    I found ffmpeg could do the task. To install the ffmpeg sudo apt-get install ffmpeg To copy a specific short duration from the video file.

    ffmpeg -i original.mp4 -ss 00:01:52 -c copy -t 00:00:10 output.mp4

    • -i:input file. The file name of the original video clip.
    • -ss:start timestamp. In my case I tried to copy the new video from the original video started after 1 minute and 52 seconds.

    • -t:indicating the duration of the new video clip, in my case, 10 seconds.

    • Not sure parameter -c for, maybe the action? If some1 knows, let me know plz.

  3. Avidemux is good for quickly cutting video. Despite the name, it handles MPEG-4 video standards fine (as well as any other modern format like MKV).

    It's not a non-linear editor, meaning that once you've made some cuts you can't go back and change earlier ones, and you can't re-order segments or insert new segments (although you can join videos by adding new clips at the end). It's great for simple tasks like trimming the start and end and maybe commercial breaks.

    It can do what you want without issues - just select the segment to output, export it, then select the next part, and so on. If your selections fall on GOP boundaries (ie I-frames) then you can do it losslessly - without re-encoding, using "copy" as the video/audio codecs.
