I've shot some video and I beleive something is messed up with one of the CCD's in my camcorder. In nearly every shot has a green do in itt. It is in the same position in every shot. My question is, will it be possible for me to clean this up in vegas, and get rid of that green dot that apperars in all the shots. I havent began transferring the video to my PC yet, but I just wanna know if it will be easy to get rid of it.

It's not going to be "easy" to get rid of. If it's a single pixel or a few pixels in a select, static area, then you can create various masks, but if it's a moving target, it's going to take some track motion and a mask. It's all dependent on what's in your shots.
I've read off and on about a Virtual Dub filter that can be employed to remove a small area of troublesome pixels and create a 'rubber stamp' cover, but I've never used it, so can't comment on it's quality or lack of quality.

Are you sure the green dot isn't on the camcorder's monitor only (i.e. seen it on an external monitor)?

Hmm... sounds like im screwed, this project is due the 25th and Im not even in the editing stages yet. I wish I had some footage I could upload to show what was going on. The pixel is in the same spot, never moves. Its kinda hard to explain. Maybe I'll have to give the dot a menaing in the explanation of my movie.

I have seen it when using the S-video to connect to may TV aswell, so Im pretty sure its one of the CCD's or something.

II just imported one clip, is there anyway I can tell vegas to replace one pixel with the color of another? Meaning can I tell Vegas to replce the busted pixel with the same color as the pixel right next to it? Or am I asking more than whats possible? Thanks for the quick reponses, all help is appriciated.

You'll have to keyframe that in. Fortunately, with the eyedrop tool this is very easy. Just time consuming.

I get a green dot every now and then as well. Sounds the same as you. What I have noticed is that if a bright light hits the lens the green dot appears. I also notice that if you are on a dark area, or the spot where the dot is rather, it won't read all the time even though it is still there (ie - pan from a dark area to a light area and the dot appears). In my case the dot has never been a massive problem because my dot shows up down in the lower part of the image.

Mine seems to be very similar to yours, if the area where that pixel is is dark, then theres no dot, if its completly white, no dot, but any other time thers a dot. Mine is like just right of center screen, so I gotta get rid of it somehow.

Do you guys know of any other editing program that can do it for me?
I have access to:
Premiere, Final Cut Pro, Avid Express, A stand alone box (its called a casablanca), and of course vegas. If any of those can get rid of it for me let me know.

I would think it would be easy to overlay the video with a mask comprised of a copy of the video that has been run through a cookie cutter and blur operation. In other words, I'll bet a tiny amount of blur over just that part of the picture would be almost unnoticeable. Then again, maybe not.

Okay, then how about a cookie cutter on top of generated media of a neutral grey color. In other words, replacing a green dot with a grey dot? Or a black dot?

Wait! Wait! (facetious idea ahead) I've got it! Just shoot green things. Nobody will ever notice the green pixel.

Here's an idea:

1) Use photoshop/PSP to make a 1 pixel mask over that area.
2) Setup the mask so that that the 1 pixel is transparent (shows layer underneeth)
3) copy the video to the layer under the one with the "bad" video. pan/crop or trackmotion it over 1 pixel.
4) Enjoy the fact that it's easier then using fancy cut/paste techniques. :)

And with this method the green dot should be gone form all of my scenes since its in the same spot correct? If so I cant thank you enough!

hmmmm.... except that your mask won't change color when the background video changes, so I think you'll just get a different color spot. Or am I missing something?

You may want to try the free "Delogo" Virtual Dub filter available at http://neuron2.net/logo.html. This filter automatically averages surrounding pixels, based on a static still bitmap you create. A little tricky to set up properly, but I've found it works well once set up. Should be perfect for your application.

You can use Virtual Dub filters in Vegas either with Satish's old PlugInPac, or the new Wax 2.0, both available for free at www.debugmode.com. Or, run your video through Virtual Dub before importing into Vegas.

Good luck!

Thanks for all the help guys, I got all my footage in and overlaid a picture (trasparents w/ 1 black dot) and everything came out looking greate, now theres just one black dot, but on the projectors we use to show the films it will show up alot less obviously than a green one.

Thanks for the help. Now I gotta work on getting 2 hours of footage down to 10 minutes.
