What software are you going to use? What codecs / containers? The P4 wins only if the applications, codecs and containers are very well optimized for HT / SSE2. Otherwise it will lose.
Most of the consumer grade software runs better on AMD hardware (Roxio, Ulead, Sonic) with the exception of Pinnacle 9. Ulead video studio 8 is by far the fastest, and runs even faster on AMD
Most of the midrange software run better on AMD hardware (Ulead Media Studio Pro, Vegas) with the exception of Adobe premiere 7.0 and pro. Older versions of premiere run better on AMD hardware.
MPEG-2 encoders is closer, some run better on AMD hardware (Canopus, ligos, CCE) while others run better on the P4 (mainconcept, tmpgenc) . CCE is by far the fastest and highest quality, but it is expensive.
For AVI encoding to DivX, some run better on AMD (DVD2AVI, virtualdub) while others prefer the P4 (XMPEG, flaskmpeg). DVD2AVI is the fastest for DVD -> DivX while virtualdub is the king for basic edition.
I don't know about DVD transcoding (DVDshrink, Nero recode) but I assume the bottleneck will be the hard drive
As far as codec / containers DivX runs generally better for the P4, XVid runs generally better on AMD. Quicktime prefers the Athlon, while WM9 in general prefers the P4, but on ASF container it is more evident than using AVI (WMV) container. I don't know about real video, but I suspect it prefers the P4 given the close relationship between real and intel.
By the way,
DV edition and rendering runs faster on AMD hardware , but the hard drive is vital. Keep in mind also that developers have to meet deadlines to bring a new product into market, so if resources are tight, in many cases they will have to choose between features. "Picture in picture" will be a much better selling feature than "P4 and HT optimized", so don't lose this fact from sight. More likely that not the application won't be extremely tuned for the P4.
Comments welcome
