Overview
Powerful Control of Texture and Time
ARRI Relativity™ is a powerful suite of software tools that offers fast, efficient and interactive control of texture and time using sophisticated motion estimation techniques. ARRI Relativity™software is powered by Pixel Strings™, the first engine to harness the potential of GPU-based parallel processing for motion estimation and spatial-temporal image filtering. In its most comprehensive version, the entire Relativity™ software bundle is currently comprised of five different applications: Texture Control, Film Simulation, Clean SP, Retimer and SpaceTime Converter. The software suite is modular and easily configured to meet the needs of each customer. All tools have a simple interface with interactive visualization of the manipulated image.
Features
Texture Control
Control the level of film grain and digital noise, mix and match the textures of 16mm, 35mm and digital images, for a particular effect or visual continuity. Reduce grain or noise prior to compression for Blu-Ray and DVD authoring or any cable/satellite/IPTV distribution while retaining picture detail. Produce impressive theatrical quality images from Super 16mm or 2-perf 35mm. With the optional Film Simulation module, make grain an aesthetic choice by adding a pleasing texture to the finished product. .
Film Simulation
Add natural looking film grain to digitally captured images or CGI. Or add the subtle grain of 35mm film to 16mm origination that has been de-grained via Texture Control.
Space Time Converter
Convert any TV or motion picture format into another, with crop/zoom, spatial resampling, frame rate conversion, de-interlacing and addition or removal of 3:2 pulldown through an easy-to-use interface. Includes audio format conversion and resampling (with or without pitch correction). Resample time for creative tempo changes, slow motion and speed ramp effects.
Retimer
Provides artifact-free, single pass retiming of video and audio (up to plus or minus 10%), allowing broadcasters, content providers and post production facilities to customize program times to fit into new time slots. Harnessing the speed and power of the Pixel Strings™ GPU motion engine, this plugin provides control for extending and condensing video timelines (with or without audio). Compared to more expensive hardware solutions that are limited to drop-frame shorten-only methods, Relativity Retimer allows more choice and flexibility. Ranging from set-and-forget processing to scene-by-scene modifications with slug insertions, this plugin provides an unprecedented level of retiming solutions for file-based content.
Clean SP
An initial treatment for the removal of optical and physical artifacts such as fine dust, fibers and random scratches from scanned film images that typically make up 90% of image defects, Clean SP provides a tremendous advantage when re-mastering interpositives and internegatives, where optical artifacts are invisible to infrared detection. Utilizing the innovative speed of the Pixel Strings™ GPU engine, Clean SP processes with extreme accuracy and speed to provide quality solutions in minutes, not hours or days. By removing the majority of minor defects quickly without eliminating important detail, Clean SP allows more time for clean up artists to handle more complicated repairs.

Demo Clips
The QuickTime movies were generated in a high quality to preserve the texture of the original and of the processed images. The movies are too large for streaming, please download them to your computer.
Texture Control
The JPEG encoded movies highlight the efficacy gained in compression by the noise reduction. With a constant quality level, the file sizes of the degrained clips are around 50% smaller than the original versions. Comparing the two versions of the Car clip show the quality improvement gained by noise reduction when working with a constant bit rate.
