Importers

Importers provide video, audio and/or closed captioning from the media source. This source can be a single file, a set of files, a communication link between another application, etc.

Standard importers appear as choices in the File > Import dialog, in the Files of type drop-down menu. Importers can support movies, still images, series of still images, and/or audio. If your importer provides enhanced support for a format already supported by another importer that ships with Premiere, set a high value in imImportInfoRec.priority to give your importer the first opportunity to handle the file.

Synthetic importers synthesize source material, rather than reading from disk. They appear in the File > New menu.

Custom importers are a special type of synthetic importer, implemented to better support titlers. Custom importers can create files on disk; synthetic importers don’t. Custom importers either create new media or import existing media handled by the importer. After the file is created, the media is treated like a standard file by the host application. Additionally, the media can be modified by the importer when the user double-clicks on it in the Project Panel.
