Dragging Assets to the Track Editor
You can drag video, audio, and still images to streams in the Track Editor. You can drag
multiple assets, but you cannot drag a folder. See
Adding Video and Audio Assets
details on how the assets are placed in their streams.
You can also drag one or more still images, as well as a folder containing multiple still
images, to a subtitle stream. Each still image creates a subtitle clip. See
for more information.
