Question / Help Black Screen when recording with lossless

[ShiroSR]

Hey! I have a problem and I hope someone can help me solving it.
I downloaded this new OBS Studio because it's far way better than the old one (at least imo).
Today I wanted to record a very short clip of League of Legends and I realized there is a new setting for recording called LossLess.
I tried it and after recording it the file (.avi) is just a black screen, even that it size is like 3gb or something like that, I tried changing the directory to my SSD and even that I keep getting this black screen on the file.

Any help?

Thank you in advance, Shiro :P.

What media player are you trying to play it with?

 

[ShiroSR]

I tried with all windows media players. If I try to use it on Premiere it says corrupt file.

Premiere is among the worst program to try to open it with.

The lossless profile uses utvideo for the video stream. Try installing the highest version number from http://umezawa.dyndns.info/archive/utvideo/ and playing the file in MPC-HC
