So I've just composited this door from Skyrim into my footage I shot, I'm wondering how I can better blend it.


http://vimeo.com/40817280

What I want to do is:

Stabilize it slightly so the movement is less dramatic.

Make the door sit on the grass properly. If anyone can give tips on accurately masking away the door that would be fab.

track some masks to the footage and use it to create a shadow between the door and the stonework frame.

Add some slight noise to the door.

Add some large pine trees or ones like the background) to the left and right of the door to make it appear tucked away in the landscape.

Add some vines / trailing plants coming down the top.

Colour correct the sky to make it look darker.

Darken the scene

Add a red glow coming from the door, the glow should slowly pulse.


Bloody hell this is a lot of steps.


There's some stuff I already know how to do, but if you have any specific techniques or general pointers, I would love to hear them. Thank you!

- Chris

Create a grass patch (from the right it seems a good option) with very fine detail for blades of grass and com at the bottom of the door.
Use Levels or whatever you like best to bring the blacks in the door at the same levels with the rest of the image.
Change initial hue in the door to match the footage and then color grade.

Thanks, I hadn't thought about the levels.

Is there a way to see the levels of both layers side by side?

Thanks.

You can lock the fx panel and look at Levels on both, but I would use the picker to sample the darkest areas and match those.

How's this look? (the door is meant to have the red glow coming from it, which I will animate to make it pulse)

I still need to make it look like sunset / nighttime, and I haven't quite worked out how to track a mask to the ground so that I can keep the grass infront of the corner of the door.

Cheers lads.

I would still cut some black - here's a quick test I did:
Pass01- used Levels to bring Gamma to 0.97 and Output Black to 8.0
Pass02 - quick Magic Bullet Looks "Grand Sunset"

As far as the grass patch- if you create a patch in PSD use the track data to comp that in front of the door.

Thanks, I already did that with the grass. It doesn't track perfectly but it's barely noticeable.

My Dissertation is on VFX, so I feel like if I use Magic Bullet it would be cheating ;) Don't worry, I already have experience with Apple Color.


Cheers!
