    Are there any good tutorials on masking object to give that effect that it grows on the screen. For instance the Puma Spot done by Nailgun ( where fleurons and other objects grow/appear.

    I havn’t seen any tuts for that kinda effect. It’s a lot of work to get the flow of something like that, anyways I hope I’m watching the same spot as you .. it was “charcoal – Quicktime”. If I get time, I could do up a fake project for you to look at. It’s not tricky, it’s just nice design and curve’s work the best with this kinda thing.

    Anyways, hope someone else can come up with something.

    Thanks! Not too many good tuts out there for that sorta thing. I thought maybe there was a more efficient way on doing the whole effect.

    Well, I watch through it and it’s all done by hand it looks like. Some artist has done a nice charcoal stencil of the whole thing and they have put a lot of mask work in it. Truth is, you really don’t want an easy way to do this, you want control because they have married camera movment with mask moves and so on and it makes the whole thing dynamic. They can control it all, but with that comes a lot of work .. Most of the time, things that you see like this are done by hand (that’s most of the art of it) .. but that’s why I do it, I love that kinda stuff .. but heck, I’m a geek .. LOL. Would me doing up a mock project help out at all? Because I could show you some basic moves if your intrested?

    Mos Definitely, that is if you have the time to do a quick mock up. Thanks!

    Some notes about it are:

    1. Some of the more vine like thin curves can be built in Illustrator. Add each “vine” to it’s own layer. Bring in the illustrator file into AE so the layers are still respected. Then use each vine stroke as it’s own mask. Assign the “Stroke” filter to it and give it a thick setting to use as it’s own alpha. Then just animate the Stroke end point. So in effect, a thicker version of the line unerases itself looking like it’s being drawn.

    2. I’ve looked at some of these effects frame by frame and think that the artist actually uses a brush stroke frame by frame to unerase parts here and there till he builds up a really organic looking animation.

    In regards to using the layer as its own mask, would I need to create a mask within that same layer. And would I set the paint style in the stroke effects panel to reveal original Image? Thanks!
