Hi all,
I'm wanting to create a fairly simple effect. I've got a magnifying glass image that I want to use to magnify a picture under it. I'm using the CE Magnify effect. I've applied it to a large, scaled down underlying image and set the magnification level accordingly. This allowed me to magnify the image without getting the pixelated look common when resizing smaller images. I then added an expression to the position of the Magnify effect so that it would link to the position of my magnifying glass. But when I move the magnifying glass, the CE magnify center gets offset and the magnification area moves out from under the magnifying glass.
So I played with this awhile and found that the problem is my underlying image size. Since I've used a larger image, the expression is matching the coordinates of the smaller magnifying glass to the larger image and the effect gets thrown off. I tried applying the expression twice, once to the x and once to the y positions, hoping I could then set an offset factor in the expression. But that didn't work and I got a syntax error.
I then tried precomposing the background later, but when I ran the magnify effect on it, I got the pixelated look, as the CE magnify effect is magnifying the comp, and not the high-res image in the comp.
I even tried making the magnifying glass image at the same high-res size as the background image, hoping that the coordinates would match and everything would sync up. But I still got weird offsets.
Has anyone successfully done this? Is there an easy way to create this effect, or do I just need to hand keyframe it all?
Thanks in advance,
Steve
