Incorrect length reading on project.mp4 linux

[5cw]

Describe the bug
When I export a video on my linux mint desktop using the ffmpeg exporter, vlc (and my other installed media players) recognize it as having a much longer length than the video actually is, and it stops at the correct time but before the playback head has reached the end of the line.

To Reproduce
export a video using the ffmpeg exporter, maybe operating system has something to do with it? I also have audio on the video which has a negative start value and exceeds the end of the graphics, but the video doesn't keep rendering with the remainder of the audio and the length doesn't match so i'm unsure if that is relevant.

Expected behavior
I expect the video file to have the correct length listed and to finish along with the playback head.

Console errors
If applicable, add a screenshot of the errors displayed in the console of your browser (F12) or your terminal.

Package versions:

unsure which version of the package i'm using, happy to provide if someone shows me how to find htis
