' Optimize' operator should produce a good well optimized However for most GIF animations, involving cartoon like images, the Result in a worsening of the LZW compression ratio. 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 These examples start to make use of the BasicĪnimation Handling, to try to optimize the final display and file size Ordered Dithered LZW Optimization Minor Optimizations Other Sources of Information on GIF Optimization.Dithering Colors Compression Optimization.Speed Animation - an animation with too many colors.Frame Optimization Results and Summary Semi-Transparency Handling Color Optimization.Moving Hole Animation - a difficult to frame optimize animation.No Pixel Overlay - repeated image every second frame.If you want to manually enter different delays for specific frames or remove some frames altogether, you can do it in our GIF maker - split the image and click the 'Edit animation' button.Index ImageMagick Examples Preface and Index Introduction to Optimization General Purpose GIF Optimizer of ImageMagick Frame Optimization These are technically valid values but probably shouldn't be used.

Warning: some browsers and image viewers (including Chrome) may ignore values smaller than 2 hundredths of a second, so if you enter 0 or 1, the animation will default to a slower speed when viewed in such programs. If some frames in the original animation are displayed longer than others, this option will overwrite it and may distort the flow of the animation. Slowing down a GIF too much may cause it to lose smoothness.Īlternatively, you can specify precise delay time in one-hundredths (1/100) of a second between frames a longer delay equals slower animation. If you want to change animation speed proportionally to the current animation, use '% of current speed' from the drop down.Įntering 200% will make animation run 2x faster, 50% will cause it to slow down 2x. This is a tool for adjusting GIF animation speed, thus making it run faster or slower - correct wrong speed, make a slow motion GIF, speed up slow GIFs. Change the speed of GIF (WebP, MNG) animation
