Note: This only works if all split scenes share identical codecs, resolution, and frame rate. If a split occurs on a non-keyframe, you must re-encode the problematic scene boundary (about 1 second before and after the cut). Use ffmpeg with -force_key_frames :
ffmpeg -i original_clip.mp4 -force_key_frames "00:00:00" -c:v libx264 -crf 18 -c:a copy fixed_cut.mp4 The keyword club+vxn+vol+2+2018+webdl+split+scenes+mp4+2021 is not just random text—it is a concise technical dossier. It tells us that the content comes from a series (club/vxn), is the second volume, originated in 2018 from a streaming service (WEB-DL), was later split into individual scenes, packaged as MP4s, and finally re-handled (if not re-encoded) in 2021. club+vxn+vol+2+2018+webdl+split+scenes+mp4+2021
for f in *scene*.mp4; do ffprobe -v error -show_entries format=duration -of default=noprint_wrappers=1:nokey=1 "$f" done This outputs durations. If any scene is abnormally short, the split was flawed. To recombine split scenes into one continuous MP4 without re-encoding: Note: This only works if all split scenes
