Flash CS5 Basics Tutorial-Understanding of timeline

The timeline is used to organize and control the number of layers and the number of frames that a document's content plays over a specified period of time. As with film, the Flash document will also be divided into frames. Layers are like multiple slide films stacked together, each layer contains a different image that is displayed on the stage. The main components of the timeline are layers, frames, and playhead.

The layers in the document are listed in the column on the left side of the timeline. The frames contained in each layer appear in the row to the right of the layer name. The timeline caption at the top of the timeline indicates the frame number. The playhead indicates the frames that are currently displayed on the stage. When you play a Flash document, the playhead passes from left to right through the timeline.

When the timeline state is displayed at the bottom of the timeline, it indicates the selected frame number, current frame frequency, and elapsed time until the current frame.

Attention:

When you play the animation, the actual frame rate is displayed, and if the computer does not calculate and display the animation fast enough, the frame rate may be inconsistent with the document's frame-frequency settings.

The relationship between the layers

The layers in Flash are the same as in PS. The layer is on the top, and the component is on the stage. As you can imagine, the background layer is always at the bottom! The masking layer and the guide layer are above the cover and the guided layer!
