Mainconcept MPEG-2

Mainconcept MPEG-2 encoder is about 1/1.5=2/3 or 67% faster then TMPGEnc. The following table shows encoding times on D600 of 8 minute PonPom movie

Method	Time	PSNR Y
TMPGEnc 2pass 6Mpbs	1:28:13	33.4125
Mainconcept 2pass 6Mpbs	0:59:18	15.0318
x264 2pass	1:12:18	32.232

As could be noticed from the table PSNR of Mainconcept encoded MPEG-2 is significantly lower and noticably Mainconcept encoded MPEG-2 has sharper interlaced (mouse tooth) artifacts. Overall, Mainconcept suck and not worth the time.

What is surprising is that MPEG-2 encoding is so slow... Even Mainconcept does it in 1/7 = 0.13 real time or at 4 FPS while TMPGEnc at about 3 FPS....

x264 does 2 pass encode at 1/5.25+1/3.58 ~ 1/2 or at about 2 FPS with all the processing (deinterlace, resize, change framerate to 20 FPS), but since there is less frames it is actually faster then encoding to MPEG-2 with TMPGEnc
