Learn how to make an animated GIF from a video clip using Adobe Photoshop CS4. You'll need to use an external editing program (like Sony Vegas) to create a small clip from your larger video beforehand. From Photoshop, go to "File" and select "Import" and then "Video Frames to Layers" from the pop-up menu and select your video clip. Choose "From Beginning to End" when prompted about range to import. The duration of the video clip will now be displayed in frames. By default, each frame is set to be displayed for 0.5 seconds. You can correct this by selecting all your frames, then selecting "Other" from the arrow beside the frame rates and inputting "0.03" as your delay. Go to "Image" and "Image Size" and you can resize the image as needed for its intended use.
