Why does using Cinepak compression when remapping a QuickTime movie to a palette result in a larger file?
A QuickTime movie’s file size is largely dependent on the type of compression used. QuickTime’s supported compressors, or “codecs”, are usually optimized for thousands or millions of colors, so 8-bit movies will generally be about the same size as 24-bit movies. If you use dithering when remapping the movie frames, the dithering information will also increase the size of the file. Note: Saving an 8-bit Cinepak in any program will usually result in a degraded image, compared to the original – this is also inherent in using Cinepak for 8-bit compression. • I’m creating a multiple-frame file from different-sized images. I get an error message about the size of the images, and I’m prompted to crop or pad them. Why is this happening? When you create a movie or an animation, the images must all be the same dimensions and color depth. Because you are scaling by percent (rather than height or width), if any of the images in the list differ in size from the first, this message will appear, and
