Pulse Gain modulates image brightness on a clock you set and lock to your edit's tempo. Drag it onto a clip, pick a waveform, dial the rate and the image breathes, throbs, or strobes in rhythm. Frame accurate and repeatable.It's the gateway effect from the Starve & Pulse pack, my set of five datamosh and color-pulse tools for Resolve. This one's free — keep it, use it in anything.
