Not to be unkind, but have you read the man page for ffmpeg?

-f fmt (input/output)
     Force input or output file format. The format is normally auto detected 
for input files and guessed from the file extension for output files, so 
this option is not needed in most cases.

If you call the output file fred.mp4, without saying otherwise you're going 
to get an mp4 file.

Please read up on all of the options you're using- for instance, -vf without 
a filtergraph is meaningless.
