Thanks to whoever takes the time to reply to this!
I was wondering a few things. I was wanting to make a commet, wormhole from scratch with vision lab. I'm wanting to make my own presets, like the Matrix gun fire, where it has that wavy effect with the bullets are shot. I'm not sure where to start when making my own presets, so can anyone help?? Also, I've been playing with a greenscreen and a model Star trek Voyager ship. When I try to take the green out, Parts on the ship turn black. I'm not sure about how to do the lighting when it comes to this. I got the video from fxhome about how to make a sci-fi movie and it shows a man whith a model ship and using a green screen, but when I do it, I cannot get all of the green out and the grey voyager ship starts getting black spots on it and there has been a time it turns pruple. I has a Halogen worklam and 2 par cans with the regular old light bulbs in it, but these bulbs are bigger than a table lamp bulb!! Do I need to use a blue screen? When do you actual need a blue screen?? Thanks for any answers I get!!

Well, there's a bullet trail (matrix thing) already as a present in vision/effecstlab. Oh, and when you say comet wormhole, do you mean like the thing in Star Wa confused rs

A comet and a wormhole seem like very, very different effects to me. It is possible you can give us an example of what you are after? Or a better description?

Making presets is fairly easy; add an effect to the timeline, change the settings around to get it looking how you want, then right-click the name of the effect on the timeline and select Create FXpreset... from the menu. Fill in the blanks in the form that pops up, then click Create to save it to your system, or Create and Export to export a file that can be uploaded to the site.

When greenscreening a model, if bits of the model turn black (I assume there is no background behind the model yet?), they are likely being removed by the key. Most likely, your model was too close to the greenscreen, or the lighting wasn't ideal, and as a result those bits of the model are receiving a green cast from the greenscreen. If bits of your model are green, they will be removed with all the other green by the key. Searching Youtube you can find a number of videos explaining basic greenscreen lighting, else there is a DVD on the subject available here.

The model turning purple would have to do with the spill suppression filter, most likely. Any time you have a question about keying, an image is almost essential to say for sure what the issue is. So the above is my best guess, but if you can give us a link to an image showing the problem, we can be more definite and specific in offering advice.

When to use a blue screen is dependent on the colors of your subject. If your ship has to be partly green, then you would want to shoot in front of a bluescreen. Basically, you want your background to be as far removed in color from anything in the foreground as possible.

Axeman,
The worm hole effect like from Star Trek DS9 after it is open, is a example, the comment thing, I saw on FXHome a video clip for vision lab, there is a fire comment that hits the ground, something like That! I was just taking out the green and it is a model of Star Trek Voyager and it is a light grey. I thought a blue screen was for like if you were using models like in space???????? So, you can use a green screen for that? I had the green screen lit up real good and I was about 7 feet from the green screen holding the model in from of the camera. So, let me know if you can help with any of this! Also, on Visionlab, when you render the video, a lot of times it says something about no audio since I did not make the correct settings on the render?? I have used green screens with Pinnacel studio 10 to studio 12 and never had these problems and now, I can not get it right on visionlab or pinnacle! Thanks!

In regards to your audio problem: Alright two things you need to check. In your render settings make sure they are the same as the video file. If you put in an AVI, render out as an AVI, if you put in an MOV, render out an MOV. If you crop the footage, and any of the clips lengths are altered, it won't render out sound. However there should be a warning before you render saying that it won't render sound. Hope I could help! No doubt Axeman will be around if I can't solve your problem!

Have a wonderful day/night!
