence from an Ai-upscaler and the images is in 16bit.

Is there any way to force the ‘Prores HQ’ to export in 10 bit?
I am not so familiar with this tab. Can i just insert a line
or does i need to remove the three others?

Thanks for any advice!

Does the built-in ten-bit ProRes HQ preset not work for you?

I think the most important parameters for 10 bit are in the Other tab:

mlt_image_format=rgb
pix_fmt=yuv422p10le

Well, i dont have that group of outputs. Maybe my version is to old 22.11.25.
I will try that code!

I now have 23.09.29 and ten_bit tab

But i got higher Bits/(Pixel*Fram) on the regular HQ and lower on the ten_bit HQ
Maybe it is MPC BE that showing wrong info?

The irony is that ProRes is a minimum 10-bit. The ten_bit category is primarily to put the processing pipeline into a proper end-to-end 10-bit mode with GPU Effects turned on as explained in Shotcut - New Version 23.05. Without GPU Effects turned on this category puts the processing pipeline into an 8-bit RGB mode because that is the best the CPU-based pipeline can do, which is better than 8-bit YUV when working with high bit depth source and output.

In my opinion, at these very high bitrates the difference between them is negligible. The codec is implemented in FFmpeg/libavcodec where you can study its source code, but I cannot explain it; I did not write it. I suspect because it is given a slightly different image such as full color range 8-bit RGB vs. limited color range 8-bit YUV that is default for the CPU-based processing pipeline.
