Abstract
Parallel video effects, mix trees, and related methods are disclosed. Video data inputs are mixed in parallel according to a mix parameter signal associated with one of the video data inputs. A resultant parallel mixed video data output is further mixed with a further video data input according to a composite mix parameter signal, which corresponds to a product of mix parameter signals that are based on mix parameter signals respectively associated with multiple video data inputs. The mix parameter signals could be alpha signals, in which case the composite mix parameter signal could correspond to a product of complementary alpha signals that are complements of the alpha signals. Composite mix parameter signals and mix results could be truncated based on a number of levels in a multi-level mix tree and an error or error tolerance. Rounding could be applied to a final mix output or an intermediate mix result.
