mlevans / howToAnimateGif
Created March 30, 2013 22:58
How to create an animated gif using iMovie and Photoshop (yes I don't have After Effects otherwise this would be super easy)...
1) Open iMovie. Import movie as a new event and add it to a new Project, editing the clip as necessary
2) Go to Projects list, right click on appropriate project and 'Export using Quicktime', select the 'Image Sequence' file type and I would advise setting the fps to around 6-12 (you can do this by clicking 'Advanced'). Once saved you will see you have a bunch of images...
3) Now to Photoshop. Go to File > Scripts > Load files into Stack, to open all frame files into one document as individual layers.
4) Open the Animation panel, and by clicking the options icon, select 'Document Options...' Set the fps to the same as the Image Sequence.
