82300-qrk7nqke.mp4

Convert the MP4 file using software to enforce a constant framerate (CFR).

I can provide the exact conversion settings to fix the length.

OBS or screen recording software often creates files with variable framerates to save resources. Editing applications (like Lightworks or DaVinci Resolve) expect a constant framerate.

Did this video come from a or a smartphone?

Based on the query regarding a video file ("82300-qRK7NQkE.mp4") appearing longer than expected in editing software, this is a common issue often related to recording rather than a fixed, standard framerate .
