I have a video shot of a boxing ring and I want to put the fire IN the ring instead of it looking like it is in FRONT of the ring..I have other effects I want IN the ring but if somebody has an idea how to do one effect I would imagine I could use it to do the others.

Please advise and thank you.

Pages 58 and 59 of the reference manual cover masking. Give those a read.

OK, maybe this'll help... First add the effect to the boxing ring. Like this:

Then you make a mask around that which is supposed to be ontop of the effect like this:

Finished result:


This was of course a rough mask, but if you do it detailed it should look nice! wink Good luck!

Is masking supposed to be done frame by frame? I don't know how to do it frame by frame so I have characters moving and the mask won't follow them and the effect ends up looking stupid... help?

just make the mask on the first frame you want it and click animate. then you go to the next frame and drag the points to where they should be.

you can skip some frames if you want. then effectslab will tween the two differnet keyframes. this means that the ones you skipped will be filled in. however, its not so accurate to do it that way. I suggest skipping every 10 frames, and then going back to fix the ones that dont look good.

remember, the manual has a lot of good information in it.
