Automated media publishing

A computer program product comprising:

• non-transitory computer-readable storage with computer program instructions stored thereon, wherein the computer program instructions, when processed by a computer, instruct the computer to perform a method of editing a media composition, the method comprising:
• enabling an editor to:
• edit the media composition, wherein the media composition includes a compositional object, and the compositional object references a source media asset;
• specify an editorial rendition rule for the compositional object;
• and
• associate the editorial rendition rule with the compositional object of the media composition;
• and
• when a rendition of a given media composition is to be generated, a rendition engine:
• receives the given media composition and an editorial rendition rule that the editor has specified and associated with a compositional object of the given media composition;
• receives a rendition profile that specifies media essence encoding parameters for the rendition of the given media composition;
• inputs a source media asset of the given composition;
• and
• generates from the source media asset of the given media composition the rendition of the given media composition in accordance with the editorial rendition rule of the given composition and the media essence encoding parameters for the rendition of the given composition.

A media composition editing system comprising:

• a memory for storing computer-readable instructions;
• and
• a processor connected to the memory, wherein the processor, when executing the computer-readable instructions, causes the system to:
• enable an editor using a media composition application running on a system to:
• edit the media composition, wherein the media composition includes a compositional object, and the compositional object references a source media asset;
• specify an editorial rendition rule for the compositional object;
• and
• associate the editorial rendition rule with the compositional object of the media composition;
• and
• when a rendition of a given media composition is to be generated, a rendition engine:
• receives the given media composition and an editorial rendition rule that the editor has specified and associated with a compositional object of the given media composition;
• receives a rendition profile that specifies media essence encoding parameters for the rendition of the given media composition;
• inputs a source media asset of the given composition;
• and
• generates from the source media asset of the given media composition the rendition of the given media composition in accordance with the editorial rendition rule of the given composition and the media essence encoding parameters for the rendition of the given composition.
