    I'm afraid the pictures don't "tell all". If you want us to know "all", you have to give more information. don't just wait for someone to guess what you're doing.

  3. I have the ghosting effect or shadow effect, when i play my vhs to an other player.
    Only in the vhs player, which the cassett was recorded, is no problem.
    BUT i want to play it on other players, or better in a svhs because the picture in my vhs player is to much soft.
    With an svhs you have a better shrapness.
    I try other cables, other outputs (cinhc,-svideo...) No luck.
    So I wanna capture it with an svhs with" shadows" and try with some plugins to solve the problem with the shadows.

    What is the source of the video you are capturing? What are you using for capture? How were the images made? If the images are from PAL video, why is the frame size 766x576? Have they been resized from the original video?

    The SVHS player is sharpening too much. If the player has a sharpness control, turn it off. If you are sharpening during capture, don't sharpen.

    plugin to reduce halos: DeHalo_Alpha or DeHalo_ALpha_mt (http://avisynth.nl/index.php/DeHalo_alpha)

    plugin to reduce halo and luma/chroma smearing: aWarpSharp (http://avisynth.nl/index.php/AWarpSharp) or aWarpSharp2 (http://forum.doom9.org/showthread.php?t=147285). Examples of usage (use either of the examples below):
    --- MergeChroma(awarpsharp(depth=30))
    --- MergeChroma(awarpsharp2(depth=30))

    A plugin .avs to clean similar edge artifacts (DCT ringing): HQdering (http://www.animemusicvideos.org/forum/viewtopic.php?f=44&t=98079).

    anti-ghost plugin: ghostbuster (http://forum.doom9.org/attachment.php?attachmentid=12721&d=1330678606). Howeverm, the VirtualDub version of a similar filter (exorcist.vdf) is easier to use (http://www.softpedia.com/dyn-postdownload.php?p=113614&t=4&i=1). Unfortunately the best and easiest anti-ghost filter I've used comes with the TMPGenc Plus 2.5 MPEG Encoder. But none of the ghost filters are perfect.

  5. Turn off the sharpening filter in the SVHS deck. It is creating those oversharpening halos. You can reduce them in software with de-halo filters but it's best not to get them in the first place. The VHS cap in your first image is a far better starting point for further filtering.

    Agreed. I forgot to mention that the top VHS image looks more workable. If you remove halos and edge ringing fom the sVHS version, the characters look almost alike in both images.

  7. hi
    the shadows are not permanently.
    they are often behind texts.
    here a example, you see only on different places there are shadows, not in the whole picture.
    http://www5.zippyshare.com/v/46803479/file.html ( click on download)

    and here the same tape with no shadows from the vhs player which was recorded but very unsharp ( Orion VH-2905 )

  8. The SVHS cap does have a lot more detail than the VHS cap. Does the SVHS deck have a sharpness control you can adjust? Try turning it down a little bit. Try:

    Dehalo_alpha(ry=0.01, rx=3.0)

    to remove the halos.

    Stay with the VHS player. Your SVHS machine has too many problems.

    Unfortunately the avi links are not the original source. They are poorly deinterlaced (why are they deinterlaced?) What is the intended final output? Do you want PC-only playback or some disc format such as BluRay or AVCHD? What software are you using to create the linked AVI's? How did you transfer the VHS tapes them to your computer?

    It should be mentioned that VHS tapes will play on SVHS machines as VHS, not as SVHS. The only way to get SVHS from an SVHS player is to record to SVHS in the first place. Playing a VHS tape in an SVHS player does not "convcert" the VHS tape to SVHS. You should also know that "SVHS" and "S-video" are two different things. SVHS is a type of video formatting on tape. s-video is a type of cable that can play VHS, SVHS, DVD, and any other analog video source. Playing a video through an s-video cable does not convert the source to SVHS.

    Yes, I understand the different, but the svhs player has the Y & C Signal, so this is better than Composite and I read that it has a bigger size. I think VHS has 320 x 200 Pixel, S-VHS 640 x 480 Pixel.(in Pal, don't know how it is in ntsc)
    Yes, a vhs tape in a svhs player makes it not a svhs format, but it is better, anyway.

    I found so many sites with tips and tricks, why you should use an svhs player, tbc and so on in the last year, but nobody knows my problem that I have.

    That the avis are not rendering in the right parameters is my fault.
    I do it quickly, I know it's wrong.
    At the end i wanna make a DVD, but at first I must pass my biggest problem.
    When I "kill" the shadows, then I can go on with the right capture methode and so on.

    I have tested so many svhs machines from different companys, consumer and broadcast machines and with all machines I have the shadow problem. With one player more, with others less.

    My biggest problem are the shadows. Look at the videos, but not the black "3d" shadow, the shadow behind, no lets say to their right of some texts or logos. They aren't constantly in the whole picture of the video so I don't know this phenomenon and since 1 year I search for a solution. But nobody can help.

    PS: Sorry again for my english .

    It isn't just over sharpening. It has more ghosting and ringing. By the time you repair the SVHS, it will look just like the VHS. Would be quicker to just sharpen up the VHS.

    Again, those are oversharpening halos. Turn down the sharpening filter on the SVHS deck. Or use dehalo_alpha(). Yes, it will reduce the detail in other parts of the picture a bit too.

    The VHS cap has no detail in the rug or the rug. The diagonal lines behind some of the graphics is gone too.

    Some of that is from the Xvid compression.

    Then I'd make no conclusions. The video has obviously been re-encoded a few times. No wonder it's soft and starting to look grayed.

    When there is a good sharpen filter, OK. I tried some but the resolutions were not so good.
    I digitalised 80% with my VHS recorder, so when I have a good sharpen filter, I can life with this capture and I save lot of time

    The Ghosting from the SVHS Player you mean I think comes from the NR Filter, in the future I can turn it off and turn the shrapness from "Edit" to "Normal" Mode. Thats no problem.

    BUT you guys don't understand, which shadows i mean. (It's a bit difficult for me to tell that in english)
    The orange marked areas I mean.

    The shadows which you mean, is correctly, bad too. So I do the Dehalo_alpha(ry=0.01, rx=3.0) in future.

    Exactly, that is why I will take a SVHS player. Or sharpen the VHS Captures. But when no linbes are there, I can't sharpen it
    But I can try, when there is a working filter.

    You can try cleaning your video heads, but I don't think the contrast "burns" or smearing will go away. Try cleaning anyway. The problem with JVC players is that if you turn off "Edit" mode and go to "Normal" mode, the output will look more like your VHS player. If there is a separate sharpener/enhancement menu item called "Digital R3" or something similar on your player, turn it off.

  17. You might try darkening the picture, shifting it to the right, then adding it to the original (maybe with a mask of only the light to dark edges).

  18. For testing: I want to take the dehalo_alpha filter. But how I use? For example with the default settings.
    http://avisynth.nl/index.php/DeHalo_alpha

    I got

    AviSource("schärfe2.avi")
    ConvertToYV12(interlaced=false)

    and then, where must be the numbers...?
    Quote Quote  
  19. I forget exactly what values I used but it was something like: dehalo_alpha(rx=4.0, ry=0.1)
    Quote Quote  
  20. So my script is:
    AviSource("schärfe2.avi")
    ConvertToYV12(interlaced=false)
    dehalo_alpha(rx=4.0, ry=0.1)

    It says There is no function named DeHalo_alpha .

    It's not a DLL, but a function. You have to have both it and a couple of DLLs on which it depends:

    http://avisynth.nl/index.php/DeHalo_alpha

  22. Import dehalo_alpha.avs into your script:

    Code:
    import("C:\Program Files (x86)\AviSynth 2.5\plugins\dehalo_alpha.avs")
    Change the path if it's different on your system.
