The BCC Flutter Cut filter produces a jumpy transition that cuts between the incoming and outgoing clips, with optional insertion of effects, colored frames, and alternate layers. The filter is always self–animating with no need to set keyframes.
The filter renders a sequence of clips that, by default, alternates between the incoming and outgoing clips in a pattern determined by the Outgoing Clip Settings and Incoming Clip Settings groups. The controls in the Colors group allow you to add a pattern of colors or alternate layers to the output sequence. The effect controls at the bottom allow you to add a couple of simple effects to selected clips in the output sequence. The Flutter Cut effect produces (by design) a chaotic and rapidly changing output.
