I have numerous 50Mbps IMX50 wrapped MXF videos. Media info/media tab read the aspect ratio as 4:3. I'd like to change that to 16:9. Ideally I would not re-encode all the content because I have 1000s of hours of content to apply this to. Ideally ffmpeg would just perform the data modification to switch the aspect ratio to 16:9.
I used the command below and it changed the aspect ratio but it then made my bit video rate 200Kbps and removed 3 of my 4 audio tracks but left the audio bit rate untouched. The video and audio codec remained the same. I'd like the bit rate and number of audio tracks to remain untouched; again without re-encoding if possible.
ffmpeg -i input.mxf -vf setdar=16:9 output.mxf
I also found that I can't use the -vcodec copy and -acodec copy with the filters (-vf).
Is there a way to use the setdar parameter and retain the original audio and video codec settings?
