Flowframes Help Needed: Frames interpolated out of sequence

[srosenow98]

Hi, all.

A while back, I had some great success after being suggested I use Flowframes for a personal project of mine involving a famous sequence of photos taken by Gary Rosenquist, of the Mount St. Helens eruption in 1980. This project involved the use of AI-enhanced documentary screenshots of that sequence. (A link to that is here: https://www.youtube.com/watch?v=UNlP9TGZOMI )

The quality of those AI-enhanced screenshots, while great for the purpose of a basic illustration, did not match the original resolution of the photos Rosenquist took. At the time, I did not have them, and that was two months ago.

Since then, through several sources (mostly old, archived USGS reports and a few books), I've been able to source the original resolution copies of Rosenquist's famous sequence, and as a result, I'm attempting a full-HD scale interpolation in the way I did the last one.

When I attempt this process, the frames are subsequently mis-ordered and interpolated out of sequence. Attached is a screenshot of the raw source folder from which I am working (disregard the last frame, it's a hypothetical frame based on a photo by another observer named Keith Ronnholm, who was at the same location, taken after Rosenquist ran out of film). Each frame is ordered 1-22.

Subsequently, I've attached a screenshot showing the output interpolation folder. Notice both the out-of-order interpolation at which the frames are created, and the garbled appearance of some of the interpolated frames. I did not experience this when performing the earlier interpolation and in fact the earlier interpolation went off without a hitch. Now that I am working with higher-resolution source material, it seems as though the interpolation is flawed. Is this because of the higher-resolution source material?

More importantly, how do I fix it?
