Two Videos, 1 Over the 2nd, Slightly Smaller

Post by waffleicious »

Hey guys, I have a very simple question here.

I want to play a video in an octagon screen-shape that I have built in an installation. I have a border going around the screen that is roughly 5in in width. I would like the center octagon to play whatever is selected on Layer 1 and the border to play whatever is selected on Layer 2. I don't need any overlay or anything; I just need two videos one on top of the other but slightly smaller.

I feel like this should be a very easy thing to do but I'm kicking myself because I can't seem to figure it out.

I've been creating different sizes and types of output masks with screen 1 being the smaller mask and linking itself to Layer 1 while screen 2 is masked to the edge of the border around the octagon and is linked to Layer 2. I just can't seem to find a layer/mask order that allows you to see each video distinctly separate from one another. Do I need to adjust Input Masks? What simple thing am I doing wrong here?

Pics attached for reference.

Thanks, guys!

Btw I have read a lot about creating a white shape with a black background as a picture and placing it into it's own layer and then making that layer a mask, but isn't this something I should easily be able to do in Advanced Output?

I think this should be done partly in the Composition.
That will give you a lot more flexibility.

I'd probably make a circular (octagon if you need that) mask on a slice in the advanced output, and use that with the slice transform effect on my top layer as mask. (unchecked in the advanced output)
Then have a regular slice to take all the input from the composition.

I don't have anything applied to the bottom layer, so it will show in full when the top layer is not playing, but you can make a duplicate of the mask slice, invert the mask, and use that on layer 1.
Then you can mask the surroundings in the Output transformation if you need.

Thank you for the suggestions! I now know a bit more about slice transform!

The solution was incredibly simple, though. All I needed to do was put an input mask over slice 1 that was smaller than the border input mask on slice 2.

I was trying to make masks in the output screen which is why I had the confusion. Masking on the Input screen made it work flawlessly :D
