3. Click Re-calculate to normalize the event again.
Maintain aspect ratio (video only)
Video and image files of various sizes and formats can be included in a single project. The project itself can have a different frame
size aspect ratio from the source media files. This is not a problem, but you must specify how these differences are handled. If the
length-to-width ratio of the source media and the project’s frame size are the same (for example, source media at 320x240 and
project frame size of 640x480), no aspect ratio distortion occurs. If the ratios are not the same, the source material might become
distorted (stretched or compressed). By maintaining the aspect ratio of the original, the video is kept from becoming distorted by
letterboxing or pillarboxing around the edges. This is the default setting.
Reduce interlace flicker (video only)
This switch can be useful in cases where the source material didn’t originate as video and contains extremely high spatial or
temporal frequencies. When you watch the rendered (interlaced) output on video of this sort of media, you might see flickering or
crawling edges if this switch is not applied.
Resample (video only)
Resampling allows Vegas Pro software to interpolate frames in an event when the frame rate of a media file is significantly different
from the project’s frame rate. Resampling can solve some interlacing problems and other jittery output problems.
For more
information, see Resampling video on page 277.
Three options are provided for event-level resampling:
• Smart resample: Only resamples the event when the event frame rate does not match the project output frame rate. This can
occur either because the event has a velocity envelope or because the frame rate of the original media is different than the
project frame rate. Smart resample is the standard setting.
• Force resample: Always resamples the event, regardless of its frame rate or the project’s frame rate.
• Disable resample: Does not resample the event.
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. Right-click an event to display a shortcut menu.
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 Pro
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 107.
• 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 105.
Tip: You can set the maximum decibel level used to calculate the event during normalization. For more information, see Audio tab
on page 425.
