Pixelate — effect skill for transitions

For AI agents: find the right skill in one call — curl -s "https://skills.varg.ai/api/search?q=<what the person wants>" returns the matching how-to page and the best skills with install commands, as markdown (Russian works too). Full index: https://skills.varg.ai/llms.txt. Every page has a markdown twin: add .md to its path. Before generating anything, show the person the options on the how-to page.

A breaks into ever larger pixels, swaps at the coarsest point, and B sharpens back.

What it does

Built on Pixelize by gre (gl-transitions), MIT. The write-up and recipes below are varg's.

Blocky mosaic grows then shrinks; reads as digital or retro gaming.

When: Gaming, retro, tech, censorship gags.

Watch out: Serious brand films; very large blocks on vertical video lose the subject.

Timing: 0.4–0.8 s (CapCut Mosaic 0.47 s)

Also called: Mosaic, pixelize, 8-bit transition, pixel dissolve

In FFmpeg

Same size/fps/pixel format on both inputs (see the Normalize card). offset = duration(A) - T = 5.0 - 0.6 = 4.4.

ffmpeg -i a.mp4 -i b.mp4 -filter_complex \
"[0:v]fps=30,settb=AVTB,format=yuv420p[a];[1:v]fps=30,settb=AVTB,format=yuv420p[b];\
[a][b]xfade=transition=pixelize:duration=0.6:offset=4.4[v];\
[0:a][1:a]acrossfade=d=0.6[au]" \
  -map "[v]" -map "[au]" -c:v libx264 -crf 18 -c:a aac out.mp4

In HyperFrames

npx hyperframes add grid-pixelate-wipe; dithered: ordered-dither-pass.

In Remotion

glTransition({name: 'pixelize'}) (1.x name; Pixelize in 2.0) or @remotion/effects/pixelate driven by interpolate() on a canvas-based <Video>.

In CapCut

Transitions tab → Glitch / Basic → Mosaic, Blocks. Desktop: drag the tile onto the cut between two clips and set Duration in the right panel ("Apply to all" reuses it on every cut). Mobile: tap the small white square between clips, pick the transition, drag the duration slider, tap ✓. Tab labels and placement change between versions and regions.
