Abstract
Methods and apparatus are provided to establish temporal alignment of media clips. In an example embodiment, first and second media clips each contain an audio portion and the method comprises: determining an estimated global offset between the first and second clips; choosing a first test region of the first clip and identifying a corresponding second test region in the second clip based at least in part on the estimated global offset. The first and second test regions are compared to determine a local offset.
