### MANUAL ###

1. Copy the abowe code and save it using your favorite editor as "my awesome converter.bat"
2. run it
3. Win

note* you have to have ffmpeg.exe in your system32 folder for this to work - download it from the official site

### DESCRITION ###

The converter exports all MP3 files (can be changed to any type: aac, wav...) from a folder where this script is located (to the same folder) to MP4 files (can be changed to AVI, FLV,...) with the image "picture.jpg" (can also be changed: png, gif...) provided.

### BREAKDOWN ###

%%i  - for every file with the given parameter (witch here is the mp3 files)
(*.mp3) - any file with the mp3 filetype
do ( - starts the command:  ffmpeg -i picture.jpg -i "%%i" -c:a copy -vcodec libx264 -pix_fmt yuv420p "%%~i.mp4"
ffmpeg - starts the ffmpeg.exe converter with the parameters:
-i picture.png - "-i" inserts a new file, wich here is the picture we want
-i "%%i"  -  inserts a new file, wich here is the first in order of files from the folder, and than starts the next one...
-c:a copy  - uses the same encoding ("a" stands for audio, "v" for video - but we have a pic, so we don't need that) as the file provided (better coz it needs less time to convert the file)
-vcodec libx264 - (forces the video exported to have the 264 video codec)
-pix_fmt yuv420p - google it, but you will need it xD
