You can modify parts of the animation like the number of frames it has, its colors, transparency, and speed. You can also retouch individual frames using a small paintbrush tool.
GIF Movie Gear will optimize your animations by reducing the colors present in the image, eliminating unnecessary frames, and making the parts of the animation that repeat transparent.
You can work in the program with the following formats: AVI, BMP, DIB, PSD, PNG, and JPEG. You can also use it to edit icons, cursors, and animated cursors.
