is there a muted video snaps pack?

[fukc]

i have the video snaps all muted through bigbox already.  seems im wasting hdd space with audio tracks included in so many little gameplay videos.

Easy enough to get handbrake involved, but is there an easy option to strip audio?
.. like a checkbox I'm overlooking in EmuMovies Sync that's right below "Remove fade in from start of video"?
(It's not there btw. where's my sarcastic reverse italic typeface at you internets?)

cheers!

Most front ends I have played with give you an option to mute the videos.  Would be better than reencoding the bunch
