Summary
A comprehensive guide for instructors and hosts on sharing presentation materials during live webinars using KnowledgeCity's built-in BigBlueButton platform.
Introduction
Once your online class event is scheduled and you want to deliver your content effectively to participants. KnowledgeCity LMS uses BigBlueButton as its built-in webinar platform, offering multiple ways to share slides and presentations during live sessions. This guide covers three available methods to present your content, with recommendations based on your specific needs, whether you're conducting compliance training, product demos, or interactive virtual classrooms.
Requirements
Host/Moderator access to the online class event
Your Presentation materials is ready (PDF, PowerPoint, or Google Slides)
Tested your Audio and Video settings
A stable Internet connection
Option 1: Upload Slides Directly (Recommended for Professional Webinars)
This is the cleanest and most stable method for delivering presentations, especially for larger audiences.
Steps to Follow
Join your online class event as a Moderator/Presenter.
Locate the "+" Actions button in the bottom-left corner of the interface.
Select "Upload a presentation" from the menu.
Choose your file to upload:
PDF (best option, converts cleanly)
PowerPoint (.ppt or .pptx)
Wait for the system to convert your file (this usually takes a few seconds).
Click "Upload" to confirm.
Your slides will now appear in the main presentation area, ready for you to navigate through during your session.
Advantages | Limitations |
|---|---|
Smooth navigation between slides | Animations and transitions are removed (converted to static slides) |
Slide thumbnails appear on the left for easy preview | |
Annotation tools available (draw, highlight, write on slides) | |
Very low bandwidth usage - stable even for 100+ attendees |
Option 2: Share Your Screen (For Animations and Live Demos)
Use this method when you need to preserve animations, show live software demonstrations, Keynote/PowerPoint live or present content that can't be easily converted.
Steps to Follow
Join your online class event as a Moderator/Presenter.
Click the "Share screen" button from the bottom menu.
Choose what to share:
Entire screen - shows everything on your screen.
Application window - shows only a specific program.
Browser tab - shows a specific tab (optimized for video/audio).
Click "Share" to begin.
Participants will now see exactly what you're sharing.
Best for:
PowerPoint presentations with animations and transitions.
Live software demonstrations or walkthroughs.
Showing websites or web-based tools.
Video playback that needs smooth rendering.
Advantages | Limitations |
|---|---|
Preserves all animations and effects | Uses more bandwidth - may lag on slower connections |
Works for any application/ live demos or content type | Less stable on weak internet connections |
Full control over what participants see | Participants don't get slide thumbnails or annotations |
No file conversion needed | Can be harder for participants to follow if you switch between windows frequently |
Option 3: Embed Slides via External Link
This method works if your slides are hosted online and you want to reference them without uploading or screen sharing.
Steps to Follow
Join your online class event as a Moderator/Presenter.
Click the "+" Actions button.
Select "External video" from the menu.
Paste a shareable link to your online presentation (if supported).
Google Slides (with sharing enabled)
Other supported video/presentation platforms
Confirm to embed.
Advantages | Limitations |
|---|---|
Useful for referencing existing online content | Limited platform support - not all services work |
Participants can access slides directly | Less interactive than uploaded slides |
Dependent on external service reliability | |
May have playback or compatibility issues |
Conclusion
Presenting slides effectively during your online class events ensures your participants stay engaged and receive your content clearly. Whether you choose direct upload for stability, screen sharing for animations, or external embedding for convenience, KnowledgeCity's supported BigBlueButton platform provides the flexibility you need. Test your preferred method before your live session, and always have a backup plan ready.
