hi I am a 3rd year computer...

hi
I am a 3rd year computer science undergraduate student,wanting to do a project in multimedia, so i am in need of U'r help,hope u would do the needful.
actually I'm thinking to develope a software package,which can operate on video and audio.
By operate ,i mean,
take for instance i have a video file of say 5 minutes,this software should be in a position to cut the file from a specified start location to a specified end position,and save it to the hard disk,without effecting the original file.
The same thing is true with the audio file as well.The user must be in a position to specify the start and the end positions.
Can U please help me and tell me if it is possible to develope this in 4 months by 2 people working togeather.
If yes, can u tell me what all techinical stuff i'll have to learn ?
thanking U
