of 1.302083 MB per image equivalent to a sustained data rate of

250 Mbit/sec. as specified as the maximum data rate by the DCI.

In detail the window to configure the JPEG2000 encoding provides the

following settings items:

Further information about color space conversions can be

found in section “Color Space Conversions” on page 6-1.

Color Space

Interpretation

This setting determines the color profile and inter-

pretation of RGB video material:

– When converting from RGB to another color

space (material in timeline is RGB, finalized

output format is set to another color space), it

sets the color profile of the source material, i.e.

of the material in bin and timeline.

– When converting from another color space to

RGB (material in timeline is in another color

space, finalized output format is set to RGB), it

sets the profile of the target material, i.e. of the

material to be finalized and rendered.

– When converting from RGB to RGB (1:1 con-

version) or when no RGB material is involved

in the color space conversion, this setting has

no effect.

The timeline material is handled clip-wise,

meaning each clip in the timeline is evalu-

ated separately and converted with re-

gard to its color space.

Rate Control For maximum efficiency CLIPSTER encodes the im-

age data with a variable bit rate (VBR). This setting

enables the post compression rate control, i.e. it

determines the maximum file size (in megabyte)

that one image file may provide after encoding.

Thus in turn, it determines the maximum bit rate

(data rate). To calculate the file size from a given

bit rate use the following formula:

With the check box in front of this setting you can

turn off the rate control. Once deactivated the im-

ages will still be compressed and encoded with

VBR but use the maximum possible files size (e.g.

between 2 and 3 MB for 2K images).
