‘Avatar’ and ‘Titanic’ will be remastered in High Frame Rate with TrueCut Motion

Vous pourrez bientôt découvrir Avatar et Titanesque sur grand écran en High Frame Rate (HFR) en utilisant une technique spéciale appelée TrueCut Motion pour préserver l'aspect cinématographique.La société de production Lightstorm Entertainment de James Cameron travaille avec la plateforme TrueCut Motion de Pixelworks pour remasteriser "plusieurs titres de films" dont les deux classiques en résolution 4K, HDR (High Dynamic Range) et HFR (High Frame Rate).  - "Nous ramenons AVATAR et TITANIC sur grand écran, plus beaux à tous points de vue,"  dit James Cameron. "Nous présenterons les deux films en 4K avec des visuels à plage dynamique élevée et avons travaillé avec la plate-forme TrueCut Motion de Pixelworks pour remastériser les films à une fréquence d'images élevée, tout en conservant l'aspect cinématographique de l'original."Les détails techniques n'ont pas été divulgués, il n'est donc pas clair si Cameron fait référence à 48 ips, 60 ips ou à une fréquence d'images encore plus élevée telle que 120 ips.

Le HDR a besoin du HFR

Pourquoi? Les niveaux de luminosité plus élevés du HDR rendent le tremblement inhérent au contenu plus visible pour le spectateur. Combiné à une vitesse de panoramique élevée, le tremblement peut devenir trop répandu et gênant.

Judder Equivalence vs. Luminance for Various Camera Pan Speeds

Ultra-fast displays such as OLED can make it even worse, creating a type of stroboscopic effect as discussed in FlatpanelsHD's in-depth TV reviews. Pixelworks' TrueCut Motion platform aims to solve the issue by letting filmmakers working with content in frame rates beyond 24fps adjust judder, motion blur and frame rate appearance on a scene-by-scene basis during post production in order to retain the cinematic look and avoid the soap opera effect.
TrueCut Motion technology provides filmmakers with a visual palette of cinematic motion looks that goes beyond anything previously possible. While motion pictures have seen tremendous improvements in picture performance, with higher resolution, higher dynamic range and more colors, the motion look has remained unchanged for close to a hundred years. TrueCut Motion technology allows filmmakers to dial in the motion, with any source frame rate, shot by shot, in post-production. The TrueCut Motion platform then ensures that these creative choices are delivered consistently across every screen, whether in the theater or the home.

Avatar 2 in HFR?

James Cameron did not comment on his approach for the upcoming Avatar movies but it is possible that the two remasters are part of a bigger project. Pixelworks believes that more filmmakers will want to take advantage of its HFR technology once they have seen the remastered versions. - "Lightstorm is once again extending the boundaries of the cinematic experience, and we are ecstatic to be a part of that," said Richard Miller, GM of TrueCut at Pixelworks. "After experiencing these remastered versions of AVATAR and TITANIC, we believe more and more filmmakers will be excited to take advantage of motion grading with TrueCut Motion technology."
