ARRIRAW

ARRIRAW delivers uncompromised image quality with maximum processing flexibility for postproduction. It is the highest quality recording format when shooting with the ALEXA, delivering unprocessed 12 bit logarithmic raw Bayer data at native sensor pixel resolution. Any steps that are necessary to create a full color image in a given resolution are performed once the data has been recorded. This provides ARRIRAW advantages in terms of achievable resolution, postproduction flexibility and archivability.


When shooting for a 2K post workflow for example, recording ARRIRAW at 2880 x 1620 pixels and down-converting in post to a 2K image shows visibly better resolution than shooting in 1920 x 1080 HD and up-converting to 2K. This resolution difference is even more pronounced when special effects are involved: the ARRIRAW files can be reconstructed to a 2880 x 1620 full color image for special effects, and only be down-converted to 2K after the effects have been applied.

 

Many processing steps that are irreversibly ‘baked-into’ the ProRes or HD-SDI image on the set are not applied to the ARRIRAW files. Those processing steps will be performed in post, where there is more time and where they can be reversed at any time by going back to the original ARRIRAW files. Thus ARRIRAW provides more flexibility in post, including the flexibility to apply different vendor’s image reconstruction algorithms.
