Exporting animation to be comped in over live footage
Hello!
I’m trying to comp in an animated character over live action footage. I had worked with an artist on my last film who had done the same thing but they’re unreachable now. I have the files and they’re in SGI format. When I check them out in AE, they have a black background. They can be exported as MP$ and be comped in but when I try it on my own, it comes out as a separate video (see below). What am I doing wrong?

Can you choose to interpret the SGI format with an alpha channel in the interpret footage dialog?

I don’t have that option but even in the previous artists work, when asked, he told me “The black is nothing. No alpha. And no RGB”
I don’t know how much that helps, if at all, but it’s all the info I have to go on.

It can’t be neither alpha nor RGB though…
Anyway, you might try the Extract effect to cut out the very darkest pixels.– The Great Szalam

Yeah, I have no clue what he meant either
My current artist is doing the art in photoshop and using after effects to animate. What setting(s) should he use to make it so that the animation is able to be comped in over live action seamlessly? We’re both rather new to this so thank you for your patience 🙂

After Effects can import Photoshop files. No need to do anything fancy. 🙂

well, I mean in the sense of making it so that it can be comped in. Backgrounds etc. I’ve seen green backgrounds, blue, black, and yet on export and when I put them in premiere to edit, it comes out like a separate video like in my original post.

I would recommend compositing in After Effects.
I generally use Premiere to edit and then use After Effects to do compositing.That being said, if you really want to use Premiere to do your comping, just export from AE into a format that supports alpha and make sure you have it enabled.
For example, in your Output Module, you could choose QuickTime with the PNG codec. And then make sure you choose RGB + Alpha!

The plan is for me to shoot live action, give him a low res version so he can create and comp, export the files, and I import them into premiere for the edit/final export. On his export, use the settings in the shot you just showed me?

The RGB + Alpha is the key to get an alpha channel in your final product, yes.

So when I do the export of the SGI files (which is how the animator is exporting the animation files) to adobe media encoder, what format shall I use to put them into my timeline in premiere? As of now, I used h264 and it comes out as a separate video and when laid into the timeline, it just comes out as a video track.. What output would you suggest?
