I have an animated gif and use save for web in photoshop but somehow the used frames don't disappear and are shown under the new frames. There is transparency in the gif and so you can see the old frames. When I save it with background it works fine. In photoshop only one layer is shown per frame and there are no settings left to check... how can I make the gif refresh the canvas?
On a more practical level, you might not have checked the box for Transparency (in the Save for web and devices panel). I've just tried with and without this checked and when I try without, the animation leaves a certain trail. Also you have to choose No transparency dither in the dropdown menu right below the the Transparency check box just to make sure (gifs don't have transparency blending, it's either 100% or 0%).
Also uncheck the Interlaced option just to be sure.
I found for GIMP there's two solutions depending on the version:
- by choosing from "Frame disposal where unspecified" option "One frame per layer (replace)"
- For the current version (2.8.0), in the name for each frame layer, include (replace). For example:
