There's no particular reason -vf shouldn't work in a while loop. It's just very tricky to get all the quoting and escaping right. Shove printf "\t%s\n" in front of ffmpeg to see what its really doing - it will print each separate argument on its own line. You'll be able to tell if your quotes broke somewhere.

winff

WINFF(1)																  WINFF(1)

NAME

       winff - video and audio batch converter using ffmpeg

SYNOPSIS

       winff

DESCRIPTION

       This manual page documents briefly the winff command. This manual page was written for the Debian(TM) distribution because the original
       program does not have a manual page. Instead, it has documentation pdf format; see below.

       WinFF is a graphical user interface for the command line video converter ffmpeg. It runs ffmpeg from the command line. So, you just pick
       your files and it does the rest.

       WinFF doesn't actually convert any video files. It just runs ffmpeg. Therefore, It will convert any video file that ffmpeg will convert.
       Conversely, if ffmpeg will not convert the file, then WinFF will not either.

SEE ALSO

       For more details, you should have a look at the pdf manual, available at /usr/share/doc/winff/winff.pdf
