Tutorial

A short walkthrough of C Studio, from sign-up to going live in OBS.

1. Create an account

Sign up with your email and a password on the sign-in screen. New accounts start with 0 credits — you'll need to top up before you can start a stream (see step 5).

2. Enable your camera

On the Studio page, click Enable camera and allow browser permission when prompted. Your raw feed appears in the left tile; the AI-transformed output will appear in the right tile once you start streaming.

3. Choose a mode

• Realistic — a realism slider controls how much subtle enhancement is applied while keeping you looking natural. Higher values stay closer to your untouched look.
• Stylized — pick a preset (anime, retro VHS, cinematic, background swap, character swap, ...) or write your own custom prompt describing how the video should look.

4. Optional: character or full-body swap

Drop a clear, well-lit photo into the Reference image box to swap yourself for the person in that photo. Works in either mode. For best results, use a photo with similar framing to your camera (a face photo if your camera shows your face; a full-body photo if it shows more).

5. Top up credits

Click Top up in the top bar, choose a credit pack, and complete payment through Korapay's secure checkout. Streaming costs credits per second of active use — the exact rate is shown on the top-up screen. Your balance updates automatically once payment completes.

6. Start streaming

Click Start stream. The AI output tile will briefly show "Stabilizing output..." while Lucy 2.5 locks onto your chosen look, then switch to the live transformed feed. Click Stop stream when you're done — any unused portion of your reserved credits is refunded automatically.

7. Send it to OBS (or any streaming/call app)

C Studio doesn't do the actual calling or streaming — it feeds a transformed webcam into whatever app you use for that. In OBS:

• Sources → + → Browser Source, and paste the URL shown in the Studio's OBS Setup panel.
• Set that source's Width/Height to 1280 × 720 for a pixel-perfect capture.
• Controls → Start Virtual Camera in OBS, then select "OBS Virtual Camera" as your webcam in Zoom, Meet, Teams, Discord, Twitch — anything.

This URL stays the same across every stream you start — add it to OBS once, and it automatically shows whatever's currently live from your Studio.
