I am new to this forum and would like to ask a question that has not been answered yet on any other forum. I am a special educator in california who love to integrate video with my studnets lesson. I am now working on a project with them and I need some direction on where to find specific clips, effects or transitions to finsih my project.

The specific effect I am looking for is where my video clip can become out of focus, grainy, scratchy or with any other efffect as if it was being unplugged, hit, disconnected, etc.... you know when you would slam your hand down on the old tv set to make the picture come back in. I love the white noise effect and snow look as if my picture just went in and out. I want to use them all in my transisitons between clips to give it a funny feel as if something was going on withthe connection.

I don't know where to begin to look for something like that, and don't know what keywords to use to look it up.

Can somebody please direct me in the right area?

I don't know of a transition that will do what you want, but you could try splitting the end of your clips into a number of sections and adding successively larger ammounts of noise to them. That's probably too time consuming, so perhaps you could produce a short clip which has the noise on a transparent background (perhaps using chromakey) and then use that as an overlay. You could also experiment with adjusting the transparency at the end of your main clip.

Here's what you could do...

Take a video clip, and split it into clip A, B and C where clip A is where you'll "fade in" with the effect, clip B is the body of the clip, and clip C is where you'll "fade out" with the effect.

On clip A, apply an effect such as "add noise", "pixelate" or "blur". Check the box between "Begin" and "End". For the Begin value, specify "1" meaning full pixelation. For the end value, specify "0" for no pixelation.

On clip C, apply the same effect, e.g. pixelate. For the Begin value specify 0, and for the end value specify 1.

Now play the segment A through C. Your clip will do what I think you're describing. If you want it to sort of fade in and out then you'd have to split multiple times and repeat the process above for each segment, which can be laborious. With "full" Vegas, you could use keyframes to do this. (Every time I think about things like this I wan to buy Vegas!)

I uploaded a short file to http://www.vegasusers.com/vidshare that shows this. (Not sure how long it will take to show up there.) You should be able to search on "gogiants" or "needed effect" to find the clip.
