For the avoidance of doubt, where the Work is a musical composition or sound recording, the synchronization of the Work in timed-relation with a moving image ("synching") will be considered a Derivative Work for the purpose of this License.
(Is a resizing an abridgement? A condensation? Is it "any other form"?)
If resizing creates a disallowed derivative, and you and I are viewing the picture on different sized monitors, which of us is breaching the contract? :-)
