Vegas 15 NVENC Memory Issues

So, I crank up Vegas 15 Suite for the first time. I had just finished a very CPU intensive timelapse project of the eclipse, and I skipped out on rendering it in 4K because I haven't had a few hours to spare to do it in v14. I was hoping NVENC support in 15 would speed up the render, so I tried it.

 

First of all, here's my specs:

AMD Ryzen 7 1800x

Nvidia GTX 970 GPU

Windows 10

32mb DDR4

 

When I ran the eclipse using the new Magix AVC encoder (which does not have a 24p preset... WTF Magix?), I made a 24p preset (tried 23.976 as well) and rendered. The render seemed to SCREAM by, though it was not showing any video preview. It would have only taken about 5 minutes to reach 100%, but instead it crashes and says the system is low on memory. Memory usage ramps up until it gets to about 80%, at which point Vegas' render crashes.

 

Not the best first render attempt with this program... I thought that performance gain was too good to be true! V14 wanted several hours to do the same job (sans NVENC support).

I see what is happening now... I was using Neat Video, which was also using the GPU to accelerate, and the GPU is running out of RAM. I dropped the dynamic preview allocation to 200mb again and it started to render ok, but then Neat Video threw up a low GPU memory error which revealed the source of the issue.

Going into Neat Video's settings and changing them from 100% GPU RAM usage to 50% solved it.
