Hubilo Broadcasting Studio: Best Practices and System Requirements

This article talks about the streaming best practices and system requirements for the Hubilo Broadcasting Studio.

System Specifications

Ensure optimal performance with these requirements:

• Browser Versions Recommended: 

Note: It is Recommended to have the latest version of your browser

• OS Recommended:
  • Host/Co-host & Speakers:
    • macOS: 8GB RAM (16GB recommended)
    • Windows: 8GB RAM (16GB recommended) 
  • Attendees: 
    • macOS: 4GB RAM 
    • Windows: 4GB RAM 

To ensure the best user experience, best practice is to use the latest version each browser on the latest version of the operating system

System requirements: 

• CPU/GPU Load: Keep CPU usage <70% (close background apps like video editors, games, or file sync tools)

Internet Requirements

• Minimum Speed: 25 Mbps upload/download (stable connection).
• Test Speed: Speedtest by Ookla.
• Avoid: 
  • VPNs: Disable VPNs to prevent latency/bandwidth throttling. 
  • Public Wi-Fi or mobile hotspots (unstable bandwidth).
  • Use a dedicated network connection instead.

Streaming Best Practices

1. Virtual Backgrounds:
   • To get a better virtual background experience, it’s recommended that you use the feature on the latest version of desktop Chrome.
   • Avoid clothing/accessories that match the Virtual Background color palette.
   • Test the lighting setup to ensure no glare or shadows interfere with the Virtual Background 
   • Disable if experiencing lag or high CPU usage
2. Screensharing:
   • Do not share videos to play during the session via screen share (causes choppiness)
   • Instead, use the Upload Videos in Content Tab for pre-recorded content
   • Preview in backstage tab; once live, hosts/presenters cannot see their own screen share (optimizes bandwidth)
   • For Safari browser, the required version is 13 or above
3. Resolution Management:
   • Live Streaming: Automatically downgrades to lower resolution if multiple attendees join or bandwidth drops
4. Co-Host Setup:
   • Before assigning co-hosts from “Stream Options”, map the user as a speaker/attendee in the “People” section, for a seamless collaboration

Video Upload Guidelines

Supported Formats & Specs

• Formats: MP4, MPEG-TS, MKV, HLS
• Resolution: 720p at 30fps (max)
