............................................^^ the line in question


You can clearly see a line from top to bottom on EACH capture i release from a vhs ntsc

Actually it's not entirely green looks like it is green/yellow & a bit of Red too but the most noticable color to me is Green.

I have no idea how to get rid of this ugly thing

i got a brand new capture card,terratec, chipset philips
i used Dscaler,Chris Tv(with ffdshow) etc.. i couldn't get rid of of this

My card,works very well(tested with satellite and pal/secam vhs) but as you can see i have some issues with those ntsc vhs

ps:no no no i will not buy a TBC(no money for that)

I tried this filter called fft3dfilter with avisynth 5 minutes ago,i didn't see any results frankly

Im looking for a filter working with virtualdub or avisynth to isolate this green portion and somehow shift this up or down i don't know...something to isolate and reduce this artifact.....you see

Thanks for your help folks

Hello somebody alive in here?

[SallyDog]

It's always going to be there. You need to crop it out.

[Mounir]

croppin it out?

have u lost ur mind

did u see the picture above & the place where is the line lol

[SallyDog]

Oops, now I see it. I was only looking at the bottom of the picture. What the hell, crop it anyway :D

@Mounir

Hi!My card,works very well(tested with satellite and pal/secam vhs) but as you can see i have some issues with those ntsc vhs1) If you PLAY the NTSC tape, does it display the same problematic artifacting?

2) Are you using the SAME player to play the NTSC tape(s) and the PAL/SECAM tapes?

If not, perhaps the problem lies with the heads of the player...

[neuron2]

I don't see any line.

@Mounir

Hi!1) If you PLAY the NTSC tape, does it display the same problematic artifacting?

The snapshot comes from a NTSC VHS RIP
i got like 10 vhs tapes,each time the same problem,my VCR IS BRAND NEW,SAME FOR MY CARD.

NO PROBLEMS WITH PAL/SECAM(= NO LINE)


2) Are you using the SAME player to play the NTSC tape(s) and the PAL/SECAM tapes?


Of course i do,what you want me to use....think i'm one of these rich guys who have ten vcrs at the house?
my VCR is a Daewoo 6 heads PAL/SECAM/NTSC PLAYBACK

[setarip_old]

The snapshot comes from a NTSC VHS RIPI asked you if you play the tape and watch it on your TV, does it exhibit the same artifacting as your capture/"rip" - or does the artifacting ONLY show up on your capture to your computer?Of course i do,what you want me to use....think i'm one of these rich guys who have ten vcrs at the house?
my VCR is a Daewoo 6 heads PAL/SECAM/NTSC PLAYBACKAnd would you expect me to have known that? I don't have a crystal ball ;>} I'm just trying to help you narrow down the possible causes for your problem...

[Mounir]

I asked you if you play the tape and watch it on your TV, does it exhibit the same artifacting as your capture/"rip"

YES(100% affirmative)

*my EAGLE EYES(I DO NOT WEAR GLASSES) have detected this "green,yellow,red" line.

[setarip_old]

You can clearly see a line from top to bottom on EACH capture i release from a vhs ntscNow that you've made it clear that the NTSC TAPES exhibit this artifacting, I'd suggest you try to play them on a different player (Perhaps in an electronics store), to determine whether the poblem lies with the tapes or the way your player plays NTSC tapes...

[neuron2]

I still don't see a line. Is this some kind of joke?

[squid_80]

It's not a single line, it's a rectangle section with an odd "tinge" or color shading (yellow/greenish). On my LCD it stands out most on the chair/couch, while on my CRT the couch is too dark and it's only really evident below the toe of the shoe. But it's there alright, he's not making it up.

[neuron2]

Just goes to show how important precise language is.

[jggimi]

It looks like its the same color as the pattern on the wall of the stairwell in the background. My first thought is blended fields, as I do not know if the output is actually NTSC or if the VCR is doing a poor job of NTSC->PAL conversion. But my second thought is not blended fields, as the location of the "stripe" isn't close to the background.

How is your VHS connected to your capture card? Composite or Svideo? What model VHS is this Daewoo? What model Terratec card? From the looks of it I'd say your player (albeit new) has issues perhaps with one of the read heads. If this is new and if possible, you might see if you can return/swap it for another of the same model. I've seen this problem a couple times with cheaper/lower-end VHS players and either faulty, scratched, or dirty read head(s).

I got a LCD too & to me it's really evident,i can clearly see this line

i have burnt a few of my rips on dvd & watched on a regular tv,
i can clearly see the line still.
absolutely disgusting

composite sir ..composite think im a noob?

s-video would result to a white & black picture only ....of course

well the truth here is that i bought this vcr real cheap..that doesn't mean it the vcr's fault


my card is a "terratec cinergy 250 pci"

[setarip_old]

You now have three members, including me, who are suggesting to you that your VCR, or the NTSC tapes, may be the cause of your problematic playback.

I would once again suggest that you try to play them on a different player (Perhaps in an electronics store), to determine whether the poblem lies with the tapes or the way your player plays NTSC tapes...

BTW - You have started this thread because you are seeking assistance. The "wiseguy" responses you've given to both me and "chipzoller" are not appreciated.

[Mounir]

did i mention that those tapes are commercial?

Is there any possibility that..in some way or another there is some kind of "macrovision" signal residue in the picture?

If u ask me, the picture is perfect except this green color surface/ or line whatever you wanna call it

I didn't see any macrovision artifact(on a tape) in my life so i don't know how it looks really but from what i know macrovision provides some similar green artifact...but of course in all the picture(s)

edit: well actually i have non commercial tapes and it's the same thing so i don't think it's a macrovision issue

[setarip_old]

Macrovision (depending on which version is used) will periodically generate a gradual brightening and dimming of the entire screen image or a thick white horizontal band across the center of the screen...

Check out the tapes on another player...

[chipzoller]

Do you have any intention of answering the questions I posed to you in my last post?

[Mounir]

I am using the composite wire as i said previously

my vcr model : daewoo SV-300W (6 heads,pal/secam/ntsc)

I also indicate to you that i periodically clean te heads with a special tape(every 10 reads more or less)

EDIT:
Somebody told me that my problem is recurent because most of CAPTURES CARDS sold around the globe can only decode correctly a signal coming from a vcr delivered at 3,58 Mhz for the Ntsc color system.Unfortunately,the European VCRs suposed to have capabilities to read ntsc(like mine) delivers a 4,43 Mhz frequency(only) :/

Well i don't know if this is true but this guy know a lot for sure

[setarip_old]

Somebody told me that my problem is recurent because most of CAPTURES CARDS sold around the globe can only decode correctly a signal coming from a vcr delivered at 3,58 Mhz for the Ntsc color systemWhat could a capture card possibly have to do with how your tape plays on your VCR and appears on your TV?

[Mounir]

Actually this is not a frequency problem according to him because the colors seems good on my caps.

It's probably a "horizontal blanking problem for the chroma" as he said because he told me he had similar issues with 2/3 tapes before( like me) so he went back to the store to get this fixed but i guess he paid some extra buck for that.

I have no idea how to fix this up myself w/o passing through a specialist unless someone know what i'm talking about and know an easy procedure :/

Setting repair/correction of your current equipment aside for the moment -

Did you TRY another vcr?

Did you TRY the second fft3d script that soopafresh posted for you over at videohelp? (http://forum.videohelp.com/viewtopic.php?t=315267&sid=1cb2cf5b3ae94084b444a1490301356c)
His before and after screenshots looked like a fair amount of improvement to me.

mergechroma(last)
fft3dfilter(bt=4,sigma=19,plane=3,degrid=1)
fft3dfilter(bt=4,sigma=19,plane=2,degrid=1)
fft3dfilter(bt=4,sigma=19,plane=1,degrid=1)
mergeluma(last)

Maybe this would improve your existing captures enough to make them acceptable to your eyes.

[Mounir]

i tried another DAEWOO TV/VCR combo & and surprisingly i didn't a see the line in question.

[grannyGeek]

Well, there you go.
Defective vcr !!!

Glad it worked out for you.

yes i tried,the results(2.65mb each):

after :http://www.mediafire.com/?8nyqzmjkzq1

conclusion:no effect AT ALL according to my eagle eyes for the green line and even WORSE for the general look of the pic:

result with the filter "fft3dfilter"+"merge chroma":

[Mounir]

Glad it worked out for you.

You wouldn't be so "glad" if you were me because I'm still rolling with my regular vcr man...

...so the problem is not solved still.


Furthermore the so-called filter " fft3dfilter" is a <<deleted>> obviously lol

1) Go and get your VCR repaired, or replaced. You have a problem with it.

2) Read Rule #4. People are trying to help you, and you are being abusive.

That was more an observation than a reproach but thank you for your advice.
