More on InstagramTo add captions to a video on iPhone with Vyra, add your footage and ask the app to caption the speech. Check the words, choose the style and position, then export the captioned video to Photos. You can move or style one caption and apply that change to the whole track.
For a first edit, use a clip with one speaker and clear audio. Get the transcript right before spending time on animation. Names, numbers and specialist terms are worth checking closely.
Caption a video in the iPhone app
- Add the video. Open Vyra on iPhone, start a project and pick your clip from Photos. AI features need an internet connection.
- Ask for captions. In chat, write "Add captions to the speech in this video. Use short phrases and keep the original audio."
- Read along with the audio. Play the video and compare the captions with what you said. Ask for corrections to names or other words that were transcribed incorrectly.
- Set the style. Choose a readable size and position. The current iPhone app lets you move or style one caption, then apply the change to the whole track.
- Check the whole frame. Keep captions away from your face, the object you are showing and the area where TikTok or Reels puts its buttons.
- Export and check. Save the video to Photos or share it from your iPhone. Watch it muted once to check readability, then with sound to check timing.
A simple caption style to start with
| Choice | Starting point | Reason |
|---|---|---|
| Phrase length | A few words at a time | The reader can follow a sentence without every word flashing |
| Color | White with a dark outline or background | Text stays visible across changing footage |
| Position | Lower-middle, above the app controls | It leaves the center available for the subject |
| Line breaks | At a natural pause | The phrase reads more easily |
| Emphasis | One important word or number | The key point stands out without changing every caption |
These are starting points. Check the result on your phone at its normal viewing size. A caption that looks readable while you zoom into the editor may still be too small in the exported video.
Prompts to try
Add captions to all the speech in this video. Use 3 to 5 word phrases, bold white text with a dark outline, in the lower-middle of the frame. Keep them clear of my face.
The name is Aly, not Allie. Correct that spelling in the captions and leave the spoken audio unchanged.
Keep the caption style consistent across the whole video. Move the captions a little higher so the Reels controls won't cover them. Leave my pacing and music as they are.
Fix common caption problems
| Problem | What to change |
|---|---|
| A name is spelled wrong | Give the exact spelling in chat, then check every occurrence |
| A long phrase is hard to read | Ask for shorter phrases and natural line breaks |
| Text disappears on a bright shot | Add a dark outline or background |
| Captions cover the product | Move them away from the detail you are showing |
| One caption has a different style | Apply the intended style to the whole caption track |
| Captions appear during a quiet section | Check the timing against the spoken audio |
If the recording is hard to hear, caption accuracy can suffer too. Listen before exporting. A generated transcript still needs a review. If the words are correct but appear at the wrong moment, compare the preview and saved file using the caption timing guide.

FAQ

Yes. Add your video and ask for captions in chat. Vyra generates captions from the spoken audio, and you can review and style them before exporting.
Can I use the same caption style across the video?
Yes. Move or style one caption and apply that change to the whole track in the current iPhone app.
Can I fix a word without changing the audio?
Yes. Ask for the spelling correction and say to leave the spoken audio unchanged. Check the corrected caption in the preview.
Can I save the captioned video to Photos?
Yes. Export the finished video to your photo library, or share it from your iPhone.
Does Vyra have an Android caption app?
There is no Android app yet. These steps are for the native iPhone app.
