Translation Channels (Subtitle Translation) ​

Translation channels translate subtitles from their original language into other languages—for example, converting Chinese subtitles into English, or vice versa. It connects to various translation services to quickly and accurately translate subtitles generated by speech recognition into your desired target language.

Some translation services require information such as an API URL, Secret Key (SK), etc. You can easily configure them under the Translation Settings option in the top menu bar of the software.

Translation results may show blank subtitle lines or large chunks of text. Click here to see why. Solution: Menu → Tools → Advanced Options → Subtitle Translation → Lines per batch for traditional translation channels / Lines per batch for AI translation → Set both to 1
