About Translate Subtitles

Translate subtitles when a video needs to reach viewers in another language, such as a YouTube tutorial, an online course, a product demo or a short film headed to a festival abroad. Upload the subtitle file and every line is translated while its start and end times stay exactly as they were, so it still lines up with the video. If you don't have a subtitle file yet, Speech to Text can make an SRT from the video to translate here.

Under Result, choose Translation only for a clean track, or Both languages to show the original and the translation together, which language learners love. More options lets you name the source language when a file mixes several. Subtitles are short and lean on context, so watch the video through once before you publish.
