Im sure at least something happens. ffmpeg provides some console output
which should show you some warnings. Please provide us with this
console output, uncut, so we can see what the issue is.

Parts of your command line are not (or no longer) supported. I.e.
> -ss %3 -t %4
won't have any effect, ffmpeg should warn:

They need to be placed *before* the output file they refer to.

Technically, there shouldn't be much of a difference, and apart from
the order of options, your commands could work. Console output will
help us.
