VideoLingo

Huanshere/VideoLingo

One click for speech recognition, sentence segmentation, translation, subtitle alignment and AI dubbing, outputting Netflix-standard single-line subtitles.

Why pick itUses an LLM to understand before translating, then revises, so subtitles beat sentence-by-sentence machine translation. Good for turning foreign-language videos into Chinese subtitles.
