Interlacing Issues

[AnnaMayBelle]

So far I've made several videos on my own, but one thing has always bothered me... Interlacing. I never saw it in professional AMVs, and it's always bothered me that I saw it in mine. But every time I've tried to figure out a way to fix it, FAQs have always been confusing or didn't apply to the methods I use.

Basically, I'm not working with AVS or anything. When I rip my footage, I end up with raw, 100% uncompressed, no-audio AVIs. Yes, they're huge, but I have the space to deal with it. Right now, I'm specifically working with the Evangelion TV series. I've read "A&E's Technical Guides to All Things Audio and Video"... and while it's a wonderful FAQ, I still need just one thing answered.

What is going to be the best deinterlacing method for my specific situation?

I know, it sounds like a newbie asking for the simple method to be handed to them on a silver platter... But really, while I've been making AMVs for over two years now, I am by no means a video expert. Any assistance would be much appreciated.

Use AVS.

You can solve a lot of problems that way.

What is going to be the best deinterlacing method for my specific situation?

If this is the original Eva TV DVD set (i.e. not Renewal), there's pretty much no easy fix. Many suggestions have been given. Few actually work. Even fewer actually work well.

One thing I found to work somewhat well (in times Way Back Then) was to run SmoothDeinterlace and keep the framerate at 29.97fps. I'm not sure what possessed me to try to get the framerate down to 23.976fps in "always"; it obviously didn't work. But, hey, what the hell.

This is going to sound like a copout, but I really suggest that you carefully read and re-read the following sections of EADFAG:

Full field / half-field blended fields and recognition thereof
http://www.animemusicvideos.org/guides/ ... etb2a.html

Blended field situations - restoring progressive frames
http://www.animemusicvideos.org/guides/ ... etb3a.html

It's been a while since I've seen the original Eva TV release, but I recall it being half-field blended to hell. Someone who has worked with it more recently will probably correct me.

Regarding NGE, I personally never had a problem with just straight IVTC, though for some reason it worked better with Decomb for AVS2.0 than it does with Decomb for AVS2.5. Sure some of the frames are blended, but so what? It removes the interlacing, and that's all I care about.

Back-matching was enabled by default in Decomb 4; it's disabled by default in Decomb 5, as it had a tendency to produce jerky motion.

If you re-enable back-matching, you might get better results.

...problem being I don't want to start over a heavily timing-oriented video that I'm about half through with.

Trythil, tell me more about this "SmoothDeinterlace"? Is it a program, an option I haven't found somewhere, or what?

I read this and it makes me wonder if you have the problem that you think you have. If you watched "professional" (in quotes because I'm not sure what you mean by this) AMVs on a TV, then you saw them interlaced. Everything that plays on a normal (non-progressive, non-hi-def) TV is interlaced. And even with our amateur AMVs... all entries to AWA, for example, were converted to interlaced 30 fps MPEG2. And I'll bet they were played in interlaced format, too (through the analog output of a Netstream 2000, to be a bit technical).

If you have a specific problem, maybe we can help with that. It might be easier than switching in mid-stream of a project. Sometimes editing software has built-in deinterlacing (e.g. Vegas). Probably not as good as what is being suggested above, but it may work for you.

...Well, this is going to be a learning experience then. I've never worked with AVISynth before. The programs I use are SmartRipper, DVD2AVI, VFAPIConverter, then Virtual Dub, in that order, to get my AVIs. Which of these programs will AVISynth be replacing, or is it going to be another step added onto the end of my current process?
