Drop in your Short and Just Captions transcribes it and lays down clean, readable subtitles — on your iPhone, in about a minute. Free, private, and kept clear of the Shorts title and action buttons.
The short version: open Just Captions, drop in your clip, and it transcribes the speech and times subtitles to every word automatically. Pick one of four readable presets, then export an MP4 with the captions burned in and upload it as a Short. No timeline, no manual typing, nothing uploaded. Most clips are done in about a minute.
The Shorts player stacks the title, channel row and action buttons over the bottom and right of the frame. Keep text in the upper-to-middle band so nothing gets covered.
| What to set | Recommended for Shorts |
|---|---|
| Aspect ratio | 9:16 vertical (1080 × 1920) |
| Safe zone — bottom | Keep text above the bottom ~15% (title, channel, description) |
| Safe zone — right | Stay clear of the right column (like, dislike, comment, share, remix) |
| Caption position | Centred, in the upper-to-middle band of the frame |
| Burned in vs CC | Burn captions in so they show on mute — CC is toggled off by many viewers |
| Style | High-contrast fill or outline so text reads over any footage |
Just Captions places presets inside this safe area and sizes them for one-glance reading, so the Shorts UI never covers your words.
Free to start, no card, nothing uploaded. Drop in a clip and watch the captions write themselves.
