how to encode a ProRes file using x265 to get the same parameters? - ssdde - 08.01.2022
i want to encode a ProRes PCM file , using x265, but i also want to keep the same Video and Audio parameters below from another file after encoding, so how to set in Hybrid to get the same parameters.
note, there is no bitrate in video info, but only a bitrate in overrall bit rate, is 32.0Mb/s, i want get the same result, also want the same filesize after encoding, then Color space YUV, Chroma subsampling, 4:2:0, Bit depth 10 bits, keep the same, how to set?
and you can see there is no bitrate and size in Audio info, i want to get the same result, after encoding, get file with AAC LC, can't see bitrate and size in audio info. so how to set audio like this? thanks.

Can't be done in Hybrid. Hybrid leaves way more meta data in the file.
You would need to remux the file after using Hybrid and strip some meta data from it while doing so. (reading up about ffmpeg and its bitstream filters and how it can change the meta data of a file is probably a good starting point; mkvprobedit might also be interessting)
(No I won't try to write code to add the ability to mimic some metadata.)
What you want to do isn't about encoding with the same settings, but about minimizing the meta data.
When using x265, make sure to disable the settings in the Signaling-tab)

thank you. but if i want the encoded file is as the same as Overall bit rate 32.0 Mb/s, how to set?
and the encoded file is REC709, how to set to make it Color space YUV, thanks.

Overall bitrate is simply file size / video length.

Color Matrix signaling can be changed in the corresponding tab.
Conversion between color matrixes can be done through for example 'ColorMatrix' filter.
