I have a video from a GoPro Hero8. It was recorded at 29.97 fps. I would
like to speed up this video. I figure it would be nice to simply increase
the frame rate to 60 fps, so a x2.002 speed-up.
Can this be done without re-encoding the video? I tried:
ffmpeg -r 60 -i in.mp4 -c:v copy -c:a copy out.mp4
This gave me output that was slightly (1MB, 0.1%) smaller, but the same
length in time.
