Error "AVPro Video Render Format Unsupported"

When I try to render a video, I get the same error every time "AVPro Video Render Format Unsupported."

I've tried using the Basic Rendering Framework and I get this error, followed by SeeMusic crashing:

I should mention that I'm rendering in 1080p, 60fps, and without audio. Also, the background of the video is animated, however I get the same error when trying to render the exact video with a still background. I've tried using previous versions of SeeMusic to render the video and I get the error even still.

The error does not occur when I try to render a different video. What causes this error? I may be able to figure it out with more troubleshooting, but I figured I'd let you know it was happening.
