video-transcription

video-transcription is a skill for Claude Code, Codex from BlackBeltTechnology/pi-agent-dashboard. It costs 93 tokens per session (1,685 once invoked), scanned A, original, MIT.

A tool that converts video or audio recordings into SRT subtitle files with speaker labels. SRT is a common subtitle-file format, and speaker diarization identifies which person is speaking.

In plain words
What is it for?
Use it to transcribe MKV, MP4, MOV, M4A, or MP3 files, extract audio when needed, and create subtitles beside the original recordings.
Why use it?
It removes the need to type subtitles manually and can process supported recordings from a directory or selected files.

    Output size or generation rate is not bounded. Unbounded output enables denial-of-service through resource exhaustion, log flooding, or context-window stuffing.
    Fix: Set explicit limits on output length, generation count, and rate. Use max_tokens and truncation to prevent unbounded output.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

video-transcription scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 113 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Video Transcription

Transcribe video and audio files in-place to SRT subtitle format with speaker diarization. Backed by the pi-transcribe CLI (a TypeScript port of the original standalone skill — no Python).

Two backends. Soniox is the default and writes <name>.srt. AssemblyAI is opt-in via TRANSCRIBE_BACKEND=assemblyai, uses the EU endpoint, and writes <name>.diarize.srt — a different suffix, so both can transcribe the same file and you can compare diarization side by side.

TRANSCRIBE_BACKEND=both runs them in one pass: audio is extracted once and fed to both APIs, producing <name>.srt and <name>.diarize.srt together. Use this when the user asks to compare diarization or wants both transcripts.

Usage

Run the pi-transcribe bin, optionally passing a directory or file paths. Output .mp3 (extracted audio) and .srt (subtitles) files are placed alongside the source files.

pi-transcribe [directory | file ...]
  • No argument: scans ~/Movies (default)
  • Single directory: scans the specified directory (e.g. a Google Recorder .m4a export folder)
  • One or more file paths: transcribes exactly those files

Examples:

  • /transcribe — transcribe all untranscribed files in ~/Movies
  • /transcribe /path/to/recordings — transcribe files in a specific directory
  • pi-transcribe "~/Movies/May 28 at 4-04 PM.m4a" "~/Movies/Feb 2 at 5-05 PM.m4a" — transcribe specific files
  • TRANSCRIBE_BACKEND=assemblyai pi-transcribe ~/Movies — use AssemblyAI instead of Soniox (writes .diarize.srt, needs ASSEMBLY_AI_KEY)
  • TRANSCRIBE_BACKEND=both pi-transcribe ~/Movies — run BOTH backends in one pass (writes .srt + .diarize.srt; needs both keys)
  • TRANSCRIBE_BACKEND=assemblyai TRANSCRIBE_LANGUAGE=hu pi-transcribe file.m4a — pin Hungarian instead of auto-detecting
  • MAX_CHUNK_HOURS=4 pi-transcribe ~/Movies — change the long-recording chunk size (default 4.5h Soniox / 9h AssemblyAI)
  • TRANSCRIBE_CONCURRENCY=4 pi-transcribe ~/Movies — change how many files transcribe in parallel (default 8)

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
