Creating Digital Video movies with
WinTV-USB
Overview of Video Clip Capture
Live video which is digitized by the video digitizer (see “How WinTV USB works”) can be “captured” as a video sequence (or “video clip”) by using the WinTV Capture program. This program is provided in the WinTV Application and uses Microsoft’s WDM for Windows capability which is built into Windows 98 and 2000.
WinTV USB gives high quality captured video by storing uncompressed digitized video in an AVI file. This compares with compression methods such as JPEG and MPEG, where some loss of video quality is accepted in order to reduce the amount of data stored. Uncompressed video capture creates high quality digital video movies, but requires optimized system performance to avoid lost video frames (called “dropped frames”.)
To create the best quality digital videos, use the following steps:
•Compress/Edit, etc. by using the appropriate 3rd party software with these functions
•Edit the raw video. Add special effects, cut, paste, etc. using one of the popu- lar digital video editing programs such as Adobe Premiere, MGI VideoWave or
•After editing the video, compress the video for the playback target. For exam- ple, if you are creating a video to be used in a multimedia presentation, com- press with either Intel’s Indeo or Supermac’s Cinepak. If you are creating a
