How to shoot vertical video on an iPhone for UK small businesses

What to take away

Shoot 9:16 from the first frame at 1080p or 4K, with focus and exposure locked before each take.
British daylight is short from November to February, so plan interior shoots around midday.
You need a lawful reason to film staff and customers, and consent for anyone in a paid ad.
A five-minute test clip on location prevents a wasted return trip.

Set the phone up before you leave the office

Most vertical video problems are created before recording starts. Charge the phone, clear storage and switch on Airplane Mode so a call cannot cut a take in half.

Pre-shoot iPhone setup

Charge phone and clear storage
Switch on Airplane Mode
Pick 1080p or 4K at 30 fps
Turn on Grid for framing
Lock focus and exposure
Record five seconds and check sound

Set the phone up

Open Settings, then Camera, then Record Video, and pick 1080p at 30 fps or 4K at 30 fps.
Switch on Grid under Composition so the rule-of-thirds lines guide your framing.
Turn on Formats, then Most Compatible, if you will edit on a Windows laptop.
Tap and hold on your subject to lock focus and exposure, then drag the sun icon down.
Record five seconds, play it back with headphones, and check the sound.

iPhone camera settings for vertical video

iPhone camera settings

Setting	What to choose	Why it matters
Resolution	1080p, or 4K if you crop	1080p uploads faster over shop wifi
Frame rate	30 fps indoors, 60 fps for movement	60 fps allows slow motion in the edit
Grid	On	Keeps a talking head on the upper third
Focus and exposure	Locked before the take	Stops the image pulsing as people move
White balance	Locked after a white card test	Prevents colour shifts between takes
Audio	Phone within a metre, or a lavalier mic	Onboard mics pick up room echo

Lock focus and exposure on the subject, then leave the frame alone; reframing mid-clip is what makes phone footage look amateur.

The 9:16 frame is the default shape for social clips, and the reference notes on vertical video explain how the format developed. Shooting that shape natively beats cropping a wider file later.

Work with British light, not against it

From October to March, useful daylight in England can be gone by mid-afternoon, so book interior shoots around midday.

Overcast skies act as a large softbox, which flatters skin and product surfaces. A north-facing window gives the same even light all day, so it suits a fixed filming spot.

Mixed light is the common failure. Overhead strip lights sit at a different colour temperature from daylight, and locked white balance will render one of them green.

If you need more light, place one LED panel about 45 degrees to the subject and match the room's colour temperature.

Permissions, people and places

Filming identifiable people is processing personal data, so lawful basis and transparency rules apply to a phone as much as to a studio camera. The ICO's UK GDPR guidance sets out the principles to work through.

A shop, salon or office is private property, so film inside only with the owner's permission. Many councils and shopping centres also ask for a permit before commercial filming, so check ahead.

When a client asks whether phone-shot content earns its keep, ONS digital economy data on internet use and online sales is a stronger answer than opinion.

Choose the destination before you shoot

Where a clip will be published shapes how you shoot it, because a Reel and a TikTok reward different pacing. Our comparison of Instagram Reels vs TikTok for UK business sets out which audience each platform reaches.

A product demo needs a close, steady hand on the item, while a talking head needs space above the shoulders for captions.

Move the file off the phone

Move the file off

Play the take on the phone and delete anything unusable before it reaches a laptop.
Rename files by date, client and shot so a month of footage stays searchable.
Transfer by cable or AirDrop, then back the folder up to cloud storage.
Keep the original vertical file and export edits at 1080p in 9:16.

Move footage off the device the same day, because 4K clips fill a phone quickly.

Captions and accessibility

Auto-captions from the phone app are a starting point, not a finished file, because names and product terms are usually wrong. Most viewers watch with the sound off, and captions are also essential for viewers who are deaf or hard of hearing. The workflow in our guide to short-form video captions and UK accessibility applies to phone footage too.

Common questions

Do I need a tripod to shoot vertical video on an iPhone?

Not strictly, but a clamp and tripod remove handheld wobble and free both hands. For a talking head, rest the phone at roughly chest height.

What frame rate should I choose?

30 fps suits most indoor shoots at 1080p or 4K. Use 60 fps only when you plan to slow the clip down later.

Can I film in a public place without permission?

On public land, usually yes, though commercial shoots often need a council or landowner permit. You still need a lawful basis for any identifiable person.

How do I avoid soft phone footage?

Lock focus on the subject, avoid digital zoom, clean the lens and keep the phone steady. Crop in the edit rather than zooming while recording.
