KPU-Shelf

Ki Pro Ultra can be mounted side by side using the optional KPU-Shelf for
rackmount applications. Using the four channel HD recording capability and front
panel quad display, two rack mounted Ki Pro Ultra units can record and monitor
eight HD signals in only two rack units of space.

Apple ProRes 422 and Apple ProRes 444 Advantages

Captured media using Apple ProRes 422 or Apple ProRes 444 is virtually
indistinguishable from uncompressed HD/2K/4K sources. Better yet, Apple ProRes
maintains the quality during editing, surviving multiple encoding/decoding
generations without degradation. It was designed by Apple specifically for
editing. Some of the advantages include:
• Resolution support for 4096-by-2160 (4K), 3840-by-2160 (UltraHD), 2048-by-
1080 (2K), 1920-by-1080 (HD), and 1280-by-720 (HD).
• 4:2:2 or 4:4:4 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.
NOTE: Ki Pro Ultra can accept 12-bit inputs but processes and encodes at 10-bit.
• Intra-frame 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.

Avid DNxHD/HR Advantages

Quality using Avid DNxHD and DNxHR is excellent— high quality encoding
without high bandwidth requirements. Avid DNxHD and DNxHR were designed
for non-linear post-production and broadcast to withstand multi-generational
processing.
• Full-size 4K, UltraHD, 1920-by-1080 and 1280-by-720 resolutions.
• 4:2:2 chroma sampling.
• 10-bit sample depth (DNxHR HQX or DNxHD HQX), or 8-bit.
NOTE: Ki Pro Ultra can accept 12-bit inputs but processes and encodes at 10-bit.
• Every frame of encoding is independent.
• Constant bit-rate (CBR) encoding.
• Low data rate requirements.
