Is there a way to non-linear speed-up video with ffmpeg ?
3 mars 2020, par leoossaI’ve seen thousands of websites suggesting using setpts to speedup video
ffmpeg -i input.mp4 -filter:v "setpts=0.5*PTS" output.mp4
The thing is - I don’t want to speed-up video in a linear way. I want it to accelerate. So I want ’acceleration’ (Wiki) to be constant and ’speed’ to be growing.
From what I’ve seen on ffmpeg docs setpts can be an equation, I tried to play with PREV_OUTPTS but with no success.
Is it even possible to achieve that with ffmpeg ? -
Stack gifs with FFmpeg without loss of quality
28 mai 2019, par Kostiantyn LapchevskyiI have two animated gifs of the same duration and size that I am trying to stack vertically with ffmpeg :
ffmpeg input_1.gif -i input_2.gif -filter_complex vstack -q:v 1 output.gif
The problem is that resulting gif experience quite some loss of quality. Furthermore, it seems that option
-q:v
has no effect at all, regardless of supplied value and (valid) positioning within command.Does anybody know a way to overcome it ?
