Deinterlacing vs IVTC

[x265]

Why is IVTC better than deinterlacing?

[feisty2]

If your source is telecined, then you should use IVTC because it's a total reversing process of telecining,it can restore your source back to the original 24fps theoretically
If your source is interlaced (not telcined,make sure not field blending too :)),then you should use a deinterlacer,the difference is it can not "restore" your source to progressive,it just makes your source "look" like progressive because there's no progressive information contained in your source

How do i know whether it's telecined? (the source is anime).

If your source is kind of 3 progressive frames followed by 2 interlaced frames,then it's usually telecined

I'm planning to IVTC a anime DVD which i bought recently. Which filter should i use for this?

TIVTC or AnimeIVTC (Mode=1) if it's typically telecined

what region was your dvd from? Like what country?

I'm sure we'll be counting the minutes.

If it's PAL (R2 doesn't mean much because if it's from Japan it's NTSC), then you don't IVTC. More than ever a sample is necessary. Maybe it's field-blended. In any event, deinterlacing is probably the wrong thing to do. Anime is not created interlaced (although there may be some interlaced sections, such as end credits and (rarely) some CG stuff.

Could someone explain me the working of IVTC? I read this guide http://www.animemusicvideos.org/guides/avtech31/theory-videointerlace.html but i still don't understand it

Section 2:3 Pulldown. IVTC is inverse telecine, therefore do opposite to pulldown tecnique.

First make sure you really understand "field" vs "frame".

Notice that the original frame "B" in that guide's example has been split across two frames, the odd field from frame "B" in the first and the even field of frame "B" in the second. IVTC pairs these two fields to create the original frame "B" and drops the duplicated fields which had been being displayed twice (the even field from frame "A" and the odd field from frame "C"). IVTC just needs to keep the other three original frames to give the you the original four progressive frames.

Here is the sample for the DVD (Batman animated series). Bitrate viewer shows it as 2:3 pulldown.

That's not a sample from the DVD. If it were it would be a VOB or M2V. That's been repackaged as MKV. Next time time use DGIndex to cut out a piece, one a bit brighter than that dark and hard to make out one you gave. Open a suitable VOB in DGIndex. Use the [ and ] buttons to isolate a small piece (we don't need a full minute). Then File->Save Project and Demux Video. Upload the resulting M2V.

It's progressive 23.976fps with soft pulldown. You don't even have to IVTC it, much less deinterlace it. Just make the D2V using Video->Field Operation->Forced Film. That will give you the D2V already progressive 23.976fps.

DGIndex shows it as Video -> 98% shouldn't i force film when it says Video type -> Film 95% higher. There are interlaced frames even after force film. http://img843.imageshack.us/img843/8562/bats010454.png

I was just going by the sample and running the Preview in DGIndex, which says it's progressive. Making a D2v and having a look shows that to be incorrect. You're right and thanks for the correction. My previous post about it being 23.976fps with soft telecine was wrong. Someone screwed up somewhere along the line. Then make the D2V using 'Honor Pulldown Flags' and IVTC it using the TIVTC like so:

TFM()
TDecimate(Mode=1)#Mode=1 for anime.

Should i set the PP as 6 or 7?

[manono]

I use the default post-processing in TIVTC, which is 6. With any luck it won't need any. The sample didn't.

As for denoising, the series is supposed to be sort of gritty and the noise is intentional, I think. Just a guess as I don't know that series. However, maybe the best denoiser is also terribly slow and is called MCTemporalDenoise. I'm partial to the FFT3DFilter, which denoises both spatially as well as temporally. Different people have their own favorites. A bunch are listed here:

[x265]

Should i just use the preset for MCTemporalDenoise or should i tweak the settings?

How do i remove this rainbow? I tried using LUTEDeRainbow but it is still present and it is not completely removed

How do i remove this rainbow?
See if using Checkmate works on it. Here are listed Checkmate and other Rainbow/Dot crawl removers:

I tried using derainbow and it looks terrible. The color looks washed out, checkmate didn't remove the rainbows.

Then I'm sorry to be of no help. Maybe someone that knows more about anime than I do will see your thread and give a better solution.
