Please help, Vegas Pro 15 black video preview and render

Evan-G wrote on 4/9/2022, 5:20 PM

Hello,
I have had this issue for months now and support has been entirely unhelpful. I do not know what caused this, but after years of use my my vegas pro 15 (build 416) video preview window is entirely black even when I change the default preview background. When I render anything out of vegas the resulting video is also completely black. The audio seems unaffected. I have tried all kinds of troubleshooting steps including multiple clean uninstalls and reinstalls.
Is there anything I can do to fix this?
Thanks

I had the exact same thing happen in V19.550 even though V18 was fine. Without my approval, Windows 10 updated my GPU driver. The next time I loaded Vegas my V19 preview Window & renders were black. I upgraded my AMD VEGA GPU drivers to one recommended by V19, and all is good now. Still not sure why V18 was fine with the Windows-provided driver and V19 was not...

It turns out that for the first time in 2 years my graphics card software became outdated and they released an update, my vegas works perfectly after getting this update. Thank you very much for your help!
