suggestion regarding filters interlaced vs progressive

[Insomniak4700]

how about adding filter options for both interlaced and progressive sources?

some filters don't work well on interlaced material, this could be useful!

I know it can be done in RB-OPT, but this would be nice to add in RB (to be able to use the one click mode)

I'm not sure I understand what you mean. DVD Rebuilder recognizes interlaced material and automatically adds the extra parameters needed for it.

[Insomniak4700]

Sorry I wasen't clear.. or I don't understand the feature correctly.
I'm talking about the filter editor window...

For interlaced material (let's say extras) on some filters, you need to do a separatefields(), -filter-, weave(). But this woudn't be too good for progressive material, am I correct?

Now since Rebuilder already scans for interlaced vs progressive material, it would be nice to be able to add a few extra lines in the AVS files when interlaced material is found. I think you already do this automaticly for the "Deinterlace with Decomb" feature...

[jdobbs]

Oh... I see. Yeah, that could be a problem for filters that have special settings for interlaced or progressive sources when the filters specified are applied to all.

Hmm... let me give that some thought and see how might be the best way to deal with it.

[jdobbs]

What would you think of something like this?

filter1(parm1, parm2)
p:filter2(parm)
p:filter3(parm1, parm2)
i:SeperateFields()
i:FieldOrientedFilter(parm1)
i:weave()
i:filter2(parm, interlaced=true)
i:filter3(parm1, parm2, interlaced=true)
filter4()

By adding the prefix "i:" or "p:" you could force that filter to only be applied to interlaced or progressive sources. But any filters without the prefix (like filter1 and filter 4) are applied to all. That way it could remain compatible with existing scripts.

Well that doesn't sound so bad, but what about if both movie and extras are interlaced or progressive?

On the other hand there are a lot of progressive PAL movies which have a wrong interlaced flag.

I would like to have the possibility to chose to apply filters on a VTS basis or maybe "Apply to all", "apply to movie only", "apply to extras only" basis.

Often you do have a high quality movie and lower quality extras. It would IMHO be nice if you could only filter the extras and leave the feature intact. Or use slight filtering on movie and heavy on extras etc.

Just my 2 cents.

Or use slight filtering on movie and heavy on extras etc.Maybe I could add "e:" and "f:" for "Extra" and "Feature" also...

Yep, but this is more related to the wrong flag on PAL sources.

That's already handled with the "Disable Interlaced" setting -- and that would be honored by the selection of the "p:" filters.
True, but in this case you assume that people know about a wrong set flag, what I doubt. ;)
Maybe I could add "e:" and "f:" for "Extra" and "Feature" also...
That sounds great to me. :)

True, but in this case you assume that people know about a wrong setted flag, what I doubt. If they didn't know... there would be nothing that could be done anyway. DVD-RB relies on the flags in the stream. The interlaced values would be used -- and they would work fine.

This is starting to sound too much like Donald Rumsfeld's "You can take care of knowns, and the known unknowns, But it's the unknown unknowns that you have to worry about."

[jdobbs]

Ok. I've added the "e:, f:, i:, and p:" prefixes. With none of them the filter is applied no matter what. If they exist they work like this:

This filter would apply only to extras:
e:filter(parms)

This filter would apply only to the feature (vts):
f:filter(parms)

This filter would apply only to interlaced material:
i:filter(parms)

This filter would apply only to progressive material:
p:filter(parms)

This filter would apply only to extras that are interlaced:
e:i:filter(parms)

etc...

[Rippraff]

Seems we're talking at cross-purposes today ;)
What I meant it would be easier for beginners to have something like "apply to extras only" so they needn't think about flags or anything.

And let Donald RIP :D

Edit: Your last post :cool: :)

This will be a great new feature! I'm always scanning .AVS prepare files manually in conjunction with RB-Opt to get my filterchains right. Thanks so much for considering the OP's request.

@Rippraff: Do you really think beginners should be messing with filters in the first place? :eek:

[Rippraff]

What they should and what they are doing is a different kettle of fish. ;)

[Insomniak4700]

The flags are a great idea...!

I was thinking something around the lines of radio buttons in the filter window (maybe easier for beginers), but this is a lot more flexible! Besides, most real beginners I know use shrink and not even heard of rebuilder...

When I made the suggestion, I had extras in mind.. can't wait for the next "official" version!
Thanks!

I really don't mean to sway the thread off topic here but I just purchased Superman Returns and I've been wondering what filters can I use to get rid of pixelation that's going on in certain scenes mainly noticeable in underwater. I haven't used filters in ages so please if you can, walk me through it. Thanx. :)

I never even really thought about this feature until I read the changelog. It's a really nice suggestion Insomniak4700. This will definately come in handy in the future.

Thanks jdobbs for implementing it!

[Insomniak4700]

I just tried it today.. just wanted to report it works great!
Thanks jdobbs for implementing it..
