AI-Powered Video Assembly: Seamless Audio & Subtitle Integration

AI-Powered Video Assembly: Seamless Audio & Subtitle Integration

This AI agent skill enables the final assembly of videos by integrating voiceover audio tracks and generating subtitles. It lowers the volume of original audio during voiceovers and supports subtitle file generation and embedding. This process culminates with the normalization of audio loudness.

What this skill does

• Places segments of voiceover audio on the video timeline according to predefined positions.
• Lowers the original audio level during voiceover segments, supporting fixed, sidechain, and zone modes.
• Generates subtitles.srt files based on voiceover positions, with optional burning of subtitles.ass into the video.
• Optionally normalizes the final loudness to a target LUFS (Loudness Units relative to Full Scale).
• Uses input files such as the source video and tts_meta.json for voiceover positioning and output generation.
• Outputs final video and subtitle files, along with metadata and timeline models.

Who it is for

This skill is ideal for developers and teams using AI coding agents such as Claude Code, Cursor, and Codex, who require automated video production capabilities.

Use cases

• Automating the integration of voiceover and subtitles in video post-production tasks.
• Creating accessible video content with embedded subtitles and synchronized voiceovers.
• Streamlining video assembly processes in media production workflows.

Technical details

The skill leverages AI agent capabilities to automate video assembly tasks. It uses specific input contracts involving video files and metadata detailing voiceover segments. Outputs include stable video files, synchronized subtitle tracks, and comprehensive timelines for further editing or review.
