  • Crop individual frames of a video and then concat for output

    27 juin 2024, par Ashish Padave

    I want to Crop individual frames of a video and then concat for output. This works with 2 ffmpeg commands. The first one extracts each frame and the second concats them.
I want to get it done without the intermediate frames.

    


    Tried with the following

    


    ffmpeg  -y -i input.mp4 -filter_complex "[0:v]split=890[v0][v1][v2][v3][v4][v5];[v0]select='eq(n\,0)',setpts=PTS-STARTPTS,crop=404:720:225:0[v0]; [v1]select='eq(n\,1)',setpts=PTS-STARTPTS,crop=404:720:225:0[v1]; [v2]select='eq(n\,2)',setpts=PTS-STARTPTS,crop=404:720:225:0[v2]; [v3]select='eq(n\,3)',setpts=PTS-STARTPTS,crop=404:720:225:0[v3]; [v4]select='eq(n\,4)',setpts=PTS-STARTPTS,crop=404:720:225:0[v4]; [v5]select='eq(n\,5)',setpts=PTS-STARTPTS,crop=404:720:225:0[v5];[v0][v1][v2][v3][v4][v5]concat=n=6:v=1:a=0[outv]" -map "[outv]" -map 0:a? -c:a copy -vsync 2 output.mp4


    


    The above is an abridged version of the command. The video I am working with has 890 frames and a frame rate of 25.

    


    The output log with 890 frames is

    So it is basically dropping 887 frames. The output file has the full audio but no video.
Is this even possible ?

    


  • Converting avi to mp4 (use ffmpeg library) is very slow [closed]

    7 décembre 2012, par yAnTar

    I have task - convert any video from user to mp4 format.
    I use command

    ffmpeg -i $file -vcodec libx264 -vpre ultrafast -bt 500k -acodec libfaac -ab 56k -ac 2 -s 480x320 $outputFileMp4

    I try to change options bitrate, dimensions, but spped of converting is slow - 3 mbytes convert arround 90 seconds.

    If i convert avi to flv - no problem.
