About submitting to the iTunes Store in Compressor
Compressor can’t directly submit a package to the iTunes Store. Most content creators work with an Apple-approved delivery partner to submit their work to the iTunes Store. For a list of approved delivery partners, see iTunes Store delivery partners.
Additionally, a complete iTunes Store package consists of both assets and metadata. Compressor generates a package without some essential metadata such as the title, synopsis, cast and crew lists, and so on. That data must be submitted via iTunes Connect by an authorized user (usually the delivery partner).
For details about the submission process, see Create an iTunes Store Package with Compressor: Quick Start Guide.
