FAQs
What is a light leak overlay?
A light leak overlay is a digital, flexible filter that mimics a natural light leak, or unintentional over-exposure, for artistic purposes. Light leaks traditionally occur with film cameras when stray light penetrates the light-tight chambers of the camera and exposes the film. Even a pinprick of light through a camera’s interior can result in anomalies: flares, flashes, streaks, halos.
Although light leaks in the film are technical glitches—the unintentional results of an error in the filming process—these “accidents” can sometimes bring a certain otherworldly style and vintage ambiance that can be difficult to replicate. (Unless, of course, you’re working with an intelligent editing suite like Runway.)
If you’re working with a digital camera, you can harness the impact of natural light leaks (without any of the unpredictability or overblown distortions) in post-production, thanks to light leak overlays. With a light leak overlay tool at your disposal, you can determine where and when to apply these entrancing glitches—adding a warm, comforting dimension to make your work an instant classic or cleverly distorting a subject to imply a shift in character or narrative.
With Runway, it’s never been simpler to manipulate light leaks in order to achieve your desired aesthetic and surpass the unreliability of traditional film light leaks. Whether you seek flashes of light or a subtle glow, our AI can make your vision a reality.
What are some uses for a light leak overlay?
Generally speaking, a light leak overlay can be used to add dimension to your image and engage audiences with eye-catching movement and shimmer. Runway’s AI-backed light leak overlay is designed to fit your footage flexibly, meaning you can apply it to certain clips or the whole video. Consider using this tool to:
  • Add a warm, sunlit glow to a beach scene or vacation footage
  • Transport your audience to a surreal, rave-like setting with multi-hued flashes
  • Boost motion by adding flickers of pulsing light at the edge of your frame
  • Give sentimental scenes (like birthday party scenes or wedding montages) a nostalgic tone and vintage aesthetic
  • Signify shifts in time or subjectivity with intentional glitches and mind-bending streaks
The point is there are different ways to use this effect to your advantage. No matter how you use Runway’s light leak overlay, you’ll enjoy more creative control than you would by trying to create traditional light leaks. Add this element in post-production to capture all of the magic and surprise that comes with film without obscuring your key images.
Why should you add a light leak overlay to your video?
Applying filters and effects like a light leak overlay to your footage has myriad benefits, especially when it comes to helping you:
  • Engage your audience – A light leak overlay adds motion and texture to your frame without burying the original image. With just enough flare, a light leak overlay can evoke nostalgia or splendor—and draw emotional responses from your viewers. Whether the effect is subtle or brilliant, your audience will have difficulty looking away.
  • Switch it up – Moody, monotone visuals can certainly serve a purpose, but variety keeps viewers engaged. The subtle distortion from a light leak overlay can add a layer of dynamism to your footage post-production. Use our light leak overlay strategically to grab your audience’s attention at various moments throughout or to signify key transitions between narrative arcs or scenes.
  • Set the scene – Worldbuilding immerses viewers in your creation, and our light leak overlay can efficiently foster a sense of setting.

Or, mirror your protagonist’s state of mind with light leaks representing everything from infatuation to intoxication. Whether you’re crafting a commercial or developing a feature-length film, this artistic filter only adds to your narrative’s power.
Whether you’re looking for rainbows or a subtle flash, a light leak overlay empowers you to spend less energy worrying about an unpredictable technique and achieve your dream aesthetic on your terms. Control where, when, and how you’d like to apply the effect without over-exposing key shots or damaging your prime footage.
