Title may not be the best... I have video I am working on that only uses still images that I move by zooming and such... My background zooms out during the video, and I would like to keep an image placed on the background (some flags for the top of arch) As the background moves my images are not moving with the background and get out of place, and ideas? I'm sure this is a simple one and I know how it is done with a video using motion tracker of course I can't use motion tracker for this one, I also know i can key frame the flags in position but anything easier would be best. Thank you!
Look up the term, "parenting".
Because your source materials are still images, it may be very easy to composite these elements in a single precomp/nested comp, then move the entire precomp as a whole.
If none of your elements move until you put position/scale animation on them, you could create the flag+castle composition in Photoshop. That might be the easiest way.
If you have already created the "zooming" animation on the background layer and want to be sure that other layers animate similarly, you can parent multiple layers to the background (animated) layer. By opening the "Parent" column and linking the child (flag layer) to the parent (background), you'll be able to edit the flag even though it follows the animation of the background.
