How to add captions to a fitness video on iPhone
Updated
To add captions to a fitness or workout coaching video on iPhone, record your cues without loud music, open the clip in CaptionAddr, let it transcribe your English speech on the iPhone, check exercise names and rep counts in Edit Captions, then export a captioned copy to Photos and add any music when you post. Videos up to 2 minutes are free; CaptionAddr Pro covers up to 30 minutes.
Why caption a coaching clip
People watch workout tips in the gym, on a commute or with the sound off. Captions let them read your form cues and counts at a glance, and they help viewers who are deaf or hard of hearing.
CaptionAddr captions spoken English only. It works well for coaching clips where you talk to the camera, and poorly for workouts set to loud music, so the steps below keep your voice clear.
Caption a fitness video on iPhone
- Record your voice clearly. Turn the gym or speaker music down while you film, and keep the phone or a microphone close to you. Loud music under your voice is the most common cause of missed words.
- Choose the video. Tap Select Video in CaptionAddr and pick the clip with Apple’s Photos picker. Vertical and landscape clips both work, and the video keeps its shape.
- Let the captions generate. Captions start as soon as the video opens; keep the app open; your English speech is transcribed on your iPhone, not on a server.
- Check exercises and counts. In Edit Captions, correct exercise names, numbers of reps and sets, weights and times. You can edit, delete and reorder words, with undo and redo.
- Style and place the captions. Choose one of the 20 fonts and a size that reads on a phone, turn on the tinted background over busy gym footage, and drag the captions where they don’t hide the movement you’re showing.
- Export, then add music. Tap Export Video to save the captioned copy to Photos. If you want a soundtrack, add it in the app you post to, after the captions are made.
Tips for workout captions
- Cue between reps. Heavy breathing and clanking weights can cover words, so give the main cue before or after a set rather than during the hardest rep.
- Say numbers clearly. Counts and weights are short words that are easy to mishear; check every number before you post.
- Use a mic for outdoor sessions. Wind and traffic can drown out your voice outside. A clip-on microphone helps.
- Keep your original. CaptionAddr exports a new copy and leaves the original clip in your library.
Limits
- Made for speech. Captions show what you say. CaptionAddr isn’t made for song lyrics and doesn’t add exercise labels, timers or sound descriptions.
- No music removal. The app doesn’t separate your voice from background music or change the audio, so speech under loud music may come out with missed or wrong words.
- English only. CaptionAddr transcribes English speech and doesn’t translate.
- Single-word captions. Words appear one at a time, timed automatically; full-sentence layouts and manual per-word timing aren’t available.
- Length. Free covers videos up to 2 minutes; CaptionAddr Pro covers up to 30 minutes. The App Store shows the current Pro price in your currency.
- Burned-in captions only. There is no SRT, VTT or text export, and the app doesn’t post to social platforms.
Frequently asked questions
How do I add captions to a workout video on iPhone?
Film your cues with the music turned down, open the clip in CaptionAddr, generate captions on your iPhone, check exercise names and counts in Edit Captions, choose a style and export a captioned copy to Photos.
Will captions work with music playing?
Quiet background music is usually fine. Loud music under your voice can cause missed or wrong words, and CaptionAddr doesn’t remove music. For the best results, record without music and add it afterwards in the app you post to.
Can it caption the lyrics of a workout song?
It isn’t made for that. CaptionAddr is built for spoken English, so sung words are often missed or wrong, and a clip with no speech can show that no English speech was found.
Can I fix a wrong rep count or exercise name?
Yes. Open Edit Captions to correct any word, delete extras or reorder words, with undo and redo.
Is there a watermark on the captioned video?
No watermark is required. A small CaptionAddr watermark is optional and off unless you turn it on.
