Why am I unable to scale a 4-second 60 fps clip down to exactly 1 second ?
20 mai 2018, par joeycatoI’m currently using the setpts filter to speed up or slow down different clips and accuracy is very important to me ( context : I’m concatenating these into a final clip that needs to be perfectly in sync with a separate video.) I’ve been using this as a general approach :
setpts=(targetDuration/totalFrameCount)*N/TB" -r targetDuration/totalFrameCount
While it’s fairly accurate most of the time, I’m wondering if I can get better results. For example, if I attempt to scale a 4-second 60fps clip down to exactly 1 second, i.e. :
ffmpeg -y -i clip_4sec.avi -filter:v "setpts=(1/240)*N/TB" -r 240/1 clip_4sec_scaled_to_1sec.avi
I actually end up with a 992ms clip. Does anyone know why this happening ? From my understanding, as long as the target duration is a multiple of frame duration ( 1/60 seconds ) this shouldn’t be an issue, correct ?
Is there a better approach I can take to improve the accuracy ?
Note : FWIW I already double-checked that the input clip has an actual frame count of 240
