I've tweaked
Juliano's script in order to let it work with the newer (and also 64 bit) version of ffmpeg.
For Windows users it's quite simple:
Download ffmpeg, extract, copy ffmpeg.exe from the bin folder
Make a new folder somewhere you like, paste the ffmpeg.exe in there
Make a new file (in Windows: right click > new textfile)
Edit the textfile, paste this in it:
Code:
for %%A in (*.m2v) do ffmpeg -i %%A -b:v 2000k -vcodec mpeg2video -filter:v yadif -s 640x480 %%A.mpg
erase *.m2v
ren *.m2v.mpg *.
ren *.m2v *.mpg
for %%B in (*.mpg) do ffmpeg -i %%B -vcodec copy -an %%B.m2v
erase *.mpg
ren *.mpg.m2v *.
ren *.mpg *.m2v
Choose File > Save as...
Set "save as file type" to All Files (*.*) in stead of Text Documents
Name the file daphnemaker.bat (or whatever you like, as long as it's .bat)
Now copy all .m2v files into this folder, make sure you use copies as originals are being deleted in the script.
Finally doubleclick your daphnemaker.bat, wait a bit and it's done!
