... When capturing and digitizing video, the following components are critical:

Resolution—The horizontal and vertical dimensions of the video session. A full-screen video session is typically 640 horizontal pixels by 480 vertical pixels. Full-screen video uses these dimensions because it yields the 4:3 aspect ratio of standard television. Of the 525 vertical scan lines in the NTSC standard, 483 lines are used to display video. The other lines are used for signaling and are referred to as the vertical blanking interval. Because the NTSC standard uses 483 vertical lines, capturing at 640 by 480 means that three lines are dropped during the

digitization process.

Color depth—The number of bits that are used to express color. At the high end is 24-bit color, which is capable of displaying 16.7 million colors and is the aggregate of 8 bits of red, 8 bits of green, and 8 bits of blue. The 8 bits are used to express color intensity from 0 to 255. Other common color depths are 16-bit and 8-bit, which yield roughly 65,000 and 256 colors,

respectively.

Frame rate—The number of frames that are displayed per second. To deliver NTSC-quality video, 30 frames per second are displayed. PAL and SECAM display 25 frames per second.
