System Requirements
AJA Video recommends that the Mac Pro or MacBook Pro used with the Ki Pro offer a
FireWire 800 port and support Apple ProRes 422 with a satisfactory level of
performance. Consult Final Cut Pro documentation when setting up and configuring
your system for editing; ensure you have an adequate storage system (RAID array)
and any needed video/audio interfaces.
Apple ProRes 422 Advantages
Data rates:
220 Mb/second Apple ProRes 422 (HQ), 145 Mb/second Apple ProRes 422,
100 Mb/second Apple ProRes 422 (LT), and 36 Mb/second Apple ProRes 422
(Proxy)—all supported by internal system drive or attached storage.
Note: Apple ProRes 422 (Proxy) is for high-quality offline editing at the original frame
size, frame rate, and aspect ratio.
Quality:
Excellent, broadcast quality
Captured media is virtually indistinguishable from pristine uncompressed sources.
Better yet, ProRes maintains the quality during editing, surviving multiple encoding/
decoding generations without degradation. It was designed by Apple for editing,
rather than as a transmission/distribution codec as are most popular codecs. Some of
the advantages include:
Full-size 1920-by-1080 and 1280-by-720 HD resolutions.
Full-size 720-by-486 and 720-by-576 SD resolutions.
4:2:2 chroma sampling. Provides precise compositing and blending at sharp
saturated-color boundaries.
10-bit sample depth. Preserves subtle gradients of 10-bit sources (perfect for
green-screen compositing, graphics or color correction) with no visible banding
artifacts.
I frame-only encoding. Ensures consistent quality in every frame and no artifacts
from complex motion.
Variable bit-rate (VBR) encoding. “Smart” encoding analyzes the image and
allocates more bits to complex frames.
Low data rate requirements make for more storage options and require less
drive space to store high quality video.
Optimized for efficient Real-Time effects
