Convert with FFMPEG batch file

[Anoniempje]

Hi , havent been here in a long time , it sure has changed. Well I'm working on a batchfile where you can drop video files and they will be converted to g1 compatible files. Problem is, I can't get it to work.

I got the latest FFMPEG version (0.5) and XP pro ( if that is of importance to batch files)

ffmpeg -i %1 -s 480x320 -vcodec mpeg4 -acodec libfaac -ac 1 -ar 16000 -r 13 -ab 32000 -aspect 3:2 %1.mp4

The %1 is the input file, So if i drop video.avi on the .bat file it should name the output file video.avi.mp4 but somehow it wont work.
Any bright lads or lasses want to point out any errors in eith FFMPEG or batch syntax?
