Extron Electronics JPEG 2000 Encoder - Manual (Page 18)

Encoding parameters
Use the Encoding Parameters section of the Encode Settings tab to define the properties
of the DCP.
The available settings include:
z
Resolution — Choose an output resolution. The drop-down list displays formats that
correspond with the JMP 9600 hardware profile selected from the
Options menu.
z Chroma — Choose the chroma setting.
TIP: When 4:4:4 color sampling is selected, the resulting clip requires the JMP 9600
to be configured for single channel mode.
z Frame Rate — Choose a frame rate. The drop-down list displays formats that
correspond with the JMP 9600 hardware profile selected from the
Options menu.
z
Bit Depth — Choose a bit depth (bits per channel).
TIP: 12 bits per channel is recommended.
z Colorspace — Choose a colorspace.
TIP: Select None when encoding for applications (such as Digital Cinema) using
XYZ colorspace. The values are passed through without conversion. Otherwise,
select
ICT to create sRGB, RGB, or YCrCb colorspace files.
z CBL (Code Block) Size — The default (32, 128) is not adjustable unless:
z
Resolution is set to 720p and chroma is set to 4:4:4
z
Resolution is set to 1080p and chroma is set to 4:4:4
z
Resolution is set to 2K and chroma is set to 4:4:4
If any of these settings are selected, you can choose between 32, 188 and 32, 32.
z
Target Mbps — Set the target bit rate.
TIP: The default (suggested) values are 125 Mbps for 4:2:2 files and 250 Mbps for
4:4:4 files.
To adjust the settings:
1. Click the button for an available setting. This displays the drop-down list of options.
NOTE: Available settings depend on the JMP 9600 hardware profile that is set in
the Options menu (see “ JMP 9600 Hardware Profile ”).
2. From the drop-down list, select the desired option.
