Ripple dissolve
Watch as an animation →The scene changes with a rippling, wavy motion, marking a dream, imagination or flashback.
Imagination scenes of "what if...", flashbacks to the past.
It is hard with ffmpeg's basic filters. Use the distortion effects in Premiere, Resolve or After Effects, or generate the first second of B as "dreamlike ripple distortion clearing".
Two-shot sequence: Shot 1, a man looks into a still pond at dusk, ending as the water ripples and his reflection wavers; Shot 2 begins with a dreamlike ripple distortion over the whole frame that clears to reveal a boy skipping stones on the same pond in bright daylight, 3 seconds each, with a soft chime.
