yours looks pretty good to me. How would you want to improve it?

It still feels like a crossfade to me rather than continuous drips. But perhaps that is just because I know where to look. The two endpoints of the drip effect are below. Ideally these would drip/morph into one another without going to pure blackout. SA Morph just looks like a crossfade or if I get clever with the beziers just looks weird. Nice effect but not what I'm going for.

If I do go this route for the project there will be a *lot* of images and am looking for a solution that would mitigate processing and thus my time. A single PASeq vs. two runs of a Paseq and compositing time would be ideal.

You could use layers and have one drip away revealing the other in the previous layer.

...

Another approach is to crossfade 2 movies, where the movie is a noise modulated warp. The starting movie is no warp modulation and then the warp modulation increases over time. The ending movie has max warp modulation at frame 0 and no warp modulation for the last frame.

You don't have to use movies and content context action steps to tie them to 2 layers. you could do the modulated warps live in the keyframed PASeq timeline.

This is an interesting variation on a normal crossfade transition.

And you could use other keyframed effects that get progressive more and less extreme as the crossfade progresses.

I'd like to try that. Is there a tip blog to read about the warps?

The intent is to specifically have the transition look "painterly" in some way which is why the morph transition did not work for me. Perhaps even keyframing geodesic recursive growth over time could work

Also, this is a basic question but I could not find which parameter to use to change the direction of the water drips. My lowtech solution was to rotate the second image 180, PASeq it and then reRotate when compositing the two.

The automatic generated paths created by the paint synthesizer are based on the output of the Path Angle control panel. The drip paints are probably using a fixed path angle with a 90 degree angle offset. Changing the angle offset would change the direction of the drip.

Here's a collection of effects blog posts on warps.

There is a video tutorial on interactive warping and adjust modes available here.

You can use bezier path interpolation to build dynamic animations of individual paint strokes from one painted image to another. This is covered in the encapsulated bezier path tips (here, here). So that would be another way to build a painterly transition. You could have the paint stroke animation use wet paint strokes that overdraw on top of the previous frame output (as opposed to erasing each frame to white before painting the animating paint strokes) if you want something that appears more like overpainting as opposed to just moving paint stokes.

Awesome! Thanks. You rock as per usual.
