im trying to keep as much picture quality as possible in my tv caps. my caps are 720x480 (29.97fps) which i resize down to 512x384. im trying to determine my best route for deinterlacing and keeping the most quality..

ive seen a few different interlacing settings in vdub.. ive played w/ most all of them but am not sure which is best for quality..

(from the settings ive seen: )
Should i add a de-interlace filter (like blend) or one of the others (if so which)?
When i resize should i check the "Interlace" box?
In xvids configuration settings under Global, should i check the box "Enable interlacing"?

^ should i do one (or some mix) of these settings or try something different?

Thanks

NTSC clips have to be IVTC'ed, not deinterlaced
I suggest DeComb or similar avisynth plugins for that.

If you capture movies or anything that is shot on film, you should IVTC. If your captures have originally been shot on video (news, sports, etc.), you should deinterlace. IVTC/deinterlace first and resize after that.

thanks guys for the replies! :)

i used "smart deinterlace 2.7 beta2" first and then resized "512x384 (Precise bicubic (A=-0.75))"

the results looked pretty good.

im capping from NTSC (US) Digital satellite. would i be better of sticking w/ the above.. or should i IVTC?

Thanks guys
i appreciate the help :)!
