Highlighting a specific part of a Video..? How?

[Moontrash]

i've been sitting on this question for a while until i could show an example video of what i'm talking about...around the 30 to 35 second mark in this vid u'll see a portion of the vid highlighted and the rest greyed out....what software can i use to do this?

Most editing software that allows overlays, opacity masking or canned "spotlight" effects. Most edit programs allow one or more.

You could use e.g. AviSynth Overlay function with (black frame + mask image) as overlay. Mask image is used to control opacity within overlay image of the same size (black portions are for full transparency, white portions are for full opacity), in your case it could be a black spot on grey background. More details in AviSynth docs.

Or VC Mohan's EffectSpotlight filter for AviSynth, part of his EffectsMany package:

the avisynth route was a bust..is there any user friendly consumer video editing software that can do this effect?
