System Performance Considerations When Using TARGA 3000
You should be aware that there are a number of hardware considerations that can influence
your video recording ability. Some involve the speed at which you can capture video
frames while others affect image quality.
The primary criteria for evaluating your system is its ability to keep pace with the stream
of data, both video and audio. For uncompressed video such as RGB 32 or YUV, an
NTSC resolution of 720 x 480 pixels represents a total of 307,200 pixels. At 29.97 (or 30)
frames per second, that’s 9,216,000 pixels per second. At 32 bits per pixel, that’s
approximately 36 to 37 megabytes per second (if audio is included then the data rate can
increase by up to 192K per second). Therefore, a high-performance SCSI controller with
10,000 or better rpm ultra-2 wide drives, or a SCSI 160M, is essential in order for you to
achieve the necessary data rates for optimal results.
