CHP. 6 WORKING WITH EVENTS

3. Click Re-calculate to normalize the event again.
Tip: You can set the maximum decibel level used by Vegas to
calculate the event during normalization. For more
information, see Audio tab on page 266.
Maintain aspect ratio (video only)
Video and image files of various sizes and formats can be included in a single project. The project itself may
have a different frame size aspect ratio from the source media files. This is not a problem, but you must
specify how Vegas handles these differences. If the length-to-width ratio of the source media and the
project’s frame size are the same (e.g., 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 may become distorted (stretched or
compressed). By maintaining the aspect ratio of the original, Vegas keeps the video 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 may see flickering or crawling edges if this switch is not applied.
Resample (video only)
Resampling allows Vegas to interpolate frames in an event when the frame rate of a media file is significantly
different from the project’s frame rate. Resampling may solve some interlacing problems and other jittery
output problems. For more information, see Resampling video on page 175.
Vegas provides three options for event-level resampling:
•
Smart resample: Vegas 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: Vegas always resamples the event, regardless of its frame rate or the project’s frame rate.
•
Disable resample: Vegas does not resample the event.
The BMP media file in this
example is 320x100, while the
project is set to 320x240.
