Scaling a masked overlay not possible

[jotti]

On the main track I have a Christmas tree with balls.

On an overlay track I have a face, which I want to place in the ball. What I like to do is

1. Create a mask for the face.
2. Scale the overlay and position it over the ball.

Doesn't seem to work this way. What I did was I added the overlay track with the face. The face is of course not filmed to be on right spot on the screen, nor to be of right size. So I just add the mask and edit the mask to fit the face. Then I add the transparency effect. I get a nice overlay, where only the face is seen from the overlay track. Now I want to position and scale the face to fit the ball. I add the scale effect. But it doesn't scale everything I have so far on the track. It scales only the mask, but not the video with the face. This is not what I would call a chain. And when only the mask is scaled, even the boundaries of the mask frame get scaled. So if I have a nice oval spot for the face and everything around it is transparent, it is transparent only to the corners of the frame. Scaling down drags the corners inwards, making a non transparent frame, where the overlay video gets visible, because it didn't get scaled.

So what I believe I would have to do is I'd have to first scale the overlay video, then add the mask&transparency. But that is a pain! If I need to adjust the positioning, I have to go to the scale effect, then I have to adjust the mask. Instead of just creating a masked face, then scaling and positioning it. What am I missing here?

If your intent is correctly understood, yes, create the scaled, positioned face first so that it fits the ball precisely over the entirety of the action.

Then animate the face mask to track it.  http://help.nchsoftware.com/help/en/videopad/win/effects_animating.html

Nat's solution, below, is a better approach.

Hi

This is awkward  but try it this way..

• Put clip with head on the timeline and draw a mask around the head.
• Untick Mask inside
• Add a transparency effect...Head is now outlined with transparent background. (Note Scale will not work correctly at this point.)
•  
• 
•  
• Create a Sequence. Time line will clear.
• Load balls clip to the timeline Track 1
• Load the Head Sequence to Track 2.
•  
• 
•  
• You can now Scale and Position the head to fit on the ball
