Once you are satisfied that the old and new movies are aligned properly and all of the correct properties for each frame are selected, you can transfer (copy) properties and objects from the old movie to the new movie. You can do this one frame at a time, or you can click a button to transfer properties and objects for all frames at the same time.
If you want to transfer the properties for all frames, click in the local toolbar.
OR
In the confirmation dialog that opens, click OK.
The properties (at least those selected in the Properties window pane) are transferred from the old movie to the new movie.
Note: Any objects (e.g., shapes, cursor trajectories) from the old movie are automatically transferred, even though they are not shown in the Properties window pane. In addition, any objects that might have been in the new movie are automatically removed from those frames.
