How do I add captions to a Facebook video?

Drop your video into ReelCaption, fix any wrong words, and pick a style that reads clearly. Then export the MP4 and post it as a feed video or a Reel.

Why burn in captions if Facebook has automatic captions?

Because viewers have to turn Facebook's captions on, and you cannot style them. Burned-in captions always show, and they say exactly what you checked.

Can I use the same video for a Facebook Reel?

Only if it is already vertical. ReelCaption keeps the size of the file you drop in and does not crop, so cut a 9:16 version in your editor first, then caption it.

Add captions to Facebook videos and Reels

Facebook videos start muted in the feed. Burned-in captions make the first seconds readable before anyone turns the sound on. ReelCaption transcribes your video or Reel and exports an MP4 with the captions drawn in.
