I'm trying to use a video file. Vegas shows his property, I can put it into the timeline, but in the preview window, I see only a black screen. When I render it, the result is the same - black frames.
I'm using the Trial version Vegas Pro 20.0 on Windows 11(64-bit) as Virtual Machine in VirtualBox. I have the same issue also in Sony Vegas Pro 12 on Windows 10.
The video was created on Ubuntu as screencast by the Kazam application:
