How to create masks for the effect in Boris Continuum (for Sony Vegas)... I see that every effect has something called "PC region" and "PC matte". Is that it? But I cant figure out how to create masks with it...

Hi,

Here are the steps:

• Apply a filter to a clip in the timeline
• Go to the Video Event FX window
• Scroll down to the PixelChooser pop-up in the filter controls, click on it and select "On" from the list
• Twirl down the PC Region and click on the Shape pop-up - select a shape from the list - you might want to start with Inside Rectangle
• Twirl down the Point 1 control and drag the position marker to set the top left mask region and observe how it affects the mask
• Repeat with Point 2 control

You can also use the pixels in the image clip to make a matte via the PC Matte group

I hope this helps.

Peter.

Thanks! Anyway, I cant figure out how to move the mask or tilt the mask... I know only how to change size of the mask. BTW, its possible to make my own shape of the mask?

Hi Petr,

That effect shouldn't be that difficult to emulate in BCC.

• Apply the BCC Pyramid Blur to the clip
• Go to the PixelChooser
• Set it to On
• Go to the PC Region control group
• Select Outside Rectangle from the Shape pop-up
• Twirl down the Region controls and drag them until you see that the blur is on the top and bottom only
• Increase the Region Blend value so that the edges of the focus field are soft

Done!

Cheers,

Peter.

The Pyramid Blur filter generates a fast, basic, out of focus / blur effect.

The Lens Blur is a blur filter with shaped highlights (bokeh) in the defocused (blurred) portion of the image. The highlight shape is derived (conventionally) from the aperture of the focusing lens and is either circular (mimicking a reflex / mirror lens) or multi-sided (mimicking conventional glass lenses.)

I hope this helps.

Cheers,

Peter.
