  Image Sequence of Different Sizes Help

  Posted by David Michael on September 12, 2009 at 4:51 pm

  Hey there, I’ve got a bunch of image sequences I’m trying to work with in AE and I can import them fine and they play well except that the images are not of uniform size. Whenever the sequence runs across an image that is smaller than the largest image it adds white space to the bottom and right side. I used a color key to try and key out the empty space, but now it is black. Does anyone know how I can make this space transparent? I appreciate any advice! Thanks.

  Thanks for your advice. If I understand you correctly, you think it would be best to keyframe each change in image size? The only problem with this is that the picture size changes from frame to frame and there are about 250 frames. And this isn’t the only image sequence I’m working with in this fashion, so putting in the time to manually do it wouldn’t make sense in the long run. If I am not understanding you properly, I apologize. Again, I appreciate your help.

  What I am thinking is that maybe if I can apply a key just to a certain region of the image (that being the black space set by the smallest image) I could do an OK job. I just hope there is a better way. Perhaps there is a better way of creating an image sequence to begin with?
