ASSIMILATE SCRATCH v6.1.723 x64 for Windows/MACOSX | 75 MB & 113 MB
The system of color correction and finishing grade video-tv-movie projects. Working with the material up with a resolution up to 4K. Unique algorithms allow the image to achieve unprecedented speed. The set of handy tools and original techniques for achieving optimal results. Uses the language from Nvidia Cuda on modern display adapters.
SCRATCH is the most comprehensive digital cinema imaging and workflow tool for digital post-production workflows. Designed to meet the unique DI workflow challenges of independent and documentary filmmakers, as well as boutique post-production houses, SCRATCH brings together playback, conform, editing, color grading, titling, compositing and finishing into a single, consistent interface that maximizes both creativity and productivity.
SCRATCH is CUDA accelerated and you should use NVIDIA Quadro 4000-6000 series graphics cards. Always check on the Assimilate support website for which driver to install for your card as not all drivers are tested.
You need a minimum of 12 GB of RAM.
Whether Direct Attached or SAN storage, bandwidth is a key factor in getting real-time playback performance. For example, if you wish to maintain 2K stereo real-time playback you will need to sustain 1000MB/sec. We recommend a 10 bay internal or external RAID storage for media files.
RED r3d Decoding
SCRATCH can perform RED r3d decoding at various resolutions and de-bayer qualities to match the real-time performance of your computer hardware. If one, or two, RED Rocket cards are installed, full resolution and premium de-bayer quality of can be achieved (in stereo with two cards).
SCRATCH can be driven from Tangent Devices CP200 or Wave and the Avid Artist Color Panel.
SCRATCH is optimized for Windows 7 64-bit operating system.
Single Xeon i5 or i7 is minimum spec. Recommend dual.
To add additional cards for SDI, Audio and Red Rocket Cards aim for as many x16 sized PCI-E slots as you can.
The NVIDIA cards offer dual DVI outputs, and Scratch allows you to configure the second as a full-screen output that will not have the user interface overlaid on it and can be used as a clean feed for projection, client monitoring or output to a tape deck.
For SDI monitoring and SDI playout you should purchase the SDI daughter card for the NVIDIA. This card has two BNC connections that can be configured as a single or dual link SDI output, and one video monitoring output as well as a BNC connection for external sync signals.
Stereo monitoring is available via the on-board audio (speaker) output. For "advanced" monitoring, including multi-channel audio, and playout to tape a professional audio card like the Lynx AES16e or a combination SDI / Audio card such as the BlueFish can be used. If you have purchased the NVIDIA SDI daughter card, there is no need for an additional audio card, as the SDI option also gives you embedded audio.
A powerful Mac Pro will be required if you have video clips in a raw digital camera format, or for working with projects in HD, 2K and 4K. On the Mac you have fewer configuration options.
Max OSX 10.6.6 or higher.
Minimum Processor requirements: Two 2.4GHz Quad-Core Intel Xeon "Westmere" processors.
The NVIDIA cards offer dual DVI outputs, and SCRATCH allows you to configure the second as a full-screen output that will not have the user interface overlaid on it and can be used as a clean feed for projection, client monitoring or output to a tape deck.
Dual Monitor: Resolutions of up to HD resolution
The Mac requirements for a dual monitor are a passive converter Display Port to DVI converter then DVI to DVI which only supports HD resolution.
Dual Monitor: Resolutions of up to 2560x1600
An active Dual Link DisplayPort to DVI adapter is needed to get full 2560px. Since the Nvidia fermi series only has one DVI port and two display ports.
The current graphics drivers you need are the Cuda driver 3.2.17 for Mac OSx and the NVIDIA retail 256.01 driver (you need them both).
If you plan on using a RED Rocket card you will need a PCIe x16 slot.
