The frame splits into a 4×4 grid of tiles that flip one by one to the next shot

Prompt that renders it frame-exact

Add the "GridFlip" transition from GL Transitions (by TimDonselaar, MIT; https://gl-transitions.com/editor/GridFlip, GLSL source https://github.com/gl-transitions/gl-transitions/blob/master/transitions/GridFlip.glsl) between products of a catalog or photos of a recap: 1.2 s, ease-in-out. Thin dividers open between the tiles while they flip. Remotion: npm install gl-transitions @gl-transitions/remotion @remotion/transitions, then a <TransitionSeries.Transition> with presentation={glTransition({ name: "GridFlip", params: { size: [4, 4], pause: 0.1, dividerWidth: 0.05, bgcolor: [0, 0, 0, 1], randomness: 0.1 } })} and timing={linearTiming({ durationInFrames: 36, easing: Easing.inOut(Easing.cubic) })} (36 frames at 30 fps). HyperFrames: draw the GLSL on a full-frame WebGL canvas over the cut, with the outgoing and incoming frames as the from/to textures, and compute progress from the composition time, clamp((t − cutStart) / 1.2, 0, 1) through the easing; never from requestAnimationFrame or a timer, so every frame renders the same. ffmpeg's xfade can't run GLSL. size (ivec2(4)) is columns and rows (try ivec2(3, 5) for 9:16), dividerWidth (0.05) the gaps, bgcolor (black) what shows behind the tiles, randomness (0.1) the flip order and pause (0.1) the hold.
