The Luma key property is a 6-digit hexadecimal value that is set to #ff2000 by default.

shows the format of the hexadecimal key and how the bits are interpreted.

Table 20. Luma Key Format

0xff

0x20

0x00

With the default value, content with the luma of 0xff is masked (left unchanged), and

content with luma values in the range of 0x00 to 0x20 (the darker pixels) are filtered

from the content and made transparent.

To disable the luma key property globally for all SV-4Ks, leave the value blank (no

spaces). If the Luma key property is blank, then no masking will be applied even if the

option is set on the template.

To modify the default luma key value, complete the following steps:

1. From the Management Dashboard, go to SV Director Configuration > System

Configuration > Global DMP Settings > SV-4K Settings.

2. In the Configuration Property box, find the Luma key property.

3. In the value box, type the 6-digit hexadecimal value beginning with the # sign.

4. Click the disk icon to save your changes.

TIP: You do not need to reset the SV-4K to apply the new value.

Whenever a script starts, the SV-4K media player retrieves the

global settings.
