I was just messing around until I came across those messages.

My Vegas Pro is version 10 with 16gb ram, and I can render those two resolutions in 30fps.

For 1440p in 60fps, the message is

"An error occured while creating the media file. The system is low on memory. You may be able to reduce memory usage by closing other applications"

For 2160p, it says

"An error occured while creating the media file. The template is invalid"

I have closed all other applications, and they still won't work.

Is it because version 10 is incapable of achieving this or can it be fixed by downloading something?

Thank you.
