Convert other file types to .mp4 on upload (ASP.Net)

I want to make it very clear that what I am asking help with is definitely beyond my coding expertise. I will need lots of help to do this. I am building a website that allows members to upload short videos. I store the video in a directory and I store the reference to the video in SQL Server 2008R2. I use Flowplayer to stream the video and play when the user selects one of them. My major issue is I won't be able to determine what video format a user is uploading. And if I did I would not prevent them. What I desperately need to be able to do us convert any video the user uploads to MP4 or .mp4. I am using an ASP.Net FileUpload control to upload the video. The upload and playback works perfectly but again I want to convert the files on the upload. Example...User uploads a .3gp file. I want to convert the file to .mp4 and store it as mp4. My hope is that someone can provide code that can be added to what I am pasting here to make this work. Thank you all in advance for your help.

I would suggest you find a video conversion tool which supports command line parameters. You can then call this converter from your VB.NET using Process.Start (http://www.dotnetperls.com/process-vbnet). This might be the easiest route. I am not aware of a .NET library that converts between numerous video formats.

MoveAvi
http://www.movavi.com/video-converter-command-line/how-it-works.html

Format Factory
A command line along these lines (I got this from http://www.wxforum.net/index.php?topic=18011.0)

"C:\Program Files (x86)\FreeTime\FormatFactory\formatfactory" "All to WMV" "High quality and size" "k:\mymovie.avi" %1

"All to WMV" and "High quality and size" are actually parameters passed to formatfactory. "k:\mymovie.avi" is the avi created by MovieSalsa. "%1" points to the output wmv file.

Commandline utility which converts virtually any format into any other format.

Both of these look like they will get the job done. I have read good reviews on the products so I will give them a try.
