Cobalt issue or VEGAS issue? I've tried other downloaders and the video output seems to work fine in VEGAS, but not with Cobalt.

**bug description**
VEGAS Pro reads any YouTube videos I download in Cobalt at an extremely high frame rate which makes it so that I can't edit the video.
**reproduction steps**
steps to reproduce the behavior:
1. go to cobalt.tools
2. click on the URL bar and paste the video link
3. download this video: https://www.youtube.com/watch?v=x-ENzR_bD6M
4. open VEGAS Pro
5. import video

The downloaded webm video is missing the duration in it's metadata so media player will not be able to calculate the time duration, my current solution was just do stream copy locally with ffmpeg or something, with Linux we can quickly fixed this problem by running these simple command:
ffmpeg -i video.webm -c copy fixed-video.webm
I'm not sure why cobalt not post-processing downloaded video yet.

Is your downloaded video are in **webm** format?

vegas, just like all outdated software, can't calculate file length based on actual media data. this is why it gets confused.
this can be fixed by:
using newer software
ffmpeg -i filehere.mp4 -c copy outfilehere.mp4

VEGAS doesn't support webm so I use mp4 format.
