Imagine two adjacent clips A and B with a crossfade transition. If you perform stabilization on B, the stabilization doesn't begin until the crossfade is complete. Consequently, the composited portion from B during the crossfade is unstabilized, and then suddenly, due to the zooming done by stabilization, a zoom snaps into place once the crossfade is finished.

Is there a workaround?

Edit: The workaround looks to be to stagger the cliips on different tracks (and fade out on track 1 while fading in on track 2) rather than using a crossfade on the same track. Hopefully this can be fixed. It seems obvious enough to reproduce but if you need a sample project please let me know.

Good workaround.

This looks improved in b8. Now when you stabilize a clip with a transition, it will stabilize the area of overlap.

However there is a new related bug: after stabilizing a clip, if you add a transition or expand an existing one, it makes sense that you would need to restabilize. But clicking the Stabilize button doesn't work. It looks to be a no-op (save for a progress dialog that flashes briefly). It first requires you to clear the current stabilization and then stabilize again. Ideally Resolve should detect that the clip has changed bounds and allow restabilization. (A further optimization would be to only stabilize the new areas of the clip that are now exposed, if possible.)

I'm using version 18 and this bug also happened in version 17. I don't recall it happening in version 16. The same issue of a clip not being entirely stabilized; only the portions of the clip where NO crossfade exists, will the clip stabilize. Work around as mentioned previously, is to remove the crossfades, stagger the clips on different tracks, stabilize, and then apply any crossfades.

The same bug on 20 beta3
