Realtime secondary color correction
The secondary color corrector is an advanced tool used for fine-tuning or
dramatic effects creation. It offers all the controls found in the primary color
correction filter with the added capability of limiting the effect to a specific
range of pixels. Pixel selection can be done using color and/or brightness.
Using the simple garbage matte tool, you can also limit the effect to a specific
region. The pixel selection can also be inverted.
The secondary color corrector lets you achieve effects such as color pass
and color replace. It can be used, for example, to change the color of a
dress, deepen the background sky color, or to achieve an effect similar to the
film Schindler’s List where only one object or person remains in color while
the rest of the image becomes black and white.
Realtime chroma and luma keying
The Matrox MXO2 devices provide one of the finest realtime chroma keyers
in the industry. Clean blue- and green-screen keys are easy to achieve,
even with HDV and AVCHD material shot in less than optimal lighting
conditions. Your video is upsampled to 4:4:4:4 resolution and advanced
noise reduction algorithms are used to ensure superior results. The auto key
button intelligently adjusts the key with soft edges, spill removal, and shadow
preservation. If needed, you can further refine the key with manual controls.
You can key on any color, not just blue and green. You can also invert the
selection and display the matte being generated to fine tune the key.
