SCRATCH benefits




One tool to buy and learn for the entire post-production workflow

SCRATCH delivers real-time data management, dailies, conform, advanced color grading, 3D compositing, finishing and mastering- all in one place.

So, you don’t have to buy, learn and then integrate multiple disparate applications.

SCRATCH is insanely fast - delivering better client-attend sessions.

SCRATCH squeezes every ounce out of your GPU(s), so you can fly through creative DI sessions with your client. Even in 4k with tons of layers, the SCRATCH UI is real-time and responsive.
And the unique SCRATCH CONstruct™ timeline organizes shots for incredibly fast non-destructive versioning.
SCRATCH delivers DI and finishing at the speed of your imagination.





SCRATCH will save you tons of money on VFX.


Only SCRATCH seamlessly blends world-class color correction with deep 3D compositing and OFX plug-ins in one unified, real-time system - at a price you can actually afford.

This way of working is not only faster and cheaper, but the ultimate in creativity.     



With SCRATCH, you can work with anything.

SCRATCH starts by opening any format you can throw at it, so it’s a must-have for playback and VFX dailies review.

It supports seamless Avid and FCP integration and round-tripping and it’s a killer conform engine.
