I am exploring the visionlab studio

When i tried the bluescreen keying, the actor is having some waves around him (in the edge) sort of watery motions. How can I make this good?
And the actor becomes transperent in which the background is seen through him.... can some one help pls?

How can I make it seem that it is night, when I film in the moring pls?

This video tutorial Explains a lot about green and blue screen keying and should help a lot.

As for making a day shot look like a night shot, Vision:ab has a day-for-night grade filter that you could use. There are also presets that you could use to do this with, like this one. Try searching the preset library for more.

A very important and not to be overlooked aspect of shooting day-for-night is the lighting. The way moonlight or artificial light plays off of objects at night is much different than the way sunlight interacts with the same objects. Just using a day-for-night filter generally looks ok, but to really sell the effect, so it genuinely looks like night-time, proper lighting and exposure can make a big difference.

Make sure that you have set-up your project correctly, the different UV blur filtering can improve the keying, also try using the spill suppression filter to eliminate the blur edging. Also look at some of the alpha filter, perhaps sharpen.
