[HELP] encode ProRes MP4 using another H264 MP4 parameters?

[Selur]

Assuming your file was created with x264 and nobody removed the encoding settings from the SEI, mediainfo should be able to display the encoding settings.
If that is the case you can copy those settings, enter them under "x264->Misc->Imports/Addition->Command line->MediaInfo import" and press "x264->Misc->Imports/Addition->Command line->MediaInfo import->Import MediaInfo 'Encoding Settings'".
