SVRT: When Can I Use it?
SVRT can be applied to video clips in the MPEG-1, MPEG-2, H.264 (Ultra version
only) 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 "Setting Video Clip Interlacing Format" on page 52.
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.
