But perhaps there's someone left who's experienced with video rendering.
I used the normal Sony Vegas Default Template for my last Videos but compared to the Quality of this two-pass rendering its shit.
I just do have one problem:
90 mb for 2:36 mins with default Sony vegas, 331 MB with this way.
Anyone an idea how to minimize my file?
And I don't see how this two pass rendering reduces the file size ;)
Higher quality is going to mean larger file size. It shouldn't be that big, though. Approx. 25 megs \ 1 minute length is good, and iirc the WarcraftMovies requirement, which this method meets.
There's two ways to reduce size:
First) Don't skip the VirtualDub portion (if you did). The compressed audio will shave a non-trivial amount of size off the file.
Second) If you've already done that, re-render with a lower bitrate. Anything > 3,000 kbps is a waste as it inflates your filesize with no quality gain. You can also safely go below 3,000 and still have very good quality. I believe I used something in the ~2,400 range when I was making videos and had great quality / filesize. Your mileage may vary. You should probably just render a few 1 minute sample clips to get a feel for what bitrate you can get away with.
Third) Don't fraps above 30 FPS. You probably aren't doing this, but if you are it will significantly increase the file size of both the raw and final output clips.
