Cooke /i Technology


Cooke’s /i Technology enables film and digital cameras to automatically record key lens and camera data for every frame shot and provide it to post-production teams digitally. It streamlines production and post, saves time and cost, and eliminates guesswork while enabling greater creative freedom.


Using i/ Technology Means. . .

You can have a continuous remote readout of the precise focus setting, T stop and depth-of-field from electronics inside the I equipped lens so you will be able to see the actor in front of you and the focus setting on the lens beside you without turning your head or even having to move your eyes too much. ACs love it.

  • You can digitally record vital lens and camera settings accurately, frame-by-frame, all synced to Timecode, instead of having to manually write down lens settings for every shot, eliminating human error. One task your script supervisor needn’t worry about.
  • Normal operations on set are not affected. Metadata recording takes place without having to monitor or manipulate anything. Data records to digital or film recording medium or to an SD card. No specialists required on set and the DP needn’t worry about fussing with complicated accessories.
  • You will streamline the production and post production processes to save time and cost while ensuring a better quality product because the digital data you can now provide takes the guess work out of the process. Artists create visual effects and 3D models that are more accurate, with much greater speed. Everybody wins -- ACs, DPs, Directors, Producers, VFX Artists – EVERYBODY wins.

Cooke's I "Intelligent" Technology enables film and digital cameras to automatically record key lens and camera data for every film frame, which can then be provided digitally to post-production teams. The technology streamlines both production and post, saving significant time and costs and eliminating guesswork, while enabling greater creative freedom. I Technology is standard on all new Cooke 35mm lenses: S4/i, 5i, Anamorphic and miniS4/i by Cooke lenses.

"This technology represents the essence of forward compatible, forward thinking metadata support. Open source, anyone can use it, high degree of accuracy. Ten stars out of a possible five for providing for the digital future of cinematography. Bravo!"
David Stump, ASC, DP/VFX Supervisor

"The use of this data provides more accurate results in faster time and removes yet another element of uncertainty from the set-to-post information transfer process. Its use will allow more complex shots to be completed and will also allow new types of shots."
Michael Lancaster, product director, The Pixel Farm, www.thepixelfarm.co.uk

Continuous Remote Readout

With the Cinematography Electronics I Lens Display Unit you can have continuous remote readout of the precise focus setting, T stop and depth-of-field from electronics inside the I equipped lens. Focus Pullers will be able to “see” where the actor is relative to lens focus and depth of field without turning their heads by using Cinematography Electronics' I Lens Display Unit in conjunction with their Cinetape.  Using Transvideo's CineMonitorHD with its built-in I Technology, focus pullers can see a graphic representation of the iris, focus and depth-of-field along with the outstanding picture quality the monitor provides.

Record Vital Lens and Camera Settings

Manually writing down lens settings for every shot is now passé. Focal length, focus distance, f-stop, frame rate – vital camera and lens settings are digitally recorded for every frame, at any frame rate up to 285 fps, film or digital, and stored as metadata.

Digital cameras that are I equipped (ARRI Alexa, RED, SI 2K, Sony F55, F5, F65, F35, F3) and film cameras (Aaton Penelope, Arricams) talk to I lenses directly via contacts in their lens mounts. The I Technology provides the framework; the extent of camera data made available is the choice of the camera manufacturer via their software and software upgrades.

Post Production

Metadata is passed through to post-production to improve VFX creation and DI calibration. Post production artists can sync the lens data to the 3D camera data to produce a more natural looking 3D model of the shot significantly faster than using traditional manual processes and guesswork.

Improve Accuracy & Speed

"By having access to lens metadata, the PF Track software came up with a solution an order of magnitude faster than by its algorithms alone, and the result was much more accurate because it was based on real camera data. This workflow brings production and post infinitely closer and benefits both artistic quality and production time."
