ffmpeg timelapse very slow
24 septembre 2018, par LukeLRI’m using
ffmpeg -i IMG_5299.MOV -c:v libx264 -crf 20 -r 60 -filter:v "setpts=0.0015*PTS" -an IMG_5299-speedup.mkv
to create a 600x timelapse out of a H.265 4K 60fps video. I just want
ffmpeg
to pick every 600th frame and put it together to a new 60fps video. No interpolation, no nothing. Still, I only get 0.2 fps on a very recent i5-7600T CPU, while converting the same video without speedup usingffmpeg -i IMG_5299.MOV -c:v libx264 -crf 20 -an IMG_5299-2.mkv
gives me 5 fps. So why is speeding the video up 25x times slower than just converting it ? Is it doing any nifty interpolation for each frame out of 600 frames or something ?
EDIT : That’s the statusline I get after several minutes of encoding :
frame= 447 fps=0.2 q=28.0 size= 68639kB time=00:00:06.56 bitrate=85611.1kbits/s dup=0 drop=147650 speed=0.00233x

Zoom effect with ffmpeg always shows error [duplicate]
13 août 2020, par asoredHow can I create a Ken Burns slow zoom effect in a with
ffmpeg
generated video ?

I have this :


'ffmpeg -r 12 -i $tempPath/img%04d.jpg -vcodec libx264 -y -an -vf "pad=ceil(iw/2)*2:ceil(ih/2)*2" $tempPath/$videoFileName.mp4'


What I tried :


'ffmpeg -r $12 -i $tempPath/img%04d.jpg -vcodec libx264 -y -an -vf "zoompan=z=if(lte(zoom,1.0),1.5,max(1.001,zoom-0.0015)):d=125" "pad=ceil(iw/2)*2:ceil(ih/2)*2" $tempPath/$videoFileName.mp4'


But I get the error :
Unable to find a suitable output format for 'pad=ceil(iw/2)*2:ceil(ih/2)*2'


Where is the issue ?
