VidTransDub

The latest version of the plugin now supports Udemy in addition to YouTube, allowing you to watch Udemy's online courses using the plugin.
YouTube Chinese Dubbing is a browser plugin for watching foreign videos online. Unlike traditional subtitle plugins, it translates the subtitles and directly plays the translated content, eliminating the hassle of staring at subtitles while watching videos and improving viewing efficiency.
Plugin official website: https://www.youtube-dubbing.com
Currently supported features:
1. One-click translation and video playback by clicking the play button
2. Multiple browser support (Chrome-based browsers, FireFox, Safari iOS version)
3. Multi-site support: Currently supports youtube.com and udemy.com
4. Multiple voices: Switch between different voices during playback. Selecting different target languages will trigger different voice libraries
5. Playback speed support (directly adjust the speed on the video being watched, and the plugin will adapt)
6. Adjustment of original and target audio volume (not supported due to iOS system limitations)
7. The plugin is free to use. However, due to the poor quality of YouTube's built-in subtitles, the plugin provides support for AI subtitles, which are the optimized subtitles mentioned before (displayed as a green button). If you have high requirements for translation quality and audio-video synchronization, you may consider upgrading to a membership for a better viewing experience.
