The Essential Guide to Optimising Video for Mobile & Social

Video isn’t one size fits all anymore. Different platforms Instagram, TikTok, YouTube, each have unique audience behaviours and technical requirements. A format that thrives in one feed will falter in another. To capture attention and drive engagement, your strategy must be platform-native.

Here’s our essential guide on how to produce video content that performs, whether it’s a 9-second Instagram Story or a 60-second website hero clip.

1. The First 3 Seconds: Your Non-Negotiable Hook

On mobile, the choice to scroll away is made in an instant. Your opening is your most critical creative asset.

  • Lead with Value or Intrigue: Immediately answer “What’s in it for me?” Show the end result, ask a provocative question, or use text overlay to state a compelling benefit.
  • Prioritise Visual Dynamism: Use bold movement, a striking close-up, or unexpected visuals. Static openings lose.
  • Ditch the Slow Burn: Brand intros and lengthy titles must go after the hook, not before. Start in media res, in the middle of the action.

2. Aspect Ratio & Format: The Technical Foundation

Getting the canvas right is the first step to a professional, platform-optimised feel.

PlatformRecommended Aspect RatioKey Considerations
Instagram Reels/TikTok9:16 (Full-Screen Vertical)Design for sound off but amazing with sound on. Ensure the story is clear visually. Use on-screen text and graphics that work within a vertical frame.
Instagram Feed & Stories4:5 (Portrait) or 9:164:5 occupies more screen real estate in the feed than square (1:1). Use 9:16 for immersive Stories.
YouTube (Shorts)9:16 (Vertical)Similar to Reels, but YouTube’s audience may expect slightly higher production value. Hook is equally critical.
YouTube (Traditional)16:9 (Landscape)The standard for longer-form content. Ensure key info and subjects are within the “safe area”—a central 4:5 zone—as many viewers may watch on mobile in a vertical, cropped view.
LinkedIn & Facebook1:1 (Square) or 4:5Square and 4:5 formats perform well in the busy LinkedIn/News Feed environment. They are more immersive than 16:9 and don’t require full-screen engagement.

3. Captioning & Engagement: Beyond the Visual

Accessibility drives broader engagement. Subtitles are no longer optional; they are a key performance tool.

  • Always Use Captions: Over 80% of social video is watched without sound. Burned-in, clear subtitles ensure your message is received. Use a clean, legible font.
  • Treat Text as a Creative Element: On-screen text should emphasise key points, reinforce branding, and add rhythm. Sync text appearance with audio beats.
  • Direct Engagement: Use clear, platform-native calls-to-action. Ask a question in the caption, use the poll sticker in Stories, or encourage users to “comment with their take.”

4. Final Technical Optimisation Checklist

Before you publish, run through this list:

  • File Format: Use .MP4 or .MOV with H.264 codec for universal compatibility.
  • File Size & Resolution: Aim for the highest quality within platform limits. For social, 1080p is typically sufficient. For website heroes, use 4K if possible.
  • Colour Profile: For social, always export in sRGB. Rec. 709 colour space can appear desaturated on mobile screens.
  • Thumbnail: On platforms like YouTube and LinkedIn, your custom thumbnail is as important as the video itself. Design a clear, high-contrast image with readable text.

Why This Works: Mastering the Digital Landscape

By treating each platform with intention, you respect the user’s experience and dramatically increase your content’s potential reach and impact. This isn’t just about technical specs, it’s about speaking the native language of each digital community.

At Soho Pixels, we bake these principles into every video we produce, ensuring your content doesn’t just exist online, but thrives there.

Why Your Brand is Losing Attention in the First 3 Seconds (And How to Fix It)

Attention is the most valuable currency in modern media, and it’s depreciating faster than ever. On social platforms and digital feeds, viewers make a subconscious decision to stay or scroll in under three seconds. The stark reality is that most brands lose that battle before their core message even begins.

The issue, however, isn’t audience behaviour. It’s creative intent.

The issue, however, isn’t audience behaviour. It’s creative intent.

Too many campaigns still open with slow logo animations, atmospheric slow builds, or vague, abstract visuals that assume a level of patience audiences simply no longer possess. Today, viewers don’t wait for a payoff, they react instantly. At Soho Pixels, we design every piece of content with the opening moment as the strategic anchor of the entire piece, not a polite preamble.

The Three Common Pitfalls (And What to Do Instead)

If your content is haemorrhaging attention, it’s likely falling into one of these traps in the critical opening frames.

1. The Slow Reveal vs. Immediate Relevance

  • The Pitfall: Opening with a wide, establishing shot of an empty office or a slow pan across a landscape. The viewer is left asking, “What is this, and is it for me?”
  • The Fix: Signal Immediate Relevance. Your first visual or line of text must instantly answer the viewer’s subconscious question: “Is this for someone like me?” Show the subject’s face, the product in use, or use bold text overlay that names the audience or their problem directly. Example: Instead of a wide shot of a gym, open on a close-up of sweaty, determined hands on a barbell.

2. Polished Generality vs. Emotional Disruption

  • The Pitfall: Relying on glossy, generic stock-style imagery that blends into the feed. It’s professional but forgettable.
  • The Fix: Create an Emotional or Visual Disruption. A pattern break is more arresting than polish. This could be an unexpected visual (a surprising use of colour), a raw human moment (a genuine laugh), or a provocative question in text or voiceover. The goal is to trigger a micro-jolt of curiosity or recognition.

3. Atmospheric Ambiguity vs. Clarity of Tone

  • The Pitfall: Using ambiguous, moody visuals or cryptic copy that leaves the viewer confused about the emotional tone. Is this an inspirational piece? A funny one? A serious tutorial?
  • The Fix: Establish Clarity of Tone Instantly. Confusion kills retention faster than lower production value. Use music, facial expression, colour grade, and copy to establish the genre within the first second. A quick, upbeat sonic logo and a smile signal fun. A stark, silent title card signals serious drama.

Our Three-Framework Fix for the First Three Seconds

We structure these openings not as gimmicks, but as a disciplined creative framework.

  1. The “In Media Res” Opening: Start in the middle of the action. Begin with the most compelling moment of the story—the hands struggling with the knot, the chef tasting the dish, the sigh of relief—then loop back to explain how you got there.
  2. The “Text-First” Hook: Use bold, succinct text overlay as your primary hook. State a surprising statistic, ask a blunt question, or present a contrarian opinion. The eye is drawn to readable words, making this a failsafe for silent autoplay.
  3. The “Human-First” Close-Up: Lead with an expressive human face. Our brains are hardwired to focus on faces, especially those conveying relatable emotion, determination, surprise, joy. It creates an instant, subconscious connection.

Fixing the first three seconds isn’t about chasing viral gimmicks. It’s a fundamental sign of respect for your audience’s time and attention. It means designing for how people actually consume content today: with speed, selectivity, and an emotional filter.

Beyond the One-Off: How We Build Content Ecosystems for Paid, Social & Web

Stop repurposing and start engineering. Discover how Soho Pixels plans and produces integrated content ecosystems from the start, maximising ROI and brand consistency across every touchpoint.

Creating one-off pieces of content is no longer just inefficient; it’s a strategic misstep. In a fragmented digital landscape, modern brands don’t need standalone assets, they need connected content systems.

At Soho Pixels, we design content ecosystems. This means every shoot, every campaign, is planned from day one for maximum adaptability across the entire marketing funnel. We consider formats, cut-downs, aspect ratios, and nuanced messaging before the camera rolls, transforming a single production into a versatile library of high-performing assets.

The Problem with “Repurposing as an Afterthought”

The traditional model, create a hero film, then later chop it up for social, often results in forced, ineffective content. The pacing feels wrong, the message isn’t tailored, and the platform’s native language is ignored. It’s a cost-saving measure that costs you engagement.

Our Solution: Engineering for Scale from the Start

We flip the process. Our strategy begins with the ecosystem blueprint. A single, strategically planned production is engineered to deliver a cohesive suite of assets:

1. The High-Impact Hero Asset

The central narrative piece: a 60-90 second brand film or flagship video designed for your website, YouTube, or high-value paid placements. This is where the core story, emotion, and production value shine.

2. Platform-Native Social Edits

These are not mere cut-downs, but bespoke edits crafted for specific platform behaviours:

  • TikTok/Reels: 9:16 vertical, fast-paced, built around a central hook and trend-aligned editing rhythms. Designed for sound-on and utilises native text and effects.

  • Instagram Feed/Carousel: 4:5 or 1:1 ratios, optimised for feed scroll with arresting first-frame visuals and clear in-frame text.

  • LinkedIn/Professional Platforms: Slightly slower pace, focusing on problem/solution messaging, value propositions, and professional testimonials.

3. Performance-Optimised Paid Media Variants

Tailored edits designed for specific campaign objectives:

  • Awareness/Reach: 6-15 second clips focusing purely on the most disruptive visual or emotional hook.

  • Consideration/Engagement: 15-30 second assets that introduce a key benefit or story.

  • Conversion/Action: Clear, benefit-driven edits with strong, direct calls-to-action.

4. Website-Ready Visuals & Derivatives

Simultaneously, we capture and create:

  • Still photography for blog headers and product pages.

  • Animated GIFs for email marketing and support articles.

  • Custom motion graphics for website hero sections.

The Tangible Benefits of an Ecosystem Approach

  • Maximised ROI: A single, well-planned investment yields a year’s worth of high-quality content, dramatically lowering cost-per-asset.

  • Unbreakable Consistency: Every touchpoint—from a TikTok ad to your homepage, feels recognisably part of the same brand world, building stronger recognition and trust.

  • Agile Marketing: You have a ready library of fit-for-purpose assets to deploy rapidly for opportunities or react to trends.

  • Strategic Alignment: Every asset, at every level, serves the core campaign message and business objective.

Content shouldn’t be an endless series of one-off productions. It should be a strategic asset that works harder, lasts longer, and delivers value at every stage of the customer journey.

The Critical Difference Between Content and Creative (And Why It Matters)

Confusing content with creative is a strategic error. We break down the distinct roles each plays in building a brand, from goals and budgets to impact and longevity.

In the rush to stay relevant and feed the ever-hungry algorithms, a crucial distinction has become blurred: the line between content and creative. Treating them as interchangeable is a fundamental strategic error that misdirects budgets, muddies brand perception, and dilutes impact.

The truth is stark: not all content is creative, and not all creative should be treated as disposable content. Understanding their unique roles is essential for building a brand that endures.

Content Fills Feeds. Creative Builds Brands.

Content is the day-to-day conversation. It’s reactive, volume-driven, and often tied to immediacy, a trending topic, a quick response, a social update. Its primary role is to maintain presence, drive engagement, and fuel the top of the funnel. Think of it as the consistent, useful chatter that keeps the community alive.

Creative is the foundational statement. It’s deliberate, considered, and designed for longevity. Its role is to define the brand’s world, establish emotional equity, and shift perception. This is the campaign film, the flagship identity, the core brand narrative, the work that people remember and associate with you years later.

How the Distinction Shapes Your Strategy

Confusing these two leads to poor resource allocation and mismatched expectations.

Aspect Content Creative
Primary Goal Maintain presence, drive engagement, test ideas. Build brand, shift perception, define narrative.
Budget Mindset Efficient, scalable, cost-per-piece. Investment, value-over-lifetime, ROI on equity.
Timeline Fast, agile, often weekly/daily. Long, deliberate, strategic.
Measurement Likes, shares, comments, clicks. Brand lift, sentiment, recall, cultural impact.
Lifespan Short (days/weeks). Long (months/years).

The Soho Pixels Approach: A Strategic Partnership for Both

Our role is to be the strategic partner who understands this ecosystem. We help you navigate when you need scalable, agile content and when you need a defining creative statement. Crucially, we ensure the two work in harmony, not at cross-purposes.

  1. Building a Creative Foundation First: Before scaling content, we ensure the brand’s creative core, its visual identity, tone of voice, and key narratives, is rock-solid. This becomes the filter through which all content is created, ensuring consistency.

  2. Deriving Content from Creative: A powerful creative campaign provides a wealth of assets, themes, and stories that can be intelligently adapted into months of cohesive, on-brand content. The hero film begets the social series.

  3. Using Content to Inform Creative: The engagement data and audience conversations from day-to-day content are invaluable. They provide real-time insights that can shape and validate future creative campaigns, making them more resonant.

Mistaking content for creative leads to a brand that is always talking but never saying anything meaningful. Mistaking creative for content leads to exhausted budgets on masterpieces that are lost in the daily scroll.

The most powerful brands master both: they make a timeless creative statement and then sustain it with intelligent, consistent content. They understand that one feeds the community, while the other defines the culture.
