I’ve been trying to do a short basic video today in Vegas Pro 17 build 452 on Windows 10 but it’s running very slowly and the rendered video is full of glitches. Up until today I've had no issues. My project properties are HD 1080-60i (1920x1080, 29.970 fps) and ’m rendering with Sony AVC/MVC Internet 1920x1080-30p, although I’ve also tried a few others but all appear the same.
There are 6 channels:
1 solid colour
1 audio Mp3
Out of frustration I’ve ended up using Vegas Movie Studio 16.0 Platinum on the same system which worked fine. As a test I opened the Vegas Movie Studio 16.0 Platinum project in Vegas Pro 17 and rendered it but this is as glitchy as the project I originally created in it.
I’ve uploaded the 2 to Youtube:
