  • De l’upload à la vidéo finale [version standalone]

    31 janvier 2010, par

    Le chemin d’un document audio ou vidéo dans SPIPMotion est divisé en trois étapes distinctes.
    Upload et récupération d’informations de la vidéo source

  • ffmpeg : How to split into smaller segments & repeat last frames ?

    25 juillet 2021, par Mehmed

    I want to split the input into smaller mpeg2video mxf segments ,but I have to copy the last minutes of each segment to the first of next segment , like this :

    


    enter image description here

    


    I can split it using Segment Muxer & -segment_time 00:00:10 and know about repeat frames using loop filter , but have no any idea how combine Segment
and loop filter to repeat/copy last minutes of each segment to the next segment while splitting.

    


    I tried the following command with no success :

    


    ffmpeg -i input -vcodec mpeg2video -vf loop=loop=1:size=25:start=225 -f segment -segment_time 00:00:10 output


    


    Is it possible by a FFmpeg command ? How ?

    


  • split a video with overlap between segments

    7 mai 2023, par John Pankowicz

    I need to split a video into a sequence of segments like the following : (numbers are mm:ss) 00:00 to 03:05, 03:00 to 06:05, 06:00 to 09:05, etc. In other words, each segment will have 5 seconds of overlap with the following segment. The purpose of this is for a transcription program. Each 3 minute segment will be transcribed separately. The 5 seconds of overlap will help in stitching the transcribed text segments back together.

    



    Do I need to extract each 3 minute and 5 second segment separately ? For example, by doing the following :

    



    ffmpeg -ss 00:03:00 -i in.mp4 -t 00:06:05 -vcodec copy -acodec copy -y out.mp4


    



    Or is there a way to do all the segments in one pass ?
