thanks Teddy.

do you have a screenshot of those replace markers? are those just plain stickers you cut yourself?

if I had those I would have to painstakingly remove those right? they would have interfered with the reflection...

I'd say I'm intermediate level at mocha maybe a bit more.

this shot I am talking about involved a lot of shear and sun directly at the camera

was very difficult especially during the shearing. had to manually track it in mocha

and also in AE with RG corner pin offsets.

used rotobrush for the hands which worked amazing considering it was difficult because the thumb just hangs still but slightly moves all the time.

here are the results:

here is the before:

shot#1

direct sun made track difficult

also didnt have the actual screen borders visible for reference and had to manually adjust it by eyes.

shot#2

was easier to track and still didnt have to screen borders and had to manually place them at times

to make sure I was referencing the actual screen.

what do you think was the optimal way for preparing?

We use small tracking target stickers at each corner of the screen and mocha takes care of the rest. How experienced are you with mocha? Even the most difficult tracks can be accomplished manually but there are a lot of ways to do it you may not know about. There are some great advanced tuts online even pros could learn from.

We never use green because as you said it blocks reflections, but more importantly you can get green spill on the actors that is harder to manage.

Hey y'all

I recently tracked different kind of Iphone and Ipads screen replacements
with different methods, and cant be sure whats the optimal way of preparing the shoot.

my question is:
do you use green on iphone and ipads where good reflections are needed to sell the shot?

my considerations are:
on one hand:

with green sticker -> better track and maybe easier roto, but you do have to remove it
and no reflections.

on the other hand:
without green sticker -> more rotoscoping, sometimes difficult track, but good reflections.

the way I decided doing it was with no green because mocha can track just with
the shapes and proportions and the green I get usually its just a pain to remove
and although helps me with the track, I do have to remove it and replace it. and

usually it doesn't help me with keying it because the shot is lit for the main action
and not the green inside. the problem is I got a shot with bright sun behind
and the track was very hard. a green would have at least help with the shear shift.

what do you recommend as the best course of action for iphones and ipads
and GUI screens in general (where you need the reflections)?

thanks
