When a clip recorded in Rec 709 (with or without a Look File baked in) is
played back, no Look File will be applied by the camera during
playback. For the duration of that clip, Look Files will be disabled.
CDL Server Connection
When internal recording is set to ARRIRAW (only available on ALEXA
XT cameras and ALEXA Classic cameras with an XR Module upgrade),
it is possible to configure a CDL server connection instead of using an
ARRI Look File. With a CDL server connection enabled, the ALEXA will
retrieve the CDL information from the CDL server at the beginning of
each recording and store the values in the clip metadata. Additionally,
the ALEXA retrieves the CDL information at the end of each recording
to update the CDL values in case they have been modified during the
shot. The values from the beginning of the shot, however, are still
accessible during offloading as "old" values. Due to technical
limitations, however, it is not possible to directly apply CDL values in
the ALEXA to outputs or recorded material.
To configure a CDL server connection:
1. On the LOOK FILES screen, select CDL CONF.
2. Enter the IP address of the CDL server.
Note: The CDL server must be located in the same /16 subnet as the ALEXA.
Therefore the first two parts of the IP address cannot be changed.
Note: The CDL server must be reachable at port 6666.
To activate/deactivate the CDL server connection:
On the LOOK FILES screen, press CDL.
When the connection to a CDL server is activated, it is no longer
possible to select an ARRI Look File or apply it to outputs. The gamma
settings for the individual outputs are still available.
