Thanks Ted. I thought about shooting it for real since it would be much easier, however in this case I want it to be a bit more stylized. The final effect will actually be a letter of text (black text on black bg) that gets filled with beer to reveal the text. I figured it would be easier to go for a “glass” of beer first, then use the text as an alpha track matte.
In any case, I figured out how to use a track matte to contain the bubbles which I just moved up as the beer filled it up. Here’s my first attempt which is more or less the general effect I was going for. It’s not perfect but I think it gets me a good base to start playing around with.
beer text
If at the end of the day I need to shoot real beer I’ll at least know now how to use the foam effect… which I’ve never touched before.
Thanks again Ted. Any other suggestions are more than welcome though.
