Shell script using FFMPEG convert to mp4 results in new video with .mp4 extension attached twice

I am converting an entire folder of videos to MP4. The script works except that the new videos have ".mp4" attached twice to them. For example. 'video.mp3' would be 'video.mp3.mp4' after conversion. Below is the shell script. TIA

#!/bin/bash
#Shell Script which converts all videos in a folder to MP4


for file in *.*; 
    do 
        if[ ${file: -4} != ".mp4"]   #don't want to convert mp4 files           
            ffmpeg -i "$file" "${file}".mp4 
done

This will strip the last file extension: ${file%.*}

So you'd want ${file%.*}.mp4

Here is a good reference for string manipulation in bash: http://tldp.org/LDP/abs/html/string-manipulation.html
