PrimatteTM V4 is the latest version of the popular Primatte Keyer.  It is faster and easier to use and includes many new features compared to the previous Primatte implementation.

Primatte V4 includes a Quantel hardware-assisted Keyer in the “Key” menu in Effects and a software keyer in the “QPlugin” menu. The hardware-assisted keyer has faster performance but fewer features than the software keyer. The software keyer offers Primatte’s full feature set and precision. On machines without Quantel hardware the hardware assisted keyer is still present but it runs using software emulation of the Quantel hardware.

New Features

Faster Processing
Speed optimizations in the code makes this the fastest Primatte ever.

Improved Spill, Matte and Detail Sampling tools
These give a much finer and incremental control over each of the functions resulting in far greater control over the resultant key.

Floating Point/Integer Calculations
All internal calculations done in either Floating point or 16-bit Integer. Floating point improves both accuracy and speed.

Auto-compute (s/w only)
One click of the Auto-Compute button detects the backing screen colour, eliminates it and cleans up the foreground and background noise. Follow up with some spill removal to complete most well shot clips.

New Keyer Viewing Tools (s/w only)
In addition to the keyed foreground and normal view key modes, now see processed foreground with spill suppression applied, Defocus source – this displays the foreground with Grain Removal applied.

Defocus Replacement Spill Suppression Mode (s/w only)
This uses a defocused copy of the background image to determine the spill replacement colours instead of a sold palette colour.

Inward Defocus Tool
A method of defocusing the matte where the softening is only applied inwardly. Toward the centre of the foreground subject.

Median Picking
Filter out noisy pixels when doing sampling and picking operations by applying a 3x3 median filter on the sampled input pixels prior to performing the sampling operation.

Degrain Tools (s/w only)
Clean the background but still preserve the fine edges on the foreground object by using the Degrain feature to support cases when there is a lot of noise (usually caused by film grain) in the foreground image that makes producing a good extraction difficult.

New matte extractions (Primatte RT and Primatte RT+) (s/w only)
These algorithms are modified versions of the original Primatte algorithm and use the Primatte Polyhedral Slicing Algorithms. They allow for accelerated processing if your clips are well lit and photographed.

Great deals on upgrades are available for customers with the previous Primatte version.   Primatte V4 is available for V4.0rev5 or later software.
