thanks Ross, that sounds li= ke a good compromise.

I will look in the tutorial as wel= l. =C2=A0from scrubbing through I see it has an ipad screen replacement wit= h real reflections
it looks proper lit (not like mine which is very dark and creates more= problems).

about the shot to give I will contact you directly= in a moment.

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 ki= nd 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=C2=A0good 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 hav= e to remove it
and no reflections.

on th= e other hand:
without green sticker -> more rotoscoping, somet= imes difficult track, but good reflections.

the way I decided doing it was with no green beca= use 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 go= t a shot with bright sun behind
and the track was very hard. a gr= een 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
