Hi to everyone firstly. I am totally new to Virtualdub and wishing to use it if possible in a home project. I already have a few videos which I have placed a decent green chroma screen behind the subjects and am wanting to superimpose another video behind so as to create the look of being somewhere else. I have found on the internet a page aboiut using Virtualdub where it says to go to "File" and "Import" both videos and layer the green backed video over the location video and use a filter to remove the green screening and resave as a new video. All sounds good so far but I cannot import both videos at the same time as there seems to be no "Import" option on the "File" menu. Can any one please please help with this as really wanting to complete this home project. Do I need to download and install and other software or filters to achieve my goal? - Many many thanks for any help anyone can give and please excuse me if this sounds a basic task but totally new to Virtualdub - which I think is just great. Kind regards Anthony.

Using my amazing mind reading skills I found this
QUOTE
Instructions
1        Download and install VirtualDub (see Resources).
2        Open the program, then select "File," "Import" and choose both the green screen video and the video you want to replace the green with.
3        Double-click the green screen video, then choose the "Effects" option and select "Green Screen."
4        Click-and-drag the replacement video down to the "Replacement" window. This window is next to the current display window and is blank until you select a desired replacement. The replacement video is located (after import) in the video file bin on the side of the program window.
5        Click on the green in the display window and the green is removed and replaced by the replacement information. Once set, click "File," "Export," then choose a location to save the file, title it and click "OK" to create the exported green screen video file.


If this is the guide your following then your out of luck, as it's complete nonsense
Everything after step 1 is made up or for some completely different program
Good old eHow, still churning out b****x

Hi dloneranger, firstly many thanks for your quick reply. Yes that was what I had found. As I now know that is complete bulls**t I'll ignore it but do you know if there is any other way it can be done through a command line application? Any help would be really helpfull for my college project and willing to pay a little if necessary as really wanting to add this to the project. Kind regards Anthony.

Chromakeying isn't something I do, so my knowledge is limited

Not cmdline, but for free, Wax may be what you're look for - youtube guides for chromakeying with it are available
http://www.debugmode.com/wax/
I've not tried it, so you'll have to test it yourself
