3) Progressive footage encoded as 'interlaced'

Postby sparky_3150 » Fri Apr 10, 2009 12:25 pm

So I've been going through the AMV guide, and I realise that my DVD falls under category three, which is as below (quoted verbatim from Read ErMaC & AbsoluteDestiny's Friendly AMV Guides):

3) Progressive footage encoded as 'interlaced'. This is where you have footage which doesn't look like it has any interlacing at all but DGIndex has told you that every frame was encoded using Interlaced encoding. This means that the footage was encoded one field at a time even though both fields are part of the same frame. This isn't a problem, really - you can still encode and edit it progressively. This often happens with PAL encodes of movies. The only thing you need to be careful about is whether the chroma channel is sampled correctly when doing any colourspace conversions. I'll show you how below and, thankfully, it's rare for this to be necessary.


It says "This isn't a problem, really - you can still encode and edit it progressively". Now what does that mean?

Do I have to undergo any inverse telecining? Because with the AMVapp saving the project in DGIndex automatically creates an AVIsynth notepad script, do i have to write in anything inside that script? (i want a progressive picture btw). Or do i simply go into adobe premiere pro and say "use progressive scan"? Or do i say in premiere that the footage is interlaced? Or do I write in something in the script to make it progressive (remembering that it looks progressive anyways, but DGIndex says it is interlaced)?

What do i do i'm quite confused, and this third situation seems rare.

Any help would be most sincerely appreciated.

You just treat it like it was progressive encoded as progressive.
So yeah, the script doesn't require any deinterlacing or ivtc and you just use the progressive scan in premiere. ;)
