AVSynth filtering and other questions

[JesseD]

I've looked around and have truly no idea how to filter out the grain in a picture. In time I'm looking to start making AMVs but I want to get the hang of doing things like filtering and the like first.

Vegetto EX! You have set me on the road to making AMVs and told me to read through the AMV.org guides. I truly am floored at how helpful the guide was on the site. I discovered AVSynth and DGIndex and it has certainly changed my veiw on things and put me up a step to making AMVs.

I remember that you said you filtered out some of the grain in Honey and Clover. I've made a .dv2 file of my Ultimate Uncut Movie 1 and an .avs to match it. The movie is in 4:3 and has a nice amount of grain, but I would like to filter this out fully. Simply to see what it looks like and to get used to it etc. These are probably dull questions, but the only dumb question is an un-asked one, right?

How would I crop the Widescreen DBZ DVDs? They're crap(and I don't even have them yet) but they are uncut and I m willing to sacrafice 5% of the picture either side to make it a 4:3 picture so it will blend with my other FUNimation stuff.

I am new at this but I am learning everyday. I'm on the same wavelenghth as other people now so I don't feel like so much of an idiot.

Am I right in reading that your main question is simply how to crop & resize a video file via an AVS script?

mpeg2source("C:\location\file.d2v")
Crop(0,0,0,0)

In order, the numbers go Left, Top, Right, Bottom. For the right and bottom, you have to enter negative numbers, though. For example, if you wanted to crop eight pixels from the sides and two from the top, it would read (8,2,-8,-2).

And then when you want to resize it back to a proper DVD aspect ratio:

mpeg2source("C:\location\file.d2v")
Crop(8,2,-8,-2)
LanczosResize(720,480)

For those wacky "remastered" episodes, if you really wanted to get them to a 4:3 aspect ratio, you would have to crop exclusively off the sides, and then resize it back up. I guess it would be something like:

mpeg2source("C:\location\file.d2v")
LanczosResize(640,360)
Crop(80,0,-80,0)
LanczosResize(640,480)

I would suggest cropping the 60 pixels each from the top and bottom of your "Ultimate Uncut" movie 1 to fit with the rest of the stuff (take it to the 720x360), rather than going the other way.

I probably got some numbers slightly off here and there, but you get the point .

Yes that answered my question. But my other question was: how do you filter out the mpeg2 grain? Ye old Dragon Ball has a lot of grain and so forth and so come. So how do you get rid of all of that? This might sound stupid. As for colors the FUNi colors ain't all bad so I'd leave 'em. You can't really remove scratches on the film but it adds charcter.

So you would reccomend cropping 4:3 picture, huh? I did think of that but Dragon Ball was meant to be in 4:3. So I'd be missing out either way.

Whoever thought of making DBZ Widescreen, needs to have thier penis(assuming they're a male) chopped off and then stewed into Brolys morning Cornflakes.

That's fucking disgusting. As for filtering out the grain, well I just don't. To me grain is kind of appealing. In my opinion it adds character to what I'm watching. To each his own.

Sorry I just went a little... erm... crazy? The widescreen isn't that bad. Just nothing to shout about. Dragon Ball has grain lets face it. It adds it's own charm. I just want to filter out enough so that it looks clean, and not completely filter it out. Jut enough so that you can't really see it. I understand where you coming from, though.

Please! Does anyone have any idea how? If not I COULD just leave it, BUT I want all my DVDs to look consistenetly clean. Vegetto EX, you seem to know how. Just tell me.

I'm sure VegettoEX would love to help, but maybe he's just too busy to respond at the moment. Those DVD's aren't going anywhere, so just lay back and browse through some of the other topics and eventually you'll get a response.

Searching through Doom9 I came across Vaguedenoiser. I haven't had a chance to try it myself, but read over some of the guides at Doom9.org and maybe you'll find it useful. Don't be afraid to search for what you're looking for. Google is your friend.
