Vizo user manual

Vizo is Present, Scan, and Live Stream for Mac. Present uses the camera, a whiteboard, or tiles. Scan saves Snapshot, Document, Book, Card, and QR or barcode files. Live Stream publishes the current view over RTMP. A built-in camera or USB webcam works. A document camera is steadier and clearer for paper. Scans and recordings stay on your Mac. Requires macOS 11.5 or later.

1. Install

1. Download Vizo.
2. Open the disk image and drag Vizo to Applications. If macOS says the developer cannot be verified, allow it in System Settings → Privacy & Security.
3. Open Vizo. Grant Camera when asked. Grant Microphone only if you will record voice. Grant Screen Recording when you use Screen Record. The first save to Downloads, Desktop, or Documents may ask for folder access.

2. Connect a camera

1. Choose the built-in camera, or plug in a USB webcam or a document camera. Wait until macOS sees it.
2. Open Vizo and choose that camera in the camera list if more than one device is connected.
3. Point the camera at the desk, a book, or a worksheet. A normal camera works. A document camera is better for paper.

3. Present

Open Present. Pick a source, then use the live tools while you teach or demo.

• Camera — show the live camera feed.
• Board — a light or dark whiteboard when the paper on the desk is not enough.
• Tiles — 2-Grid, 4-Grid, or 6-Grid. Import Image or Take Snapshot, then compare it with the live page. Mask › Cover Up or Highlight marks a region.
• Picture-in-picture — overlay a second camera on the Present view. Choose Circle or another inset shape on the bottom bar.

• Freeze Image — hold the current frame while you talk.
• Zoom, rotate, mirror — match the page to the room.
• Autofocus, exposure, white balance, color — when the desk is too dark or too warm.

4. Annotate while presenting

Use Draw or Text on the live Present view. Switch to Board when you need a blank surface, then return to Camera or Tiles.

5. Record and export

1. From Present, open Record. Choose Video Record for Camera, Board, or Tiles, or Screen Record for the Mac display. Grant Microphone if you want voice; grant Screen Recording for Screen Record.
2. Stop when you are done. Open the clip to trim the ends if needed.
3. Export the recording to a folder you choose.

6. Scan

1. Switch to Scan. Choose Snapshot, Document, Book (Full Spread, Left → Right, or Right → Left), Card, or QR / Barcode.
2. Use auto scan, or crop manually. For several pages, keep capturing into the same batch.
3. A book can stay open — you do not need to unbind it to scan a spread.
4. Choose a format and save: JPEG, PNG, TIFF, PDF, DOCX, XLSX, or PPTX, depending on the scan type. The first save to a system folder may ask for permission.

7. OCR and read aloud

On Present, open Text to Speech to recognize the view. Copy from the text panel, or choose Play Audio to hear it. Scan export to DOCX, XLSX, or PPTX can also use an OCR language on the format menu.

8. Capture History

Open Capture History for recent stills and recordings. Reopen a file, export it again, delete it, or open a still in the annotator to draw on the saved image.

9. Live Stream

1. Set the Present or Scan view you want on air.
2. Open Live Stream.
3. Paste the RTMP server URL and the stream key from your provider (YouTube, Twitch, Livepush, or any RTMP server).
4. Choose Publish. Stop Publish when you are done.
5. To watch a stream, paste a playback URL and choose Play. Exit playback returns you to the camera.

Live Stream only goes where you publish. Play watches a stream that is already on air. Recording a file on the Mac is a separate control.

10. Troubleshooting

• Black preview — another app is using the camera, or Camera permission is off. Quit the other app, enable Camera, reopen Vizo.
• Camera is not listed — choose the built-in camera, or unplug a camera and reconnect it. A normal camera works too.
• Screen Record does nothing — grant Screen Recording, quit Vizo, and open it again.
• Scan looks skewed — switch to manual crop, or flatten the page under the camera.
• Live Stream will not publish — check the RTMP URL and stream key, and that the network allows outbound RTMP.
• Files will not save — allow folder access, or choose a folder in Settings.
