actually, now I've got a snippet of multiple frames from your capture mebejed is what people have as their settings for their base file prior to filters etc.

you've got a richer color base than mine
shadow levels are about the same
brightness and contrast on yours is a little different too.

however, this is all a bit academic since we can correct them to anything we like in Virtualdub or avisynth, but it does show just how widely things vary depending on an individuals perception of the color values and comparing them when they are capturing between source and screen.

been processing with my new script last night. bloody hell sangnom is good. really cured my jaggies and dot crawl issues. okay there are still a few there but a lot less than before and barely noticeable in comparison.

however, when I was trawling through the video I noticed something and I’m really annoyed about it.

when luke has been duffed up by the tusken raiders I have a previously never noticed before shimmer. I thought a filter might have produced it but it’s on my bloody source!! grrrr.

it’s the scene where ben is leaning over luke and puts his hand on his forehead.

the capture is 55 frames. could anyone be so good as to capture those frames from their source in it’s pure uncorrected form and do it as a NTSC 720 x 480 avi in huffyuv yuy2 form codec. and post a link so I can download this correction? from my test it would work out to about an 11 meg file. the actual movie image video needs to be either 720 x 364 high without black bars if anamorphic or 720 x 270 or 272 or 274 without black bars if not, ideally this would be 23.97 fps but if it’s an interlaced 29.97 file (which will be therefore a few more frames and bigger than 11mb)I can IVTC and deinterlace if neccessary. If you captured a number of frames either side of that, this would be cool and I could crop and insert no probs.

if someone could do this pwease pwease pwease then I owe them big style.

alternatively, if not an avi. if someone could screencap the offending frames as deinterlaced progressive bmp’s of the right resolution and provide links for them, then I could assemble the image sequence back into an avi.

I know for whoever is good enough to do this it would mean a bit of time to sort and it would be very much appreciated.

I see the thing about rg24, that's a throwback from an old script when I was passing the script straight into tmpgenc and without it my YUY2 capture source wouldn't display correctly.

the reason I use virtual dub for one and only one sharpening pass is because I have yet to find a avisynth filter that can beat the quality of MSU smart sharpen for virtualdub. it's unfortunate but when I save the avi I save it as a huffyuv yuy2 file. which unfortunately means a conversion but gets it back to a yuy2 file.

if anyone can find a way to make msu smartsharpen work in avisynth then be my guest

the reason Ive used so many HSV and RGB filtering in Vdub is because again, no one filter completely accomplishes what my source needs to be corrected. the problem here is that the filters alter little aspects but all three are needed to accomplish the right look.

would be interested in seeing some of your shots, especially a comparison from source to finished article as this is important to determine just what the filters have done.

sharpening for me is the biggest issue which is why I am still using MSU.

asharp delivers too much edge enhancement when I get the same detail as MSU
warpsharp sucks
msharpen can get as good as MSU but then I lightened lines of resolution top and bottom of the picture.

limited sharpen interests me but I haven't tried it yet, nor can I find much info on it.

Laserschwert did do a lot on it in another thread which I have y et to look at.

well once I'd figured out I had version 2.5.2 avisynth which doesn't support overlay and downloaded 2.5.5 it works. bloody marvellous too.

screenies to come, but sangnom in combination with this script has all but eliminated my jaggies so thanks a bunch laserschwert, without you I was ready to just accept the jaggies as being impossible to eliminate and encoding.

find below my master script

#Star Wars Episode IV : A New Hope Master Script

#Plugins

LoadPlugin("h:\avsfilters\sangnom.dll")

v3 = v1.overlay(v2, opacity = 0.5)

#Add pre-anamorphic borders
v4 = v3.AddBorders(0,45,0,45)

#Add Greedo mos eisley subtitles
v5 = v4.Subtitle("Going somewhere, Solo?", first_frame=70640, last_frame=70680, x=-1, y=334, font="BD Hanover", size=20, text_color=$ffFFff, spc=5).Subtitle("It's too late.", first_frame=70808, last_frame=70847, x=-1, y=334, font="BD Hanover", size=20, text_color=$ffFFff, spc=5)

v10 = v9.Subtitle("You can tell that to Jabba. He may only take your ship.", first_frame=71640, last_frame=71730, x=-1, y=334, font="BD Hanover", size=20, text_color=$ffFFff, spc=5).Subtitle("That's the idea.", first_frame=71787, last_frame=71818, x=-1, y=334, font="BD Hanover", size=20, text_color=$ffFFff, spc=5)

#make it anamorphic
v12 = v11.bicubicresize(720,480).converttorgb24()

return v12

In virtualdub I then adjust levels and color etc but I'm going to add that to this script, so the only thing it will do in virtualdub is MSU sharpen. yes I'm afraid I caved in the end, picvideo @ gentlesharpen is quite nice but I'm afraid MSU still beats it for definition and lack of edge enhancement so I've bitten the bullet and gone for the meagre 4fps it gives me.

to be fair, before it was only giving 2fps so that is at least an improvement and indiciation that Avisynth has at least made a small saving.


my current virtualdub settings are.

vdubs own HSV adjust, hue +0.0, saturation x120.3%, value+0.0%
donald graft's red, green blue adjust, red 97, green 101, blue 100
vdubs own level adjust, input levels 12, 0.978, 255 luma ticked
donald graft's hue saturation intensity, hue 0, saturation 1.09, intensity 1.01

anysuggestions for getting the avisynth equivalents to these into a script so I only have to sharpen in vdub on a seperate pass?

it's just the usual corporate arrogance towards consumers. the thing sells $100 million plus in the opening few days, therefore the fact it isn't of tremendous quality is irrelevant and any admittance that there were issues gets you sent to the funny farm for an extended holiday.

if Lucasfilm were to say, look, this was a release but there is a super duper 6 film all singing all dancing pack coming 2006 I wouldn't care.

LOTR and New Line took that approach so you could make an informed choice.

as it is, Lowry got 1 month to sort the 3 films out, of course things are going to fall by the wayside and the very fact they only got a month indicates it was very much a snap decision by Lucasfilm. I can see the beancounters sitting there thinking, if we don't release the OT in 2004, then we won't get a double header out of it when we re-release it in 2005 with the prequel films as a box set.

the whole thing smacks of oppoturnism with no consideration for the material.

the supplements are good, but we all know there is a lot more material out there that wasn't included and could have been.

considering the amount of time lowry were given, they did quite well, but the quality control must have had one of those days where they look at the footage and say 'yeah, it'll do, who's gonna notice?' and to be honest, if you read web reviews of the DVD sets, that is indeed the case. everyone gushes about picture quality, sharpness of image, but neglects to mention what's been trashed as a result of it.

Better yet, why don't you try setting your dialog norm to 0dbf. Since the audio should have been normalized correctly when they made the ac3 for the DVDs, in theory keeping it the same would result in the same level when you mux it back into ac3.


I don't think that will work. The Doom9 guide says quite clearly that if you don't normalised it close to -29 to -31db ish, it can result in DRC occuring in the wrong place which can result in incorrect pumping and clipping of the track.

what pisses me off is that we are dealing with an already normalised track. they should put in a bloody option for it to be encoded as is, ie just convert it to AC3 without pissing about re-normalising and DRC'ing the wav's.

so as I understand you Zion, schwerts script takes two versions of the capture and is overlaying them so you have half the fields from one, and half the fields from the other, then around V5 line combining the two back together into a single 23.97fps ivtc source which is anti aliased, color corrected and sharpened up?

so in my case, as I have a IVTC source file with jaggies, all I need to do is run sangnom as a normal filter

avisource=("p:\anh\interim\anh_interim.avi")
sangnom(order=x,aa=x)

rather than structuring it as schwert has done

could you explain a little more about using this sangnom filter in avisynth.

I use stuff like dust, decomb, msharpen etc but those are all single line command filters. I don't understand anything you posted about this

my ANH is prone to a number of jaggies from the decomb IVTC process using Donald Grafts filter. this sangnom filter seems quite nice and there is a similar thread over at Doom9 but both yourself and this thread do this

LoadPlugin("E:\Programme\AviSynth2\plugins\bak\MaskTools.dll")

v1=AviSource("e:\zion_rec.avi").SeparateFields.SelectEvery(10,0,1,2,3,4,5,6,9).Weave.AssumeFPS(23.976)
v2=AviSource("e:\zion_rec.avi").SeparateFields.SelectEvery(10,0,1,2,3,4,5,6,9).Weave.AssumeFPS(23.976).crop(4,0,0,0).AddBorders(0,0,4,0, color=$FFFFFF).blur(.5)

v3 = overlay(v1,v2, opacity=0.2, mode="Darken")

v4 = v3.Crop(0,102,-0,-102).Lanczos4Resize(720,600)

v4a=v4.SangNom(order=0)
v4b=v4.SangNom(order=1)

v5 = v4a.ConvertToYV12.overlay(v4b, opacity=0.5).LimitedSharpen
v6 = v5.Levels(0,1.236,224,0,255).Lanczos4Resize(720,376).AddBorders(0,52,0,52)

Return v6

and I don't understand this vbusiness at all what's the point of v3,v4,v5 etc if you stack all the commands in a certain order anyway, am I supposd to paste this into the avs file?

also, I've already got an IVTC's interim so all I need to do is anti alias using the sangnom filter.

am I better doing this?

LoadPlugin("p:\avsfilters\sangnom.dll")
avisource=("p:\anh\interim\anh_interim.avi")
sangnom(order=x,aa=x)

x being 0,1 or 2 for order and aa=x being the amount of antialiasing you wish to do.

I assume as my source is progressive that I need to use order=2 or do I run sangnom just as sangnom(aa=x)

and would I need to convert to yv12 for thisfilter to work? in which case I'd need avisynth 2.7

I noticed something last night and that is that without access to the original film, ALL the sources we're going to use, apart from the lowry raped SE DVD have overblown highlights. that much is evident by using the Princess Leia v Vader corridor conversation in the white corridored Tantive.

the top of the Stormtrooper helmets get lost amongst the ceiling light. The only version of star wars I have seen that does not have this issue is the new 2004 DVD.

to be fair, it's not blown by much, but it is enough to make us see a noticeable difference. I had to laugh when someone pointed out that my projects screencaps. that corridor shot, one of the ribs in the door frame is nearly invisible, then I looked at my original capture which is untouched and it's virtually not there either so it's a source issue rather than my efforts.

makes me more and more convinced that the way to go is to DE-SE the DVD using footage and color correction etc, basically what Mverta is doing.

oh well I'll try that then,

I think what I will do to test it is.

mux the wavs into a new ac3, then demux that back to a new set of six wav's. I know it will degrade a bit but it will allow me to see how much the audio has dropped between the pre and post wavs.

then I can boost the pre wavs in appropriate fashion to allow for the volume drop.

see, now I get that part of the explanation but it doesn't make sense when I explain what I'm using to test.

I demuxed the attack of the clones AC3 file from its VOB as it and TPM are the only 5.1EX DVD's I got. The demuxed wav has a good rich volume to it.

after I've then used either ac3machine or 5.1 soft encode to effectively mux it back into 5.1 AC3, the sound level has dropped dramatically which is a bit odd considering the source AC3 has so much more volume.

settings in soft encode were

512kbps AC3 DRC @ film:standard RMS value for dialogue normalisation -9db

before anyone suggests premier, I must admit to not liking it for this sort of thing, big file encoding because it gets a bit unstable in my experience with big files.

so saying that, personal preference have anyone ever used Cinema Craft Encoder and TMPGenc or just CCE? I've only ever used TMPGenc and hear lots of people says CCE is better.

any opinion on this?

better picture?
quicker to encode?
easier to use?
harder to use?

opinions welcome

as much as I like the sound of Vegas I don't have $600 to spare.

so with what I got I have one remaining issue.

besweet split my test 5.1 EX Ac3 file into six waves which are about 800mb each and of good volume.

when I then run it through 5.1 soft encode it's bloody quiet.

now, I scanned the center channel in soundforge as per Doom9's suggestion and it's average RMS value was -22db.

now my read of the doom 9 thread means that I apply -9 to make it -31 altogether or have I read it wrong?

*edit * since writing this I've re read this with a fresh head and it would appear that the value you use is the value of the average.

so I should have set -22 in soft encode? the more I read I think this is what I've done wrong. no wonder it's so quiet.

the only other thing seems to be that soft encode is bloody buggy. would I be better off encoding in Scenarists own AC3 encoder?

@ Mebejedi,

bit of a problem with this ac3 to six waves conversion in besweet. it's coming up with downflow overmix which I assume is some kind of clipping.

I have the following set in besweet

input is an Ac3 file, output is selected as six waves. compress dynamic range is ticked, ssrc downconvert sample rate is ticked and showing 44100 which seems wrong to me.

have I set this thing right?
