Extend still images
When you create a background for animation, a still image might remain the same for several frames. Adding a span of new frames (not keyframes) to a layer extends the contents of the last keyframe in all the new frames.
To manually extend
a still image through multiple frames, or to use a shortcut, create
an image in the first keyframe of the sequence and do one of the following:
-
Select a frame to the right, marking the end of the span of frames to add and select Insert > Timeline > Frame.
-
Alt‑drag (Windows) or Option-drag (Macintosh) the keyframe to the right. This creates a span of new frames with a keyframe at the end point.
