Render Stuttering on Vegas Pro 20 Windows 11

I'd like to know what's going on in this scenario.

When I render, I use AVC/AAC MP4 because that's what I've always gone with.

My presets are as follows:

My Editing settings:

My Video settings:

My Project settings:

This is the result when I render a video where the only thing I did was change the songs:

After about 5-10 minutes the video render slows down to a halt and proceeds to render instantly 5 frames every pause.

Then it just proceeds to keep going, not only has this made it so that my render takes over 3 HOURS on end with a 40 minute long video where it should be taking not even 25 minutes with my current setup, but the performance just worsens as time goes on. I need a fix for this because this is just irritating me especially with my system specs.

I've updated everything, drivers, windows, and my graphics card with NVIDIA's latest studio drivers.

Just an additional thing here now that I think about it, does upscaling from a 1080p video by rendering it at 1440p causes this issue?

Regardless of this, even at 1080p the average speed of the video starts going down after a while into it and proceeds to start doing the whole stuttery mess.

Do the render benchmarks in my signature work normally? If so it's something with the project.

Also dynamic ram preview should not be set to 0 and 32 bit full is inherently slow (if the source footage isn't 10 bit don't bother with it).

Isn't 32-bit better in terms of color? I'm using an IPS display so color of a video is quite important for me for its quality.

I can try setting it to 8-bit afterward and see how it affects the performance.

OKAY YEAH... By changing from 32-bit full to 8-bit full it literally made it so that it renders 4x faster. Basically it went from 30 fps to 100+ fps on the average.

Thank you.

If you open Project Properties from the File menu and then click on the '?' in the header of the Project Properties window, the user manual will open at the Project Properties topic. There is a section giving a run down of the various pixel format settings and some tips about when to use 8 or 32 bit video processing.

Sorry I'm not a fan of reading ^^''

Probably the only subject I failed at school the most to be fair haha, that's why I usually just look for a fast answer.

I have calibrated IPS displays and take care with color correction. My footage is 8 bit and I don't use ACES in Vegas so I edit in 8 bit full and it looks good. I have dynamic ram preview at 10 percent.

If I were using 10 bit log footage I would use 32 bit full mode with view transform off and compositing gamma 2.2.

32 bit projects are only better if your video source is ten bits or higher.

With 8 bit source, you are increasing your render times in a 32 bit project, adding shadow noise, and increasing the risk of level and gamma errors.
