Better webcam framing for streamers
Frame your webcam for streams: native 9:16 for vertical broadcasts, 16:9 for shows, mirror control and zero added latency — all in the browser.
Browser-based streaming studios like StreamYard made going live without OBS possible — but your webcam still shoots one shape, and every platform wants a different one. Vertical destinations crop your landscape feed blind.
CamTuner shapes the camera feed at the source: a real 9:16 frame for vertical live, 16:9 for standard shows, plus mirror control for setups that come out flipped.
The camera problems streamers run into
Vertical platforms crop blind
When a landscape webcam feed meets a 9:16 stage, the studio center-crops it — cutting off whatever you framed carefully.
Mirror confusion
Flipped feeds make on-screen text unreadable and your gestures look wrong; some capture rigs make it worse.
Frame drift across a long stream
You start centered; two hours later you've migrated to the edge of the shot without noticing.
The setup that works
Start with a 9:16 crop as the foundation, then layer in the features that fit how streamers work:
Native 9:16 for vertical live
Frame a true vertical shot — TikTok and Shorts-style live stages get a real composition, not a cropped accident.
Mirror and flip controls
Correct the orientation once; the corrected feed is what the studio and the stream receive.
Center Stage for long sessions
Optional face tracking keeps you framed through hours of movement, without you touching the camera.
Tips for streamers
- For simultaneous horizontal + vertical broadcasts, frame for the vertical stage — horizontal crops of a 9:16 feed lose less than the reverse
- Check your framing in StreamYard's device preview before going live; it shows the exact tuned feed
- Keep a second browser profile with a 16:9 preset for guest spots on other shows

streamers webcam FAQ
Does CamTuner work with OBS?
No — OBS captures your camera directly, outside the browser. CamTuner is built for browser-based studios (StreamYard, Restream, Riverside) where the stream flows through Chrome.
Can I run different framings for different streams?
Yes. CamTuner supports per-site settings, so your StreamYard tab can run 9:16 vertical while your Riverside tab stays 16:9.
Does the processing add lag to my stream?
Cropping and zooming add under 2ms — effectively nothing. Face tracking costs more CPU, so enable it only for streams where you move around.
Other call types
Set it up once — every call after that is already framed. No account, fully on-device.
