How to use MultiCam Studio Pro

Step-by-step guide

1. 01

   Allow camera and microphone access

   Open the studio and press “Enable camera & microphone”. Your browser asks for permission — choose Allow. Nothing is captured or sent anywhere; the permission simply lets the page see your devices.

   • If you previously blocked access, click the padlock or camera icon in the browser address bar and set Camera and Microphone back to Allow, then reload the page.
   • On a laptop with a privacy shutter or hardware switch, make sure the camera is physically enabled first.
2. 02

   Add your first sources

   In the Sources panel, add a camera, a screen share or a microphone. Each one appears on the program canvas straight away.

   • Camera: pick the device you want from the list. Repeat to add up to eight cameras.
   • Screen share: your browser asks whether to share a whole screen, a single window or a browser tab. Tab sharing gives the sharpest result for web content.
   • Microphone: adds an audio-only channel to the mixer — use this for a USB or interface microphone instead of the webcam's built-in mic.
   • Use the refresh button if you plug in a device after opening the studio.
3. 03

   Arrange the canvas

   Click a source on the canvas to select it, drag it to move it and pull the handles to resize it. The canvas is your final frame, so what you see is exactly what gets recorded.

   • Layer order decides what sits on top — put a small presenter camera above a full-screen share for a picture-in-picture look.
   • Hold the layout roughly first, then fine-tune with the numeric position and size fields in Properties.
4. 04

   Adjust each source in Properties

   With a source selected, open the Properties panel to control how it looks and how sharp it is.

   • Fit mode: Fill crops the image to your box, Letterbox shows the whole image with bars, Stretch distorts it to fit exactly.
   • Capture resolution: drop a secondary camera to 720p or 480p to save CPU while keeping your main camera at 1080p.
   • Corner radius: round the edges of the source box.
   • Drop shadow: enable it and tune colour, blur and offset to lift an inset camera off the background.
5. 05

   Set your audio levels

   In the Audio Mixer, every audio source has a meter and a gain slider. Speak normally and adjust gain so the meter sits in the upper-middle range and only touches the top on your loudest moments.

   • Use Solo to hear one source on its own while you set it, and Mute to silence a source you don't want recorded.
   • The built-in compressor and limiter catch sudden peaks so the recording doesn't clip.
   • If you hear clicks or crackles, raise the audio buffer size in the recording settings until it is clean.
   • Only sources present in the active scene are heard — a microphone in another scene stays silent.
6. 06

   Build extra scenes

   Create a new scene in the Scenes panel for each look you need — an intro shot, a full-screen demo, a side-by-side interview. Each scene keeps its own sources, layout and audio.

   • Add sources to the new scene separately; nothing is copied from the previous scene.
   • Set the fade transition duration so cuts between scenes look smooth rather than abrupt.
   • You can switch scenes live while recording, and the transition is captured in the file.
7. 07

   Choose your recording settings

   Open the recording controls and set the format and quality before you start.

   • Codec: leave VP9 / WebM selected for the most reliable result. Use H.264 / MP4 only if you specifically need an MP4 file.
   • Frame rate: 30 fps suits talking-head content; 60 fps suits fast motion and gameplay.
   • Video bitrate: higher means sharper and larger. Raise it if a busy screen share looks blocky.
   • Audio bitrate: leave it on Automatic unless you have a reason to override it.
   • Output resolution: compose at 1080p and export smaller if you want a lighter file.
8. 08

   Record, pause and snapshot

   Press Record to start. The header switches to a red REC indicator so you always know you are rolling.

   • Pause holds the recording and resumes into the same file — useful for cutting out interruptions.
   • Snapshot saves a full-resolution PNG of the current canvas without interrupting the recording.
   • Keyboard shortcuts let you trigger record, pause and snapshot without moving the mouse into shot.
   • You can switch scenes, adjust audio and reposition sources while recording.
9. 09

   Stop and save your video

   Press Stop. The studio finishes encoding and the finished file downloads to your computer — usually to your Downloads folder.

   • WebM files play in any modern browser and import into most editors, including DaVinci Resolve, Premiere Pro and CapCut.
   • Keep the tab open until the download appears; closing early can interrupt the file being written.
