I have a 3.4 meg animated gif. I was only able to reduce it to 1.8 megs. Any solution, without reducing colors to shrink the animated gif to under 300K preferable ?
Most folks use a video format for a significantly large/long animation.
How big is the image (horizontal pixels x vertical pixels)?
How many frames?
Is it made up of a lot of color complexity?
That's moderately small, but with a large frame count. I'm guessing there must be a fair bit of change between frames in order to get it up to the size you've reported. GIF compression works best when exactly identical RGB values are maintained across large spaces in the image, and from frame to frame.
Beyond possibly reducing the width and height if possible, I can only suggest fooling with the color table size and other parameters available to you in the Save for Web & Devices dialog and looking critically at the results.
I've done what you suggested and only got the file size down to about 1.8-1.6 megs a far cry from under 200K.
What about 3rd party converters, do you know any you can suggest being the vast amount on the net?
