Screen replacement in After effects with some roto
Firstly thanks for let me asks this question. I genuinely find this site so useful.
I’ve been vfx supervising on a shoot and i will also being post where i am needed to replace a few screens on iPads , iphines, and big screen oh and mocked up touch screen table surface.
This final one with cause me most problems I fear as I have multiple hand movements over screen of table. We did place green paper under the glass on the table to see if it would help pull a key. So I have my footage which was shot on canon c300 and I need to replace various screens but the shots in which others interact with screen I may have to roto around moving fingers etc.
Think minority report on a Microsoft surface thingy
Any advice or tips would be ace! Thanks

Hi Dave,
Sorry I didn’t include more info but I hope this should be some help…
This is a quick turn around pitch film and I’ll need to comp in some shots of ‘concept UI” onto a coffee table we added a green section to. ( Photo Attached ).
I fear that in a addition to keying, I will also need to rota around the actors arm as he swipes. I am using AE CC and cutting the piece in Premiere.
Any help would be greatly appreciated.
Kind Regards
Ben Lewis

I’d key the green to get close and then roto as needed to fill in holes.
As for the reflections I’d recommend using a despill method (I still like Channel Mixer) to remove the green from the table and then Screen your interface footage in on top.
The keyed/roto’d layer would go above that.
