Press CTRL+. or click the settings icon on the seek bar to open the settings window.

4. Download Whisper Model for ASR

From Subtitles > ASR section, please download Whisper's models for whisper.cpp. You can choose from a variety of models, the larger the size, the higher the load and accuracy.

Note that models with En endings are only available in English.

Audio Language allows you to manually set the language of the video (audio). The default is auto-detection.

If you want to use the faster-whisper engine instead of whisper.cpp, please download the engine instead of models from the settings. With faster-whisper, selected model is automatically downloaded the first time, so no prior download is required.

A description of each engine can be found here.

5. Set Translation Target Language

To use the translation function, please set your native language. This is called the target language. The source language is detected automatically.

From Subtitles > Translate section, please set the Target Language at the top.

If you want to use another translation engine, you will need to configure it in settings. You will find detail information in here.
