Green Screen question - using the pen and what does it do?

[lbreslow]

I am doing a project that is 75% Green Screen. Some of the images blend into the background fine. However, I am getting a lot of haloing around many of my figures. It is also transparent through the foreground. Anyone with some suggestions?

I am also not familiar in using the eye dropper. Can someone help me to understand it.

Thank you for helping me. If I can return the favor let me know. I am a retired film and video editor but am not familiar with using some of this tool.

The eyedropper is used to select the color you want to make transparent. Click on the eyedropper icon and then the color of the clip you want to make transparent. You can then adjust the similarity slider to specify the color that will be rendered as transparent.
Refer to page 88/89 of the user manual which is downloadable from the Ulead web site.

Perhaps I didn't explain myself correctly. What I am trying to do is eliminate a transparent affect. I have imported images that I am using as background, my green screen is children who have become transparent; the background is bleeding through. How do I correct this? Also, there is a halo affect around the children. I was trying to fix both of these problems by using the eye dropper, but I don't think I was using it correctly. I would like to know how to use the eye dropper, but more importantly is this transparancy issue. Hope this helps to clarify my dilemna. Thanks for your prompt reply. Look forward to hearing from you again. Larry

After viewing the background and overlay it seems that most if not all of your problem is due to the fact that their are two many hues of green in your 'green screen' background and also there are deep shadows cast by the boys. Some of the colors worn by the boys are probably too close to some of the green background colors also. The similarity slider is to adjust to allow/disallow similar colors to those chosen by the eyedropper but it won't allow for everything.

John,
After you helped me to resolve my GS issues I started to "play" around with my material. I managed to fix most of the GS problems by working with the Color (contrast, brightness, etc.) to adjust both my background and GS. I guess that that is the best way to make it look reasonably good.

I just finished my project, and for the most part, was very happy with it. I will have a showing for my school kids on Friday. Once the project was rendered it dramatically fixed the GS problem.

It would be very helpful if Ulead could give us more "detailed" instruction on how to use the I dropper. I also wish the could also make it possible to do some basic effects on the first layer and possibly the second layer as well. Perhaps fades and dissolves.

I hope this helps others to identify their green screens and take notice of how they are going look on the individual projects. My suggestion would be to make sure that the screen you are shooting against is lighted, not creased and make sure that the "people you are using" are not right up against the backdrop.

Thanks for the help!!!!

I also wish the could also make it possible to do some basic effects on the first layer and possibly the second layer as well. Perhaps fades and dissolves.

You can do basic effects like fades and dissolves on the first layer (the main video track), but not the overlay tracks. They're referred to as 'Transitions', which may give a false impression of how they can be used. While they can of course be used as a transition from one clip to the next in the traditional sense of the word. Another common application is to use a combination of cross fade transitions and colour clips to achieve the fades you describe.

peace.

I do know the difference in what transitions are and how to use them in the Video channel. My question is do any of the other subsequent layers, 2,3, 4, etc. give me the opportunity to make any transitions ie. Fades or dissolves.

Example: In my Green Screen I would like to fade in my images, once they are on the background, or to fade out or dissolve into the "B" or A" side of my next cut.

If you can do that with your text, why can't you do it on the other Channels?

That's my question. All I wanted to know is it possible to do that or not.

Thanks for your help. Larry

My apologies, I mistook your reference to the 'first layer' as meaning the main video track rather than the first overlay track. It is possible to fade in and fade out the items on your overlay track(s), but that's about it. I'm not currently on my video machine so I can't check the exact location of buttons etc, but I'm sure there is an option on the attribute tab (or somewhere) for fade in and fade out.

peace.

There is a post which includes something about transitions in overlay tracks.
