[John P. Mitchell]

All,

   Thanks to the devs who added batch export to nuvexport. You guys did a
great job.

   On the speed side of things, I have tried several machines to see what
difference that made on the process. I setup my XBox (733MHz
Celeron/PIII Hybrid) running Xebian and I got around 7fps exporting
640x480/2200kb video and 192kb/mp3 material to VCD without the denoise
option. With the same exact material on an Athlon XP 2000+ I got about
10fps. With my brand spanking new Athlon 64 3000+ I get about 15fps.
Anyway, usually takes about two hours to export the material. Something
about this seems wrong. Especially since my friend transcodes material
on his windows box with several different tools and gets about 33fps.
Also, I see benchmarks on various websites for hardware almost exactly
like mine that show some amazing fps for converting AVIs to DIVX/MPEG
in Windows:
http://www17.tomshardware.com/motherboard/20040420/nforce3_250gb-18.html.
So what gives? I know it is not nuvexport, so it must be transcode. And
thinking on it for a moment tells me that if my box can decode the
content without breaking a sweat then it should be able to at least do
the transcode realtime. Anyone have any insight into this? I am
starting to think it might be worth rebooting my box into Windows XP
just to get a decent transcode time.
