[SOLVED]Uploading

Hey guys. I have just spent some hours editing a mw2 quick scoping movie that I was gonna put on youtube. So i went on my youtube account, pressed upload but then it said that it could take the file format that the movie was edited in, and it couldnt even get the music file format.. I have edited in sony vegas, the file is a .vf file, and if I could change that it'd probably fix the problem. But sony vegas wont let me!

Any help? /

How are you saving the file?

Hey, I'm just saving it basicly. I have tried to save as new format but Sony vegas keeps changing it back to .vf =/
