claude-real-video

Let Claude — or any LLM — actually watch a video.

pip install "claude-real-video[whisper]"
npx skills add HUANGCHIHHUNGLeo/claude-real-video   # one command, installs the skill into Claude Code, Cursor, Codex, Copilot, Gemini CLI & 50+ agent hosts

Then paste a video link into your agent and ask about it. (CLI-only use? crv "<url>" works with just the pip install.)

Naming: crv is the short name for claude-real-video (the PyPI package). The paid add-on, crv Pro, is sold on Capafy under the listing name "llm-real-video Pro".

Same 58-second clip: fixed 1 fps sampling = 58 frames. crv keeps the 26 that actually differ — and --grid packs them into 3 contact sheets. Fewer tokens, nothing missed.

This free version lets your AI see the video. crv Pro lets it understand it — how it was shot (cut rhythm, camera moves) plus a timestamped timeline of what frames can't show: gestures, expressions, voice pitch shifts, emotion, sound events. One-time founder price $19 through July 31 ($29 from August 1) — get it on Capafy or buy with card via Lemon Squeezy.

Most AI tools don't really see a video. Paste a YouTube link into ChatGPT and it reads the transcript, not the picture. Claude won't take a video file at all. Even Gemini, which can read video natively, has to send it up to Google and samples frames at a fixed interval (1 fps by default), so fast cuts slip past.

claude-real-video does it differently, and the processing runs locally: point it at a URL or a file, and it pulls the frames that actually matter (every scene change, not a fixed quota), throws away the near-duplicates, transcribes the audio, and hands you a clean folder any LLM can read. All the processing happens on your own machine — what gets sent anywhere is only the frames/text you choose to paste into an LLM afterwards.

crv "https://www.youtube.com/watch?v=..."
# → crv-out/frames/*.jpg  +  frames.json (per-frame timestamps)  +  transcript.txt/.json  +  MANIFEST.txt

Then drop the frames + MANIFEST.txt into Claude / ChatGPT / Gemini and ask away.

No terminal needed — run crv-web and a local page opens (Traditional Chinese / Simplified Chinese / English): paste a YouTube or Reels link or a file path, click Analyze, open the result viewer. Video analysis and output generation run on your machine — the source video never gets uploaded. (If you then paste the extracted frames or transcript into a cloud LLM, that data goes to that provider.)

Want to eyeball what the model will see first? Add --viewer — it writes a local viewer.html (video + keyframe grid + transcript) you can double-click open. No network, no extra installs.

Slow-changing content (animation tutorials, gradual morphs, slow pans): add --adaptive — frames are picked against their rolling neighbourhood instead of a fixed threshold, so a 2-3s squash-and-stretch that never spikes any single frame still gets captured.

Text-heavy content (lecture slides, screen recordings, talking-head explainers): add --text-anchors — extra frames are forced at subtitle-cue timestamps, so each spoken segment gets a matching visual even when the scene barely changes. Needs a sidecar .srt/.vtt or an embedded subtitle track — captions burned into the pixels can't be detected. At most one forced frame per second; scene detection is untouched.

Multi-speaker content (interviews, podcasts, meetings): add --speakers — every transcript line gets a speaker label ([SPEAKER_00], [SPEAKER_01], …) so the model can follow who said what. Runs a local diarization model (45 MB, downloads once, no account or token needed). Install with pip install "claude-real-video[speakers]".

Not doing LLM work? It also works as a general-purpose video keyframe extractor — scene-change detection + dedup, no ML models to download.

Using Claude Code — or any coding agent? One command installs the skill (works with Claude Code, Cursor, Codex, Copilot, Gemini CLI and other agentskills.io-compatible hosts):

pip install "claude-real-video[whisper]"
npx skills add HUANGCHIHHUNGLeo/claude-real-video

Then just paste a video link into your agent and ask about it.

git clone https://github.com/HUANGCHIHHUNGLeo/claude-real-video.git
mkdir -p ~/.claude/skills && cp -r claude-real-video/skills/claude-real-video ~/.claude/skills/

New in 0.3.0 — tell it why you're watching, and keep what it finds:

crv "https://youtu.be/..." --why "find the pricing strategy" --kb ~/notes

--why makes the analysis focus on what you care about instead of a generic summary; --kb saves the result as a dated note in your own notes folder, so it doesn't die in crv-out.

Why not just sample frames?

Most "let an LLM watch a video" scripts (and Gemini's own pipeline) grab frames at a fixed interval — e.g. one per second. That over-samples a static screencast and under-samples a fast-cut reel. claude-real-video is smarter:

You feed the model fewer, more meaningful frames — cheaper context, better understanding.

Install

pip install "claude-real-video[whisper]"   # recommended: frames + dedup + audio transcription
pip install claude-real-video              # core only (frames + dedup)

pip extras never install themselves — without [whisper] there is no speech-to-text (videos that ship their own subtitles still get a transcript).

System requirement: ffmpeg

ffmpeg / ffprobe are used for frame extraction and audio, and aren't pip-installable. Install them once:

Verify it's on your PATH:

ffmpeg -version

Transcription uses the whisper CLI (installed by the [whisper] extra, or pip install openai-whisper). Whisper also relies on ffmpeg.

Faster + hallucination-proof transcripts (recommended): install the [fast] extra and crv automatically switches to faster-whisper — same models, same output files, several times faster, and gated by Silero VAD (voice-activity detection): music-only or silent audio yields an honest "no speech" note instead of whisper's classic invented caption. No new flags to learn:

pip install 'claude-real-video[fast]'

If both are installed, faster-whisper wins; if it ever fails, crv falls back to the whisper CLI on its own.

Works on macOS, Windows, and Linux — Python 3.10+.

Usage

# A YouTube / Instagram / TikTok / ... link
crv "https://www.instagram.com/reel/XXXX/"

# A local file, English transcript, output to ./out
crv lecture.mp4 -o out --lang en

# Frames only, no transcription
crv clip.mp4 --no-transcribe

# A login-gated video (your own / authorised use): pass a Netscape cookie file
crv "https://..." --cookies cookies.txt

python -m claude_real_video ... works as an alias for crv too.
