Visual Infinity Ships Grain Surgery for Adobe After Effects and Photoshop

Plug-ins for AE and Photoshop designed to remove, add or match film grain and noise in digital images and film footage (October 26, 2001)
Visual Infinity announced that its flagship Grain Surgery technology is now shipping as a set of specialized plug-in filters for Adobe After Effects. Grain Surgery is designed to remove, add or match film grain and noise in digital images and film footage. It is also effective in removing compression artifacts and video noise, as well as halftone patterns from scans. Applying Grain Surgery's Remove Grain tool also generally results in a significant reduction in file size, an added bonus for Web applications and streaming video.

Grain Surgery is an industrial-strength set of tools which supports the new features of After Effects 5.0 such as 16 bit per channel color, and which gracefully handles images at film resolution and higher. The suite has three components:

* Remove Grain is a clear breakthrough in noise reduction, offering a superior solution to this very difficult problem. Unlike previous techniques, Grain Surgery's patent-pending algorithm does not rely on blurring or averaging. The results are very clean with minimal loss of sharpness and detail.

* Add Grain lets the user precisely define the size, density and color of the required grain as well as several other parameters. Supplied presets which closely match popular film and photographic stocks can also be applied as-is or modified.

* Match Grain lets the user extract the noise model from an image or sequence, and then automatically apply it to a different image or sequence. The user can also modify the characteristics of the extracted grain. A powerful and innovative feature is the ability to automatically compensate for the grain already present in the target image to ensure an exact match in all cases.

"In its default state Grain Surgery is simple to use and almost fully automatic", says Product Manager Louise Shekter, a veteran film and video Producer/Director turned Software Engineer. "But noise manipulation is serious technical business. Each image and each production project has its own challenges. We wanted to give the professional user access to every possible parameter, so that the tools meet the creative and technical demands of any job."

Grain Surgery ships with a comprehensive 125 page manual. Tutorials and free technical support are available online to registered users. It supports both After Effects version 4.1 and 5.0, and is available for either Mac OS or Windows at the retail price of $499 U.S. Demos are available online at

Visual Infinity Inc. (, founded in 1996, is an R&D oriented software shop which specializes in developing advanced solutions to difficult technical problems for the graphics industry. Previous development projects include the popular Evolution series of plug-ins published by Atomic Power, which now ships with Adobe After Effects.
