i'll check that
it's another part of the same capture ..
it was a follow up on my ColorYUV(Levels="PC->TV") question
i tried ConvertToYV12(matrix="PC.601") and gave me an error

those presets saves me time , i think
i'm still a newbie in all of that
if i had a better idea how to translate into numbers ; i'd do it
maybe have you got some reading to suggest to me ?
i could try some commands in the ColorYUV wiki page
off_y moves the whole graph up
gain_y stretches the graph from the bottom
cont_y stretches the graph from the middle
gamma_y is a non-linear stretch from the bottom (brings out shadow detail)
Negative values move the graph down or compress the range.

I agree with very little in this thread so far.
MPEG-2 I-frame @ 20Mbit is fine.
I would not lighten/crush the levels at all. ATI is quite accurate. Sources may be off, however. Adjust for source only.
A better VCR should be used. The 5800 is rather low-end, lacks TBC. You need an internal JVC TBC, based on images shown.
TMPGEnc is a noisy encoder. It works, but you need to use higher-than-normal bitrates.
I've covered all of this before, both at this site, and at http://www.digitalFAQ.com/forum/dvd-video
Find my posts here, any Site Staff post there, and get to reading.
this must be one of my worst tape
and my 5800 is fine , i'm not aiming for perfection , vcrs are hard to find now
and i will use avstodvd (HCenc) for encoding
and i will try your suggestions , thanks to all for your patience
and for MCTemporalDenoise() my cpu is an athlon xp only supports sse and not sse2 nor sse3 so i think i can't use it

should i separate fields when using TTempSmooth ??
TTempSmooth() has an interlace flag. TTempSmooth(interlaced=true).
with this :
ColorYUV(cont_y=-15, cont_u=-80, cont_v=-80)
Avstodvd produced this:
Video = Import("F:\100 limites\Nouveau dossier\Source..avi.avs")
Video = Video.ConvertToYV12
Video = Video.ConvertFPS("ntsc_video")
Video = Video.ColorMatrix(source=0,dest=2,interlaced=true)
Video = Video.hqdn3d(10)
Video = Video.AddBorders(4,0,4,0)
Video = Video.Lanczos4Resize(720,480)
i think it's an improvement ..maybe not perfect
some things may be improved
i did the whole capture again but with virtualdub and no sync issues
gave me a slightly different file (712X480)
oups my uploads didn't work ...

still didn't work ,, (my uploads) i give up
30 MB limit here.
i had 2 files one around 20MB and the other close to 27 i'll trim the bigger one
here it is
That looks fairly good given the quality of your source.
I don't know why you would need ColorMatrix(source=0,dest=2,interlaced=true) but the colros do look a little better.
I don't know any way to get rid of those hum bars (the waves that move slowly down the frame) after capturing. Are they on the original tape or only after capturing?
that was a 709>601 matrix type of color convertion thing
didn't seam to hurt much ,
my blacks and whites were a little more than borderline

electrical interference maybe !?
was even maybe taped onto a previously recorded tapes
and not the highest grade one
errors tend to had up.. dirty heads may be in the chain too
i had some tapes , when i was young living in appartment, recorded with rabbit-ears
not the strongest signal
i guess it is on the tape
i would really like to know how to prevent those kind of errors
it's been a long time since i hooked up a vcr to a tv set
my pc and system is a temporarely setup
i've got a room being made this summer where all my gear will be
(musical , home theater and pc)
very good themaster1 ; specially for the bottom part that was more distorted
How did you do that ? how did you get all the chroma noise out ?
my cpu (old athlon xp.. not that fast ) can't take some instructions (sse2 , sse3 .. i don't really know)
i just try and try this and that ;and see what i can do , and trying (i said trying) to understand what i do
i'm no pro

I think you can still use any filter, the SSE2, SSE3 intructions sets just help speed up calculations. Most avisynth filters will fall back on the other instruction sets like MMX. It just will be a bit slower for you
I suspect those undulating bars are remenants of the chroma noise not being completely removed. But your "source2.avi" and "output.m2v" aren't the same clips, so it's hard to say for sure. As for the underlying cause, not idea.
Here is my go at it
would be fun if you shared your scripts ..
in fact source2 is the very end of output.m2v i just edited it so i could post it here
if i get good results doesn't bother me to wait a day or 2
it's a 46 min capture
Last edited by smartel; 18th Jun 2011 at 00:08.
Yep, no problem .
I realize source2's and output.m2v's relationship, but if you look at your output.m2v, the undulating noise is not as noticable where the clips overlap. It's more noticable at the beginning, where there is no overlap - so it's hard so draw conclusions. Was there a different pattern going on?
Actually I can replicate the undulating pattern if I remove the removedirtmc section of the script below, I thought was the edge of the chroma noise bars, but it's probably an underlying luminance frequency issue
Because it moves field to field when you group even/odd fields, you can catch it with removedirtmc if you apply strong enough settings. If it didn't move that fast, you wouldn't be able to detect it with that filter
Another approach might be to use FanFilter
AviSource() ConvertToYV12(interlaced=true) Checkmate() Chubbyrain2() FFT3DFilter(sigma=6, bt=3, plane=3, interlaced=true) SmoothLevels(0,1,255,15,245,chroma=200) SmoothTweak(saturation=0.85) AssumeTFF() SeparateFields() f1=SelectEven().RemoveDirtMC(50,false).TTempSmooth(maxr=4, lthresh=24, cthresh=4, strength=4).LSFMod(strength=50) f2=SelectOdd().RemoveDirtMC(50,false).TTempSmooth(maxr=4, lthresh=24, cthresh=4, strength=4).LSFMod(strength=50) Interleave(f1,f2) Weave() Spline36Resize(720,480)
different pattern .. i just applied the scripts in post #42
i'll try your script
I may not have all the plugins to do it right now i'll search them
it's getting a little technical , english isn't even my 1st language
but one step at the time , slowly getting there
hoping it'll work for the whole capture (and similar one)
well i've got homework to do , thx a lot for your help . it's really usefull
all of this will surely help me in the futur to deal with future captures
Chubbyrain2() did a good job at removing the hum bars.
I had the op's filter chain with, CheckMate() and hqdn3d(10) sitting on my desktop (still had hum bars), and added Chubbyrain2() after Checkmate(). But yes, ChubbyRain2() alone doesn't remove the hum bars.
i've never worked with auto loading script ..
FFT3DFilter cannot load FFT3DFilter.dll error # OK solved !
for smoothlevel what dll should i call in my script ??
smoothajust SMVC or ICC ? Both ??
i guess it's x86 notx64 (xp pro 32 bits) #OK Solved
should i call every dll individually ?? that's what i try to do now..to avoid each error that avisynth gives me ..
i think i've got a little difficulty to setup this chain
maybe these individual fonctions are part of bigger more pratical combo filters ?
maybe i should post my entire script ?
