Frame-by-frame animation changes the contents of the Stage in every frame. It is best suited to complex animation in which an image changes in every frame instead of simply moving across the Stage. Frame-by-frame animation increases file size more rapidly than tweened animation. In frame-by-frame animation, Animate CC (formerly Flash Professional CC) stores the values for each complete frame.
To create a frame-by-frame animation, define each frame as a keyframe and create a different image for each frame. Each new keyframe initially contains the same contents as the keyframe preceding it, so you can modify the frames in the animation incrementally.
You can convert a classic tween or a motion tween span to frame-by-frame animation. In frame-by-frame animation, each frame contains separate keyframes (not property keyframes) which each contains separate instances of the animated symbol. Frame-by-frame animation does not contain interpolated property values.
Usually, one frame of the animation sequence at a time appears on the Stage. To help position and edit a frame-by-frame animation, view two or more frames on the Stage at once. The frame under the playhead appears in full color and apply color and alpha to differentiate between past and future frames.
Color coded onion skin is applied by default. To retain the old behavior, ensure to modify the past and future frames to black.
Onion skinning color coding helps you distinguish between the past, present, and future frames. Onion skin frames that move away from active frame appear with progressively decreasing transparency.
- To customize the color of the onion skin frames, select the Onion skin frame in the Timeline bar.
- Select Edit>Preferences.
- In the Onion Skin Color option, select the color swatch buttons to customize and set colors for the Past, Present, and Future frames.
Color code is also applicable for outline mode.
- To change the position of either onion skin marker, drag its pointer to a new location. Normally, the onion skin markers move with the current frame pointer. Use Control/Command+ drag to increase or decrease the position on both sides.
- To enable editing of all frames between onion skin markers, click the Edit Multiple Frames button . Usually, onion skinning lets you edit only the current frame. You can display the contents of each frame between the onion skin markers and edit them.
- To move the loop range across the timeline to any position that includes the playhead position, use the markers in the timeline to hold the Shift key and drag the range.
- To set the range markers, use the Shift key and drag the range markers or the loop range using the markers across the Timeline.
Locked layers (with a padlock icon) are not displayed when onion skinning is turned on. To avoid a multitude of confusing images, lock or hide the layers you don’t want to be onion skinned.
Always Show Markers
Displays the onion skin markers in the Timeline header whether or not onion skinning is on.
Locks the onion skin markers to their current position in the Timeline header. Usually, the onion skin range is relative to the current frame pointer and the onion skin markers. Anchoring the onion skin markers prevents them from moving with the current frame pointer.
