Producing subtitles for video and audio content requires juggling transcription services, translation tools, timeline repair, and video burning across disconnected tools. This Skill covers the full subtitle lifecycle in one place: automatic speech-to-text with word-level timestamps, multilingual translation, timeline repair, and subtitle burning into video.
Ask the assistant to generate subtitles for a video file by providing its path, for example: create subtitles for /videos/interview.mp4 with speaker diarization enabled.

Use the auto_subtitle mode with the video file path to transcribe speech via Paraformer-v2 with word-level timestamps. Enable diarization_enabled to separate multiple speakers, and character_identify_enabled to map SPEAKER_xx labels to character names.
Use the translate mode with your SRT path and set target_lang to en. The default qwen-mt-flash model offers the best value, and enabling bilingual keeps both original and translated lines in the output.
ASS burning uses FFmpeg natively and is the recommended default for most videos. HTML burning uses Playwright with Chromium for custom CSS styling but is slower, roughly 340 ms per frame, so it suits videos under 3 minutes.
Yes, auto_subtitle mode requires a DashScope API key for Paraformer-v2 ASR, configured in the plugin settings. Repair and burn modes run entirely locally with FFmpeg and cost nothing.
FFmpeg's subtitles filter misinterprets Windows drive-letter paths unless the filename= keyword prefix is used. The plugin handles this escaping automatically, so failures usually indicate FFmpeg is missing from PATH or the SRT is not UTF-8 encoded.
Files over 2 GB or audio longer than 12 hours are rejected with a duration error kind. Split large media into smaller segments before submitting, and note that Paraformer tasks time out after 900 seconds by default.
