State of the art metadata and timecode support

Sync timecode from multiple cameras (including stereo) with a unique “Match Timecode” function. Stack cameras into a single slot, then automatically sync the timecode all of cameras to one of them.

  • Generate dailies by automatically naming clips based on any metadata field, including camroll, scene and take.
  • Create flash burns either at the top and tail of a clip, or throughout its duration.
  • Capture scene and take metadata automatically from broadcast wave audio files.
  • Automatically generate new timecode for DSLR cameras such as the Phantom, Canon 5D/7D and GoPro that don’t support it. Easily increment the timecode with each slot and even skip by user-defined intervals.
  • Populate Avid AAF files with extended metadata, avoiding the double pass to access that ALE files required. This effectively removes the need for separate ALEs.
  • Select, update, add or remove metadata in a spreadsheet editor-style. Update metadata for a single shot or multiple shots at once, as well as update data by entering plain text or using formulas that contain other metadata items. New metadata can then be exported via ALE or XML to be imported into other systems or integrated with other proprietary tools.
  • Match/find, load and apply looks to multiple shots in the form of 3dl, CDL, LUT or XML, and audio. This new feature will search and match by name, time-code, or any common metadata items. In addition, artists can now auto-link audio files to shots purely based on metadata and file name.

An entirely new, flexible viewing model

Create dual views of any image in a project by quickly and easily selecting a version, a reference, a clip from any video track, or a color buffer.

  • Compare them using one of two methods: a difference method, or an overlay method with opacity controls and a 360 degree wipe
  • One of the dual views can be designated as an output view (showing the final result of a shot), while the other is a fully functional working canvas with access to even the deepest elements of a shot, including a complex composite or color grade
  • Intuitively manipulate any element of the working view and instantly see its resulting affect updated to the output view at full resolution and in real time

Stereo 3D workflow support

Imagine the creativity of a full stereo workflow that provides consistent, intuitive feedback during the conform, color grading and finishing process. Stereo image pairs are automatically linked for versioning and real-time playback to a wide variety of stereoscopic delivery systems.

  • Check and adjust stereo with dedicated link and convergence controls
  • Bicubic controls for fixing 3D stereo images
  • Position elements relative to the screen plane
  • Immediately review decisions in stereo
  • Panasonic 3D stereo camera support with automatic stream de-muxing

Flexibility and extensibility

Future-proof your workflow with an advanced and scriptable XML back-end that allows you to:

  • Automate SCRATCH to maximize productivity
  • Access your job anywhere via HTMLIntegrate SCRATCH via XML with other tools in your workflow such as Nuke, Shotgun, Avid or Final Cut Pro
  • Enhance SCRATCH with OFX plug-ins such as Sapphire, Beauty Box, Twixtor, and Neat Video
  • Built-in SQL database supports a full range of metadata

Advanced audio sync

  • Broadcast wave support
  • Automatically sync to timecode or slate
  • Interactive waveform for sync
  • Interactive audio scrub

Live View

The new Live View function takes in the SDI signal from a camera and allows artists to work and grade directly on the camera feed. It also reads the camera metadata if available, which is then displayed in the metadata stack in the Player module. In addition, the name of a SCRATCH Gallery item can be based on the metadata of the current shot (e.g. Live View). The determined grade can then be easily linked to the recorded shot further downstream in the pipeline.
