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.

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.

Options

What --grid output looks like

One contact sheet = nine consecutive keyframes, in order, filenames on each cell — the model reads a sequence, not scattered stills:

Use it from Python

from claude_real_video import process

r = process("https://youtu.be/...", "out", lang="en")
print(r.frame_count, r.transcript_path)

How it works

1. Fetch — yt-dlp for URLs (optional cookies), or copy a local file.
2. Extract — one chronological ffmpeg select pass grabs every scene change
   plus a density floor (at least one frame every --fps-floor seconds), so
   fast cuts and slow screencasts are both covered.
3. Dedup — two detectors against a sliding window of the last
   --dedup-window kept frames, so an A-B-A cutaway doesn't re-send a shot the
   model has already seen. A global channel measures real pixel difference
   (downscaled RGB, not a perceptual hash — hashes go blind on flat colours and
   equal-luma hue changes); --dedup-threshold is the % of it that must change.
   A settled-local channel (v0.7.4) catches what the global one can't see:
   thin pen strokes, caption/text-card swaps and small UI updates that average
   out to ~0% globally. It looks, on a finer signature, for a region that
   differs strongly from every recent kept frame (with 1px shift tolerance, so
   film grain and frame jitter don't trigger) and is no longer changing — a
   settled new state, not motion mid-flight — with a cooldown so continuous
   motion that pauses every second (a waving flag, drifting smoke) can't keep
   re-firing. The final frame is evaluated even if still in motion (so a video's closing state is never lost), but it must clear both contrast gates like any other frame. --report writes report.html showing every keep/drop decision
   with its diff % (settled-local keeps are labelled), for tuning.
4. Text — if the video already has subtitles (a sidecar .srt/.vtt next to a
   local file, or an embedded subtitle track), those are used as the transcript —
   faster and more accurate than re-transcribing. Only when there are no subtitles
   does it fall back to Whisper on the audio (skipped cleanly if there's no audio).
5. Audio (optional, --keep-audio) — save the full original soundtrack
   (audio.m4a: music + speech + effects, copied losslessly when possible). The
   transcript only has the words; the audio file lets a model that can listen
   (Gemini, GPT-4o, …) actually hear the music and tone.
6. Timestamps — every kept frame's source-video time survives the whole
   pipeline (extraction → dedup → --max-frames thinning → renaming) and is
   written to frames.json (file / timestamp_sec / timestamp /
   selection_reason). Cite visual evidence as frame_012 @ 00:03:41, align
   frames with transcript.json segments, or feed the map to a video-RAG
   pipeline. In viewer.html, click any keyframe → "play video from here".
7. Manifest — MANIFEST.txt summarises everything for the model.

So the model can see (key frames), read (transcript) and — with --keep-audio —
hear (full soundtrack) the video. The transcript is plain text any model can read;
the tool doesn't burn subtitles into the video — burning is a presentation choice,
not something needed to make a video AI-readable.

Notes

• Only download content you have the right to. The --cookies option is for
  your own, authorised access — don't ship credentials in a repo.
• Use one output folder per video. Re-running into a folder that already holds
  an analysis is refused (so two videos never mix); pass --overwrite to replace it.

crv Pro — understand how a video was shot

The free tool gives your AI keyframes and a transcript — enough to know what a video is about. crv Pro adds everything else: how it's shot, how it's cut, how it's spoken, what it feels like. All computed on your machine, written as plain text any LLM can read.

• Camera & pacing (--motion) — every shot auto-labelled: static, pan, tilt, zoom, handheld. Full shot table: per-shot duration, cuts per minute, pacing across open/middle/close. High-motion shots get 0.2s-apart burst frames.
• Sound & emotion (--senses) — voice emotion, tone curves and audio events (laughter, SFX, ambience) timestamped segment by segment. Vocals and music auto-separated: emotion reads the clean voice, music gets its own BPM + energy track. No-dialogue footage (MVs, film) falls back to reading mood from color and light.
• Interactive viewer (--viewer) — one self-contained web page per analysis: the video, a clickable event timeline that jumps to the second, a transcript that highlights along with playback. EN / 繁中 / 简中.
• Two reports, one flag (--ai-report) — with your own API key: one report on how it's shot, one on what it says.
• Breakdown report (--breakdown) — hook analysis, pacing curve, camera language, and a rubric your own LLM completes into a full teardown.
