Video Transcribe

Use Stardust Video Transcribe to extract transcript text from YouTube and Bilibili video URLs.

Endpoint

https://video-transcribe.preseen.ai/transcribe

OpenAPI:

https://video-transcribe.preseen.ai/openapi.json

Authentication

The bundled client authenticates through the shared Stardust Cloudflare Access client. The first normal request opens a browser for company login; sign in with an authorized @stardust.ai identity. Refresh tokens stay in the local owner-only store and are isolated by service origin.

Check or remove the Video Transcribe session without starting a job:

python3 "$HOME/.agents/skills/video-transcribe/scripts/video_transcribe.py" --auth-status
python3 "$HOME/.agents/skills/video-transcribe/scripts/video_transcribe.py" --logout

Approved headless workloads set both CF_ACCESS_CLIENT_ID and CF_ACCESS_CLIENT_SECRET from their secret manager. Never set only one or expose either value in chat, source, logs, or reports.

Request

{
  "url": "https://www.youtube.com/watch?v=VIDEO_ID",
  "prefer_subtitles": true,
  "langs": ["zh.*", "en.*"],
  "combine_subtitles": false,
  "keep_workdir": false
}

Usage

python3 "$HOME/.agents/skills/video-transcribe/scripts/video_transcribe.py" \
  "https://www.youtube.com/watch?v=VIDEO_ID"

Return the complete response as JSON and save it:

python3 "$HOME/.agents/skills/video-transcribe/scripts/video_transcribe.py" \
  "https://www.bilibili.com/video/BV..." \
  --format json \
  --output "/absolute/path/to/transcript.json"

Prefer server-side ASR instead of platform subtitles, or choose language patterns explicitly:

python3 "$HOME/.agents/skills/video-transcribe/scripts/video_transcribe.py" \
  "https://www.youtube.com/watch?v=VIDEO_ID" \
  --no-prefer-subtitles \
  --lang 'zh.*' \
  --lang 'en.*'

Return the text field to the user or use it as source material for summarization, translation, or analysis. Preserve source, title, and video_id in citations when useful.

Notes

• source=subtitles means the service used platform captions.
• source=funasr means the service downloaded audio and ran server-side ASR.
• For private Bilibili or member videos, configure server-side cookies. Do not send browser cookies in chat.
• The hostname needs its own Cloudflare Access application and AUD. If metadata is missing, rule out a local 198.18.x.x fake-IP/proxy path before treating it as a service-side configuration problem.
