Any media you wish to do this with must have proper alpha information
. Although I mention this in the post I linked to, perhaps I should have said this in this topic as well. With out the appropriate alpha data, an object mask will not work.
Most image editors, such as Adobe Photoshop, will offer the ability to render with an alpha channel. The steps to do this depend on the image editor you are using, so at the moment, I can not tell you how to do this. I do not believe you will be able to achieve this with Windows Movie Maker, although I may be wrong about that.
Object masks will also work with green screen footage, once you have keyed it, as it will contain the appropriate information. If you do not have a program that offers alpha rendering, you could always put your text on a green back ground, then save it, import it into VisionLab, and then key it. This will allow you to then use an object mask, following the instructions provided in the post that I linked to.
If you have any more questions regarding object masks, feel free to post back here. In the mean time, FXhome offers alpha ready FXhome credit images that you can use to experiment with object masks. You can find those here
Practice makes perfect.
