Failed to export (parser not found)

[GameHound]

I’ve recently started using shotcut from windows movie maker for YT. Then i recorded a gameplay and edited it. And when i tried to export (Youtube preset) it goes to like 45-55% and fails.

I’ve tried it multiple times and changed settings (scan mode etc.) nothing seems to work and i also tried resetting the export settings.
PLS HELP ME

Shotcut and GForce Experience/Fraps

Hi there, recently I’m using Shotcut, coming from MS MovieMaker and it needed not much time to get comfortable with it. The issue: Until recently I used Fraps to capture videos from my flight sim, these files are AVI and have ca. 5 GB each minute, not so suitable for my last partition with ca. 80 GB free disk space. So, one solution was a 1 TB SSD, another GForce Experience, With GForce Exp. I need maybe 550 MB each minute (less or more, you can adjust it), “but” GForce Exp. makes hardware …

I actually downloaded and installed Fraps. There is very little control over your settings. The software appears to be severely outdated as they can’t even update their copyright dates from years ago. Try using OBS, it’s far superior.
