Appendix C: Technology Overview

Analog vs. Digital

With repeated use, the magnetic tape used in High-8, 8 mm, VHS, and S-VHS
becomes prone to wear and tear. It gets thinner and thinner until the video could
no longer be played. On the other hand, the quality of digital video doesn't
diminish over time. You can play DVs countless times and still expect the quality to
be as sharp as it originally was. Digitization also extends a video's life span and
allows you to enhance its original sound and picture quality.
Digitizing analog videos is a breeze with VideoStudio, wherein data captured from
an analog device are automatically converted to digital format. Once digitized, you
can edit these footage and output them in any disc format of your choice.
Footage can be captured from your analog source and digitized for editing in your PC

HD Technology

HDV users are by definition concerned with picture quality. VideoStudio allows you
to work with high definition videos just as you would with DV: batch capture, edit,
apply filters and transitions, then output to various formats such as SD, HD or
WMV-HD for Web-sharing.
After you have connected an HDV camcorder and properly set up the device for
capturing, VideoStudio will automatically set the capture plug-in and device control
to HDV Capture Plug-in and HDV 1394 Device Control respectively.
The HDV Capture Plug-in converts the source video from your HDV camcorder into
an MPEG-2 Program Stream (PS) video file when capturing it into your computer.
By converting the video, it allows you to take advantage of VideoStudio's
SmartRender technology when you edit the captured video clips. This means that
whenever you preview your edits or create a video file, only the clips which have
been altered will be rendered.
