SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires @volcengine/tos-sdk, commander, and includes scripts (resource) and references (resource) components.

What problem does it solve?

When you have long or complex audio/video (meetings, lectures, podcasts, interviews, demo videos), producing accurate transcripts, speaker logs, aligned subtitles, translations, and time-based structure usually requires multiple manual tools and workflows.

Core Features & Use Cases

  • End-to-end multimodal understanding for ASR/AST/diarization: supports plain ASR, per-character timestamp ASR, multispeaker ASR, and diarization with time ranges.
  • Subtitle alignment: aligns provided reference subtitles to produce character-level start/end timestamps for high-precision captioning and karaoke-style effects.
  • Multimodal video-focused outputs: generates audio/visual markdown reports (caption), extracts video timeline JSON, and selects technical-blog keyframes (optionally guided by a transcript).
  • Scales to oversized media: automatically downloads remote URLs or uploads local files to Volcano TOS via pre-signed URLs, splits long media, runs concurrent calls, and merges results with per-part timing.

Quick Start

Ask your agent to run the skill for a remote meeting clip and produce speaker diarization by using the command: bun run skill/scripts/main.ts --task diarize --url "https://example.com/meeting.mp4" --type video --audio-part-type input_audio --out-dir ./out/diarize.

Frequently Asked Questions about doubao-multimodal

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I transcribe a long video and identify different speakers?▼

To transcribe and identify speakers in a long video, you can use automatic media splitting and concurrent requests to process oversized files, producing speaker diarization logs with time ranges and merged per-part timing.

Can I generate karaoke-style subtitles with character-level timestamps from a video?▼

Yes, subtitle alignment aligns provided reference subtitles to produce character-level start and end timestamps for high-precision captioning and karaoke-style effects.

Does the Doubao-Seed multimodal endpoint support audio speech translation?▼

Yes, the Doubao-Seed multimodal endpoint supports audio speech translation, multispeaker ASR, and diarization, outputting usable text, translations, and structured JSON for downstream editing.

How do I process oversized media files locally or from remote URLs?▼

You can process oversized media by downloading remote URLs or uploading local files to Volcano TOS via pre-signed URLs, then splitting the media for concurrent processing and merging the results.

What is needed to run video timeline extraction and keyframe selection?▼

Video timeline extraction and keyframe selection require a YAML-discovered execution via the Bun+TypeScript CLI, automatically downloading media to generate timeline JSON and technical-blog keyframes.

What are the limitations of using YAML-discovered execution for multimodal understanding?▼

YAML-discovered execution limits you to the Bun+TypeScript CLI environment and requires Volcano TOS for local file uploads, meaning you cannot run the process without these specific dependencies.
