What is MOJO and why does it matter?
Mobile journalism (MOJO) is the practice of reporting, shooting, editing, and publishing video journalism using a smartphone as the primary production tool. It has become a standard workflow across UK newsrooms from the BBC and Sky News to regional broadcasters and digital-first publishers, because modern smartphones produce broadcast-quality video and the equipment fits in a coat pocket.
The BBC was an early adopter of MOJO practices, and BBC Academy publishes free tutorials on smartphone journalism. MOJOfest, the annual UK mobile journalism conference, is the key professional gathering for MOJO practitioners. The kit, apps, and workflow have matured significantly: what once required a camera crew can now be achieved by one journalist with a phone and a few hundred pounds of accessories.
The limiting factor in most MOJO work is not the camera — it is audio. Good audio separates professional MOJO from amateur video. This guide prioritises audio kit and technique alongside the visual elements.
Essential MOJO kit
Smartphone
iPhone 14 or later (ProRes recording support) or Android flagship. Keep storage clear before shoots; delete redundant apps that run in background.
Wireless lavalier mic
RØDE Wireless GO II (iOS/Android) or Hollyland Lark M1. Clip transmitter to subject, receiver to phone via Lightning/USB-C adapter. Major upgrade over built-in mic.
Gimbal
DJI OM 6 or Zhiyun Smooth 5S. Counteracts walk-and-talk camera shake. Requires balancing before each shoot.
Tripod / mini-tripod
Joby GorillaPod or a standard travel tripod with a phone clamp. Essential for static interviews, piece-to-camera, and locked-off B-roll.
ND filters
Magnetic ND filter set (e.g. SANDMARC or Moment). Prevent overexposure in bright UK outdoor light; allow control of shutter speed for natural motion blur.
Portable LED light
Aputure AL-MC or Lume Cube. Compensates for poor indoor lighting at interviews. Critical for low-light news environments.
Power bank
20,000mAh minimum. Smartphone battery drains fast when recording video and running a wireless audio receiver. Always carry a backup cable.
FiLMiC Pro or Filmic Remote
Paid camera app giving manual exposure, focus pull, LOG profiles, and high-bitrate recording. Widely used by professional MOJO journalists.
When MOJO is most valuable
- 1Breaking news situations where deploying a camera crew would be too slow or logistically impossible.
- 2Access journalism in sensitive locations where a full camera crew would be intrusive or refused entry.
- 3Solo reporters required to self-shoot for digital or social video without a videographer.
- 4Social-first video content — Reels, TikTok, Shorts — where a vertical 9:16 format is needed.
- 5Quick-turnaround local news stories where a 2-minute produced package is needed within the hour.
- 6Overseas or travel reporting where luggage weight and customs restrictions make broadcast kit impractical.
Red flags
- Shooting with built-in mic in a noisy or outdoor environment — wind and background noise will make dialogue unintelligible.
- Shooting in portrait mode for broadcast or website video players — locked to 9:16 and unplayable at broadcast specs.
- Running apps in the background during recording — memory pressure can cause the camera app to crash mid-shoot.
- Not checking storage before a shoot — running out of space mid-interview is avoidable.
- Relying on phone autofocus for close-up interviews — autofocus can hunt mid-shot; lock focus manually or use FiLMiC Pro.
- Shooting in very bright conditions without ND filters — overexposed highlights cannot be recovered in post-production.
- Not transcoding HEVC footage before editing — edit crashes or dropped frames on less powerful laptops.
Pre-shoot MOJO checklist
- Phone is fully charged and has at least 20GB free storage.
- Wireless mic transmitter and receiver are paired and batteries are charged.
- Gimbal is balanced with phone attached and firmware is up to date.
- ND filter strength is matched to the expected lighting conditions.
- FiLMiC Pro (or preferred camera app) is set to correct resolution, frame rate, and bitrate.
- I have decided whether I am shooting 16:9 (landscape) or 9:16 (portrait) based on the delivery platform.
- I have a tripod or stable mount for any locked-off shots or piece-to-camera segments.
- I have a power bank and cables for charging on location.
- I have confirmed how footage will be transferred to the edit (cable, AirDrop, cloud upload).

Common mistakes
- Skipping the gimbal balance step — an unbalanced gimbal fights against its motors and produces noisy, jerky footage.
- Shooting at 60fps when the delivery format is 25fps — mismatched frame rates require a speed adjustment that affects audio sync.
- Not monitoring audio levels with headphones during recording — audio problems discovered in post are usually unrecoverable.
- Using digital zoom instead of moving physically closer — digital zoom is a crop that degrades quality; move the camera instead.
- Ignoring background noise when choosing interview locations — traffic, air conditioning, and crowd noise are problems that audio kit cannot always fix.
- Not labelling clips immediately after shooting — unlabelled footage becomes unmanageable after a long shoot day.
