How to add captions to a car review or walkaround video on iPhone

Why caption car reviews

Car reviews, such as a walkaround, an interior tour, a first drive or a quick “what I like and don’t like” clip, are often watched in feeds with the sound off. They are also filmed in some of the noisiest places for speech: beside traffic, in the wind or inside a moving car. Captions let viewers follow every point without sound, and they help viewers who are deaf or hard of hearing.

This guide is for videos where you show a car and talk about it. For demos of products you sell, see the product demo guide; for road trips and scenery, the travel vlog guide. CaptionAddr burns the captions into the picture, so they show wherever you post.

Caption a car review on iPhone

1. Record the talk where it’s quiet. Film the talking parts parked with the engine off, or stand on the side away from traffic and wind. Captions come from your speech, so engine, road and wind noise can turn words into the wrong ones.
2. 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.
3. 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.
4. Fix model names and numbers. Model names, trim levels, engine terms, specs and mileage 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.
5. Keep the car in view. Choose one of the 20 fonts and a size that reads on a phone, turn on the tinted background over bright paint, chrome or sky, and drag the captions where they don’t cover the car or the detail you’re pointing at.
6. 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 car review captions

• Say the verdict early. Name the car and your quick take in the first seconds, so the first captioned words tell viewers why to keep watching.
• Talk between engine sounds. Let the engine start, the exhaust note or a door close play out, then speak. Revving under your voice can cause missed words.
• Narrate driving footage later. For clips filmed on the move, record a voiceover in a quiet room, add it to the footage in a video editor, then caption the finished clip.
• Delete stray words. Remove any words picked up from passersby, a radio or the car’s own alerts 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. It doesn’t caption engine sounds, music or sound effects, and it doesn’t read badges, screens or window stickers shown on screen.
• Captions only. The app doesn’t add spec tables, ratings, price tags or titles, and you can only fix, delete or reorder the transcribed words.
• No noise removal. CaptionAddr doesn’t clean up engine, road or wind noise or change the audio, so noisy clips may need more corrections.
• 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.
• 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.
