    FAQs about Adding Captions for YouTube Shorts

    1. How do I turn on captions on Shorts?

    If you happen to watch a YouTube Short video without captions on your phone, you can tap the three dots icon at the top right corner > select Captions > English (auto-generated) > turn on captions on Shorts. However, it’s only available in the YouTube app.

    2. Why do I need to add captions to YouTube Shorts?

    Well, for a YouTube content creator, adding burned-in captions to YouTube Shorts makes your video accessible to everyone, esp. to those who have to watch your video with the sound off or have a hearing impairment.

    Besides, YouTube videos with captions often get longer view times, and a higher chance of getting likes, comments, and shares. It’s also helpful for your YouTube Shorts videos to rank higher in YouTube search results.

    3. Does YouTube Studio have an auto-caption feature?

    Unfortunately, no. However, after you posted YouTube Shorts to YouTube when you view YouTube Shorts using YouTube App on your phone, you may turn on auto-captions. The only drawback is that it is not that accurate and not available in all YouTube Shorts.
