Suggestions Requested please

I need to write a program to allow my boss to be able to edit/manipulate video files (mp4, avi, wmv, etc). I need to be able to do the following:
View a video file,
while viewing the video file, be able to set a start and end point inside that video file to be able to create a new, very small video file of just that segment
be able to take multiple video segments and concatenate them into a new video file.

Does anyone know of an API out there that has this capability? I've heard Silverlight can do it but this is NOT web-based (Silverlight is web-based, right?).

These API's/software can be free or for purchase software, but I must be able to create my own interface to utilize the software.

Any help/suggestions are appreciated!
Thanks

I recommend using a ready-made solution rather than writing your own. One free, opensource option is virtualdub http://www.virtualdub.org/

If that doesn't quit suit your needs wikipedia has a list that may interest you: http://en.wikipedia.org/wiki/Compari...iting_software

For a project of this complexity for internal use it is a much better use of your time resources to just use a solution that already works.

Hope that helps.
