hey all.
im looking to add that little extra inch to my svcd picture quality. currently im using decomb and then smart deinterlace in vdub. if i try to add any filters (after that) in vdub.. it slows my encode way down in cce to the extreme. i was experimenting with Unsharp mask and Smart smoother HiQuality (filters) and it probably slowed me down by like 5x. any suggestions?
Thanks

Quick suggestion is to use Avisynth to frameserve instead.
Do any filtering with Avisynth.

i am using avisynth for decomb.. but for the few left over interlaced frames i used smart deinterlace in vdub to take care of them. wouldn't i want to only add filters after all frames are progressive? or are you saying that some how i could use smart deinterlace through avisynth?
Thanks for the quick reply

Hi-
Decomb's Telecide-Decimate combination has FieldDeinterlace turned on by default (unless you set Post=0). If you still have a few interlaced frames left over, you should be tweaking the settings rather than running the whole thing through another (VDub) interlacer. And as The Edge says, keep the whole thing in AviSynth, for speed, if for no other reason (and there are some other reasons).

thanks manono! =)
i appreciate the reply. i was using the following avisynth script:
LoadPlugin("C:\Decomb.dll")
AVISource("D:\Capture.avi")
Telecide(guide=1,blend=false,post=false,agg=true)
decimate()
So would u recommend removing "blend=false,post=false" <- those 2, and not use smart deinterlacer? But will this deinterlace all the frames?
Also, from your experience (or any1s) what else would you recommend me add (filter or otherwise) into my avs to improve my overall picture quality. there are so many different filters out there. any advice/personal opinions would be greatly appreciated. Trying to get the best possible quality out of my 704x480 tv capture.
One thing I'd like to correct with the picture: theres color fuzz/dots in solid regions but then blury around the edges of figures. This is why I was playing with Unsharp mask (sharpen filter in vdub) and Smart smoother HiQuality (smooth filter in vdub).
Thank you much,
I appreciate all the help
