Professional Colorgrading

Imagine a grading system that operates as fast as you think. That is SCRATCH.
GPU-based since 2003, SCRATCH has become the go-to software for professional colorgrading and finishing. Literally anything is just a click away - or, thanks to user-defined panel mapping, a button push. Through its advanced grading tools and easy-to-use color management, SCRATCH allows artists to never say no to a client. You can work layer-based or node-based with top-of-the-art color tools such as Vectors, Curves, 6 different Qualifiers, beautiful scopes and much more in the most streamlined UI the industry has ever seen.


High-End Finishing

SCRATCH does not stop at colorgrading. It is a complete finishing tool, that allows for realtime client-attended compositing, using OFX plugins and free matchbox shaders. Need to place a police car here? Add sky replacement there? Remove that crew member in the background?
With SCRATCH, it's done within seconds, while the client next to you drops his jaw to the floor.

VFX-Review and Asset Management

SCRATCH is being used by major VFX houses around the globe as the central hub for VFX shot management and review, since it allows to easily manage a zillion versions of shots and timelines in the most visual way possible. It conforms EDLs, XMLs, AAFs and more - including support for Avid Markers to update clips with VFX shotnames. Through its excellent metadata support, SCRATCH can transcode camera RAW footage of any kind into metadata-rich OpenEXR sequences, even with frame-based metadata. SCRATCH's review tools allow for simple note comments in various colors, as well as on-screen annotations - all of which can be exported as PDF reports.


High-Speed Dailies Transcoding

Being an essential part of DIT Pack+ SCRATCH sets the industry standard for dailies transcoding. It has automated features for LUT application, look management and audio-sync. SCRATCH pulls as much metadata as possible from both, audio files and camera RAW - including frame-based metadata - and automatically forwards everything to the target format. No matter whether it's DNx MXF for Avid workflows, high quality H264 for online review, OpenEXR for VFX or ProRes Quicktime for Premiere and Final Cut workflows - SCRATCH encodes it at an incredible speed, equally on macOS and Windows. Being able to export extensive Clip reports for any use case goes without saying.

We do a lot - but we don't want to be everything

Every software has its limits. When reaching those limits, it's paramount to have a fast-track connection to other software. This is why SCRATCH features integrated bridges to Nuke and After Effects, native support for ScopeBox and Nobe OmniScope, as well as a direct integration with Light Illusion's ColourSpace calibration software and Hedge Offloading and Backup. And if that is not enough, you are free to integrate it to any level into your custom in-house pipeline via XML scripting hooks.


NotchLC - a powerful codec for volume projection and more

SCRATCH allows to encode and decode NotchLC Quicktime clips of any resolution on Windows and macOS (incl. Apple M1 support). With its powerful decoding engine, SCRATCH can playback 8K and beyond even on modest hardware. This makes it highly suitable as a player for large volumes or other LED wall installations.

Until the end of 2022 we offer a free add-on trial license for the NotchLC encoder. With this it's posstible to encode any content, whether it's ProRes, Notch Blocks, or camera RAW footage to NotchLC in resolutions up to 16k x 16k. Included in the resulting NotchLC files is all source metadata, and most importantly playback relevant metadata like color space and gamma information, so the content shows up on the LED wall as intended. Try out SCRATCH with the NotchLC encoder by clicking the TRY button on the right!


Notch Blocks - next gen 3D environments

With Notch Builder, you can create amazing motion graphics and interactive VFX in real-time, then generating Notch Blocks as output. SCRATCH can import and manipulate Notch Blocks* - complete 3D environments, built in Notch Builder. Depending on which parameters are exposed in the block itself, SCRATCH can animate more than just the camera position and FOV: Any object or property of the scene is adjustable. Using SCRATCH's powerful animation editor, users can now create complex camera moves, or import camera tracking data from on-set to recreate the movement of the physical camera. That's not all - Notch Blocks can also have any number of inputs, that SCRATCH can feed textures or plugins into, in order to create the perfect illusion.

*requires a Notch Playback license, which can be obtained from the Notch website.
