Clip start position is ignored

[devklick]

I'm trying to extract a section in the middle of an mp4 file. When I set the start position, then end position, then save media, the outputted file contains everything from the start or the original clip up to the end position I specified, so it seems like the start position I set is being ignored.

I've tried with 3 different mp4 clips, all recorded with SimpleScreenRecorder.

Steps to recreate:

• Load mp4 file into Vid Cutter
• Move playhead to middle of file
• Click Start Clip
• Move playhead to somewhere to the right (so the clip runtime is around 1 second, for simplicity)
• Click End Clip
• Save Media
• Check output file, starts at original clip start, ends at specified clip end position.

I'm experiencing the same issue. When I save the file, in the "your media file is ready" window it will say the correct duration, but the actual file will still start at the start of the original file.

Same with the Flatpak version installed on a Fedora 39:
