Hello,
I did a test encoding, with a small clip and used Avisynth for frameserving to CCE 2.5. Initially I used the TemporalSmoother from mpeg2dec.dll and the encoding speed turned out arround 0.8x on my Athlon 1200, 512 2-2-2 machine, which disappointed me a little.
LoadPlugin("D:\PROGRA~1\DVD2SVCD\MPEG2Dec\mpeg2dec.dll")
mpeg2source("E:\STARSHIP_TROOPERS\DVD2AVI_Project_file.d2v")
TemporalSmoother(2,1)
BilinearResize(480,432)
AddBorders(0,72,0,72)
~0.8x with CCE 2.50
Then, I removed the smoothing filter, but there was very little difference: it made the process approximately 0.2 faster.
LoadPlugin("D:\PROGRA~1\DVD2SVCD\MPEG2Dec\mpeg2dec.dll")
mpeg2source("E:\STARSHIP_TROOPERS\DVD2AVI_Project_file.d2v")
BilinearResize(480,432)
AddBorders(0,72,0,72)
~1.0x with CCE 2.50
But this was realy weird: I removed only the first line, which I realy didn't expected to have any big impact in speed for it self. But here's what I got:
mpeg2source("E:\STARSHIP_TROOPERS\DVD2AVI_Project_file.d2v")
BilinearResize(480,432)
AddBorders(0,72,0,72)
~2.5x with CCE 2.50
Now is this strange? A slowdown of 1.5x just because of the loaded mpeg2dec.dll - without using ANY filter from it? Is this normally?
