Report Generator


Media and data management is just as much at the core of SCRATCH as its creative tools.

The latest version has additional media validation functionality to check the availability of the underlying media of multiple timelines and thousands of shots and versions. This ensures correct and uninterrupted renders. Calculate MD5 hash and add it to the meta data of the media to be used in reporting.
SCRATCH 8.6 comes with a new set of pre-defined clip reports that you can generate from a single timeline, a set of dailies or your full project. The reports are fully customizable, including adding your logo, selecting which metadata to include and adding custom ad-hoc information into the generated report.

SCRATCH has always been at the forefront of new camera support. More cameras, more formats, more resolution.
• Create H264 in 10 bit, up to 8k (8192x6144). Include HDR metadata directly in your mp4 output or generate a separate report with HDR statistics and transfer function specifics.
• Enhanced support for DNxHD and DNxHR: rendering faster than ever, including all metadata for a seamless AVID roundtrip.
