This is an extremely frustrating problem. I have 2 versions of Vegas Pro on my PC, one of which I didn't get the normal route (Vegas Pro 21) and one that I just recently purchased (Vegas Pro 19.) 21.0 renders videos LITERALLY 100x faster than 19.0. I have used IDENTICAL settings as well as the same test source video to render into a 10 minute video.
No matter what I do, my "borrowed" copy of 21.0 renders waaay faster than my purchased copy of 19.0. I am dumbfounded, I have made sure all the settings are identical and are using my GPU. I thought purchasing the software would lead to MORE stability. Any ideas? I will post my specs below.
Windows 11
AMD 7700x
RTX 4070 ti
32GB ram
Samsung Pro 980 SSD
