Hey all!

I've spent a few hours playing with deinterlacing this afternoon because I've been ripping a bunch of my DVDs and just wasn't at all happy with the video quality.

However..... I stumbled on a new algorithm in LAV that does a wonderful job and just thought I'd share!

W3FDIF (Weston Three Field Complex) in LAV does a much better deinterlacing job than YADIF or MadVR. Thanks for adding this Hendrik!

MadVR deinterlacing creates too many combing artifacts for me but LAV w3dif is wonderful!

It really does make watching up scaled DVD so much less distracting and now I'm really enjoying my old movies instead of getting annoyed at deinterlacing artifacts!  Thanks again Hendrik you Rock!

Is it on by default or do you need to go into LAV settings?

There shouldn't be any deinterlacing artifacts if you're watching movies.
Set madVR to force film mode or tag the filenames with [deint=film]

You need to go with custom video filter and edit LAV settings instead of using ROHQ.

RD if only it were that simple with DVD.  There are a lot of bad DVD masters out there that have a number of problems that can confuse deinterlacers. Bad flags, things they get wrong: encoded as interlaced, encoded as progressive, sped up for pal with bad flags. Most of the problem DVDs in question are also video of rock concerts, not film. Hope this explains.  Also the deinterlacer in MADvr doesn't do very good motion compensation so I see heaps of deinterlacing combing effects where it can't do the required motion compensation.

Yes, for video DVDs the situation is different and I've yet to find anything ideal for that.
But for movies film mode should be free of artifacts.

how do you edit LAV settings?

You would need to install an "external version" of LAV (and not use the built in version).

Thanks...that's what I thought

A "madVR settings" option has been added to the Video/ROHQ section, maybe something similar could be done with the LAV settings? This way we could have both the nice automation of RO/ROHQ and the ability to configure LAV/madVR without having to install them externally, too.

LAV is fully automatically configured by MC, there are no settings to access, sorry. If you want custom settings, you need to go the custom route as explained here.
Note that the Hardware Deinterlacing used by MC by default is generally higher quality for the majority of content. A few badly authored DVDs may be an exception.
