  • ffmpeg : How to split a video horizontally ? [on hold]

    20 septembre 2017, par Joe3549

    I would like to split a video horizontally in the middle, and keep the upper part with its original width, and consequently with half the height. How could I use the ffmpeg parameters ? (split ?, crop ?, filter_complex ?)
    Thank you.

  • What is the purpose of the split filter in FFMpeg ?

    1er juin 2024, par TheOrbitHeart

    In complex filters specifically, is there a situation where it is necessary to use the split filter, rather than use the same input multiple times ?

    


    For example, consider the following FFmpeg command :

    


    ffmpeg -i input.mp4 -filter_complex \
  "[0:v]hflip[out1]; \
   [0:v]boxblur=10[blurred]; \
   [out1][blurred]hstack[out]" \
 -map "[out]" output.mp4


    


    It seems to work perfectly fine, But I saw some tutorials consistently using "split" in situations like this, where the input is split before any other filters are applied, making me wonder if there are unintended consequences to using inputs directly like this, I tried to find filters that may alter the input or optimization issues but I found no difference. So, it begs the question, what's the purpose of "split" ? and when should I use it ?

    


  • Split a very short second video into multiple parts

    6 décembre 2020, par Nicolas Tapino

    I've been looking for a lot of softwares that can split videos into multiple parts but most of them only manage to split large videos to let's say 1 or 2 minutes for each part.

    


    What I would like to do is to actually split a few seconds video into, let's say, 10 or more parts (therefore less that one second each, but still not frames).

    


    I don't know if ffmpeg can be that precise or if there is any other solutions that exist.
