Shooting the Live Presentation

From within an embedded “reference movie,” you can direct client players to on-demand presentations encoded for different connection speeds to give users the best possible viewing experience.

For instructions on creating a web page with links to streamed media, see “Setting Up a Web Page With Streamed Media” on page 32.

Shooting the Live Presentation

If all the preparatory work has been done, as outlined above, and the equipment and connections have been thoroughly tested, shooting the live presentation should be straightforward.

Here are a few tips for avoiding problems during the event:

mOn the day (or evening) of the actual event to be streamed live, set up early so you have time to check once again that all components are working as expected.

mIf an audience is to be present, let them know in advance that you will be webcasting the presentation live and ask for their cooperation.

mTape down any cables strung along the ﬂoor to minimize tripping hazards.

mCheck for potential sources of extraneous noise and take abatement measures if possible.

Archiving the Live Presentation

In the example setup, the iMovie application that comes with Mac OS X is available on the laptop. iMovie is used to import the recorded DV footage from the camera tape and then to encode and archive taped live presentations after they have occurred.

To archive a live presentation, ﬁrst import the recorded DV footage.

1Connect the DV camera to the laptop using FireWire and turn on the camera.

2Insert the tape with the video footage to be archived into the camera and switch to VTR mode.

3Open iMovie on the laptop and in the iMovie UI set the Mode Switch under the iMovie monitor to Camera mode by dragging the round blue slide toggle toward the DV camera icon.

4Use the Camera mode playback controls to view a portion of the tape in the iMovie monitor. If the tape doesn’t play, check the connections and make sure the camera is turned on.

5Rewind the tape to a few seconds before the point where you want to start importing.

6Click Play below the iMovie monitor.
