I have a 3000 by 3000 VR video encoded in
H264, the frame rate is
30fps. Now I want to raise the frame rate to
60fps, I am using this command
ffmpeg -i input.mp4 -r 60 output.mp4
My questions are:
- Is it meaningful to raise the frame rate?
- What is the mechanism of
-r 60in the above command? Since there are only 30 frames per second in the original video, where do those additional 30 frames come from?
- Is there any better option other than the above command to 'smoothly' raise the
