First off let me say I just purchased your product today and I am very excited! After watching so many awesome movies in the movie vault I couldn't resist. And the price!! Wow, this is something I sure can say you get what you pay for and more! I want to learn this first before moving on too ALAMDV2. Anyhow, now for the question...
I recorded myself on a green screen to practice to do a basic clone of myself like a twin brother. So I didn't do any camera movement I just basically shot than took the green screen out and did the other half. I followed some basic tutorials here online, but for some reason it just looks to fake! I have seen some amazing video's here where the people look like they are really there. What am I doing wrong? It looks to overlapped on the image where even the lighting is all wrong. The green screen part looks more sharper than the background and it looks like those old fashion movies where they tried this effect and you can see its not quite there yet... Am I just using the wrong green screen, ive tried 2 kinds and still the same results?
Thanks In advance!

This is kind of hard to help you without a photo to see your problem...
Well, let's cover the basics, ok? I assume you used the color difference key, right? Well, before I use the keying tools, I always garbage mask the sides that I don't want out, the helps speed-up the render, and makes a more even key on the edges for me. But if the color difference key dosen't work, and you put the spill supression on, Maybe you should change the saturation in the key grade. That helps to make the green more green, and won't negatively affect your final image. Does that help at all?
-Happy to clear anything up,
PS: Always double check that your import settings are exact!

you did render out your effect all the way right? so you aren't watching it in chromy any more? the temp renders in chromy make the image quality 50% until you fully export. If you could post a screen shot or i will host a clip for you, then we can find the problem a lot quicker. Just contact me on AIM, if you have it.
600 force... heh....

To watch everything you have made this far in 100% quality without needing to export it or pre-render the hole thing, click on the small Chromanator logo in the upper right corner of the timeline.

Ok, here is the video... I think it might just be POOR Green screening? I did the whole thing again to make sure I didn't miss a step, one thing that did help out a bit more is keeping the black point to 0 on the Col Diff. But download the video, its like I have little things around me?\

I suspect that your greenscreen isn't very green, have you tried using the Hue Key instead? OR you can go into the Key Grading section and use the Hue Shift tool to make it more green. The Key Grading section (although changes the appearance of your footage) only changes it for the benifit of the keying functions, once you exit out of the keying section the footage will return to normal.
Post up a screen shot of your original footage for us to see, maybe we can suggest something else.

Looks like there are lots of artifacts in the picture, meaning you don't have a good key. Don't worry too much as keying takes a bit of practice to get right, follow the tutorials and play about with your lighting of your screen and actor(s). Don't give up and keep at it.

Thanks guys! My green screen is very poor. I figured it out, its to dark. I noticed better green screens are like a lime color, a very light green. I will buy some soon to see how it works. Thanks again!

Its also possible the realistic things your talking about weren't with a greenscreen but were with the splitscreen cloning which is more real because they are actually in the environment.

Indeed, for splitscreen/cloning effects, it is usually best to film everything on the actual set, then composite the shots together. Using greenscreen will just tend to complicate matters.
The garbage matte system can be used to tidy up troublesome keys.

I was wondering...
There is a forum about how it does take a little while to render, but I was wondering, should it really take an hour for a clip of about ten seconds or so?

that probably depends on your system.

Depends on your system and the complexity of the project (number of tracks, number of filters etc).
