Hello Everyone, how do you blur out the side or backgroud, and still maintain a good view of the key talent in front thats on film already?
Thanks,
Charlie G.
Charlie,
One way is to use an 'alpha effect' mask. You make a stack of three tracks (I'm ignoring any audio here):
The B&W image acts as a mask. Where it is black you see the track above and where it is white you see the track below. 'Above / Below' can be reversed by clicking on the up/down arrow at the start of the track. You would probably create mask in a bitmap / photo editing program. Up to you to choose the shape and locaton of the area of interest. It need not be hard edge B&W, grey edges in the mask area will blend the two versions of your video.
A search for 'mask face' here will get you to several Q&A threads with more detail. Your problem is identical :-), it just that you want to keep the face clear rather than obscuring it!
Regards,
Carl
Hi Charlie,
Carl's method is more intuitive but there is another way that's sort of built-in to MEP which uses two tracks instead of three.
This image below shows a couple of examples of the results. They're identical to what you'd get following Carl's instructions, but using this alternative method (which Magix actually calls Effect Masks).
Or for better quality: https://dl.dropbox.com/u/4019461/MEP2013-EffectMaskExamples.jpg
For details, see this tutorial I posted a few months ago:
