Flow transition error

I made a video that needed to be looped for a while. I used the Flow transition and while some of the transitions worked, some didn't.
First, I slowed the clip down to 10% of it's original speed. Then added the transitions.

In the video I show Flow not acting right and then I show a demo version of MotionVFX's plugin called MorphCut.

I eventually fixed it, but not 100%. In the timeline the video looked good, but after export these transitions were a little jumpy. The final version was good enough though.

I edited the link.
I hate it that YouTube changes the UI so much. I copied the link to the video manager because now when you click one of your videos it goes straight to the video manager instead of the video as the public sees it.

OK, I get the opposite. Here's MorphCut messing up, and Flow doing great.

And yes, I did test clicking the "re-analyze" button for morphcut, and it made no difference at all.

Also note that neither of us tried to render the timeline, nor export a final video, so verify what the final product would look like. So not a really conclusive finding on either part.

Both of our examples are stretching way beyond the limits of what these were meant to do, hid jump cuts in simple talking head interviews. Something I do a ton of weekly. I used to use Morphcut daily when it was released, was great. But once Apple released Flow, I use that exclusively, as I have found it, in my work, to be far superior, faster, more accurate, for what it was made for.

But pushing extremes like this is a fun exercise.

So I guess the upshot is if you have both, you may find that each has strengths in varying circumstances.

However, as a user of MorphCut since the week of its introduction, I'm not sure either product is really meant to work adequately across a cut that has this much difference between the subject position from clip to clip.

I can see how you might say that about FCPX.guru, but mine is practically the same shot with minimal difference.
I could have used a simple cross dissolve and most people may not have noticed.

The way I ended up "fixing" it was by restarting FCPX. That tends to clean up 80% of the errors I encounter.

It does make me think I should buy morph cut just in case I need to do this again.
