Trying to create foam in AE.

This would be quite easy to shoot. Now a days with a GoPro, a couple of cheap LED flashlights, a black mounting board and of course a glass and beer you should be able to get pretty good footage. Depending on the model of GoPro you have you can get 120 fps in 720 (Hero 3 Black) or 1080 (Hero 4 Black). That makes for some awesome slow motion that can be modified in AE for speed changes.

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.

If you have Newton these tutorials may give you some ideas for animating the beer filling the glass. I would like to see a more organic foam buildup.

A bit off, but still near the topic of creating fluids – If you take a look at this short demo ” https://www.revisionfx.com/products/reflex/gallery/ ” ( topmost one – crystal ligth ) it is stated that RE:Flex was used to warp water to appear as if it was coming off clothing.

Now, I have both re:flex and freeform pro , but still wonder how to recreate this nice effect 🙂
Anyone here in position to share some thougths, or maybe point to a tutorial that could shed some ligth to enable me to solve this challenge?
And yes – consider me a noob. But a very interested one . . . with some years together with AE

Thanks everyone,

I’ve trying to justify purchasing Newton, but I just don’t have a good enough reason… yet. I’m working on it though!

I ended up tweaking it a bit more and still using the digital version. The “real” deal would have been much easier but it wasn’t the stylized look I was going for, it would have been too real.

I appreciate your time and suggestions though!
