TV image with content panning behind it
I’ve looked at a number of masking tutorials, but I cannot find a straightforward solution to what I’m trying to accomplish (it may be because I’m not sure what keywords to use in my search).
I’m using Premiere Pro 5.5 on a W7 system. I would like to have a track (Track 2) with the picture of a TV (covering the whole visible area), and a track below (Track 1) with an image that is 4 times wider than the visible area, and that slowly pans from right to left.
I would like to take the screen area of the TV (Track 2) and make it transparent so that the content in Track 1 is visible.
This seems to be a fairly simple effect. However, when I imported the TV image as a TIFF file with a transparent TV screen, the transparency was not applied and the TV screen was opaque.
I used a Track Matte Key effect to remove the white TV screen, but that messed up other parts of the TV image.
I tried the Four Point Garbage Matte, and although that made the content in Track 1 visible, it also deleted the TV set, so I ended up with a black area instead of a TV set.
I was thinking of painting the TV screen green in PhotoShop, and try a green screen effect. But before I go on an endless trial and error process, I thought I would ask around to see what you guys would use for this kind of effect.
Alternatively, what key words would you use to describe this effect and search for a tutorial or a discussion on this?
– “partial screen transparency” ?
– “picture mask effect” ?
– Other?Thanks in advance.
