Hi Stig. Convert the adjustment layer to a normal solid layer by clicking on the circle icon switch which is beside the 3D switch. You’ll probably need to set the stroke effect to “on Transparent” in its Paint Style.

Hi, a simple (though manual) method:
Add a copy of the footage underneath, push it ahead 1 frame so it’s out of sync – delete the final frame, turn off sound.
On your top layer set a HOLD keyframe for Opacity 100, go to first problem frame set a hold keyframe at 0 Opacity, move ahead one frame set a hold keyframe for Opacity at 100. Select and copy the 2 keyframes and then paste them at each problem frame.
This might be quicker than setting markers etc. etc.?

Hi Elisabeth. A way to do it:
Make a new square composition (say 250×250). Double click the Ellipse Tool to create a circle – fill white, stroke pink. Keyframe the Elipse 1/Transform/Scale from 0 to say150 – so that the circle appears, grows and the composition ends up totally white.
Duplicate the square composition IN THE PROJECT PANEL and open this version of the square composition. Make the fill an alpha, so you have only the pink stroke.
In your main composition have the video you transition to above the video you transition from.
Add the white circle comp above the beginning of the transition. Go to the time when the circle just fills the square shape and then scale the circle comp so that the circle is the size you want them all to be.
Add the CC Repitile effect to the white circle comp and expand the up/down etc headings so that the screen is filled with the circles. (You may need to play with the scale of the comp to get even rows.)
Set the TrkMat of your incoming clip (the one below your white circle comp) to Luma.
Now when you play through the transition should basically happen.
Add the Stroke only composition directly above the circle comp and copy the CC Repitile effect to it.

You should have in layer order:
Stroke only composition
Circle composition
Incoming clip (with its track matte set to Luma)
Outgoing clip

Let me know if anything is unclear.

Hi. You can select all your properties as a group and press the new keyframe icon and all selected properties will be affected. Next time only one new keyframe will be created but you can again select all properties etc.

Hi. Trapcode Particular allows particles to follow paths:

Hi, wow that’s a complex job, presuming that it has to be a somewhat accurate depiction of the currents. My only thoughts would be to start with a base image of Fractal Noise (Fractal Type – Strings). Precompose it and then in your main comp keyframe the Liquify effect – mainly the Warp and Twirl tools to create the streams and whirls.

Hi Ruo. There are so many ways of doing this and they would all look different. Can you show an example or describe more completely what you want. i.e. I imagine you don’t want it to just scale from 100 to 0. Should it smear, should it twirl? Should the shrinking image have straight edges or should it be more fluid? etc.

[Greg Gesch]

Other thought, can you mask the crushing hand and reverse it so that it rises and then crushes?

Hi. The nearest thing to an “erode” could be the Roughen Edges effect, might be worth a look.
