How auto captions work in nine16
When a YouTube video has captions, nine16 uses them. When it doesn't, or when you upload a file, nine16 transcribes the speech. It times every word, shows a few at a time, and highlights the word being spoken. The captions are burned into the video, so they look the same on every app.

Questions
Are the captions burned in?
Yes. They're part of the video, so they show the same on TikTok, YouTube Shorts, Instagram and Facebook.
What if my video has no subtitles?
nine16 transcribes the speech for you. YouTube videos that already have captions use those.
Can I turn captions off?
Yes. Choose "No captions" for any project.
Do captions cost extra?
No. Captions come with every clip on every plan, including Free.
Where do the captions sit?
Clear of the buttons and text TikTok, Shorts and Reels lay over your video, so nothing covers them.
