Downloading video of high speed crash?

[JOHNNYMAXXIMA]

I tryed to download the video I took of my truck crashing at about 45mph. I went to rcpics.net where I usually download my pics, but this was the first video I have tryed to download. After I clicked "upload" it gave me a message of "Sorry, the format you have used is not currently being accepted by RCPics.net".

I downloaded the video to my computer from my cell phone (yes, very poor quality) so I don't know if that has to do with anything.
When I open it up from my computer, it opens with QuickTime.
The file type is 3GPP Movie Importer. What ever that means.

Is there a way to change the file type or another website where I can download it to that will accept this file type?
Thanks.
John
