How to automate an effect automatically?

I'll explain my specific case, but I think the concept could be generallized.. so looking for generalizable approaches to this problem.

I have two video clips from two camera angles overlapping (full screen).. so you can only see one at a time.

I want to automatically switch between them on a given duration... e.g., depending on the tempo of a song, duration of section, etc.

For example, I could manually modify the opacity of the 'top' clip to 0% to let the lower show through, then re-set to 100% every so often.. but doing this precisely, and accurately, would be a time consuming task.

Happy to consider scriptiong or other means to make this happen.. just not familiar w/ what is possible in premiere at this point.

Thanks!

With my (paid) extension Automation Blocks for Pr you can write custom automations which also keyframe properties like opacity.

In general, Automation Blocks comes with many ready to use sample automations and you can either customize those or create new ones from scratch.

See here for examles involving keyframes:

OK... after some false leads w/ Google AI, I think I've learned that expressions don't exist in Premiere Pro, but do in After Effects...

So, I guess what I want to do is create a template in AE that lets me do this..

If you have an idea about the process, I'd love to learn. I've done some minimal exploration in AE, but that was years ago.. and it's been a while since tinkering in PP.

Any pointers/directions appreciated...

Animoplex has a playlist of expression videos you can watch here: https://www.youtube.com/playlist?list=PLvr5U5ZSt6IzHyvSL9fo0M9NRPsTvra31

However, you gonna need to learn how to create Motion Graphics Templates (MOGRTs) which can utilize AE expressions and be used in Premiere if set up properly. Be advised that the more complex a MOGRT is, the more performance will be impacted.

Thx, I figured out the expression in AE... but now I need to understand how to generalize this... e.g., I did this by brining in two videos, and toggling the opacity between 0 and 1 on a comupted basis.

Now I want to perhaps apply that logic to a layer (?) track (?) in Premiere on which the 'top' video is on.

Yeah, I vaguely diving into MOGRTs at some point, but never really found an application.. now I have, so relearning to do... any further tips to help me on the way?
