The video-in capabilities of the Quadra 660AV and 840AV support full-motion, full-screen viewing of any video material in the NTSC, PAL, or SECAM format. The video subsystem is completely independent of the CPU or DSP. One of the features provided by this subsystem is the ability to record a quarter screen image at 10 to 20 frames per second directly to a hard disk in real-time without data compression.
Video-in provides for on-screen viewing of video materials, 24-bit frame capture, and QuickTime movie recording without additional hardware.
