slow animation with large images

[infiniti]

I have some large photos (800x600) with simple fade in and out tween. It runs fine with fast computers but on slower computers it runs ridiculously slow. I've trimmed down the file size to bare minimal (they are jpgs). Is there a work around to get the animation run smoother? Anything that helps! Thanks.

alpha tweens are simply slow, unfortunately. You will most likely see a speed increase if you publish for flash player 7.

Other methods involve visual changes to avoid having to tween large photos. Consider fading blocks out in a cascading method so that fewer pixels are having their alpha effected simultaneously. Consider covering them instead of fading them out. Try changing the rate of fade, you may get one where the 'chugging' is less apparent.

Hope you can get it running smoothly ^_^ Sometimes you just have to compromise

Actually I do have a few images that do slight movements (just moving left or right). And they run even slower than the fading ones, and this is actually my primary concern. Is there a way to get around this?

btw, I am not quite sure your method of faking the alpha fade effect, I do have some crossfades (just two image fades that overlap some portion so u can see some of the next one before first one fades out), any further explanation or a sample possibly? Appreciate it.

Moving them is just about as bad : ) The more pixels that need to be recalculated/redrawn the more slowdown. I was suggesting covering it with a flat colour, some sort of shape tween possibly.

As to the alpha effect, I can whip up something some time tommorow, or find an example real quick ^_^
