Best way to deinterlace DVD animation within ffmpeg?

[mzso]

Hi!

I want to encode an animated series form the originial format of the DVD, to AVC (maybe HEVC?).
What's the best way to deinterlace?

rule 12.

is it even interlaced not telecine or a mix of both?

Half of this forum appears to be dedicated to anime and their deinterlacing.

I am sure the OP will find the right answer therein.

huhn made the correct response.

Post a sample - 10 seconds or so direct from the source - so we can have a look and decide how it should be treated. If you don't know how already, DGIndex can cut an M2V from the DVD.

The very beggining of it can be interlaced but Mediainfo does not scan all the file. It can switch to progressive or some other form of cadence, even 8:7 cadence for anime. There is no simple way to deinterlace, detelecine and decadence it.

If you can't be bothered to look at the video stream and figure out what horrible things were done to it and the best way to fix them, and you're just looking for a one-size-fits-all solution that can convert even the most pathological kinds of content into something that looks like what you'd see on a TV screen, then try this:

mpeg2source("blahblah.d2v").tfm(mode=0,pp=0,micmatching=0).converttorgb(interlaced=true)


GeneralConvolution(0, "
0 1 0
0 2 0
0 1 0 ")

GeneralConvolution(0, "
0 -1 0
0 6 0
0 -1 0 ")

However, this assumes that the source was intended to be pathological (retrograde field behavior and such). If there are blended frames due to incorrect frame rate conversion, then you're in a whole other world of shit.

Even 10 seconds isn't enough. Have you ever looked at the Captain Planet DVDs? Some of it is straight film with soft telecine, some of it is film with hard telecine, and some of it looks like it was captured from VHS tapes that had been left in a car's glove box for too long. It changes not just from one episode to another, but within each episode.

Even 10 seconds isn't enough.
Sometimes it is; sometimes it isn't. While anime can be difficult, the majority follow the 'rules'.

The fellow asked a generic question using the incorrect term 'deinterlace'. A request for a generic untouched 10 second sample (never provided in a 2-year-old thread) was the right answer.

ffmpeg doesn't has the best filter. My suggest is qtgmc, which is available in hybrid.

Not correct, the ffmpeg filter is best. QTGMC modifies by default both fields and thus is wrong.

[kolak]

Which ffmpeg filter is 'best' for it ?

[Sharc]

Not correct, the ffmpeg filter is best. QTGMC modifies by default both fields and thus is wrong.
Use QTGMC(lossless=1) to keep the fields intact.
