ALEXA MINI
L’ALEXA MINI est la dernière des caméras Arri, mini par la taille pas par les performances. Toujours fidèles à leur réputation, les ateliers Arri ont miniaturisé leur légendaire caméra numérique, offrant à leur gamme ALEXA un model plus compact, capable de s’opérer sur un drone ou sur un gimbal. Elle offre des performances incroyables pour ce type de caméra, proposant jusqu’à 200fps et différents codecs d’enregistrement dont le ProRes 444XQ.(Licences ARRIRAW et Anamorphique 4/3) Livrée avec : Caméra

Avez vous besoin de batteries Vlock supplémentaires et de carte mémoire en plus? L’ALEXA MINI bénéficie entre autres du même capteur que ses grandes sœurs de dernière génération, réputées pour un rendu des peaux incomparables. Beaucoup d’opérateurs préfèrent tourner avec les ALEXA par rapport aux RED, notamment pour des questions de rapidité de tournage et de simplicité. L’ergonomie des caméras ARRI proposent un accès rapide aux réglages, diaph, iso, framerate… L’ALEXA MINI a été doté d’un jeu de filtre ND gérés électroniquement, 0.6, 1.2, 2.4. Elle est contrôlable à distance par wifi et embarque un système de contrôle des moteurs C-force en façade sans utiliser de récepteur.

DEBAYERISATION The sensor in the ALEXA is covered with a mosaic RGB filter pattern, called the Bayer pattern. When an exposed frame is sampled by the sensor, it is captured as a one-channel image (as opposed to a regular RGB three-channel color image). The reconstruction of the missing color components for each pixel, based on the type and position on the Bayer pattern is called de-bayering. With a Bayer pattern sensor, 50% of the sensors photosites are used to represent green, 25% of the photosites represent red and the remaining 25% represent blue. The different ARRI De-Bayer Algorithms (ADA) control how the color channels are reconstructed.- ADA-5 HW is the lastest de-bayer algorithm used in the ALEXA cameras starting with SUP 11.0. It offers improvements for bluescreen vfx shoots and reduces noise as well as aliasing.
- ADA-5 SW is an enhanced software de-bayering algorithm based on ADA-5 HW
- ADA-3 HW is the camera hardware de-bayer algorithm used in ALEXA cameras in SUP 7.0 up to SUP 10.0.
- ADA-3 SW is an enhanced software de-bayering algorithm based on ADA-3 HW. Depending on the scene content, it can deliver more image detail than ADA-3 HW.
- ADA-2 SW is a legacy software de-bayer algorithm.
- ADA-1 HW is a legacy camera hardware de-bayer algorithm, that was used before SUP 7.0.
