Vegas Pro 20 Render Prores 4k File size anomaly

Hi, I just rendered 100 mins of ProRes 422LT 3840x2160 4K video footage from Vegas Pro 20 timeline nested project to ProRes 422HQ. The resulting file sizes are as follows: 3840x2160 4k file is (90GB) while the 1920x1080 2k file is (125GB). Media Info app shows almost identical specs except for width and height. I'm using the Vegas ProRes HQ render templates for each file. The resultant file sizes are counterintuitive.

Is the file size anomaly something to be concerned about?

That makes more sense. You need ~2x the final render amount on your c drive

Very good troubleshooting!

You will have more than enough room if you have triple the free space available on your hard drive than the projected product size. It's for buffers, temp files, and the virtual memory demands of nonlinear editing.
