Using the Filmstrip
The filmstrip displays thumbnails of a series of frames in the viewport. Any changes you make in the viewports are automatically updated in the filmstrip. Scroll through the filmstrip to get an overview of your project, or use it to move to a specific frame.
To show the filmstrip:Choose Window | Palettes | Show Filmstrip.
To hide the filmstrip:Choose Window | Palettes | Hide Filmstrip.
Below each thumbnail, the corresponding frame number appears. The current frame is highlighted in yellow. A red line, the Current Frame indicator, marks the position of the current frame in the scroll bar. You can show or hide the frame numbers, and change their display units.
Note: When you scroll the filmstrip, the thumbnails update automatically. Note that the current frame is unchanged: the filmstrip scroll bar is independent of the frame controls.
