6. What is SVRT/SVRT II and when can I use it?
SVRT (Smart Video Rendering Technology) is a proprietary
rendering technology from CyberLink that intelligently
recognizes which portions of a movie clip have been modified,
and only renders those portions - not the entire video clip -
during production. Rendering only the modified portions of a
video clip saves time and preserves the original quality of the
video. Using SVRT, PowerDirector renders MPEG-1, MPEG-2,
and DV-AVI video faster than any other software on the market.
(Other video editing software programs have to render the entire
video even if one single frame has been modified!)
SVRT II further breaks movie clips into their component video
and audio parts, then renders only the audio or video portion
that has been modified. This further reduces the amount of time
needed for production!
CyberLink’s Smart Video Rendering Technology is available
during production when the frame rate, frame size, and file
format of video files in your movie are the same (and bitrate is
similar). In this case, SVRT is used to render these files. If any
clips do not meet the above criteria, they are fully rendered
without SVRT.
If you have previously produced a disc using SVRT and the disc
encountered compatibility issues with your player, render the
video again without using SVRT. (Some players are unable to
play back MPEG video with a modified GOP pattern.)
7. What is “editable DVD”?
Editable DVD is to make your authored DVD able to be further
edited even when it's already burn on a disc. By applying this
technology, you will be able to record your DVD quickly and
you will also be able to append new videos, change backgrounds
later when you finished it. Editable DVD is 100% compatible
with your DVD player.
