544 Chapter 18: Video and animation In Adobe Photoshop CS3, you can create frame-based animations by modifying image layers to create movement and change. You can also create images for use in video, using one of many preset pixel aspect ratios. When you're done editing, you can save your work as an animated GIF file or as a PSD file that can be edited in many video programs, such as Adobe Premiere Pro CS3 or Adobe After Effects CS3. In Adobe Photoshop CS3 Extended, you can also import video files and image sequences for editing and retouching, create timeline-based animations, and export your work as QuickTime, animated GIF, or image sequences. Video and animation in Photoshop About animation An animation is a sequence of images, or frames, that is displayed over time. Each frame varies slightly from the preceding frame, creating the illusion of movement or other changes when the frames are viewed in quick succession. About video and video layers in Photoshop Extended Important: To work with video in Photoshop Extended, you must install QuickTime 7.1 (or higher) on your computer. QuickTime is a free download from the Apple Computer website. You can use Photoshop Extended to edit individual frames of video and image sequence files. In addition to using any Photoshop tool to edit and paint on video, you can also apply filters, masks, transformations, layers styles, and blending modes. After making edits, you can save the document as a PSD file (that can be played back in other Adobe applications such as Premiere Pro and After Effects or accessed as a static file in other applications), or you can render it as a QuickTime movie or image sequence. Note: You can work only with the visual images in a video file, not the audio. When you open a video file or image sequence in Photoshop Extended, the frames are contained within a video layer. In the Layers palette, a video layer is identified with a filmstrip icon . Video layers let you paint and clone on individual frames using the brush tools and stamp tools. Like working with regular layers, you can create selections or apply masks to restrict your edits to specific areas of a frame. You navigate through the frames using the timeline mode in the Animation palette (Window > Animation). Note: Video layers do not work in frame mode (Animation palette). You work with video layers just like regular layers by adjusting the blending mode, opacity, position, and layer style. You can also group video layers in the Layers palette. Adjustment layers let you apply color and tonal adjustments nondestructively to the video layers. A video layer references the original file, so that edits to the video layer don't alter the original video or image sequence file. If you prefer to make your frame edits on a separate layer, you can create a blank video layer. Blank video layers also let you create hand-drawn animations.
