I'm using the freehand mask to envelop my cg characters animation to later apply displacement filter, doing so at each frame, do I after each frame click the animate button to envelop that frame before going to next frame or wait until the entire animation is freehanded before clicking animate button? Also if I save project at any point can I return to last frame freehanded and resume where I left off? If so how? New at this

Draw the mask on frame 1, then click the animate tab. From here on in, you just stay in the animate tab and reposition the points for each frame, by dragging them. Once you click animate, if you switch back to the draw tab you will lose all the keyframes you have set, so you want to avoid that. Its also important, for this reason, to make sure your first frame has enough control points for every frame in the sequence, as you can't add new control points once you start animating, without losing all your keyframes.
If you save the project and want to resume your masking later, just select the mask, move the playhead to the next frame you need to work on, and commence dragging the points.

Thank you Axeman for your help. I'm at the end of this task, and not sure how this masking works frame by frame, with each frame change and adjustment to the character the red animate mask moves covering all of the characters previous animation positions. My thinking was that the filter would only cover the affected character, not the entire surrounding area. (confused) I guess i will see the ending soon enough or be back here with another question, lol. To complete this do i now go back to the first frame, click on composite, then the displacement filter (doing this turns the entire screen black) Turning off displacement turns the character black. Thanks for your help

If you're doing what I think you're doing, "adding the displacement to your video layer" try this...
Add a grade object from the effects toolset on to your timeline.
Stretch it to fill as many frames as you need or the length of your animation.
Copy the mask attributes from your video layer and paste them on to the grade object.
Now delete the mask from your video layer.
Add the Displacement map to the grade object.
Let me know if that works for you.

Hi again spydurhank, it looks like i'm into a steep learning curve with this project, I think I now have my problem not solved but the knowledge light is becoming brighter at the end of the tunnel, at least for this one project. I was attempting to go frame by frame to make a hand drawn mask, but my problem was leaving out steps that for whatever reason was not known by me. When you animate the mask you need to make the figure that's under the mask visible again for the next frame because it changes position as the character animates. This i did not know or do, so I ended up with a big red mask that stretched across many frames. Also this frame by frame is for the birds, its too tedious. Now i am back trying to figure out how to make an alpha of this character within the scene I created to import to visionlab. My past efforts ended in failure as the primary scene and the alpha scene did not sync, I'm thinking the reason for this has to do maybe with the codec they were rendered with, but don't know for sure, hoping fxhome or one of its users can lead me in the right direction.

What software are you rendering from to create the alpha? Will it not allow you to render the image and the alpha in a single video clip or image sequence; it forces you to split them? If they don't align, is it a timing thing, where you could possibly shift one clip or the other over slightly in the timeline and get them to align, or is the alpha rendering system you are using just not up to the task?
Are you trying to make the character 'go invisible' mid-scene, or what purpose, exactly, is the displacement serving?

Thanks axeman for replying, I'm, using Iclone as my movie maker. Just determined that it will allow me to make a green screen of my project solving at least part of my learning curve. So correct me if I'm wrong, I now send this green screen to visionlab (layer 2)with my background footage of my original scene (layer 1), chroma key layer 2,apply displacement and render. In orignal scene before rendering out of Iclone is there a need for me to delete the green screen character from my background scene? In answer to your last question, yes the character is supposed to go invisible mid scene

OK, so you will want a background plate with no character, then you will want a greenscreen layer with your character. Put the background on the timeline, then above it, place two layers of the greenscreen character clip. Apply a displacement map to the bottom character layer, and find the frame where you want him to start disappearing.Now at this pint, you want to fade the transparency of the top character layer, which will expose the displaced layer below it. You can also keyframe the displacement to gradually increase as well, if you wish.
If you want the invisibility to sort of 'wide' over him, rather than fading onto him all at once, then use an animated mask to gradually hide the top greenscreen layer.

Thank you much, think I got it now.
