I hope this makes sense
We doing a new campaign at work and I wish to have looped footage of a flag within a body of text.
The idea is to have a plain black or white backdrop, the company name large enough so that you can see that there is footage of a flag within but not just have a flag layer with the text over the top.
I'm using AE CS6.
Easy: compose your text over the flag layer so you get an idea about the weight of the typeface (bold & ex. bold are best), how big to make it , etc. Then go to the flag layer and select Alpha Matte: it will now use the layer above it -- the text layer -- as a Track Matte. Now parent the text layer to the flag layer: when you move/scale the flag layer, the invisible text layer used as the track matte follows along.
Perfect, thanks Dave and Szalam...
