Vertical video for journalism
Vertical video — filmed or formatted in portrait orientation (9:16 aspect ratio) — is the dominant format for short-form social video on TikTok, Instagram Reels, YouTube Shorts, and Snapchat Spotlight. For UK journalists, it is no longer optional: these platforms have become primary news discovery channels for audiences under 35, and most UK newsrooms now have dedicated social video roles or expectations for reporters to produce vertical content alongside traditional outputs.
The skills and aesthetics of vertical journalism video differ from broadcast: the format rewards directness, energy, and speed. Preambles and slow intros cause scroll-offs in the first two seconds. Captions are essential because most views are sound-off. The informal, hand-held visual style that feels unprofessional in broadcast feels authentic and credible on social platforms.
TikTok publishes a free TikTok for Newsrooms resource guide, and Meta publishes creator guidance for Reels. BBC News and Sky News UK accounts are useful reference points for how established UK broadcasters approach the format.

When vertical video is the right format
- 1Breaking news explainers that need to reach a social-first audience within the hour.
- 2Profile or behind-the-scenes content where the informal aesthetic of vertical video adds authenticity.
- 3Repurposing broadcast or web video content for social distribution — vertical format re-edit.
- 4On-the-ground reporting from protests, events, or locations where a selfie-stick or phone shoot is more practical than full camera kit.
- 5Quick-hit reactions or analysis pieces that a single reporter can produce, caption, and publish without a full production workflow.
Red flags
- Publishing vertical video without captions — the majority of mobile views are sound-off; uncaptioned content loses most of its audience.
- Slow intro — no hook in the first two seconds means the viewer has already scrolled to the next video.
- Horizontal footage cropped to 9:16 — heads and key subjects are cut off at the sides; quality degrades noticeably.
- Key text or faces placed at the top or bottom 15% of the frame — platform UI will overlay these areas on most platforms.
- Using full broadcast-length packages (3-5 minutes) for short-form social — the format demands 30-90 seconds for most news content.
- Reusing broadcast audio levels for social — social platforms normalise audio at approximately -14 LUFS; broadcast typically masters at -23 LUFS.
Vertical video production checklist
- Content is shot or formatted at 9:16 (1080 x 1920 pixels).
- Opening hook is in the first two seconds — a bold statement, question, or visual that creates immediate engagement.
- Captions are accurate, styled, and positioned within the safe zone (central 80% of frame width, central 70% of height).
- Key faces, text, and action are within the safe zone — not in the top or bottom 15% of the frame.
- Audio has been levelled at approximately -14 LUFS for social platforms.
- Video length is appropriate for the platform: under 60 seconds for Shorts; under 90 seconds for Reels; up to 3 minutes for TikTok news content.
- Any archive footage, images, or third-party content included has been cleared for social media use.
- A caption/description has been written for the platform post, including any relevant hashtags.
Captioning tools for social video
The two most-used captioning tools for UK social journalists are CapCut (free, mobile-first, AI captions) and Descript (subscription, AI transcription with full edit integration). Adobe Premiere Pro also offers built-in auto-captions. All three generate accurate captions that can be styled and burned into the video.
Common mistakes
- Treating vertical social video as a simple re-cut of broadcast content — the pacing, style, and hook requirements are fundamentally different.
- Not reviewing auto-captions before publishing — AI caption accuracy is typically 85-95%; errors in names, figures, and technical terms must be manually corrected.
- Publishing at the wrong file format — some platforms reject certain codecs or frame rates; check platform specs before exporting.
- Ignoring platform analytics — each platform provides data on where viewers drop off; use this to improve hook and pacing in future videos.
- Using copyrighted background music without a licence — platforms use content-matching systems that will mute or block unlicensed music; use royalty-free or platform-licensed audio.
- Not checking the video on a mobile screen before publishing — always preview on an actual phone to check caption readability and safe zone compliance.

Frequently asked questions
What are the technical specs for vertical video on TikTok, Reels, and YouTube Shorts?
All three platforms use 9:16 aspect ratio at 1080 x 1920 pixels. For TikTok: MP4 or MOV, up to 4K supported, recommended length 15 seconds to 3 minutes, max file size 287.6MB. For Instagram Reels: MP4 or MOV, up to 90 seconds for Reels (standalone), 1080p recommended. For YouTube Shorts: MP4, up to 60 seconds for Shorts feed (longer videos can be labelled Shorts if they are 9:16). All platforms accept H.264 encoding at 30fps or 60fps — 30fps is the standard for talking-head journalism content.
How important are captions for vertical social video?
Captions are critical. Multiple platform studies consistently report that 70-85% of social video is watched without sound, particularly in feed contexts. Without captions, the majority of viewers will not understand what is being said and will scroll past. Good captions are not just subtitles — they are styled, timed, and positioned to be readable while not obscuring key visual elements. Captioning tools that auto-generate from audio include Descript (AI-powered, high accuracy), CapCut (popular for quick mobile editing), and Adobe Premiere Pro's built-in auto-captions feature.
What makes a good opening hook for vertical news video?
The first two to three seconds of a vertical video determine whether a viewer stays or scrolls. An effective hook for journalism content is typically a bold visual, an unexpected statement, a question that creates immediate curiosity, or a key fact stated directly and quickly. Avoid slow pans, titles over black, or preamble — viewers will scroll before your story starts. Many UK journalists start with the most surprising or dramatic element of the story and structure the rest of the video as explanation and context.
Should I shoot vertical or crop from horizontal?
If the content is planned from the start for a vertical platform, always shoot vertical (portrait, 9:16). Cropping horizontal footage to vertical loses approximately 44% of the horizontal field of view, which typically cuts off either side of the frame. Heads become tightly cropped, two-person interviews lose one subject entirely, and environmental context disappears. The quality loss from cropping is acceptable for occasional repurposing but not for content built around vertical distribution.
What is the 'safe zone' for vertical video?
The safe zone is the area of the frame that will remain visible after platform UI elements (like/share buttons, username, caption text) are overlaid on the video. On TikTok and Reels, platform UI overlays the left side, bottom, and sometimes right side of the frame. The generally accepted safe zone for key visual content is the central 80% of the frame width and the central 70% of the frame height — keep faces, text, and key action within this zone. Most professional video editors create a safe zone overlay guide for vertical projects.
