Hello -- somehow I have managed to place a frame around my still images. It was cute once, but now I need to get rid of it. I hope to use a still image behind my talent using chroma key. How'd I get that thing on in the first place, and how do I get rid of it!?
Welcome to the forum.
Personally, I'd do this in Photoshop and create an Action to Batch process the removal of the "frame."
Now, in PrPro, you can apply the Crop Effect to the still image with the "frame." If they are all the same, then once applied to the first, Rt-click, choose Copy. Now, Select all others, Rt-click on them and choose Paste Attributes.
You might want to put a Colored Matte on a lower Video Track for a "background." You could also place an abstract still below.
If you still have it on a separate track, remove it. If it has been rendered into one track, you can't. If your background is a properly lit green or blue screen, you can try chroma key with Keylight in AE, if not, forget it.
