remove a moving spot of light
Posted by Bob Pit on August 10, 2009 at 9:21 pmThere is a small beam of light coming from a window and falls on the face of a person. As the person moves his head, a small spot of light moves around his forehead and chicks. Is there an easy way to remove this? Otherwise it was a good take of the video.

Basically, you should be able to use the methods given but apply the cookie cutter fx to allow the correction to show through on the rest of the track. I would think you would want to feather it and track it with keyframes.
Here is the thread I am referencing.

August 11, 2009 at 7:34 amI just read the thread. It talks about changing the color in the entire frame. Like I do during color correction.
But I only want to do color correction to a moving spot (the size of a human eye) on the face of the actor. This is different.

Not really.
Jeremy suggested following the concept mentioned in the thread (I’ve used it and it works!!) but using a cookie cutter to isolate it to a specific area.
Because your person moves around, this will involve keyframing, potentially a lot of it, as the spot of light moves around.
BTW, a bezier mask will work too. -

I am sorry, I do not know what all these are (like keyframing).

So you’re a rookie then. No problem as that’s what we’re here for.
The online help menu is always a very good place to start.
Bezier masking is explained in this tutorial from Sony.
In a nutshell, it allows you to create a custom shape to mask (block) things out and replace it with anything else such as another image of an effect.
In your case, it will allow you to greatly reduce the light gleam.
Keyframes are a way of telling an effect (what a bezier mask is) to move to a certain position at a certain time.
In your case, you would get the effect set up at the beginning of the interview.
Then, as the person’s head moves around, you create new keyframes that tell the effect to move to the new position.
The number of keyframes required will depend on how much and how often his head moves around.
Are You Exposed? by Douglas Spotted Eagle is another good tutorial that uses a cookie cutter to get similar results.
Work your way through these, let us know if you have any questions and we’ll do our best to help. -

Some of this may be a bit daunting for a Vegas newbie so don’t be afraid to put up your hand and say “help!!”. -

August 11, 2009 at 5:24 pmThank you. I can do trimming, white balance color correction, audio noise reduction. That’s it more or less.
