Overview
Adobe Animate documents divide lengths of time into frames similar to films. Frames are at the core of any animation, dictating each segment of time and movement. The total number of frames in your movie, and the speed at which they are played back, together determine your movie's overall length. A brief description of some of the concepts on frames is explained below for your reference.
Frames
In the timeline, you work with the frames to organize and control the content of your document. You place frames in the timeline in the order you want the objects in the frames to appear in your finished content.
Keyframe
A keyframe is a frame where a new symbol instance appears in the timeline. A keyframe can also be a frame that includes ActionScript® code to control some aspect of your document. You can also add a blank keyframe to the timeline as a placeholder for symbols you plan to add later or to explicitly leave the frame blank.
Using keyframe you can set a position, add anchor points, actions, comments and so on.

Span
Span-based frame selection allows you to select a range of frames between two keyframes with a single click.
Static frame span
In static frame span, same content is available for entire duration of span. You can use this type of span whenever you need to display graphics for fixed amount of time.
Tweened frame span
In tweened frame span, the content changes within the span for each frame. You can use this type of span for animations.

Add or insert frames in the timeline
To insert a new frame, select Insert > Timeline > Frame (F5).
To create a keyframe, select Insert > Timeline > Keyframe (F6), or right-click (Windows) or Control‑click (Macintosh) the frame where you want to place a keyframe, and select Insert Keyframe from the context menu.

insert-keyframe
To create a blank keyframe, select Insert > Timeline > Blank Keyframe, or right-click (Windows) or Control‑click (Macintosh) the frame where you want to place the keyframe, and select Insert Blank Keyframe from the context menu.
Effects on frames
The filters and color effects used to be applicable only to movie clips and graphic symbols. With the advanced layers, filters and color effects can now be applied to a selective frame(s), which in turn applies to all its content including shapes, drawing objects, graphic symbols, and so on. Layer effects can also be tweened using classic, shape, and IK tweens across frames.
For more information, see Applying layer effects.
Select and label frames in the timeline
You can select frames by using two methods provided in Animate. You can also label frames to organize its contents.
Animate offers two different methods for selecting frames in the timeline. In frame-based selection (the default), you select individual frames in the timeline. In span-based selection, the entire frame sequence, from one keyframe to the next, is selected when you click any frame in the sequence.
Select frames in the timeline
Single or multiple frames selection
To select one frame, click the frame.
To select multiple contiguous frames, drag the cursor over the frames, or Shift-click additional frames.
To select multiple non-contiguous frames, Control‑click (Windows) or Command-click (Macintosh) additional frames.
To select all frames in the timeline, select Edit > Timeline > Select All Frames.
Span based frames selection
As a prerequisite for span based selection, you can specify span-based selection in Animate timeline by clicking the hamburger icon at the upper-right corner and selecting Span Based Selection menu item.
To select a whole span of frames (motion tween or inverse kinematics) click on frame.
To select multiple spans, click on each of them while holding the Shift key.
Label frames in the timeline
You can label frames in the timeline as a way of helping organize its contents. You can also label a frame in order to be able to refer to that frame in ActionScript by its label. That way, if you rearrange the timeline and move the label to a different frame number, the ActionScript will still refer to the frame label and will not have to be updated.
Frame labels can only be applied to keyframes. A best practice is to create a separate layer in the timeline to contain your frame labels. Using separate layer for labels enables you to organize content and keyframes better.
