interlaced lines in transcoded output

[onisama]

I've been trying to backup "Ah! My Goddess" the movie. It is a hybrid mix of about half interlace and half film. I've used DVDShrink, Instantcopy, and Recode2. All three show interlaced lines when viewed on my stand alone player. Will I have to encode and IVTC to get a clean picture?

What happens when you play the original? If the DVD is poorly flagged, then the original should have the same problem.

Anime is notoriously difficult to transcode correctly. Some is better than others. But the thing is to use a decent IVTC filter like Decomb which needs to be loaded as an Avisynth script. Most of these simple transcoders just cannot cut it when trying to transcode anime.

Huh? I disagree, quite a lot actually.

Anime sources are one of the hardest things to re-encode. Whacky telecine methods, hybrid footage, changing field order - there's a whole variety of things that can make re-encoding the footage a nightmare. It's true there are a lot of good tools out there, but for some anime, re-encoding is next to impossible. Ask any one who has tried to re-encode Lain or Neon Genesis Evangelion.

Transcoders, like DVDShrink and Recode, are the very best tools for problem anime, because they preserve all the information in the MPG streams that lets DVD players show the footage correctly.

I'm not saying the transcoders will fix a DVD that was authored badly (which sounds like might be the case here), but as long as you're not working with garbage-in, a transcoder is an absolute god send for backing up anime.
