How to filter video online

This week, we launched a tool on Kapwing to help users filter videos and adjust color online. Kapwing is the first website that allows you to create a filtered video to publish across platforms. In this post, I’ll show how to use the filters tool and describe some of the use cases.

Why filter a video

Post-processing can’t make up for amazing lighting and color in the original footage, but adjusting and filtering can add an artistic edge to photos and video.

  • Saturate landscapes: Natural lighting is hard to capture, so strengthening the color saturation can help compensate and make a landscape video more compelling. Increasing saturation can especially spice up a hyperlapse or cinemagraph. Norway
  • Make a mundane clip more interesting: If you’ve filmed an every-day moment, make it more special, cinematic, and sharable by applying an interesting filter.

  • Add vignette: Bring an interview subject into focus by adding vignette (a black blur) to the borders of the image or video frame. Vignette

  • Brighten a dark video: Have video footage from a bar or nighttime adventure? You can use Kapwing to increase brightness in a dark video. Just go to the adjust tab and use the sliders to get your video to an idea brightness.

  • Make something look vintage: Try out a Sepia filter or increase the fade to make video feel more aged. You can emphasize the passage of time by shifting between a filtered and unfiltered clip in a longer movie. enter image description here

  • Make portraits pop: Bring out the colors of someone’s eyes and smile by adding contrast if they’re standing against a neutral background

  • Go grayscale: Removing color can add drama to a scene since it emphasizes the silhouettes. grayscale

Building the filtering product was harder than we expected it to be; color is complicated, and color transformation matrices were a throwback to our linear algebra classes from college. But we’re excited to bring video filtering support to the web! Please try it out and let us know what you think.
