Just playing around with the Vegas Pro chromakeyer, experimenting to see the best way to produce the key. I've done quite a bit of this using the Chromakeyer in the past but want to really get the very very best key I can for a project.

I had a go as per a Sony Creative Software tutorial using the Secondary Colour Corrector but that wasn't fantastic. Reverted to the Chromakeyer and tried the 'Green Screen' and 'Pure Green Screen' presets which worked pretty well - seemed better even than the eye-dropper.

However I thought it would be nice, rather than to use just the slider, or to type in a number in the box, if I could use, say an arrow key or some hot key, to increase or decrease the numeric value .1 at a time - to give more precision.

Is there an option for this?

I've just found the answer to my own question. If you click on a slider on the chromakeyer, and then use the arrow keys - up or down, left or right - or use the wheel on the Shuttle Pro2, you can more precisely control the keyer...

If using the mouse, hold down the CTRL key while using the mouse.

Thanks Edward...another way...appreciated...
