Скачать или смотреть Brainstorm 60FPS / HDR upsampling demo - "Knock my socks off"

This is a second test of an attempt to re-create a mixed frame rate version of Douglas Trumbull's vision for Brainstorm using a small portion of the film. This version combines frame interpolation in the "hyper-real" shots with a touch of HDR to create a bit more "pop" in those dramatic scenes.

It was Trumbull's vision to shoot Brainstorm in Showscan, an early version of HFR (high frame rate) cinema. Unfortunately, due to the limitations of theatrical equipment at the time and the prohibitive cost of retrofitting them to play Showscan, this vision was never realized, and Brainstorm was instead filmed and released in traditional 24p.

Although Trumbull's R&D tests of Showscan were at 72fps (3X the speed of 24p) I have only upsampled the footage to 2.5X, which is 60p which can be played on YouTube. The point of this exercise is to see something approximating what Trumbull envisioned, so please make sure you watch this clip at 60fps (and HDR if possible) for the desired effect.

Trumbull left clues in the editing about which parts were intended for high frame rate. In regular 24p scenes, the frame was cropped to a 4:3 frame and pillarboxed, but the cuts meant for Showscan were filmed in wide screen 2.35:1 (and usually with a wide angle lens).

Software and upsampling technique used:
The original film was placed into an Adobe Premiere Project. The footage was then placed onto a 59.94 FPS timeline. Select edits were identified, cut and placed onto a new layer, and upsampled using Optical Flow time interpolation.

It necessary to make sure the interpolated clips were not cut on an original edit boundary, and instead each interpolated clip was given "handles" of 1-2 frames to ensure that Optical Flow did not try to interpolate between two scenes.

HDR and grading was added in DaVinci Resolve.
