Instructions for creating a webcast

What is a webcast?

A webcast is web broadcast, a presentation over the Internet. It's similar to a classroom presentation with the difference that the presenter and the attendees can be in different locations.

A webcast can be seen in two ways: live or on-demand.

Terminology

  • Presentation: audio and video, showing the screen and the voice of the presenter
  • Remote recording: The Presenter and the Operator are on two different computers.
  • Local recording: The Presenter and the Operator are the same person.
  • Presenter: The person who shows the presentation
  • Attendee: Everybody watching the presentation.
  • Operator: The person who operates the g2m control panel: start recording, pause recording, mute, etc.
  • g2m: software service that is used in this article for remote presentations, see www.gotomeeting.com
  • Live webcast: A live webcast is seen by the attendees at the same time that the presenter is presenting. A day and time for the live webcast is announced, and they all connect to the presentation at the same time.
  • On-demand webcast: An on-demand webcast is a recording of a previously shown live webcast, see examples.

Requirements

Requirements to be a Presenter/Attendeed/Operator of a live webcast:

  • A computer with Windows XP/Vista with a broadband Internet connection
  • The operator needs to provide a g2m login, it's paid, but they provide a free trial
  • The presenter needs to have a headset with microphone
  • The presenter needs to have a headset, optionally with a microphone
  • To preserve the quality of the audio, please do not use hardware that is labeled 'Fair' or 'Poor' in this table.
  • The only software tool needed is g2m

Requirements to be an attendee of an on-demand webcast

Any headset of speakers can be used. Also any type of internet connection can be used, if its a slow connection the webcast will take longer to download.

On-demand webcasts can be viewed at any moment, at the convenience of the attendee. It may be stopped, paused, or rewinded.

Since on-demand webcasts have less requirements than live webcasts, most webcasts viewings are done on-demand.

Steps for recording a webcast

The following steps are for recording a live webcast, and the resultant product is an on-demand webcast, a .wmv file with video and audio.

Presenter and operator configure their computer

Before a live webcast, presenter and operator need to configure their computer.

Set screen resolution to 800x600 (Presenter)

It's recommended to use a low resolutions such as 800x600, otherwise the resultant recording may be difficult to read, the fonts may be show to small.

Right-click on the Windows desktop, select 'Properties' > 'Settings'. Set the screen resolution to 800x600 pixels:

Start g2m session and set audio mode (Operator)

A few minutes before the live webcast scheduled time, the operator starts the g2m session. The g2m control panel will show:

In the g2m control panel, under 'Audio Mode' select 'Use Mic & Speakers'. This operates similar to Skype, all attendees with headsets connected to their computer will join a teleconference. A microphone is optional for attendees, if they want to ask questions verbally during the Q&A part of the presentation.

Show screen (Operator and Presenter)

If using remote recording, in the g2m control panel the operator selects 'change presenter' and switches to the presenter. The presenter will see a prompt 'show my screen' and accepts it.

The presenter opens the application to be shown during the presentation (for example a GIS), and maximizes it so that it covers the desktop.

In the g2m control panel the presenter selects Screen > Show only > Screen-CLEAN:

Set recording preferences (Operator)

In the g2m control panel select File > Preferences > Recording, and set as follows:

Under 'Save in' you can select any local folder on your computer.

Record the presentation (Operator)

The operator presses the 'Mute All' button, so only the presenter's voice will be heard during the main presentation. If at the end there is a Q&A session during which the attendees may ask questions, the operator can unmute them.

The operator presses the 'Start Recording' button. Note: if this button is not visilbe select View > Recording.

The 'Stop Recording' pauses the recording, which can be resume by pressing 'Start Recording'.

When the presentation ends the operator closes the g2m session, and a .wmv file will be automatically saved in the 'save in' folder indicated under 'recording preferences', see above. This .wmv file can be viewed using Windows Media Player
