68 Chapter 6 Setup Example

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:

• On the day 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.

• If an audience is to be present, let them know in advance that you will be

webcasting the presentation live and ask for their cooperation.

• Tape down any cables along the floor to minimize tripping hazards.

• Use a directional microphone or a live audio feed if at all possible.

• Check for potential sources of extraneous noise and take abatement measures

if possible.

Archiving the Live Presentation

In the example setup, the iMovie application, which comes with Mac OS X, is 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.

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

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

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

3 On the laptop, open iMovie and set the Mode Switch under the iMovie monitor to

Camera mode (drag the round blue slider toward the DV camera icon).

4 Use the 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.

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

6 Click Play below the iMovie monitor.

7 Click Import when you see the point in the presentation where you want to start

importing.

8 Click Import again when you want to stop importing.

9 If you get some footage that you don’t want to include in your archived presentation,

you can edit it later using iMovie.

Important: You’ll need to monitor hard disk space as you import video and create your

iMovie. One minute of DV footage uses about 220 MB of hard disk space, so a one-hour

presentation can use up more than 13 gigabytes of disk space. The Free Space status

bar, below the clip shelf, shows how much disk space is available at any point in the

import process.
