VLC not finding video after screen recording

[Liz81]

Hi,

I was trying to record my activity that I do on my PC. So I do that then when I watch it back, it says, "VLC can't recognize the input's format:
The format of 'file:///C:/Users/"username"/Desktop/test.mp4' cannot be detected. Have a look at the log for details."

Here's what the log looks like:

I recorded for more than a minute and the file was only 203 bytes. I don't know if that means anything.

Thanks!
