Where a Transparency Optimization will generally This is particularly true of an raw video sequence These are reasonably safe optimization steps that can be applied to mostĪnimation sequences, however there is no guarantee, that it will result inĪ smaller GIF animation.

and Transparency OptimizationAt which point you can immediately save the GIF animation.

Will discuss in detail below, to attempt to optimize a GIF animation in aĬurrently this option is equivalent to (in order). ' Optimize' will use a number of the techniques, that we General Purpose GIF Optimizer of ImageMagick Or you may loose the operators effect on the final GIF file save. Global Color Table has to be done as a the last step before saving to GIF Probably the hardest aspect of optimization that users have trouble with isĬolor Optimizations caused by the color limitations That however is not the order we will look at these optimization techniques.įor GIF animations Frame Optimization is the mostīasic optimization technique, and where the most gains can be made.

When optimizing animation you should try to optimize them in the following The ability to use smaller 'sub-frame' overlays from one frame to the next. Restrictions, as well as a choice of different frame disposal techniques, and Optimizing an animation is not easy, especially a GIF animation that has color Where smaller sub-frame overlays can be used, as well as three types ofĭisposal methods controlling how an animation is handled. This is especially important for complex GIF animations
