  1. Hello there.

    I have 10 high-resolution videos (h264) and i'd like to cut some parts outta them and also 'merge' them all in a single 15hrs file... It's okay to cut only at keyframes, i've tried avidemux but the output is choppy, like the framerate varies continuously from 10 to 90fps. (EDIT: forgot to mention that avidemux doesn't 'crop' the audio also')

    Is there any other program (with GUI please) that allows me to do that?

    Thank you in advance.

    Before I can give you any hint , Are all videos having the same specs ? as in framerate , resolution, video/audio codec video/audio bitrate??
    And, did you already demux all the audio video streams from the containers?

    Placebo, yes the videos see identical. No idea what is demux.

    Demux

    Demuxing / demultiplexing basically means, when speaking of video formats, splitting the file that contains both audio and video data (and possible other data streams as well, like subtitles), into separate files, each containing one element of the original file.

    Demuxing file doesn't weaken the video or audio quality, it doesn't do anything for these data streams, it just simply saves them into separate files.

    Opposite of demux is muxing, which basically joins the datastreams back together.
