How to add captions to a study tips or student advice video on iPhone
Updated
To add captions to a study tips or student advice video on iPhone, talk to the camera or record a voiceover over your study footage, open the clip in CaptionAddr, let it transcribe the English speech on the iPhone, fix subject terms and numbers in Edit Captions, place the captions clear of your notes and export a captioned copy to Photos. Videos up to 2 minutes are free; CaptionAddr Pro covers up to 30 minutes.
Why caption study tips
Study tips, such as a note-taking method, a study schedule, a focus routine or advice for your first week of college, are often watched in a library, on a bus or late at night with the sound off. Captions let other students follow every tip without sound, and they help viewers who are deaf or hard of hearing.
This guide is for advice clips students make for other students. For videos a teacher makes for a class, see the classroom video guide; for recorded talks, the lecture guide. CaptionAddr burns the captions into the picture, so they show wherever you post.
Caption a study tips video on iPhone
- Talk, don’t just play music. Keep the iPhone close and say each tip out loud, or record a voiceover over your desk or study-with-me footage. Captions come from your speech, so a clip with only background music gets no captions.
- Choose the video. Tap Select Video in CaptionAddr and pick the clip with Apple’s Photos picker. Vertical, square and landscape videos all work, and the video keeps its shape.
- Let the captions generate. Captions start as soon as the video opens; keep the app open; the English speech is transcribed on your iPhone, not on a server. Stretches that are only music usually have no captions.
- Fix subject terms and numbers. Subject vocabulary, course codes, formulas read aloud, page numbers and study-method names are the words most likely to come out wrong. Correct them in Edit Captions. You can edit, delete and reorder words, with undo and redo.
- Keep your notes in view. Choose one of the 20 fonts and a size that reads on a phone, turn on the tinted background over busy pages, and drag the captions where they don’t cover your notes, screen or planner.
- Export and post. Tap Export Video to save the captioned copy to Photos, then upload it to TikTok, Reels, Shorts or any other app. The watermark is off unless you turn it on.
Tips for study video captions
- Lead with the tip. Say the main point in the first seconds, so the first captioned words tell viewers why to keep watching.
- Number your tips out loud. The app doesn’t add titles or lists, so saying “tip one” and “tip two” gives captioned viewers the structure.
- Say formulas in words. Read an equation the way you would explain it, then check each term in Edit Captions, since symbols and short terms are easy to mishear.
- Delete stray words. Remove any words the app picks up from a roommate, a café or a lecture playing in the background in Edit Captions.
- Keep your original. CaptionAddr exports a new copy and leaves the original clip in your library.
Limits
- Speech only. CaptionAddr captions spoken English. A silent or music-only study-with-me clip gets no captions, and sung lyrics may be missed or misheard.
- No equations or diagrams. The app doesn’t add formulas, diagrams, flashcards, timers or titles, and you can only fix, delete or reorder the transcribed words.
- English only. CaptionAddr transcribes English speech and doesn’t translate.
- Single-word captions. Words appear one at a time, timed automatically, always in uppercase; there are no speaker labels, full-sentence layouts or manual per-word timing.
- No audio changes. The app doesn’t remove background noise or music or change the audio; deleting a word removes it from the captions only.
- 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 study tips video on iPhone?
Say each tip out loud or record a voiceover, open the clip in CaptionAddr, generate captions on your iPhone, fix subject terms and numbers in Edit Captions, drag the captions clear of your notes and export a captioned copy to Photos.
Can I caption a study-with-me video that only has music?
Not on its own. CaptionAddr captions spoken English, and stretches it detects as music only are usually left without captions. Add a short voiceover with your tips first, then caption that.
Will CaptionAddr get subject terms right?
Common words usually come out right, but technical vocabulary, course codes and formulas read aloud can be misheard. Check each one in Edit Captions before you post.
Can I add a formula or a list of tips on screen?
No. CaptionAddr only makes captions from the speech in the video, and you can only fix, delete or reorder the transcribed words. Say the formula or each tip out loud if you want it captioned.
Will there be a watermark on my video?
No watermark is required. A small CaptionAddr watermark is optional and off unless you turn it on.
