Hey everyone...I am stumped...and I dont know if its a simple fix and am thinking too much into it, or if its really hard to do...anyways here is what I am trying to achieve...

I want to take a still image and add motion to it....maybe a zoom in slowly, pan a bit and rotate a little....thats fine...piece of cake to do...but what if I want the image to start at 50% of its size (lets just say) - and then have it zoom in...but I want it to remain in the same size box it started in. Whenever I add keyframes to zoom the entire box enlarges...I just want it to stay within a smaller frame.

Does this make sense?

Thanks!

-Matt

Do you want your 'box' to be smaller than the video-frame? If so, then you need a mask. Let me know if I've understood you, and I'll gladly run you through the steps.

This is how I have done it. I would go to Photoshop and seperate the image from the background into two different layers. So let's say you are looking through a window where all you can see is the subject (which is supposed to grow larger as it comes closer to you), I would cut out what you see and make that one layer. Then Everything else would be another layer. Import both images and lay the outer image over the inner image. The outer image will stay the same as you manipulate the image in the window. You can also create masks or even try cropping your image to do the same thing. But if you are working with still images instead of video, work in an image program like Photoshop to create the layers you need, then import the images and manipulate them as needed.

Hope this makes sense and that you have Photoshop.

I was thinking more of a 4 point garbage matte, with the corners placed on the desired box's boundary.

A luma mask on a separate track would have independent alpha and keyframes to the track above.

For me, much simpler than masking, would be to add the motion to the still photo like you already are doing, then bring that sequence into a new sequence and resize it to the size you want. You can control the motion of the still picture (zoom, pan, etc) in the first sequence and then simply size or add motion to the overall frame size in the second sequence.
