VideoStitcher studio, cannot save output

[antithing]

Hi, and thank you for making this available!
i am on windows, CUDA 11, 64 bit.
I have my clips stitched and ready to export, but when I process, the output video does not exist. The process runs, and then completes successfully, but no video is stored.

The log is:

Ah this seems to be the same issue as:

#27 (comment)

Mp4 with h264 at more than 4k resolution. Switching to mov has my files appearing. Thanks!
