A quick deinterlacing query

[Raiders]

Hey all,

I'm attempting to rip/encode my Futurama season DVDs (NTSC, Region 1). I'm encountering a slight problem in this process, and while there're several solutions, I'm unsure which is best.

I'm using the latest Gordionknot for this process.

The problem involves the composition of the episodes. Namely, they're about 98% film, so I'd prefer to encode them at ~24FPS if possible (i.e. Force Film 'em in DVD2AVI). Irritatingly, however, there're a few NTSC frames sprinkled about the episode, which show up as having interlacing artifacts in the final product.

My question: what's the best way to get rid of these artifacts while keeping the frame rate at 24fps? I guess I could just run the entire shebang through a deinterlacing filter while encoding, but wouldn't this lower the quality of the encode? I'm not very adept at editing the Gordionknot-generated Avisynth scripts...is there any way of telling FieldDeinterlace to just affect the interlaced frames? Are there decimate/telecide functions I could use?

TIA,

-R

Have you looked at www.doom9.org/ivtc-tut.htm yet? There are some discussions there on ways to handle hybrids, though the content is a little bit dated (the Decomb filter has been updated since).

If you download the complete Decomb package (http://www.neuron2.net/decomb/decomb521.zip) you'll have access to the manual. It describes every parameter of Telecide/Decimate, and includes a separate section on hybrid management (Appendix B).

I have, but it isn't entirely helpful. I'm something of a newbie when it comes to this--I can get things done, but not always optimally. I understand what they're saying, but that doesn't translate into knowing how to do it.

I noticed that. So I should leave Force Film off and allow decomb.dll to handle everything?

That is how I usually handle small, one or two frame sections that are out-of-Telecine sequence. ParseD2V can tell me which frames to examine manually.

I look at the results via previewing, by opening the .avs in VdubMod, and adjust Decomb parameters iteratively, before encoding.

Thanks for the advice.
