A link to what you’re talking about is always helpful 🙂
Well, since you know the basics of organizing your images on the timeline, it’s just a matter of presenting the image sequence in a manner that’s pleasing to the eye.
One method that works well for me is to use pre-matted footage of ink bleeds or other organic flows as a track mat for my image.
That way, I can blend the images together.
To do this, place your pre-matted footage above your image, then select “Track Matte” on your image layer, and set it to “Luminescence ‘name'” where “name” is the name of your footage.
This is only one way to blend images. There are many others.
