Hi Brian, Is there another process in your pipeline that could be causing the slowdown?
In my personal experience, the raw MPEG encoding speed of an Athlon 700Mhz is around 30fps for VCD resolution with default encoder settings. There are some benchmarks at http://klicman.org/altivec/ if your interested in more numbers. -James On Sun, Dec 29, 2002 at 06:47:58AM -0500, [EMAIL PROTECTED] wrote: > On Sun, Dec 29, 2002 at 12:14:47PM +0100, Andrew Stevens wrote: > > > > What kind of CPU are you using. > > 800MHz Athlon ThunderBird.
