Unique timecode options can sync timecode from multiple cameras and even create timecode for cameras that don’t have it.

SCRATCH Lab can even capture metadata automatically from broadcast wave audio files.     




QC and set looks faster than
anyone else.

SCRATCH Lab is built on world-class color grading
tools that allow artists, DPs and Directors to collaborate
in real-time to set looks and create LUTs.

Render in the background while you work on your next shot.

SCRATCH Lab is fully GPU-accelerated, so you no longer have to wait for a render to finish before you continue working.
