Ever heard someone say “just set it to 24fps” and wondered if they’re actually right? While 24 frames per second has been the go-to standard for decades (thanks, film industry!), it’s not always the best choice for your animation or VFX project. Let’s break down when to use different frame rates and why sometimes you need to break the “rules.”
The Classic 24fps: Friend or Foe?
24fps became the industry standard in the 1920s when filmmakers needed to balance motion quality with production costs. Film was expensive, and every extra frame meant additional costs. Today, it’s still widely used because it gives that classic “cinematic” look we’re all familiar with. Think Marvel movies with their seamless blend of VFX and live action, or your favourite animated series – that slight motion blur is 24fps in action.
But here’s the thing – not all animation needs that traditional film look. Modern displays and platforms have evolved far beyond the limitations of early film, opening up new possibilities for how we create and display motion.
When to Shake Things Up
Here’s when you might want to consider different frame rates:
- Social Media Content (30fps or 60fps) Most social platforms and mobile devices display content at higher frame rates. Using 24fps here can actually make your animation look choppy or less smooth than intended. Social media users are scrolling quickly, and you need your content to catch their eye with smooth, fluid motion.
- UI/UX Animations (60fps) Nobody wants janky interface animations. For smooth transitions and micro-interactions, 60fps is your best friend. Users might not consciously notice it, but their brains will thank you. When users interact with an interface, they expect immediate, fluid responses to their actions.
- Gaming and Real-time VFX (60fps+) If you’re creating animations or visual effects for games, higher frame rates are crucial. The interactivity demands smoother motion, and gamers can spot a choppy animation from a mile away. This is especially important for character animations, particle effects, and environmental motion.
- Traditional Animation Style (12fps or 15fps) Sometimes less is more. Many classic animated shows use lower frame rates to great effect. This technique, often called “animating on twos” (12fps) or “on threes” (8fps), can create a distinctive style that stands out in today’s ultra-smooth digital world.
The Truth About Frame Rates
Here’s what nobody tells you – the “right” frame rate depends entirely on your project’s needs. It’s like choosing the right brush for a painting. Sure, you could use the same brush for everything, but why limit yourself?
Consider these factors:
- What platform will this run on?
- Who’s your target audience?
- What style are you aiming for?
- What’s your production timeline?
- What’s your distribution method?
Pro Tips From the Trenches
- Test Early: Always do a quick test render at different frame rates before committing to the full project. What looks good in your head might not work in reality. Testing a short sequence can save you hours of revision later.
- Mix and Match: Some modern animations use different frame rates within the same project. Main action might be at 24fps while UI elements run at 60fps. This hybrid approach can give you the best of both worlds.
- Consider File Size: Higher frame rates mean larger files. For web content, this could affect loading times and user experience. Make sure your chosen frame rate balances quality with practical delivery constraints.
- Watch Your Motion Blur: Different frame rates need different approaches to motion blur. What works for a VFX shot at 24fps might look weird in a UI animation at 60fps. Adjust your motion blur settings based on your frame rate and movement type.
Making the Final Call
The best frame rate is the one that serves your project’s purpose. Don’t get caught up in what’s “traditional” or “standard.” Instead, focus on what delivers the best experience for your specific needs. Test your animations on the actual platforms where they’ll be viewed, and don’t be afraid to adjust your frame rates accordingly.
Remember – animation is about creating illusions. Whether you’re using 12fps or 60fps, what matters is how effectively you’re telling your story or conveying your message. Your choice of frame rate should support your creative vision, not restrict it.
