[edit] Four steps to maximising the audio and video quality in EVO

[edit] Use a Logitech USB Headset

If at all possible, all people involved in the meeting should use headsets:

  • The microphone is positioned very closely to the mouth resulting in much higher audio quality and other participants wont need to strain to hear what is being said
  • Contrary to what some manufacturers claim: echo cancellation devices or inbuilt Webcam mics never sound that good, and other participants will find you difficult to hear (they may even stop listening to you!)
  • Logitech USB headsets are highly recommended

[edit] Have your University open a port in the University Firewall for your computer

  • Have your University open a port (see box below) in the University Firewall for your computer: your network traffic will not be routed by some institutional proxy/NAT and wont have to go through a network 'bottleneck'
  • This ensures that your video and audio communication is transmitted at maximum possible bandwidth
  • The local or institute firewall (if any) should permit communication on the following port for your computer:
Both IN and OUT, Both UDP and TCP: Port Number 46015

[edit] Make sure you are connected to the BeSTGRID_NZ Panda Server

  • (For New Zealand based users)
  • The New Zealand production EVO Panda Server is BeSTGRID_NZ.
  • the Panda server you are connected to is listed in the bottom left of the Koala window.
  • You are automatically connected to the nearest Panda server -- sometime EVO doesn't make the best decision. You should aim to connect to BeSTGRID_NZ.
  • To reconnect to the BeSTGRID_NZ panda choose: Koala menu -> Koala Monitoring. Select "evo.bestgrid.org" from the "Best Panda Servers:" drop-down list, and Click "Connect to Selected Panda".

[edit] Increase the Video Quality and Framerate

  • Assuming you have the necessary port opened in the University firewall (see above) configure your Vievo settings to use the full bandwidth
On the Vievo window, click on Setup...
