grid of images

[Mike Clasby]

I love that movie>

To create a 4×4 Grid, Alt Click the Position Stopwatch and Paste this expression on the 16 layers Position:

numRows = 4;
numCols = 4;

row = Math.floor((index – 1)/numCols);
col = (index – 1)%numCols;
x = col*width + width/2;
y = row*height + height/2;
xOffset = (this_comp.width – numCols*width)/2;
yOffset = (this_comp.height – numRows*height)/2;

[x,y,position] + [xOffset,yOffset]

Once you’ve done it to one layer, select Position, Edit >Copy Expression Only, then select the other 15 and Paste.

If you want a 3×3 grid change the numRows and numCols.

Oh, yes, you’ll probably have to scale the layers down to get them to fit, and the 16 layers must be on top of the layer stack, so to put anything ontop of you video grid, drag that comp into a new comp, then on a Black Solid Layer add the Render > Grid Effect to get your black outlines. Size from Width An Height Sliders, and make them the dimensions of your videos (or whatever the right size is). Also any text over the grid goes in this comp.

This expression is from Dan Ebbert’s tut on Noise, click his head a scroll down.

Or you could make up a grid template in Photoshop (using ‘select>grid’) and then import that PSD with guides as a composition and set ‘snap to guides’ then pull all your footage in and size each layer to fit – should be a piece of cake.
