A video background in Slack huddles, on your Mac
Updated October 2026 · checked against Slack huddles's own documentation
Short answer
Slack doesn't offer your own video as a huddle background. Its huddles help covers reactions, effects and stickers, not custom backgrounds (checked October 2026). Choose Backdrop Cam as your camera in Slack and the huddle sees you in front of your video.

How to use a video background in Slack huddles
Pick your video in Backdrop Cam
Click the Backdrop Cam icon in the menu bar, then the background thumbnail. Add a clip with +, from Photos, or by dragging a video file in. Click a tile to use it.
Choose Backdrop Cam in Slack
In Slack, open Settings → Audio & video and set Camera to Backdrop Cam. In a huddle, you can also switch camera from the huddle's settings.
Turn on your camera in the huddle
Click the camera icon in the huddle window. Everyone sees you in front of the video.
Why a virtual camera works in Slack
Slack takes whatever camera you choose. Backdrop Cam delivers finished video with you already cut out, so Slack doesn't need a background feature at all. It works in the Slack desktop app and in Slack in the browser.
Questions
Can I change the background in a Slack huddle?
Slack doesn't document custom backgrounds for huddles. With Backdrop Cam as Slack's camera, you appear in front of any video you pick.
Can I blur my background in a Slack huddle?
On a Mac with Apple silicon you can use macOS's Portrait effect from the Video menu in the menu bar. For a video instead of blur, use Backdrop Cam.
