Grade tools

Prelight supports authoring with the full set of Baselight primary and secondary grading tools and these tools behave identically to a full Baselight system, including spatial operations and all applicable inside/outside mattes produced by sophisticated keyers. Specifically this includes unlimited layers of:

Grades

• Blur/Sharpen
• CDL Grade
• Curve Grade
• DeFuse
• Film Grade
• Glow
• Grain
• Hue Shift
• Look
• Six Vector
• Soften
• Truelight
• Video Grade

Mattes

• Shapes (freehand as well as presets for adjustable edges, corners, spots, vignettes)
• Matte RGB
• Hue Angle
• DKey (view-only)

All grades are processed inside a framework that manages the necessary colour space transforms to ensure repeatability and consistency when the grades are applied anywhere else in the chain.

And, of course, additional grading functions will be added to remain consistent with the current Baselight release - such as the Base Grade in Baselight 5.0, which brings a completely fresh approach to colour grading with a more natural, photographic way of working.

Image analysis

The application has numerous tools to enable the quality of an image to be assessed at-a-glance:

• Histogram
• Vectorscope/Chromaticity
• Y’CbCr Parade
• RGB Parade
• Luma Waveform
• Colour picker
• Wipe comparison
