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.mdto its path. Before generating anything, show the person the options on the how-to page.
A is squashed or stretched toward an edge or the centre and B springs out the same way.

What it does
Built on Rubber Band Bumper by HeyGen (HyperFrames), Apache-2.0. The write-up and recipes below are varg's.
Rubbery scaling along one axis, like the image being sucked in or pulled like elastic.
When: Playful, cartoonish and meme edits; app UI demos.
Watch out: Live-action people in serious contexts; the distortion is comic.
Timing: 0.4–1.2 s (CapCut Squeeze 0.47 s, Stretch 1.2 s, Inhale 0.6 s)
Also called: Squeeze, Stretch, Stretch Left, Stretch Right, Inhale, Shaky Inhale, elastic transition
In FFmpeg
Same size/fps/pixel format on both inputs (see the Normalize card). offset = duration(A) - T = 5.0 - 0.5 = 4.5.
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=squeezev:duration=0.5:offset=4.5[v];\
[0:a][1:a]acrossfade=d=0.5[au]" \
-map "[v]" -map "[au]" -c:v libx264 -crf 18 -c:a aac out.mp4
squeezeh squeezes horizontally.
In HyperFrames
Squeeze from the push family: tween #s1 scaleX: 1→0 (transformOrigin left) and #s2 scaleX: 0→1 (transformOrigin right); elastic: rubber-band-bumper.
In Remotion
Custom presentation: exiting transform: scaleX(${1 - p}) with transformOrigin: 'left'; entering scaleX(${p}) from the right edge, eased with Easing.bezier.
In CapCut
Transitions tab → Distortion / Basic → Squeeze, Stretch, Stretch Left, Stretch Right, Inhale. 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.

More transitions skills
- editly: Declarative JSON5 video editing CLI/API: clips, titles, transitions, audio mixing, rendered with ffmpeg.
- Mix (Cross Dissolve): The two shots blend through each other. The quietest transition: "time passes" or "this continues".
- Dip to Black: A fades to black, then B fades up. Marks the end of a section or a bigger jump in time.
- White Flash: The frame blows out to white for a moment and opens on the next shot. Energy, memory or a camera snap.
- Pull In (Zoom In): The camera rushes into shot A and lands, still moving forward, in shot B. The signature short-form transition.
- Pull Out (Zoom Out): The camera jerks backwards out of shot A and keeps pulling back as shot B settles in.
