It's apparently not true. I had the same reaction at first to Mirkosp/MisterHatt on this very subject. "But I have projects from five years ago still using AMVapp 2.1."

"It doesn't matter.

"Oh."
Anyway, the footage was still interlaced, it just seemed a little better in some way. But either way I went ahead and just used AMVIVTC(mode=1) to try it out and that took care of it. There is a little bit of a minuscule jitter that shows up here and there among single frames, but nothing bad. I'm not sure if it's something that can be handled with any more scripts, but it's not particularly necessary as it's barely noticeable. If you have any ideas what would be happening there I'd like to hear them, but it's not particularly important I would think.

What was the intent with all the more complex stuff you had me use before the initial guide's version? I didn't recognize most of that code from the guide, I'm just curious.
MisterHatt is a professional encoder and knows a ton of shit above and beyond what is in the guides. His intent was to help you out (because it was very late where I was, and I was tired, and wanted to go take a nap). If he is in a good mood, he can probably help refine what you have working now. Otherwise Mirkosp can. I myself am mostly a point man and getting your basic scripts running, especially for the mac editors, but I am far outclassed by others when it comes to individual, up to date commands.

It was late for me when I wrote that Kio, my timezone is only an hour behind yours.

As far as script complication goes, what I suggested was far less intense than AMVIVTC. AMVIVTC is, iirc, just a renamed AnimeIVTC with a few minor changes, and is a long complicated script that is meant to automagically figure out what sort of content you have. The line I provided however is designed specifically for poorly encoded pure-telecine footage. I didn't know what you had and it might not have been appropriate, but as it's a movie I'll guess that it's either VFR in which case lol at AMVIVTC, or it has shifting patterns or some hybrid material, R1 movie DVDs liked to do stuff like that a few years ago. I don't think my line can be refined further to be more correct without having seen what kind of content you have, although that stuff with clip2 and emask/edeint would prevent all the minor jitter you're getting if the field matching was correct, which it seems like it isn't. If you could provide a screenshot or several of what you mean by it still being interlaced, maybe I can hazard a guess, but if you're happy with the AMVIVTC output, then leave it be.

Far from that. It's just a few "presets" for tfm + tdecimate, really.

Orly? Even worse, although not as adaptive I guess. What exactly is mode1 in it?

Checked up on that script (thanks pwolf), and... wow, yeah. That's just ugly. Far from adaptive, I can't really see how your source would be 'interlaced' after using my line but not after AMVIVTC mode=1, which is essentially the same thing but less refined and with a less effective decombing algorithm. Provide a screenshot of the comparison if you can.

I'm sorry, I already overwrote it with the new footage (space problems), but I can basically describe it as what I glanced at before deciding it hadn't worked was basically the interlacing around the mouth movements that I was looking for had turned to skin color rather than being darker, almost like a reversal. I know that doesn't help much, but I probably misinterpreted what was happening. All I know is it wasn't much of an improvement if at all, so I just wrote it off as it hadn't worked and tried something else.

I don't think you misdirected me or anything, stranger stuff has happened in my work. I work in 3D Animation a lot and many times things that should work don't and something simple solves everything, I just can't seem to understand the programming side of anything. Annoys the hell out me that my mind doesn't wrap around it. Granted it's not my focus, so I haven't truly put my all into programming before, but that's also because I know it's something I just don't like doing, so... :(

Sounds like your field matching order was off is all, that or pp was doing weird things.
