Updated MP4 to MP3 Script

Wanted to add some metadata to the mp3 I created from mp4s.
so. But for some reason yet to be investigated windows 8 cant seem to find my metadata.
VLC is happy.


REM FORMAT REQ <name-nospace><space><minus><space><songname><.mp4ext>
REM EG 'coolkids - i like to rock.mp4'
for /f "tokens=1,* delims=-" %%a in ('dir *.mp4 /b') do (call :makemusic %%a "%%b")
goto :eof

:makemusic
set str=%2%
set artist=%1%
REM %str:~2,-5% is used to strip the quotemarks and filename
set title=%str:~2,-5%

REM UPDATE WITH YOUR CORRECT PATH TO FFMPEG
G:\music\ffmpeg.exe -i "%1 - %title%.mp4" -vn -ar 44100 -ac 2 -ab 192000 -f mp3 -metadata title="%title%" -metadata artist="%artist%" "%1 - %title%.mp3"
REM <need command that will allow normalise the sound levels> :eof

ffmpeg speed, scale and cut\split

Speed it up
ffmpeg.exe -i "mevideo.mp4" -an -vf "setpts=0.1*PTS"  lols.mp4
scale 50% and cut\split after 127 sec
ffmpeg.exe -ss 0 -t 127 -i Lols.mp4 -vf scale=iw/2:-1 test1.mp4

should of done step 2 in 1 go, but gave my cpu something to do..

batch ffmpeg convert mp4 mp3

Not my best FOR loop, quick and nasty.
Had a stack of mp4 videos to convert for the ride home.

mp4mp3.cmd <batch file>

for /f "delims=." %%a in ('dir *.mp4 /b') do G:\music\ffmpeg.exe -i "%%a.mp4" -vn -ar 44100 -ac 2 -ab 192000 -f mp3 "%%a.mp3"
