Cyberlink PowerDirector can do it with a single click. It also seems to do this type of editing much more easily then Premiere Pro. I'll give it more of a test tomorrow.
Could you try something like exporting the audio, running it through something like the Levelator, and then reimporting it?
I've been looking into PowerDirector because it seems
much easier to use for this sort of work (ie. take a load of video clips, trim start/end of each one, put them in a sequence, single-click to match the audio levels across all the clips).
Looks like I still have compress it as a separate step to get it
really loud but that's quite easy to do as well.
Plus it's only 80 bucks.
Edit: If you search google for "cyberlink coupon" it comes up with "10POFF" for a 10% discount at their store.
So...what happens if you type "20POFF" instead? Yep, 20% discount...
(I tried other numbers but nothing else seems to work :-( )
Edit 2: Plus... it encodes video over six times faster than Premiere Pro. No doubt about it, I'm switching to PowerDirector.
That was the way I used to normalize the audio in Sony Vegas.
So Sony Vegas can't do this either?
Is it just me? This seems like a very basic requirement....
