Sometimes when you have a really large foto and you scale it way down – it can yield less then perfect results.
Like having an image that is 3200 X 2800 and you put it in a 720X486 timeline and move on it from 12% to 22% or something like that. You can resize the image so you animate in the 80 to 100% range.
What are your sequence settings? What codec are you using?
Format of your stills?
Also, creating a move on stills in motion or AE will yield better results.
