Accessing event properties
The properties of an event are automatically determined based on the properties of the source media file. In addition to the event switches (mute, loop, etc.) described in the previous section, event properties include playback and undersample rates for video and pitch shifting for audio.
1.
2.From the shortcut menu, choose Properties. The Properties dialog appears.
The first tab in the dialog, either Audio Event or Video Event, contains the properties that are exclusively related to your Vegas project. The second tab, the Media tab, contains many properties that are an inherent part of the media file itself.
In addition to the event switches discussed in this chapter, event properties on the Audio Event/Video Event tab include the following:
•For video events, the Playback rate box sets the rate of playback. For example, a playback rate of 1 plays at normal speed, while a playback rate of 0.5 plays at half speed. For more information, see Time compressing/ stretching events on page 129.
•For video events, the Undersample rate box allows you to simulate a lower frame rate. For example, an undersample rate of 0.5 plays the event at half its original frame rate. Each frame plays twice as long as in the original media file, creating a strobe effect.
•For audio events, the Time stretch/pitch shift section of the dialog allows you to change the pitch, duration, or both pitch and duration of an audio event. For more information, see Pitch shifting audio events on page 127.
Adjusting audio channels
A stereo audio event has two channels: right and left. You can adjust how these channels are played by right- clicking an event, choosing Channels from the shortcut menu and choosing one of the following commands from the submenu:
•Both plays both channels in stereo. This is the default setting.
•Left Only plays only the left channel. Playback is mono and is centered between the two channels.
•Right Only plays only the right channel. Playback is mono and centered.
•Combine adds the two channels into a single channel and divides the level in half to prevent clipping. Playback is mono and is centered between the two channels.
•Swap exchanges the right and left channels (stereo playback).
You can also pan from one channel to the other using either the multipurpose slider or a pan envelope. For more information, see Adjusting stereo panning on page 145.
