4K Mode and Image Store
In 4K Mode, images and image sequences imported into the Image Store
cache will be divided into four sub-images, and assigned Image IDs and
descriptions to reflect their association as a 4K image. For example, Image
ID 1000 will load as ID’s 1000, 1001, 1002, and 1003. The image descriptions
will be 1000-1, 1000-2, 1000-3, 1000-4.
CAUTION A tolerance of +/-10% of the width and height of an image is allowed. Stills,
sequences, or movies outside those tolerances will be center cut, the default
for progressive images.
Two Image Store channels are automatically configured as 4K, Image Store
1 and Image Store 5. Each source uses four channels.
Each of the four sub-images must be loaded starting in either Image Store
Channel
1 or Channel 5, then each sub-image in order of Image ID. For
example, Image Store Channels:
• 1/2—1000/1001
• 3/4—1002/1003
•-or-
• 5/6—1000/1001
• 7/8—1002/1003
Importing Images with Audio to Image Store
Images, image sequences, and movies with paired audio (stereo) can be
imported into Image Store cache, and/or saved to disk. The video with
audio must also match the frame rate; 59.97Hz, 50Hz, or 60Hz, otherwise
only the video will be imported.
4K 2SI (2 Sample Interleave) Modes and 2D-DPMs
Three 4K Keyers (Keyers 1-3) are available per 4K ME, up to twelve on a
4-ME switcher. Enabling a 2D-DPM on a 4K key, is the same as in non-4K
modes.
iDPMs are not supported in 4K 2SI mode currently but if used they will rep-
licate the input of sub-image 4. This will have the affect of down sampling
the image to a pixel replicated 1080p image on-screen. This may be suffi
-
cient quality for some uses.
