How to do a "tracking mask' to cover blemish ?

Not sure if this can be done...

We have a clip and one of the subjects had a blemish on them.

Is there a way to mask it... say with a 'smear tool' or whatever... and then tell Vegas to track the subject keeping the mask over the right spot?

Thanks for any help.

There is a way to do a smear or blur, but Vegas does not have the tracking feature. You would have to program that yourself using motion and position keyframes.

I think it really depends on what you want to blur and how big the blemish is on screen. Photoshop CS3 will let you import video and rotoscope on it, using their blur tool - really cool for this kind of thing but you're stuck either way doing something frame by frame to conceal the blemish.

Hopefully it's not a moley mole like the principal had in Uncle Buck ;)

There are programs that can do automatic feature recognition and tracking, enabling all kinds of fancy effects. One of the least expensive, but still very powerful is "SynthEyes" starting at US$400. http://www.ssontech.com/synovu.htm

you can try the cookie cutter tool to isolate the blemish, then add a very soft blur effect or color correction to deal with the blemish.

Have that on track one and the full clip with no cookie cutter on track two.

you would still need to keyframe the cookie cutter for movement.

Boris FX 9 has a nice motion tracker along with a lot of other great tools and FX. Vegas users get a discount if you have the LTD version which was offered with Vegas 6 or 7 (I forget which). Boris FX is also on sale for 50% off at DigitalJuice ($149 USD). Otherwise you need to manually keyframe to track the motion yourself. Personally I'd pick up a copy of Boris FX since it does image stabilization, motion tracking, corner pinning, particles, keys and mattes, and tons of other FX. Well worth having in your kit for the 50% price.

Hi JohnnyRoy. I looked at the DigitalJuice website but could not see any mention of BorisFx for $149. Do you have a link for this please?

Thanks,

Richard

Is the image stabiliser feature in Boris FX as good as the one in Boris Red or is the difference between these two more in the quantity of features rather than the quality of the individual features?
