An organic ink blot, brush stroke or smoke plume spreads over A and B shows through the painted area.

What it does

Built on Scribble Transition by HeyGen (HyperFrames), Apache-2.0. The write-up and recipes below are varg's.

Irregular, hand-made edges bloom across the frame, unlike geometric wipes.

When: Art, travel, food, Asian-inspired themes, creative portfolios.

Watch out: Tech and data content; low-resolution matte assets with visible pixel edges.

Timing: 0.5–2.0 s (CapCut White Ink 0.47 s, Reveal Brush 2.0 s)

Also called: White Ink, Reveal Brush, ink transition, brush stroke transition, paint reveal, Black smoke, White smoke

In FFmpeg

Use an ink/brush matte video (white paint on black) as the mask:

ffmpeg -i a.mp4 -i b.mp4 -i ink_matte.mp4 -filter_complex \
"[0:v]fps=30,settb=AVTB,format=yuv420p,scale=1280:720[a];[1:v]fps=30,settb=AVTB,format=yuv420p,scale=1280:720[b];\
 [2:v]fps=30,settb=AVTB,format=yuv420p,scale=1280:720,format=gray,format=yuv420p[m];\
 [a][b][m]maskedmerge[v]" -map "[v]" out.mp4

(maskedmerge shows B where the matte is white; align the matte's start with setpts=PTS-STARTPTS+<cut>/TB and pad with black.)

In HyperFrames

npx hyperframes add hw-scribble-transition (scribble bands cover the frame, the host cuts beneath, then clear); smoke-like organic: domain-warp-dissolve.

In Remotion

glTransition({name: 'luma', textures: {luma: staticFile('brush.png')}}) animates a luma matte image (1.x name luma, 2.0 LumaWipe); or a custom presentation using a matte <Video> as CSS mask-image.

In CapCut

Transitions tab → Mask / Overlay → White Ink, Reveal Brush, Black smoke, White smoke. 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.
