What HandBrakeCLI settings should I use to convert Apple Pro Res 422 format MOV files to a lossless format and use as input files for editing under Windows. Perhaps an AVI file. I have tried ffmpeg but this tool seems to be a non-starter.
I have had some old 8mm (silent) home movies converted to Apple Pro Res 422 format (MOV files). I use VideoStudio 2018 but these are not supported. I used ffmpeg under Ubuntu to convert them to MP4 but they were faded and washed out. I did the same with Handbrake and they played fine in VideoStudio. However, I would like to use an intermediary lossless format with VideoStudio as the input file and then edit and render as an MP4 file. Every conversion I have tried so far has resulted in a file size of between 2 and 10% (MOV file is 5.2GB converted AVI was 85MB to 300MB), so I am concerned that there is some quality loss. I accept that this will happen when I produce final MP4 files or whatever other output format I choose to use, but I would like the source files to be of higher quality like the Pro Res 422 MOV file.
