Recording

Language note: Media and interface labels remain in their original language. Portuguese labels are kept as displayed, with English explanations where useful.

Overview

Slingui’s virtual classroom recording feature lets teachers capture their live lessons directly from the browser. Recordings can be edited, saved on the platform to share with students, or downloaded to your computer, creating a valuable resource for review and for absent students.

To provide the best experience, recording uses a dedicated Google Chrome extension. Using an extension is a smart way to optimize performance and provide extra features, such as simplified editing tools.

Installation and Activation

Installing the Extension

You only need to install it once.

1. Visit the Chrome Web Store using the official link: Slingui Recording Extension
2. Click “Usar no Chrome” (Add to Chrome) and confirm the installation.

Accessing the Extension

After installation, a Slingui icon will appear in your browser’s extensions bar.

Tip: For quick access, we recommend pinning the extension to your toolbar. Click the puzzle icon (🧩) in Chrome’s toolbar, then click the pin (📌) next to “Slingui Recording”.

Setting Up Your Recording

Clicking the extension icon displays two elements: the settings menu and the toolbar.

In the settings menu, you choose what to record:

Recording Modes

• Screen: Lets you select an entire screen, an application window, or a specific tab to record.
• Tab area: Records only the contents of the browser tab currently open. This is our recommendation for recording lessons in Slingui.
• Camera: Records only your webcam feed, without sharing the screen.

Audio and Video Settings

Below the recording modes, you can select which microphone and camera the extension should use for capture.

Advanced Options

• Click “Show more options” to access additional settings, such as hiding the toolbar during recording.
• In the upper-right corner of the settings menu, an additional menu (”…”) provides more controls, including:
  • Setting a maximum resolution for recording.
  • Enabling backups of all recordings on your computer.
  • Restoring the last recording after an unexpected closure.

Our Recommended Setup

To capture everything happening in the video conference—and nothing else—follow these steps:

1. Open the Virtual Classroom: First, make sure your Slingui lesson tab is open.
2. Launch the Extension: Click the extension icon to open the menu.
3. Select “Tab area”: This mode ensures that only classroom content is recorded (including screen sharing and Whiteboards), avoiding other windows or notifications on your computer.
4. Enable Your Microphone in the Extension: Make sure it is on so your voice is captured clearly.
5. Turn Off the Extension’s Camera: The video conference participants’ cameras will already be captured in the tab recording. Keeping the extension’s camera off avoids an unnecessary overlay.
6. Keep “Push to talk” and “Set an area” disabled:
   • Your microphone status is already automatically synchronized with the lesson.
   • “Tab area” mode already sets the correct recording size, hiding browser and Windows/Mac bars.
7. Enable System Audio: In the top menu, select “Include system audio”. This is essential for the video conference audio (the student’s voice and shared audio) to be included in the final video.
8. Enable Backups: In the top menu, enable “Backup recordings”. This creates a backup of all your recordings directly on your computer. Once you confirm that the upload to Slingui is complete, you can delete these local files to free up space.

The Recording Toolbar

During recording, a floating toolbar provides full control in real time.

• Movimentar (Move): Drag the bar anywhere on the screen.
• ⏹️ Encerrar (Stop): Ends the recording and takes you to the editing screen.
• 🔄 Reiniciar (Restart): Discards everything recorded so far and starts a new recording from scratch.
• ⏸️ Pausar/Retomar (Pause/Resume): Temporarily pauses the recording.
• 🗑️ Cancelar (Cancel): Stops and discards the current recording.
• ✏️ Anotações (Annotations): Add drawings, arrows, text, and even images over the screen.
• 🌫️ Embaçar (Blur): Blur sensitive areas of the screen that you do not want in the final recording.
• ↖ Animação de Clique (Click Animation): Highlights the mouse cursor to draw attention to specific elements.
• 🎤 Microfone (Microphone) and 📹 Câmera (Camera): Enable or disable the extension’s microphone and camera.

⚠️ Important: Independent Camera

It is essential to understand that the camera controlled by the recording extension is independent of the camera you use in the Slingui video conference.

• Disabling the camera in the extension does not disable your camera in the lesson, and vice versa.
• For convenience, disabling and re-enabling the recording extension’s microphone is synchronized with the same option in the Slingui video conference, and vice versa.

Finishing and Saving Your Recording

Clicking “Encerrar” (⏹️) takes you to a preview and editing page.

Basic Editing

On this screen, you can:

• Rename the recording file.
• Make simple trims to remove parts from the beginning or end.
• Insert a new audio track.

Saving Options

1. Save to Slingui (Recommended):

   • Select the option to save to your Slingui account.
   • If prompted, sign in to your account.
   • Wait for the upload to finish. The recording will be available in your library to share with students.

2. Save to Your Computer:

   • Use the download options to save the video file (usually in .mp4 or .webm format) directly to your computer.
