collection_id to restrict a search to one collection’s videos. This is faster than searching your entire account, since fewer vectors need to be compared, and it’s more precise when your library holds unrelated content — a “Sales calls” collection and a “Product demos” collection shouldn’t surface each other’s moments.
collection_id — there’s no whole-library text search. Image queries can omit it to search across every collection in your account.
Discovering collection IDs
list_collections (see MCP Overview) does the same thing as a tool call.
Searching across everything
Omitcollection_id entirely on an image search to check your whole account at once — useful for something like scanning every collection for a specific logo or product appearance. See Collections for how videos get organized into collections in the first place.
