More TMPGEnc XPress Benchmarks

This is a follow up to TMPGEnc 3.0 XPress Encoding Times.

Playing with the noise reduction features in TMPGEnc a bit more. Specifically, the Spatial NR Setting and the Temporal NR Setting. This is just a first pass. I encoded 33m40s worth of footage using the following settings:

Spatial 20/small Temporal 20/small - 2:10:25 - 3.8x
Spatial 30/small Temporal 30/small - 2:14:33 - 4.0x
Spatial 50/small Temporal 50/small - 2:10:40 - 3.8x
Spatial 75/small Temporal 75/small - 2:14:18 - 4.0x
- these were all within margin of error of each other

Spatial 20/medium Temporal 20/medium - 4:21:42 - 7.8x
Spatial 30/medium Temporal 30/medium - 4:17:00 - 7.6x

Spatial 20/large Temporal 20/large - 6:34:50 - 11.7x
Spatial 30/large Temporal 30/large - 6:39:20 - 11.8x

Changing the size / duration of the spatial/temporal filters had the biggest effect (as expected). CPU utilization on my dual-Opteron 246 system was not always 100%, so you should set the bach encoder to process 2 projects at the same time on a dual-CPU machine.
