Identifying animations in the Timeline

Flash Pro distinguishes tweened animation from frame-by-frame animation in the Timeline by displaying different indicators in each frame that contains content.
The following frame content indicators appear in the Timeline:
  • A span of frames with a blue background indicates a motion tween. A black dot in the first frame of the span indicates that the tween span has a target object assigned to it. Black diamonds indicate the last frame and any other property keyframes. Property keyframes are frames that contain property changes explicitly defined by you. You can choose which types of property keyframes to display by right-clicking (Windows) or Command-clicking (Macintosh) the motion tween span and choosing View Keyframes > typefrom the context menu. Flash displays all types of property keyframes by default. All other frames in the span contain interpolated values for the tweened properties of the target object.

  • A hollow dot in the first frame indicates that the target object of the motion tween has been removed. The tween span still contains its property keyframes and can have a new target object applied to it.

  • A span of frames with a green background indicates an inverse kinematics (IK) pose layer. Pose layers contain IK armatures and poses. Each pose appears in the Timeline as a black diamond. Flash interpolates the positions of the armature in the frames in between poses.

  • A black dot at the beginning keyframe with a black arrow and blue background indicates a classic tween.

  • A dashed line indicates that the classic tween is broken or incomplete, such as when the final keyframe is missing.

  • A black dot at the beginning keyframe with a black arrow and a light green background indicates a shape tween.

  • A black dot indicates a single keyframe. Light gray frames after a single keyframe contain the same content with no changes. These frames have a vertical black line and a hollow rectangle at the last frame of the span.
Example with a single keyframe, followed by light gray frames and a hollow rectangle at the last frame of the span.

  • A small aindicates that the frame is assigned a frame action with the Actions panel.

  • A red flag indicates that the frame contains a label.

  • A green double slash indicates that the frame contains a comment.
