How to use MultiCam Studio Pro

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.
   • Image and text sources: add a logo, lower third, title or watermark from the same panel and style it in Properties.
   • 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.
   • Open the microphone properties for the noise gate, 3-band EQ, compressor, limiter and A/V delay controls.
   • 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

   Draw with annotations and the whiteboard

   Open the annotation toolbar to draw straight onto the program canvas. Everything you draw is composited into the recording and into snapshots.

   • Pick pen, highlighter, line, arrow, rectangle, circle or text, then set colour, brush size and opacity.
   • Use the select tool (V) to move, resize, rotate or delete a shape, with undo and redo available at any time.
   • Drag a text box and type inside it — the floating format bar sets font, size, weight, alignment and colour.
   • Add a whiteboard source for a clean white, black, grid or dotted page, and switch pages while recording.
   • Scope a layer to the current scene, or keep it global so it stays visible across scene switches.
8. 08

   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.
9. 09

   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.
10. 10

    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.
11. 11

    Trim it in the recording editor

    Every take appears in the Recordings list with an Edit button that opens it in the built-in recording editor. Edits are non-destructive, so the original file is never changed.

    • Scrub the zoomable timeline with its thumbnail strip and waveform, and step frame by frame with J / K / L.
    • Set in and out points to trim, split at the playhead and delete the parts you don't want — deleted sections can be restored.
    • Run Auto Cut Silence to remove every silent stretch automatically, with adjustable threshold, minimum length and padding.
    • Undo, redo and automatic saving mean your edit survives a reload.
    • Export the result as a new MP4 or WebM file at the resolution and quality you choose.

1. 01

   Open the Video Studio Editor

   Click “Video Studio Editor” in the header, or send a studio recording straight into it from the Recordings list. It is a separate full-page editor and, like the studio, it runs entirely on your device.

   • Nothing is uploaded — your media never leaves the browser.
   • The layout is fully responsive, so the same editor works on a phone or tablet.
2. 02

   Import your media

   Drag local MP4, WebM, MOV, MP3 and WAV files into the media pool, or use the import button. Images can be added too.

   • Drag a clip from the media pool onto a track to place it on the timeline.
   • Video clips render a filmstrip of frames and audio clips render a real waveform, so you can see what you are cutting.
3. 03

   Build your timeline

   Add as many video and audio tracks as you need and arrange clips across them. Upper tracks draw on top of lower ones in the composition.

   • Drag clips between tracks and along the timeline, and drag their edges to trim.
   • Press S to split the selected clip at the playhead, D to duplicate and Delete to remove it.
   • Mute, hide or lock any track from its track header while you work.
   • Zoom the timeline in and out to work coarsely or frame by frame.
4. 04

   Position and transform clips on the canvas

   Select a video or image clip and drag it on the preview canvas. Corner handles resize it and the rotation handle spins it — the numbers update live in the properties panel.

   • Use the inspector tabs for transform, crop, opacity and colour filters (brightness, contrast, saturation, blur).
   • Set fade from black and fade to black per clip for clean openings and endings.
   • Add effects and transitions between clips for CapCut-style cuts.
5. 05

   Add text layers

   Add a text layer for titles, lower thirds and callouts. Each text layer gets its own lane on the timeline and sits above the video, and you can reorder the stack.

   • Double-click on the canvas to edit the text inline with the rich text editor.
   • Drag to move it, use the handles to resize it, and trim its lane to control when it appears.
6. 06

   Work with audio

   Select a video clip and press “Split audio” to move its sound onto its own audio track, where you get dedicated audio editing.

   • Set gain in dB with quick ±3 dB steps, add fade in and fade out, or mute the clip.
   • Draw a volume envelope to duck music underneath a voice, and shape the tone with the clip EQ.
   • Adjust clip speed, and use the graph-based speed ramp for smooth slow motion and time remapping.
7. 07

   Record a voice-over

   Choose your microphone, position the playhead and press record voice-over. The timeline plays while you speak and the take lands on a new audio track.

   • Record as many passes as you like — each one becomes its own clip you can trim and level.
   • Mute the original clip audio first if you are replacing the on-camera sound.
8. 08

   Generate captions

   Open the captions panel and generate a transcript from your timeline audio using the in-browser Whisper model. Nothing is sent to a cloud service.

   • Pick Fast, Balanced or Accurate quality and set the spoken language before generating.
   • Non-Latin languages such as Urdu can be transliterated into Roman English.
   • Each generation creates a new caption track, so captions for another clip are never overwritten.
   • Edit captions in the searchable transcript or drag and trim them on the caption lane.
   • Style them with presets, fonts, colours, outlines, position, animation and karaoke highlighting.
   • Import or export SRT and VTT files, and choose whether to burn the captions into the export.
9. 09

   Export your finished video

   Open the export dialog, pick MP4 or WebM, choose 1080p / 720p / 480p, set quality and frame rate, and export. The finished file downloads straight to your computer.

   • MP4 is the default for maximum compatibility; WebM is the most reliable gap-free option.
   • Keep the tab open and the page visible until the export finishes writing.
