I've read each topic 1000x and re-looked to try and help myself out with this first. I really need help rather than a general link to a guide with 100 different topics

See 2nd topic of the guide:

You do NOT deinterlace usually.

To answer your question bluntly though, you can deinterlace in AVISynth by adding the following line:
Bob()

However I would never do that in a million years...

1. You DO usually want to deinterlace when reducing the resolution by half or else the resulting product won't be as sharp/clear and ghosting will occur.

2. Bob is the shittiest deinterlacing method EVER

Anything else?

The only reason you would want to de-interlace is if you're using interlaced footage.

Telecined footage is interlaced. I believe DV footage is also interlaced.

You DO NOT have to de-interlace your video so long as you do IVTC.

If you do not do IVTC on your footage, then you'll want to de-interlace.

I would recommend grabbing a smart de-interlacer as those usually look prettier. But your best bet, is to just IVTC your footage if you can.

theres no excuse for not ivtcing :P but ermac has said before that tomsmocomp is probably the best deinterlacer out there. As for bob well, I think its the best way to deinterlace truly interlaced material since that way you at least keep the 60hz framerate thing going, by blend deinterlacing you're effectively losing the resolution and framerate, thus losing both the advantages of interlacing. Only thing is videos come out at 60fps, but thats not so bad considering while there are double the frames, they are also a good amount more similar and thus will compress better with interframe compression. Of course that only applies to true interlaced material, which is hard to come by

I'm going to have to disagree with you on this one. Tomsmocomp is a very ugly deinterlacer. In a head-to-head with every other avisynth deinterlacer I could get better settings in FieldDeinterlace and Smooth Deinterlacer. the latter is probably the best-all purpose one I could find.

Tomsmocomp creates noise when it doesn't detect things correctly (as Donald pointed out) and only doesn't look ugly if you blend fields... which is pointless anyway.

Certainly for anime I've found it less than satisfactory.

My previous recommendation was for VIDEO sources. I believe I mentioned TomsMoComp in that thread where the guy was trying to figure out that football thingy.

For deinterlacing Anime footage, smoothdeinterlacer and fielddeinterlace are, as Ian said, the best ones to use.
