You can duplicate, delete, repeat animation frames in the timeline or the frame viewer.
Tap on each frame and select the duplicate, delete, or repeat a frame.
In Frame Viewer
Select one or more frames. You can see a row of buttons at the top-right of the interface.
Left-right: Duplicate, Repeat, Export, Tag, Delete
Duplicate: You can duplicate the frames and edit them individually. When you duplicate frames in row (eg. Frame A1, B1, C1), the app generates the same sequences of frames following the original ones. That means you get a sequence like A1, B1, C1, A2, B2, C2. It’s useful for creating animation loops.
Repeat: When you want to move to remain longer or slower, you can repeat the frames. It’s a helpful technique to control time and movement.
Delete: When a frame is deleted, it’s deleted permanently. Please make sure that you don’t delete the wrong frames.
