This only happens with vegas videos when rednered using cpu, gpu renderer works fine.
I also tried putting the video on my phone and it works fine there. Gave it to my friend, also works fine.
And tried to reset all settings and reinstall.

I can confirm a playback issue when using DXVA2 hardware acceleration. It plays correctly with software decoding or NVIDIA CUVID.

I will investigate further.

The problem is caused by format profile set by the encoder. It is set to "Main 10@L4.1@Main". You can see this with MediaInfo. The DXVA2 decoder thinks it is a 10-bit video and uses its "Main 10" decoder, which causes wrong output, since the video is actually 8-bit.

It is something that needs to be fixed in the decoder. However the weird profile is also something that should probably be fixed in the MainConcept encoder used by Vegas.
