SVRT: When Can I Use it?
SVRT can be applied to video clips in the MPEG-1, MPEG-2 and DV-AVI
(Type I) formats. In the following conditions, clips (or portions of clips)
do not require rendering during production, and SVRT can therefore be
applied:
• The frame rate, frame size, and file format are the same as those
of the destination production profile.
• The bitrate is similar to that of the destination production profile.
• The TV format is the same as that of the destination production
profile. For more information, see "Set a Video Clip’s Interlacing
Format" on page 57.
If all of the above conditions are met, SVRT can be used. Any clips that
do not meet the above criteria are fully rendered without SVRT.
In the following conditions, clips (or portions of clips) must be rendered
during production, and SVRT can therefore not be applied:
• Adding a title or transition effect
• Modifying the color of a video clip
• Audio profile does not match destination production profile
• Modifying the volume of an audio clip
• Merging two video clips (clips within 2 seconds before or after
the merged clips will be rendered)
• Splitting a video clip (clips within 2 seconds before or after the
split will be rendered)
• Trimming a video clip (clips within 2 seconds before or after the
trimmed clip will be rendered)
• If the total duration of the production is less than one minute
and any portion of the video requires rendering, the entire
production will be rendered for efficiency reasons.
