How to translate a YouTube Live stream
Open a YouTube Live stream in Chrome or Edge, capture the tab with TanLens, and read translated captions even when the creator provides none.
To translate a YouTube Live stream, open the watch page in Chrome or Edge and capture that tab with the TanLens extension. The stream’s audio is transcribed and translated as it plays, so you can follow a creator who speaks another language. The transcript can be saved and exported after the stream.
01Start with the player tab
Open the live URL, let the player start, keep the YouTube tab active, then press Start in TanLens. Keep the player audible: muted tabs produce no captions, and headphones do not change what the extension receives. If the creator has their own captions, leave them on and compare; YouTube’s captions stay in the player, while TanLens shows its own panel. For long streams, remember that a single session has a time limit, so a multi-hour broadcast may need a second session.
02Use the transcript after the stream
Save the transcript when you stop, then search for the segments you want to quote or clip. A bilingual SRT is convenient for a video edit because the translation and the original stay in the same cue, while VTT is the better format for a web player. TXT is enough for a summary or a blog post. TanLens does not download the video or read the chat, so the video file and any chat record still need to be captured separately if you need them.
