What is Frame Rate?
Frame rate, expressed in frames per second (fps), refers to the number of still images displayed sequentially per second to create the illusion of motion in video. Common frame rates include 24fps, 25fps, 30fps, 50fps, and 60fps. The higher the frame rate, the smoother the perceived motion.
Why Frame Rate Matters
Frame rate directly impacts how video appears to viewers and affects technical compatibility across different platforms. It influences motion smoothness, the "feel" of footage, and whether content meets broadcast or streaming specifications.
In the UK, 25fps is the PAL standard used for terrestrial and cable television broadcasting. This is critical when producing content for traditional TV channels like the BBC, ITV, or Channel 4. However, global streaming platforms (Netflix, YouTube, Amazon Prime) typically accept multiple frame rates.
Common Frame Rates and Uses
24fps – Cinema and cinematic content. Creates a slightly dreamlike quality associated with feature films.
25fps – UK and European broadcast television (PAL standard). Essential for compliance with Ofcom regulations and traditional TV distribution.
30fps – North American broadcast (NTSC standard). Also used for some corporate videos and streaming content.
50fps/60fps – Sports, fast-action content, and high-frame-rate broadcasts. Provides ultra-smooth motion for live events.
Practical Considerations for Agencies
When briefing video production for UK clients, confirm whether content is destined for broadcast (requiring 25fps), streaming (flexible), or cinema (24fps). Mixing frame rates within a project creates technical problems during editing and delivery.
For social media campaigns, 24fps or 25fps remains standard, though vertical video for TikTok and Instagram Reels adapts to platform specifications automatically.
Technical Implications
Frame rate affects file size, rendering time, and playback compatibility. Higher frame rates demand more processing power and storage, which impacts production budgets and delivery timelines. Interlaced formats (common in UK broadcast) use half-frames, complicating the technical picture further.
The Takeaway
Frame rate selection should be determined by final distribution channel, not creative preference alone. Always confirm specifications with broadcasters, platforms, and stakeholders before production begins to avoid expensive post-production corrections.
