# What is the difference between a synchronisation (sync) right and a master-use right, and who do public sources say you ask for each when a film, TV programme or online video uses an existing recording?

Four public sources (PRS for Music, the UK IPO, CBC's producer handbook, the US Copyright Office) describe two layers for an existing recording: the composition (sync, usually publishers) and the specific recording (master, usually the label or recording owner). PRS and CBC both say you may need both and that the exact recording matters. The sources differ in jurisdiction and purpose, and none gives a legal conclusion for a particular cut.

Curator qualifications: All seven excerpts verified. The two-layer model (composition/sync vs recording/master) is consistent across four sources in three jurisdictions; the vocabulary-mapping caution is well founded. Circular 56A wording was confirmed in the raw text layer, since the layout extraction interleaves columns.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
