Downloaded video has damaged length metadata

[Lassoloc]

bug description
was saving a stupid 11 second meme video, however the video downloaded states a time of 00:00. it plays normally on my phone but my media picker is unsure of what to do with it when trying to share

reproduction steps
steps to reproduce the behavior:

1. go to 'cobalt.tools'
2. unsure if relevant, but settings used were 8k quality for maximum available resolution and h264 codec.
3. download this video: [https://youtu.be/jTyClhN57Ic?si=mQy6c73nT-voMHQb]

I don't think cobalt knows how long the video is, usually running ffmpeg -i input.mp4 -c copy output.mp4 fixes it losslessly

Same thing happens on PC
