Working with MOD file

My camcorder records to flash drive and the file type is MOD working with VS X2 seems fine. I have been trying to work these files on a green screen. I have done all type of lighting arrangments. Even went out and purchase a true green screen (Muslin) thinking that was the answer. I am thinking that it might have something to do with the file type.
Does anyone have any help to provide on this. VS X2 does remove some of the green but I can not get a quality output. I have checked and the light source creates a uniform light on the background.

When you go to Chroma Key have you tried upping the percentage under "Similarity"?

Yes, I had worked with all of the available adjustments within the Chroma key area. I was wondering if the file extension had anything to do with it. I see so many nice green screen videos on small budgets and small rooms.
Just looking at various items to eliminate items one by one to get an answer. Those of you who are more video expert then me I would appreciate your help.

I'm certainly no expert but just to see if it is the file format, do you have a video converter. If not AVS Video Converter supports MOD files and a trial version can be downloaded from here:

The converted file will have a watermark on it but at least you will see if it works.
When you say you can't get a quality output do you mean some of the greenscreen remains visible?

Just had a look at your "system". Your Pent 4 - 2.66 gh processor may not be quite man enough to cope with what you are asking it to do. Perhaps one of our more knowledeable members can look at that for you!

Are you trying your green screen removal with objects in the foreground that you want to stay?
If so, why not start by just filming your uniformly lit green screen, then see if you can remove all of it.
Ligting a green screen is an amazingly difficult art when you have items in the foreground, as the slighest shadow cast will change how the removal works.
You can also try taking a still of a part of the video where the green screen isn't removed totally adn use a photo editing programme to look at the colour spectrum of all of the green screen, I think you'll be amazed as to how different the make up can be even when it looks the same.
I think the pc should be able to cope with the green screen removal, it would baulk at the work given and slow to a crawl, not remove some of the green and leave the rest.
This you may find a good read.

This is a real good suggestion. It looks to the eye that the screen is light evenly. I do not see any shadow of the subject. But I don't have the best of eyes either, LOL.
What I am getting is a jagged edge on the subject. There is green around the subject at various times of the movie.
I will try the trial download of the AVS software and see how this comes out
I am new with all of this and I am sure that it is something simple that I am missing.

Yes, this is the problem. I am thinking that it is the file format but since I am not an expert either I am not sure.
