How would I put clouds behind certain areas of my footage?

[ryanb74751266]

I have this footage and I want to make it look like the plane is actually flying in the air. There are a few windows and a windshield that I want to put a sky and clouds behind. (I have footage of the clouds).

Question is, how would I put it behind only those areas? I masked the windows out, but I'm not sure how to get the clouds to go behind only the windows.

Any help would be appreciated.

Thanks!

If your masked video is layer 2 and your clouds video is layer 1 then you will only see the clouds through the windows.

keyframe the position of the clouds to move, enable time remapping and use the LoopOut expression to loop the cloud movement. Due to masking you should perceive the loop as seamless.

Hi,

I duplicated the airplane footage and masked out everything. However, when I put the cloud layer on, this happens.

Something is probably a bit odd with how you are creating your masks. If you can't share your project file for one of us to poke through, could you at least show a bit more of what's happening with your layer's effects, masks, etc.? Make the composition panel smaller, expand the timeline panel, and expand the properties of the layers so we can see more of what's happening.

Hopefully this helps.

Here's a short video of my timeline.

Firstly apologies, late at night here. got my layers reversed

Masked airplane.mp4 should be layer 1

Clouds Layer 2

It looks layer your airplane windows are showing above the clouds eg

airplane.mp4 masked (windows only)

clouds video

airplane.mp4 unmasked

You only need the top two layers

Invert the Masks (checkboxes) and you should have airplane.mp4 without the windows

When I do that and invert the masks, the clouds are under the airplane, and isn't visible

Ryan,

Try this:

Invert the first mask ONLY

Set the remaining mask modes to Subtract

Here are two solid layers  magenta (masked) above blue -- check the mask modes and inversion settings

That worked, thanks!

When the chat bubbles are displayed near the windows, they overlap the masks like this,

Any advice on how to fix that?

[Kib]

Chat bubbles on separate layer above the masked airplane layer or are they burnt in to video?
