Right. What you’re describing is exactly the benefit of what we call GOUT sync. However, I would say you do not need to trim the video (in fact, please don’t. Harmy and I put it there for a reason). Even in our releases none of the audio covers that 30 seconds and the tracks all have varying lengths, especially the commentary I believe. Vlc will show wonky run times if you fast forward to the last 30 seconds, but otherwise it’s not a problem.
If you do decide you want to trim the credits. I believe I can safely speak for harmy (and certainly myself 😛) when I say please just keep it for yourself instead of complicating things by distributing the unnecessarily altered version. 😃
