You can drag media from the resources area directly onto a layer, or drag it onto the blank canvas to create a new layer. If a media resource is not immediately available, you can use a Placeholder (Controls media type) to occupy the space and position, and replace it later when the media resource is available. Alternatively, you can use a Movie or Image Placeholder resource, which is a dummy resource rendered as a rectangle onscreen. Using the Replace Resource method (Ctrl+drag a resource over the placeholder), you can then replace this placeholder at any time, maintaining previously set parameters.
