5. Notes
1. Voiceover & Subtitle Dubbing Notes
ꔷ English Letter Pronunciation: If you need each letter of a word to be pronounced individually, add a "space" between the letters. ꔷ Special Character Restrictions: Do not use special characters like arrows (↑↓) to avoid pronunciation errors. ꔷ Recording Subtitle Correction: When using recording voiceovers, be sure to check the ASR recognition results and perform real-time editing to ensure video subtitle accuracy.
2. Material & Generation Limits
ꔷ Digital Human Limit: Only one digital human avatar is supported per page and for the entire video. ꔷ Character Limit: The maximum character count for a single video is 20,000. It is recommended to create long-form content in batches to ensure quality. ꔷ Single Page Writing: The system does not check the single-page generation option by default to maintain script coherence. Please enable it manually as needed.
