Using ffmpeg to increase framerate without changing duration [closed]
11 février 2024, par sarunwI want to increase the video frame rate with FFmpeg.


I found from this website, https://trac.ffmpeg.org/wiki/ChangingFrameRate, that I can use
-r
orfps filter
.

The doc said the output duration of the video would stay the same, but that is not the case in my test.


What I tried so far.


I got a video with a duration of 19 seconds at 1.45 fps (I took this number from the QuickTime app)


After using these commands, fps become 30, but the duration becomes 1 second.


ffmpeg -i <input /> -filter:v fps=fps=30 <output>
ffmpeg -i <input /> -filter:v fps=30 <output>
ffmpeg -y -r 30 -i <input /> <output>
</output></output></output>
