Jumping ahead of myself is right.
I put a sample clip of the video here:
https://youtu.be/SP96aoMf1yg
In the first few seconds, the shoe was moving but after that, it is stationery relative to the floor.
The reason I wanted to use a photoshop layer was because I saw that in a tutorial, and I did not realize the clone stamp in AE can change the cloned content with time. After watching more tutorials, and after trying the photoshop layer solution, it is obvious using the clone stamp in AE is the better solution.
The tricky part, I found, is that the floor reflects the bright constume, so any static patch would stand out when it should reflect a costume but doesn’t.
so here’s my updated plan:
(1) duplicate the video and flip it upside down
(2) blur the video and lower the brightness/contrast to simulate a reflection
(3) track the “horizon” y-axis on the source clip and make the horizon in the reflected clip follow
(4) clone and paint over the shoe using the reflected video
(5) track the shoe so the cloned blob can follow the shoe as the camera pans and zooms
That’s the theory. I’m still struggling to execute each step. If it looks like it won’t work, or if there’s a simpler solution, please let me know.
I’ve looked at a mocha tutorial but hope I can do without it. Thanks for the links, I will look at them.
