In order to increase the reach of my YouTube channel COMMAIK specifically for German and English-speaking viewers, I have set up separate channels: “COMMAIK” with videos for the DACH region and “CommaikEnglish” with content for the international audience in English. In this article, I describe my approach to translation, the technical background to this decision and the use of the AI tool HeyGen for lip-synchronous translation and dynamic video length adjustment. HeyGen offers the possibility to translate videos into different languages, including English, Spanish and Hindi.
