--Montage feature doesn't work correctly (maybe just with --fps=60?)

My expectation on the --montage flag would be to see the original untouched video on (I'm guessing the left side), but, regardless of side, both images in the video have blurry interpolation when I advance frame by frame. I would expect the original side to just repeat the same original frame to match the new FPS, and the other side to have been processed with RIFE.

I did use --fps=60 as my only other flag, and maybe my expectation on how it should work is just incorrect. There was a warning about audio being unavailable, but not montage.

This is my first look at AI anything, so I appreciate all that you've done. Your work is totally fascinating. Thank you. I'm so used to installing software and it just not working (For example, installing Cuda took 6 hours of problem solving with various workarounds required, and after all that pytorch still doesn't see it), and the unbundled nature of Python source files had me worried I would be wasting my time. Amazingly, it just worked problem free.

Start by reproducing the reported command using --montage with --fps=60, then advance through the output frame by frame to compare both sides with the expected original and RIFE-processed video. Determine whether the behavior is an implementation problem or an incorrect expectation, and consider the audio-unavailable warning separately. Done means the montage behavior is correct or its documented behavior is clarified.
