I think this post doesn't fit exactly in the thread of CEE speedtest, so I post it aside.I appologise if I'm wrong.
The Story:
I've been recently doing some old VHS (PAL anime) to DVD conversions, using CEE 2.67 trial and a very simple AVS script:
Video=avisource("C:\CINE\Erase22.avi").Trim(614 ,163127)
BilinearResize(Video,720,576,6,4,708,566)
_2DCleanYUY2(Video,0,16,2,2,0,16,16) #really bad picture quality
The video was captured with a Hauppage Tuner Card, PicVideo jpeg (Q=19) and a resolution of 720x576.
I was using mostly Doom guide (Thanks a lot ) for CEE encoding parameters so: One pass VBR , Q:60 BitRmin: 1500 BitRMax: 9000, No Quality settings, The TMPgenc CG/animation matrices, and zigzag+progrssive flag. The Encoding speed obtained in a P4 3GHz hyperthreading computer was 0.56-0.60.
But trying to improve the picture quality I added the XSharpen() filter to the end of the script and to my surprise the speed went up to 1.09. Curious I tested others filters and finally found that with the TrBarry's Unfilter (), the speed rose to 2.20 with a better (to my eyes) quality!!
That's for the story.
The Request:
I thought that adding more filters to the processus the encoding speed should decrease, but maybe it's the filters chain order or maybe i'm doing something dumb because my limited experience. Perhaps somebody wiser can enlight me and explain this behaviour deeply.
The Thanks:
Anyway Big Thanks for the Guides, for the great filters and for the help from all you people :D
