Mask size alters with Track matte key
Hello. I'm using Premiere elements 13. I have pictures or videos as the background, say that's on Track 2. I insert a circle shape; that's on Track 3. There could be a picture or video on Track 1. I apply the Track matte key effect to the clips on Track 2 respect to the shape on Track 3 so the clips that are behind (Track 1) are seen circle shaped. But if I resize any of the clips I apply the effect to, the size and position of the shape changes as well. I want it to stay as is regardless of what I do with the clips.
Thank you
