A short violent shake (often with a zoom) hits on the cut, like an impact or a bass hit. - **Type:** [Effect](https://varg.ai/how-to/effects.md) · [Transitions](https://varg.ai/how-to/browse/skills/transitions.md) - **Slug:** `camera-shake` - **Status:** live - **Publisher:** HeyGen (community) - **License:** Apache-2.0 - **Source:** https://github.com/heygen-com/hyperframes/tree/main/registry/components/camera-shake - **Works in:** Claude Code, Claude.ai, Codex, Cursor, OpenClaw, Gemini CLI, Any MCP client, varg Studio - **Requires:** ffmpeg, HyperFrames (npx hyperframes), Remotion, CapCut (by hand) - **Cost:** Free — the take renders locally; generated footage, if any, bills by the model ## What it does Built on [Camera Shake](https://github.com/heygen-com/hyperframes/tree/main/registry/components/camera-shake) by HeyGen (HyperFrames), Apache-2.0. The write-up and recipes below are varg's. The image jolts in x/y and slightly in scale for a few frames around the cut, then calms. **When:** Drops, punches, slams, gaming and hype edits. **Watch out:** Shaking calm or informational content; long shakes. **Timing:** 0.2–0.8 s (CapCut Shake 3 0.8 s); strongest on the first 3–4 frames **Also called:** Shake 3, Jerky Camera, Zoom Shake 2, Shake down, impact shake, shake transition ### In FFmpeg Shake the first 0.4 s of B with crop offsets driven by sin/cos (crop x/y are evaluated per frame): ```bash ffmpeg -i a.mp4 -i b.mp4 -filter_complex \ "[1:v]crop=w=iw-48:h=ih-48:x='24+24*sin(t*61)*max(0,1-t/0.4)':y='24+24*cos(t*47)*max(0,1-t/0.4)',scale=1280:720,setsar=1[b];\ [0:v][b]concat=n=2:v=1:a=0[v]" -map "[v]" out.mp4 ``` ### In HyperFrames `npx hyperframes add camera-shake` (nine measured handheld/telephoto/rig profiles for any wrapper). ### In Remotion Wrap B in `` where dx/dy come from `noise2D` (@remotion/noise) times a decaying envelope from `interpolate(frame, [0, 12], [1, 0])`. remocn `impact-shake`, `lens-zoom` include shake. ### In CapCut Transitions tab → Camera → Shake 3, Jerky Camera, Zoom Shake 2, Shake down. 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. Or Effects → Video effects → a Shake effect over the first frames of B. ### Ready-made components - [Camera Shake](https://skills.varg.ai/component/hf.camera-shake/) (hyperframes): npx hyperframes add camera-shake - [Impact Shake](https://skills.varg.ai/component/remocn.impact-shake/) (remocn): npx shadcn@latest add @remocn/impact-shake - [Lens Zoom](https://skills.varg.ai/component/remocn.lens-zoom/) (remocn): npx shadcn@latest add @remocn/lens-zoom ### Where this comes from - [FFmpeg filters: crop](https://ffmpeg.org/ffmpeg-filters.html#crop) - [CapCut Help: transitions](https://www.capcut.com/help/transitions-in-capcut) - [CapCut: transition categories](https://capcut.com/resource/add-video-transition-online) - [CapCut transition names + default durations (VectCut metadata)](https://github.com/sun-guannan/VectCutAPI/blob/main/pyJianYingDraft/metadata/capcut_transition_meta.py) - [CapCut transition names incl.
