Consider in advance whether translation in different languages is needed. There are several options to translate a video.
One option is to use captions. They can be included using the video production software or – if the video is published via Youtube – captions can be included on the platform in several languages. Keep in mind that for this option language bits on the screen (like text paragraphs or “take-home messages” or language-specific technical terms) need to be avoided.
As an alternative, different language versions of a video can be produced, which comes with full translation of the entire content of the video, including separate narration. While this requires more time and budget, the video will be more easily accessible to the audience. Moreover, text in the visuals can be used in the video, too, which might be helpful or even necessary to transmit the message.
