FAQPage Schema

How do I automatically generate subtitles for my video from voiceover metadata?▼

This Skill automates subtitle generation by consuming voiceover_metadata.json to produce synchronized bilingual subtitles in Chinese and English. It aligns each subtitle with actual voiceover timing and exports a subtitles.json file for use in your Remotion project.

Can I generate bilingual subtitles for both Chinese and English in a single pass?▼

Yes. The Skill creates dual-language subtitles from voiceover_metadata.json, supporting both single-language and bilingual display modes. You control the output format through the SubtitleDisplay component in your Remotion project.

What input format do I need before running the subtitle generation?▼

You need voiceover_metadata.json placed in your project's designated location. This file contains timing and content data that the Skill reads to generate time-aligned subtitles without requiring external API calls.

How do I display generated subtitles in my Remotion video project?▼

After the Skill generates subtitles.json, import the SubtitleDisplay component from the Skill's local templates into your Remotion composition. The component renders the synchronized subtitles with customizable styling.

Does this Skill work with existing Remotion video projects?▼

Yes. The Skill targets Remotion-based projects and integrates with your repository's local components and templates. It generates subtitles.json as a standalone output that your existing Remotion composition can consume.

What are the limitations of automated subtitle generation from voiceover metadata?▼

The Skill depends on accurate voiceover_metadata.json timing and supports Chinese and English only. Complex transcription, speaker identification, or languages beyond this pair require manual review or upstream preprocessing.
