TMPGEnc 4.0 XPress
We are now using the fourth version of this MPEG-2 encoder. Compared to the third version, the latest integrates a couple of optimisations for the Core 2 and improves performances by approximately 5%. For this test, we continue to encode a 10 minute 16 second DV file to MPEG-2 format in 720x576 with an average bitrate of 4500 Kbits in two paths. The video preview display is activated during this test and the DV file is decoded via a Mainconcept codec, which is faster than the decoder in TMPGEnc.
This time, the Pentium D 945 is a bit faster than the E4300. However, in both scenarios results compared to AMD's solutions are incomparable. Only the 5600+ provides comparable performances.
VirtualDub & DiVX 6.4
We use the 1.6.16 version of VirtualDub and the 6.4 version of DiVX. The latter improves performances by 8% with A64 X2, 10% with Pentium EE and 14% with Core 2. The same video is compressed as in TMPGEnc in Fast recompress mode, via DiVX 6.1 CODEC, in one path with an average bitrate of 1500 Kbits /s, b-frame and with best quality encoding performances. The video preview display is activated during this test.
