Well there are some bugs that show up when one section is generated, the clip don't seem to fit together somehow

Nobody has claimed this yet.

This may help you find what is the error, the sectiond don't seems to be connected well together and the video can be played in vlc but other for example the davinci resolve would not understand the format

Start by reproducing section generation and reviewing the traceback through Gradio's video postprocessing, especially the ffprobe check. Compare the generated section clips and their format in VLC and DaVinci Resolve. Done means sections connect correctly and the resulting video is recognized by both players without the reported failure.
