  • ffmpeg : Convert any Video to padded and scaled 720p

    29 mai 2014, par capitalg

    I looked for 2 hours through the documentation, but I couldn’t figure it out.

    I currently write a script and now I need to concat up to 10 videos with different ratios/framerates/codecs/size etc.

    Currently I work with the following :

    ffmpeg.exe -i part1.mp4 -i part2.mp4 -filter_complex \
    
"[0:v]pad=width=1280:height=720:color=black[v1]; \
    
 [1:v]scale=1280:720[v2]; \
    
 [v1][0:a][v2][1:a]concat=n=2:v=1:a=1[outv][outa]" \
    
-map "[outv]" -map "[outa]" -c:v libx264 -preset ultrafast -qp 0 output.mkv

    This does attach the video but doesn’t upscale the 1st video (which is in 640x480, the 2nd video is in 720p). I can put it somewhere with x and y, but it won’t grow to the full screen.

    And as I’m already asking, here’s another question :

    ffmpeg.exe -i part1.mp4 -i part3.mp4 -i part2.mp4 -filter_complex \
    
"movie=part1.mp4, scale=1280:720 [v1] ; \
    
 amovie=part1.mp4 [a1] ; \
    
 movie=part3.mp4, pad=width=1280:height=720:x=160:y=0:color=black, scale=1280:720 [v2] ; \
    
 amovie=part2.mp4 [a2] ; \
    
 movie=part2.mp4, scale=1280:720 [v3] ; \
    
 amovie=part2.mp4 [a3] ; \
    
 [v1] [v3] [v2] concat=n=3 [outv] ; \
    
 [a1] [a3] [a2] concat=n=3:v=0:a=1 [outa]" \
    
-map "[outv]" -map "[outa]" -c:v libx264 -preset ultrafast -qp 16 output.mp4

    why does I have to write concat=n=3:v=0:a=1 [outa] but only concat=n=3 [outv]. When I also write concat=n=3 [outa] it will result in an error.

  • Как пересчитать продолжительность в метаданных видео ?

    1er juin 2020, par Ars

    After speeding up the video,

    



    ffmpeg -i in.mp4 -vf "setpts=PTS/4000" -r 120 0(4kx).mp4


    



    the video lasts a split second, but its duration in the metadata remains a few hours. Because of that ffmpeg does not process it correctly. How can I set the correct duration in the metadata of a large number of videos ?
