Treasured's Movie Repair Guide -- ARRIRAW

ARRIRAW is a RAW digital cinematography format, used in some ARRI cameras.

ARRIRAW retains the camera's natural color response and great exposure latitude as uncompressed and unprocessed sensor data. With the introduction of the ALEXA XT series, ARRIRAW data can be recorded directly in the camera, without the need for an external recorder.

Working with ARRIRAW

ARRIRAW footage is stored as a clips inside a folder, being each frame a .ari file.


Treasured (since version 3) can detect ARRIRAW footage in recovered files (regardless of extension), in cards and in hard disks.
For preview, please verify if you have installed the necessary software.

Each frame corresponds to an .ari file. The collection of frames inside a folder corresponds to a clip.
