What is frame disposal? Which frame-disposal method should you usually use?

What file formats can you use for animations?

A simple way to create an animation is to start with a layered Photoshop file. Use the Duplicate Current Frame button in the ImageReady Animation palette to create a new frame, and then use the Layers palette to alter the position, opacity, or effects of one of the selected frames. Then, create intermediate frames between the two frames either manually, by using the Duplicate Current Frame button, or automatically, by using the Tween command.

You can instruct ImageReady to tween intermediate frames between any two adjacent frames. Tweening can change layer opacity or position between two frames, or add new layers to a sequence of frames. You cannot tween discontiguous frames.

After using the Optimize palette, choose File > Save Optimized As to optimize animations. Choose Optimize Animation from the Animation palette menu to perform optimization tasks specific to animation files, including removing redundant pixels and cropping frames according to the bounding box.

A frame-disposal method specifies whether to discard the selected frame before displaying the next frame when an animation includes background transparency. This option determines whether the selected frame will appear through the transparent areas of the next frame. Generally, the Automatic option is suitable for most animations.

Files for animations must be saved in GIF format or as QuickTime movies. You cannot create animations as JPEG or PNG files.
