result, the image holds as much dynamic range information as possible, without using
Log C encoding. Highlight and shadow detail that would be lost in the typical REC 709

Playback and ARRI Look File 2 files
During playback, the camera makes a distinction between clips recorded in
ARRIRAW, Log C, or Look processing.
When a clip recorded in ARRIRAW or Log C is played back and an output is
configured for Look processing, the look will be applied to this output. Please note
that this is the currently enabled ARRI Look File 2, as the camera does not take into
account which ARRI Look File 2 was active when the clip was recorded. It is the
responsibility of the user to make sure the correct ARRI Look File 2 is applied during
playback.
When a clip recorded with Look processing is played back, no ARRI Look File 2 will be
applied by the camera during playback. For the duration of that clip, ARRI Look File 2
files will be disabled.
