Setting very fast movie speed
24 avril 2018, par JoeSkurczysynHe tries to set the movie’s acceleration to 70 minutes so that a movie with a maximum length of 2 minutes will come out. However, FFMPEG fails. Films with a length of over 20 minutes come out, which is not what they expect.
I write this :
ffmpeg -i output.mp4 -filter:v "setpts=0.90*PTS" -an output2.mp4
What am I doing wrong ?
