How do I save an edited gif?

The file has been optimised so that each frame only contains the changes over the last frame, as opposed to all information in every frame.

There are a couple of things you can do.

1. If you need a full frame by frame editable copy you can use an older version of Photoshop and a workaround. This works in CS6 but does not work in CC2015.5 or CC2017 (I don't have earlier CC versions installed to test)

In CS6

Go to File _ Import -Video Frames to Layers

In the dialogue enter *gif* in the File Name and set File type to Video  then click on Open

Your gif video file will appear and you can click on it

In the dialogue that opens ensure "Range to Import" is set to "From Beginning to End" and "Make Frame Animation" is checked

Press OK

Your file will open as a traditional frame by frame animation and will play and can be edited as normal

2. If you are just after stills from the video (to be saved e.g. as jpeg still images)

Open in CC.

Go to the layers panel.

Use the eye symbol to turn on the frame you need and also turn on every layer below that frame.

So if you want frame 14 as a still - the layers panel looks like this :

You can then export as a jpeg

If you need to the still, just use copy merged and paste the composite into a new layer first

Hope that helps - please ensure you have the copyright holders permission to edit the file.
