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.)
