AMIRA allows you to shoot your images in Log C or Rec 709 video, or with a customized look.
Log C and video are two types of image encodings that usually are found in different production environments.
Rec 709 Video
This encoding delivers images that are ready for display on a computer, video monitor, or digital projector, without any further conversion. If you don't have the luxury of going into creative editing and color correction, shooting Rec 709 video is a good choice.
The term Log C stands for a logarithmic encoding of the high dynamic range scene data coming from the sensor.
The digital numbers in a Log C image are proportional to the exposure measured in stops, which results in a very flat "data curve". Without compressed highlights and blacks, Log C encoding provides much more control over your recorded image. For a visually correct contrast and color representation, however, the Log C images have to be converted to the display color space (e.g. Rec 709 video or DCI P3).
Inside an AMIRA, the sensor data always starts out as a Log C encoded image. Setting the camera to output Rec 709 video turns on a 3D LUT that converts the Log C image to a video encoded image for monitoring or also for recording. The video output can also be customized in the camera, with a set of look parameters. Rec 709 video represents the default video look in the AMIRA.
