Apple ProRes 422 Advantages

In This Manual

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.
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.
