I am speeding up a video fps rate to 24 fps. The total # of frames must
stay the same. The audio must speed up also to keep sync.
ffmpeg -i input -r 24 -filter:v setpts=0.999*PTS output
Do I have to add these options to the audio?
-filter:a atempo=1.001
I thought just -r would be global and include the audio thus speeding it up.
I do not put in "-filter:a atempo=1.001". Am I correct?
