pyVideoTrans is an open-source software designed to translate videos from one language to another, including both subtitles and audio dubbing. It automates the entire workflow: first, it transcribes the original video's audio to generate subtitles in the source language. Then, it translates these subtitles into the desired target language. Following this, it uses text-to-speech technology to create a voiceover based on the translated subtitles. Finally, it merges the newly generated voiceover and target language subtitles with the original video footage, producing a fully translated video.

Beyond its core video translation capabilities, pyVideoTrans offers standalone functionalities. Users can perform batch audio or video transcription to SRT subtitles, translate existing SRT subtitle files while preserving formatting and timestamps, and generate voiceovers directly from text or SRT files using various supported channels. It also includes auxiliary tools for merging audio, video, and subtitles, as well as separating vocals from background sounds. The tool supports both local offline models and integration with third-party APIs for its AI functions.
