# I've noticed
while using gif movie gear that you can optimise so that repeated, non moving parts are completely removed from the animation. If you look at it frame by frame there's a lot missing. It doesn't affect the animation in any way other than file size but it's a pain should you need to turn the gif back into individual frames again.

# Yes,
tick "transparency" on the optimise palette.
Uses transparency to avoid repeating things in subsequent frames.

(from imageready help)
To optimize an animated image:

1. Choose Optimize Animation from the Animation palette menu.
2. Set the following options:
* Bounding Box to crop each frame to the area that has changed from the preceding frame. Animation files created using this option are smaller but are incompatible with GIF editors that do not support the option. (This option is selected by default and is recommended.)
* Redundant Pixel Removal to make transparent all pixels in a frame that are unchanged from the preceding frame. This option is selected by default and is recommended. The Transparency option in the Optimize palette must be selected for redundant pixel removal to work. (See Optimization options for GIF and PNG-8 formats.)

Important: Set the frame disposal method to Automatic when using the Redundant Pixel Removal option.
