You can also try changing ‘-af’ to ‘-an’, that should remove the audio not just change its volume. If there are other videos with audio you want to keep then do the above in a temporary project and then replace the old file with the new one and select ‘Do not reprocess’.

Hint: You can copy and paste the video settings, like this:
-y=
-i=$inputPath
-vf=hqdn3d=1.5:1.5:6:6,scale=min(iw\,trunc(iw*min($videoWidth/iw\,$videoHeight/ih)*0.5)*2):min(ih\,trunc(ih*min($videoWidth/iw\,$videoHeight/ih)*0.5)*2),unsharp=3:3:1.0:3:3:0.0,$normalizeOrientation
-ss=$clipStart
-t=$clipLength
-threads=0
-b:a=96k
-ac=2
-ar=44100
-vcodec=libx264
-crf=$videoQuality
-metadata:s:v:0=rotate=0
-movflags=faststart
-pix_fmt=yuv420p
$outputPath=

It turns out that the sequence of the arguments makes a difference.

If you just want to remove the audio from an MP4, you can use the NoPages skin, which won't do anything else (i.e., no album is produced), and change the Video tab settings to match the attached screenshot.

Then you can use that video in another project, and let jAlbum process it along with all the others in the project.

I should have done that before, better late than never though
-y=
-i=$inputPath

Even easier :)
I have added the code I pasted above to the wiki page linked previously - it should be easier to find in the far far future.
