Never heard of it. Have you watched this video? It may answer your question - not sure, though.
Oh, sure, now someone shows up after I complain! 😛
Yes, I have watched that video and this video led to more questions...
So here is what I am trying to figure out...
A few weeks ago I was at a small rodeo, and it was night time, and there weren't many lights, and I was trying to track the cowboys and the poor little steers they were pursuing.
This was using my iPhone 11 Pro Max and the built-in Camera app.
I had a few problems...
1.) I needed to keep proper exposure on a particular cowboy.
One moment he was at the edge of the arena where it was dark, and the next moment he was riding by me under a bright light.
2.) I needed to keep proper focus on a particular cowboy.
One moment he was on the far edge of the dark arena, and the next he was right in my face chasing a steer.
3.) I wanted a way to smoothly zoom in and out as I tracked the cowboy.
In the link I posted above, and the one you posted, I get how the Filmic Pro exposure and focus reticles work in those basic scenarios, but how would I apply them to my situation above?
For instance...
If I put the Filmic Pro exposure reticle on the cowboy where he was located at the dark, far-end of the arena (e.g. top-left), then that would properly expose for him at that point in time.
But as soon as he changes positions and rides towards me and he appears in the lower right-hand corner of my display, then I assume that exposure reticle will no longer apply, right?
I assume that I need the exposure reticle and the focus reticle to follow my moving subject.
I guess you could place both ot them in the center of the screen, and as you track the subject they would adjust, but I'm not sure.
To be honest, my rodeo shoot seems like a godo example of where an iPhone is no competition for a true video camera, but who knows?!
That is what I need help with, because the Camera app fails miserably in such light/dark and moving subject situations, and I'm not sure that Filmic Pro is much better.
This is a question for a seasoned camera person and an expert videograher...
