How to add captions to a customer testimonial video on iPhone
Updated
To add captions to a customer testimonial or review video on iPhone, open the clip in CaptionAddr, let it transcribe the customer’s English speech on the iPhone, fix only the words it misheard in Edit Captions, place the captions clear of the customer’s face and export a captioned copy to Photos with no required watermark. Videos up to 2 minutes are free; CaptionAddr Pro covers up to 30 minutes.
Why caption a testimonial
A testimonial works because a real customer says it in their own words. Many people scroll past with the sound off, so captions let them read what the customer said about your business. They also help viewers who are deaf or hard of hearing.
This guide is about videos where a customer is speaking. If you are the one explaining your own product, see the product demo guide. CaptionAddr burns the captions into the picture, so one exported copy works on your website, in social posts and in messages.
Caption a testimonial video on iPhone
- Record the customer clearly. Film in a quiet spot with the phone or a microphone close to the customer, and ask them to answer in full sentences. Ask for their permission to share the video before you post it.
- 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.
- Fix misheard words only. In Edit Captions, correct your business name, product names and any word the transcription got wrong. You can edit, delete and reorder words, with undo and redo, but keep the customer’s meaning intact.
- 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 bright or busy shots, and drag the captions below the customer’s face.
- Export and share. Tap Export Video to save the captioned copy to Photos. The watermark is off unless you turn it on. Share the captioned copy to your website, social accounts or customers.
Tips for testimonial captions
- Keep it short. One strong answer often works better than a long interview. Trim the clip in Photos before you caption it.
- Don’t rewrite the review. Fix transcription mistakes and drop filler words if you like, but don’t change what the customer said; viewers trust testimonials that sound real.
- Check your own name. Business and product names are the words most likely to need correcting.
- Turn off music while filming. Background music or a busy shop floor can cause missed words; the app doesn’t remove noise.
- Keep your original. CaptionAddr exports a new copy and leaves the original in your library.
Limits
- English only. CaptionAddr transcribes English speech and doesn’t translate, so it can’t caption a review given in another language.
- Captions only. Captions show the spoken words. The app doesn’t add name titles, star ratings, logos or music, and it doesn’t trim or crop.
- Single-word captions. Words appear one at a time, timed automatically, in white uppercase text with a dark outline; there are no brand-color controls or manual per-word timing.
- 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 or review sites.
Frequently asked questions
How do I add captions to a customer testimonial video on iPhone?
Open the clip in CaptionAddr, generate captions on your iPhone, fix any misheard words in Edit Captions, choose a font and size, drag the captions below the customer’s face and export a captioned copy to Photos.
How is this different from captioning a product demo?
The steps in the app are the same. A testimonial is a customer speaking in their own words, so the focus is on recording them clearly and correcting only transcription mistakes, not rewriting what they said.
Can I show the customer’s name on screen?
Not in CaptionAddr. It captions the spoken words only and doesn’t add name titles or text labels. If the customer says their name, it appears in the captions like any other word.
Will there be a watermark on the video?
No watermark is required. A small CaptionAddr watermark is optional and off unless you turn it on.
Is the customer’s video uploaded?
No. Transcription runs on the device, and CaptionAddr doesn’t send your video, audio or captions to its servers for transcription.
