## What it is
YouDub WebUI is an open-source AI video localization and dubbing tool that converts YouTube, Bilibili, or local videos into target-language versions with speech recognition, subtitle translation, voice cloning, and audio mixing. It provides a web interface built on FastAPI and Next.js, producing dubbed videos with optional hard subtitles while preserving background audio.

## Use cases
- dub youtube videos into chinese
- translate and dub bilibili videos to english
- add ai voiceover to local video files
- generate translated subtitles for videos
- clone a voice for video dubbing
- separate vocals from background music in a video
- localize video content into multiple languages

## When to choose
- you need an end-to-end local pipeline for translating and dubbing videos
- you want to preserve background music and effects while replacing speech
- you work with YouTube or Bilibili content and need automated localization
- you prefer self-hosted processing with GPU acceleration over cloud services

## When to avoid
- you only need simple subtitle translation without dubbing
- you have no GPU and need fast processing
- you need production-grade Japanese or other less-validated language pairs
- you want a fully managed cloud service with no local setup
