As soon as I finish my current video, I would be glad to help. How long will this be going on?

Until I release I guess.

There's a couple of versions of programs which are in the process of being updated (such as dvd2avi and xvid) that I'd like to wait on final releases but that wont change the operation of things.

So yeah, it's going to be a week or two before final final release I'm guessing.

Yes, basicly I meant YUV 4:2:2
However, the thing is if you convert interlaced footage from YUV 4:2:2 from whatever source to YUV 4:2:0 (YV12), the interlacing gets messed up because you have 4 luma and 2 chroma samples per line so 2 lines will share their chroma information.
Could be that it wasn't eternely correct what I read, but when I tried using Avisynth 2.5 for my DVDs that was the result

This is what it should look like:

I even specified the field order in mpeg2dec3, but it didn't help.
After I typed the line YV12toYUY2() under the mpeg2source command the interlacing was correct again, therefor I believed DVDs are YUV 4:2:2

Hopefully the new guide will clear things up, there's alot of false information about colorspaces floating around in the internet

2) "Jaggy pans" will depend massively on the decimation method and pattern guidance. Decomb 5 has lots of methods for all sorts of footage types - there is no 'one setting suits all' so you need to be careful about which options you choose.

If, for some reason, you don't like the new decomb you can actually use this command

loadlegacydecomb()

Which I included inthe amvapp. It will do things exactly the way they were in the old amvapp.

Cool, I tried out a few options with field orders and none worked so far, so I just need to tweak things abit I guess ^_^

What you are talking about is upsampling and it's not a problem with YV12 it's a problem with converting YV12 to YUY2 or RGB not the other way around.

DVD footage, as I have said already, is YV12. I talk about this at length in the guide so until that is published can we keep this discussion to be on the AMVapp please?

Alright well, I'll try this all out after work tonight. I've got everything installed and ready to go... but no DVD-R drive. I could always install my drive on this compy, if you want. But if it's no big deal, I'll just test out other stuff.

OK There's a confirmed bug for Win98. One of the avisynth plugins that comes with the AMVapp doesn't like win98, so will have to be deselected.

I just need to work out which one

Woohoo! win98 bugs squished thanks to the mighty atom!

I need to compile a new version but I think I should be able to get most of these bugs ironed out in the next release candidate.

does the new AMVapp incliude the fplugins for AVIsynth to work with Primiere 6.X and Pro by any chance? Just wondering.

Avisynth is upgraded to 2.x I assiume also?

If so I definately want to betatest it, as I have Primiere Pro, and remember all the problems I had with the previous one. So I'd be able to comment on if this one is easier to get working, or better yet works right out of the box ^_^
