Well, VHS capturing Mostly cartoons, having some questions:)

[jagabo]

Plus a little deshaking with Stab(default settings).

[zerowalker]

Yeah, that is the Results i want, except for the low bitrate blocky things:P
But can´t you reach it without the use of Neat Video?

[themaster1]

Why did you capture the video with this size (768x410) can't understand really now it's a mess to work on it can't you just stay at 720x576 ?

Result:

(1st: fft3d, 2nd: neat, 3rd: original, 4th: deshake (jagabo)

[zerowalker]

Okay, i used a crop one, forgot i had cropped it...
Here is Another part i had though.
But i looked at yours, and and i don´t really like the Neat Video, cause of the blocky lines it causes.
The fft3d is nicer, but i wonder if you can prevent the "aura" around object or what to say, it´s like heat is coming from the girl. by maybe it´s like that from without filter, not sure.

[jagabo]

Yeah, that is the Results i want, except for the low bitrate blocky things:P

That's just because of the Xvid comrpession.

But can´t you reach it without the use of Neat Video?

I don't know now to do the equivalent in AviSynth without Neat Video.

FWIW, here are mine using free filters only. If you like it I can post the script

[zerowalker]

Can i get the Scripts and such from Both of you please, so i can try a bit myself in different parts in the movie?
Thanks as always

EDIT: Also interested in the encoding settings, as i use x264 with megui.

[poisondeathray]

I think I messed up the colors in my 1st attempt, I find it difficult to color correct in avisynth (I would normally use another program, or even vdub curves or colormill; the reason is you can do non linear adjustments a lot easier) . I went by assuming the sky was supposed to be blue instead of the reddish hue, and the apron part of the dress was supposed to be white. I attached one with better colors

I think I used weaker denoise settings than themaster1, but you can always the settings or strength of filters adjust to your tastes. I didn't stablize it either, but you can use stab() like jagabo suggested, or deshaker in vdub, or depan


Some notes:

Your video has duplicate frames. This is common in anime. The real fps is 12.5, and every 2nd frame is exactly a duplicate. It's important when using temporal filters to decimate the duplicates beforehand, because they examine for differences between frames. This has added benefit of processing a lot faster because fewer frames to process. e.g. You can use selecteven() or selectodd() .

You can encode with the double pulldown flag using x264 - this would be slightly more efficient (1/2 the frames to encode, but it's not a linear gain), but many media players and devices don't support this. So a "safe" way would be to re-double the frames after processing filters e.g. interleave(video, video) , or another option would be to encode the video as 12.5fps with unique frames.


Besides the reddish hue, and obvious noise, the other artifacts worth mentioning:

1) Aliasing - looks like jaggy stair stepping edges. You can use antialiasing filters, there are dozens to choose from in avisynth. I used santiag in this example

2) Chroma Bleeding - the color doesn't fit inside the lines, it's almost as some pre-schooler screwed up coloring with the crayons. I think you were referred to this as the "aura" . You can use MergeChroma(Awarpsharp) for this

I broke it out into stages with lossless intermediate in between each, but you can do whatever you feel like. As ususal , adjust to your own tastes. Some prefer super clean anime, some prefer lots of detail remaining and don't mind a bit of noise . I think you will get better color results using non linear adjustments (e.g. curves)

#1st stage
AVISource()
SelectEven() # or selectodd()
MCTemporalDenoise(settings="very high")
 
#2nd stage
AVISource()
Crop(0,4,0,-8,true)
Dehalo_Alpha(rx=2,ry=2,darkstr=1.1,brightstr=1.1)
Santiag()
AwarpSharp2(depth=6)
Toon(strength=0.5)
LSFMod(strength=50)
TTempSmooth(maxr=5, lthresh=12, cthresh=4, strength=5)
SmoothLevels(25,1.2,255,0,255)
SmoothTweak(contrast=1.1, hue1=18, hue2=-23, saturation=1.2)
MergeChroma(awarpsharp2(depth=48))
Deen()
DFTTest(sigma=32,sigma2=32, lsb=true)
msb = last.Dither_get_msb ()
lsb = last.Dither_get_lsb ()
DitherPost (msb, lsb, stacked=false)
GradFun3()
AddBorders(0,4,0,8)
 
#lossess intermediate for input into encoder

This will return 12.5fps, with unique frames. If you want to encode at 12.5 fps, go ahead, or duplicate the frames

eg.
a=AVISource("video.avi")
Interleave(a,a)


For encoding settings, it depends on what your intended playback target is. Devices have some restrictions. You can start with the presets, or even use an animation tuning preset. But without more infomation, I cannot provide any specific suggestions

[themaster1]

Here is mine with the x264 settings (need staxrip): http://www.sendspace.com/file/7tku5j

edit:
for pal you'd have to pick bt470bg for colorprim,colormatrix,transfer and videoformat: Pal
for non interlaced source remove "pic struct" (misc) and --tff option (command line)

[zerowalker]

My playback will probably be only on PC. I am using Megui with x264 and different Audio, prefer Ogg and Flac, (if you can tell me anything better than Ogg as lossy please tell me).

I looked through your settings with Staxrip Master and i can use most of it in Megui i think, but don´t really know what bt470bg does, is it for devices or does it do any difference?

And thanks for the script Poison, don´t really get how to do the 12.5 to 25 or vice versa, but i will try and find out.
and how do you set up 2 passes, i am currently doing the first pass, then going to do other on that file.

[themaster1]

1="bt709", 2="undef", 4="bt470m", 5="bt470bg", 6="smpte170m", 7="smpte240m", 8="film"

bt470bg that's the color matrix you should use for Pal imo but i think most decoders prefer bt709 so you'd have do make a matrix convertion if you want bt 709 in such case: colorprim = bt470bg; colormatrix= bt709; transfer = bt709


For two pass i pick "mode:2pass" and that's it (see 1st picture)

[zerowalker]

Okay will try out with the color matrix stuff
But with 2pass i meant the Avi Synth from poison:P
Thanks as always ofc!

[poisondeathray]

I used 1 pass CRF. 2pass rate control is only useful if you need a fixed filesize or bitrate (e.g. you need to fit a specific filesize onto a BD, because there is limited capacity). If you don' t need a specific filesize, then use CRF, it gives you constant average quality

For the frame rate, if you use SelectEven(), this means every 2nd frame is chosen, so frames 0,2,4,6,8,.... This means 1/2 the number of frames , but half the FPS as well. This is the actual rate anyways in your animation

If you wanted to double the frames (duplicate every 2nd frame), use the instructions above with interleave. Interleave(a,b) would mean : frame 0 video a, followed by frame 0 video b, frame 1 video a, frame 0 video b. It alternates the videos. But since you're only using 1 video with Interleave (a,a) , this means you're just doubling the frames

[zerowalker]

Okay, think i got most of it
Where can i get Santiag btw?
Can´t seem to find it.

[Brad]

I doubt the whole movie is 12fps. Usually most of the animation will be on twos but things like pans will be full rate.

[poisondeathray]

Okay, think i got most of it

Can´t seem to find it.

just search google you can find most filters. use words like "avisynth", "doom9" + the filter name. It was the 2nd hit for me. The original function is post#12, but there are several modified functions in that thread. That thread has a list of a number of AA functions you might want to try

http://forum.doom9.org/showthread.php?t=153835

I doubt the whole movie is 12fps. Usually most of the animation will be on twos but things like pans will be full rate.

This is a good point, zerowalker should check the other sections.

[zerowalker]

Okay, think i got Santiag fixed, will have to wait for the temporal noise run to test it out
And yeah, it seems 12 fps was fail as it looked like everything was lagging:P
But will play around and post results

[zerowalker]

Hmm, okay i can´t get Santiag to work, i don´t know what to do with the text, i tried copying it to an Avs and importing it.
Can i please get some help?
Thanks as always!

[poisondeathray]

exactly what error message do you get ?

copy & paste the function to the bottom of your script , or copy & paste it to a text file, put it into the plugins directory, and rename the extension from santiag.txt to santiag.avsi (avsi are autoloading).

NNEDI3 is a prerequisite for santiag

did you check other parts of the video to see if its same pattern ? duplicate frames

[zerowalker]

I don´t know about the duplicate frames, it´s probably when they are talking and standing still etc, but when the "camera" is moving it´s lagging atleast:P

I had failed on Avsi, just named it Avs.
Now i just need NNEDI3, thanks for helping

[poisondeathray]

its very important to check, otherwise it won't work properly. You will need a different script, or process it in sections. You don't want to throw away good frames

just open the source original video without filters and go frame by frame with the arrow key in vdub. Is every 2nd frame the same or different ? Check different sections

[zerowalker]

Okay well, i tried what you said, and it seems the characters have duplicated frames, but fading in and out, and moving is 25 fps.
But what is wrong with the script then?
I did the first one without select even thing.
Now i am gonna do the second one, on that one.

[poisondeathray]

You lost me. I don't know what you're doing. Just check the original for duplicates

Or you can process it in sections that have duplicates

Or erase the SelectEven() line and process it at 25fps with the duplicates (temporal filters won't work as well), but it might be easier for you

Just adjust the parameters to however you like it, if it looks ok use it.

Cheers

[zerowalker]

I removed SelectEven(), as it there was 25 Fps, at some places;D

[zerowalker]

Okay, while testing it out on Alice which will take about 8 hours, i would like to ask a thing
I have been using Ogg as it seems to be the best compression codec exception for FLAC of course.
But can anyone tell me which you prefer and why?
Cause when i am going to Archive the rips some will be FLAC while others will be lossy, depending on how much i liked the movie etc.
So is Ogg the best or similar, and what Quality is recommended, or bitrate for other audio codec etc.
Anything goes, just tell me!

EDIT: as i am using Megui, i got this setting called, Preferred Decoder, i can there choose between NicAudio, FFAudioSource and DirectShow. Is this important?

[jagabo]

I would use AC3 or AAC for future compatibility.

[zerowalker]

Future compatibility?
Is that really of concern for pc playback, or maybe you thought of devices?
I am not good with Devices compatibility, so please tell, knowledge is power

[jagabo]

I'm thinking of other devices. Someday you'll have a TV or some other device that can't play your files and you'll wish you had used a more widespread format.

[zerowalker]

Well mostly use the PC for everything, but compatibility is an important subject indeed, will probably make 2 versions for what i am unsure of then, ogg and aac, but i can see there is Nero aac, and Faac, which is gives best result?
