XT2 Series DISK RECORDER – Version 10.05 - Software Technical Reference

Important

Some video formats allowed on XT2+ hardware create clips that are not

compatible with previous hardware. When an incompatible format is

selected, a warning will be issued at the starting up of the application. In

addition, the video format information displayed on the Shift-F2 page of

the Multicam indicates any incompatible information.

VIDEO DISK BLOCK SIZE

[8 MB]

This parameter indicates the size (in KB) of data blocks to be recorded to or read

from the disks.

OPERATIONAL DISK SIZE

Range: [0…100]

This parameter indicates the percentage of the disks actually used to store the

data. Restricting access to the centre part of the drives increases the performance

of the system but decreases capacity.

REC HD-> SD LOW LATENCY

Possible Values: Off / On

This parameter prevents the downconverted output of the record channels from

being delayed. This is very useful in setups including high resolution and low

resolution servers.

VERTICAL INTERPOLATOR AND FOUR LINES INTERPOLATION

Possible values: Off / On

This parameter enables or disables the interpolation processes. Select off to

disable the interpolation process, or on to enable the interpolation process

selected by the Four lines interpolation parameter. An interpolation process is

aimed at reducing the vertical jitter of the pictures that is present during slow-

motion replays.

This vertical jitter is actually caused by a violation of the frame parity when

playing back the pictures at less than 100 % speed.

The process consists in re-building new frames to produce a more transparent

result. These frames have to be interpolated - that is calculated by making

suitably weighted averages of adjacent lines. There are 2 interpolation modes: the

2-line interpolator and the 4-line interpolator. The disadvantage of this method is

that it reduces the vertical resolution. This is particularly true with the 4-line

interpolator.
