clipsheet

Turn any video into images your AI agent can read.

Playwright, browser-use, multimodal LLM video analysis, and native video APIs are slow — often minutes per run, expensive, and overkill when you just need to see what happened on screen. clipsheet converts any video into a handful of annotated grid images that any vision-capable model can read in one pass. Record a screen, drop in a clip, hand it a product demo — if it's a video, clipsheet can process it.

Any video → 2-4 grid images → one model call. Process multiple videos at once. CPU-only, no GPU, no audio, no API keys. Best for videos under 5 minutes — beyond that, consider Gemini native video or Twelve Labs.

Why clipsheet?

Approach	Time for a 2-min recording	Cost	What the agent sees
Playwright / browser-use	2+ minutes (real-time)	Compute + browser	Screenshots you scripted
Gemini native video	30-60s upload + processing	~$0.02-0.10/min video	Every frame (slow, expensive)
Any video + clipsheet	1-2 seconds processing	Free (CPU-only)	Deduplicated keyframes with timestamps

---

30-second start

pip install clipsheet
clipsheet recording.mp4

Output lands in recording_clips/ next to your video:

recording_clips/
  grid_01.jpg       3×3 mosaic, cells labeled A1..C3, timestamps burned in
  grid_02.jpg       next 9 frames in time order
  manifest.json     maps each cell back to its source timestamp

Use it from your coding agent

Install the skill (one time)

clipsheet init
# or: npx skills add poonamsnair/clipsheet

Then just talk to your agent

Claude Code:

> /clipsheet review this video for bugs: ~/Downloads/bug-repro.mp4
> /clipsheet what errors do you see in these two recordings: flow1.mp4 flow2.mp4

Cursor:

> /clipsheet debug this flow: recording.mp4

Codex CLI:

> $clipsheet what UI states appear in this recording: session.mp4

Any agent with shell access (no skill needed):

> run clipsheet on recording.mp4 and tell me what went wrong

Real-world examples

Debug agentic applications — see how users interact with your agent's UI:

> /clipsheet ~/Downloads/agent-session.mp4
> the chat layer is clashing with the sidebar — what's happening at each step?

Review short-form content — get feedback on hooks, pacing, and visual elements:

> /clipsheet ~/Desktop/reel-draft.mp4
> rate the hook, suggest a better opening, and write the transcript

Debug web animations and 3D components:

> /clipsheet ~/Desktop/animation-bug.mov
> the CSS transition is janky between 0:03 and 0:05 — what's the state at each frame?

Compare working vs broken flows:

> /clipsheet ~/Desktop/checkout-working.mov ~/Desktop/checkout-broken.mov
> what's different between these two?

Batch-review multiple recordings:

> /clipsheet bug1.mp4 bug2.mp4 bug3.mp4
> list every issue you see across all three

CLI reference

Process videos

clipsheet <video> [video2 ...] [options]

Option	Default	Description
-o, --output <dir>	<video>_clips/	Output directory. Auto-created next to each input. Override with -o or CLIPSHEET_OUTPUT_DIR env var.
--grid <RxC>	3x3	Cell layout. 2x3 for larger/more readable cells, 4x4 for dense recordings.
--max-grids <n>	4	Cap on grid images. Bump for videos > 8 minutes.
--fps <n>	4	Sample rate in fps. Higher values catch more transitions but take longer.
--keep-intermediate	false	Keep _raw/ and _cells/ for debugging.
--json	false	Emit a JSON summary on stdout (for piping to jq).
--pretty	false	Pretty-print JSON (only with --json).
-v, --verbose	false	Show sampling details and frame counts.

Examples:

clipsheet recording.mp4                          # output → recording_clips/
clipsheet bug1.mp4 bug2.mp4 bug3.mp4             # process multiple videos
clipsheet bug1.mp4 bug2.mp4 -o ./all-bugs        # all outputs into one directory
clipsheet recording.mp4 --grid 2x3               # larger cells for readable text
clipsheet animation-bug.mp4 --fps 8              # catch fast UI transitions

Other commands

clipsheet init                    # install skill into detected agents
clipsheet init --agent <name>     # scope to specific agents (repeatable)
clipsheet init --force            # overwrite existing skill installs

clipsheet --status                # version, ffmpeg, agents, recent runs
clipsheet --version               # short version string
clipsheet --help                  # full help

Install

pip install clipsheet
# or: uv tool install clipsheet
# or: pipx install clipsheet

ffmpeg is bundled. No separate install needed.

What it does NOT do

• No audio transcription. Use Whisper if you need the soundtrack.
• No video editing, trimming, or transcoding. Different tool category.
• No GPU. CPU-only by design, for portability.

Works on any video format ffmpeg can read — MP4, MOV, HEVC, WebM, MKV, AVI, and more. When not to use clipsheet: if you need frame-by-frame motion analysis, audio understanding, or real-time video streaming, use Gemini 2.5 native video or Twelve Labs.

Performance

clipsheet processing times on a 2024 M-series Mac (CPU only):

Video	Duration	Grids	clipsheet
Agent UI screen recording	21s	2	<1s
Product demo	41s	4	~2s
Product demo	58s	4	~1s
YouTube video (1080p)	69s	4	~1s
Presentation	2 min	2	~2s
Presentation	3.3 min	4	~11s
Screen recording (HEVC)	4.9 min	4	~14s

Where does the time go? clipsheet itself is fast — under 2 seconds for most videos under 2 minutes. When using it through an agent (Claude, Gemini, etc.), most of the wait is the model reading the grid images and generating a response, not clipsheet processing. A typical loop: ~1s clipsheet + ~5s image reading + ~10s response = ~15-20s total.

Requires macOS 10.15+, Linux, or Windows 10+. Python 3.10+.
