Mask copying
Hi
I’m trying to put a solid with text on top into my composition. My plan was to make it sit in the middle of the frame and when a person moves past it, they go in front of the solid and text. I have animated a mask for the person so that the area of the solid that he goes in front of is no longer seen. If that makes sense.Kind of like this clip. Notice the way the characters move in front of the text boxes https://www.youtube.com/watch?v=MARqR7r-518
The problem I am having is that when I copy the mask to the text layer the position of the mask is somewhere entirely different. The animation is the same but the mask is in the wrong place. What am I doing wrong here? Any help would be massively appreciated as I don’t fancy animating another mask just for the text. Thanks a lot for reading

Thanks very much. I’m very new to this so if you could advise me on what H&V is and how I can adjust those properties I would be very grateful. Thanks again

rather than copy/paste the mask, try using the layer with the mask on it already as a track matte for the text layer.
move the layer with the mask above the text layer, with the text layer selected choose layer>track matte>alpha matte (or alpha inverted) — the track matte options are also selectable from the modes panel in the timeline.

To expand a little bit on what Dave said…
When you copy a mask from one layer and paste it to another layer, the mask will be pasted at the same coordinates on the second layer. The potentially confusing part is that these coordinates are measured relative to each layer. If your text layer is smaller than your footage layer, or if it’s shifted down and to the right (or whatever), then the pasted mask isn’t going to line up with the copied original.
That said, Kevin’s suggestion about looking into using track mattes is a good one.

Thanks for all the help. I’m just about getting my head around it all. All my aspect ratios ‘should’ be fine after double checking. Is there anyway to line up the co-ordinates of each object easily? ie. Can I adjust my text layer to sit with my solid object?
Also, thanks for the tips regarding track mattes. I will have a look into them. I had a quick play with your suggestion, Kevin, but when I applied the matte the black solid object disappeared. Can I keep that in and still have the subject go in front of the text?
Thanks again

you could either make the layer active again (by clicking the eyeball for that layer) or by using a duplicate of the layer. using a duplicate would allow you to change it’s layer order, making it active would still require it to be the layer above the text layer (that’s just how track mattes work).
