What is? ARI File Format?
Developed by ARRI, a German firm producing cameras and lighting equipment, ARI, short for ARRIRAW, is a file format for digital cinematography and television production. The ARRIRAW picture format differs from a compressed format in that the data kept in the file is not compressed; it is uncompressed. Consequently, the ARRIRAW technique generates images of a much better quality. The basis for the ARRIRAW format to be used is the Bayer pattern, which uses a mosaic of red, green, and blue filters to gather the whole spectrum of color information.
The ARRIRAW format helps one to capture and save the whole spectrum of 16-bit visual data from an ARRI camera. This data collection incorporates not only the color information but also the linear and logarithmic light values. The camera guides the data about the image to either save in a 10-bit or 12-bit format. Being a proprietary format, there is no other camera system that fits the ARRIRAW format.
Several applications exist that allow ARRIRAW files to be opened. Among these offerings are Apple Final Cut Pro, Adobe Photoshop, and Adobe After Effects. Certain programs may have to have extra plugins or codecs installed in order to open ARRIRAW files. Furthermore, some cameras could need a further plugin to be accessible in order to save data in the ARRIRAW format.
Regarding television production and digital cinematography, the ARRIRAW format is becoming increasingly well-known. The image is of exceptional quality, and the fact that the data has not been compressed ensures that it will remain independent of the degree of post-production modification applied to it. Furthermore easily worked with, the ARRIRAW format is compatible with a great range of well-known software tools.
