Overview

Capture, translate, and overlay subtitles across websites, adjustable text sizing, and dual/single subtitle translation.

This is an extension I made to help with my own language learning as I tried several other similar extensions and they either did not work well or were far too convoluted for no apparent reason. This extension utilizes Google Translate to convert subtitles either by downloading and translating an srt file or by converting them on the fly as they are generated. It should work across multiple streaming services and video platforms. Useful features include text scaling, dual or single subtitle mode and the ability to cache translated subtitles and pull back up videos you have already translated through your own open subtitle library. If you find any issues with a specific website, please load the subtitles on a video and attempt to run this extension, then when it fails click the troubleshooting dropdown at the bottom and click download subtitle debug dump. If you open an issue on my github page and send me the dump file there, I will look into patching for it. https://github.com/stefman69/OpenSub-Overlay If you like and use this extension regularly, consider buying me a coffee! https://buymeacoffee.com/stefman69
