Importing an underlay

The underlay is inseparable from the PatchMaker project (composition) and constitutes its basis. Therefore you import an underlay at the moment you create a new project. You can create a project by choosing File|New Project…. A dialog appears suggesting to select a frame from a video sequence.

Along with the selected frame (file), all files from the same folder with identical literal name component will be picked up and loaded, and their numbers will appear on the time ruler. The Start frame property of the composition will be set to the first frame. For example, if a folder contains files f01.bmp — f10.bmp, then the time ruler will look like this:

You can also import an underlay directly from an AE project. Select footage in the AE project window, or a layer in the active composition window. If this layer contains more than one frame, the menu item Animation|Upload as Underlay to PatchMaker becomes available. The PatchMaker menu item with a similar function is After Effects|Import Project.
