Let your viewers mess with your camera
Efekti Studio runs the whole effect pipeline in this browser and hands OBS a Browser Source. No install, no driver.
Connect your channel, so Bits and channel-point redemptions can reach your camera.
Drop the Browser Source URL into OBS, or import the ready-made scene collection.
Pick which effects viewers can trigger, and what they cost.
1 OBS browser source
Import the scene collection, or paste this URL into a Browser Source yourself. It carries a render token — treat it like a password.

OBS needs one launch flag. Started normally it refuses the camera outright — how to fix that. The scene collection above already has the rest baked in.
2 Camera & look
Reaches the live OBS source the moment you save.
Camera
A browser hides device names until the page holds a camera permission, so the list is behind a button rather than asked for on load.
Fake sources need no webcam and no camera permission — pick one to go live
without being on camera, which is how to let a Twitch reviewer test your panel.
Test pattern is a moving card; a still plays one of your face-library
photos, so face swaps, expressions and masks fire on it too. Background removal
still wants a real person.
No camera on the machine at all, or OBS without the launch flag? Add
&cam=test to the browser-source URL — that starts
the test card without ever asking for a camera.

Local only — this uses this browser's camera, not the OBS source.

Fires on your live OBS source, down the same path a viewer's Bits redemption takes.
3 What viewers can trigger
Everything in this card saves as you change it — there is no Save button.
Channel points
Real Twitch rewards. Efekti creates and manages them for you.
| Reward | Effect | Cost | Secs | On |

Bits — your extension panel
What the panel sells. Prices must be one of Twitch's Bits products.
| Label | Effect | Bits | Secs | On |
|---|
Community goal
Bits from the whole chat pool toward one big effect.
Face swap library
A face is a photo warped onto yours. A mask is a prop — a helmet, an animal head — pinned rigidly to your head; upload a PNG with transparency and click its two eyes. Viewers trigger either by the effect name on its row.
