Re: Faster encodes with WME using Advance Profile

Hi, all. I searched through all the messages for 2006 looking for an answer
to my question, but I didn't find it, so here is my question. First a little
background. I have an Athlon 64 3500+ processor with 1Gb memory. I am using
the on-board video as I do not have a dedicated video card. I have recently
experimented with using the Advance Profile with VC-1, and have found the
results stunning over the Main Profile with WMV3. Using the same value
quality VBR encoding for both profiles, I was able to encode a 43-minute clip
with a 31% decrease in size and visibly better quality with the Advance over
the Main profile to boot. Naturally I'm thrilled, but the downside of this
is that the encoding time has increased approximately 5X! Short of getting a
faster machine, are there any tricks I can do to decrease my encoding time?
Will getting a dedicated video card--preferably one that supports VC-1
acceleration--help? Oh, if it matters, I'm using WME 9.00.00.2980. Thanks
in advance for any advice.


In my tests, the WME Studio encoder performed with about 15-30% faster
rate than equivalent settings in WME. It benefitted from overclocking
the GPU and graphics memory subsystem in a way I've found hard to
explain why.

As you've noticed, AVC and H264 are computationally intensive to
encode, and to some extent to decode too. However it might be worth
knowing that product can only accept uncompressed AVI and WMV/WMA
input currently, so even DV-AVI isn't available as a source. Worth a
look though.
