Horizontal bands on old VHS tapes

Solved

Hello,
I just bought a Grabby Terractec Magix, the transfer to PC is going well, but I would like to remove the red bands at the bottom of the image and improve the images if possible. These are VHS videos either purchased or movies I recorded from TV, so they are quite old VHS tapes. I haven't found this kind of settings
Thank you in advance to everyone

Configuration: Windows 7 / Internet Explorer 9.0

    Hello, the result of your transfer can only be judged once the film is finished, burned, and viewed on a home television screen.

    If, when watching on a TV, you have the same problem (red band), it’s a storage issue with the video tape (band compressed)

    and if you have an old TV, you can use the RF output of the VCR and the TV to check if everything is working well (since the TV will send you the same image as that arriving at your "grabby")
    as for increasing the quality, the VHS is 240 TV lines of definition
    and to convert it to 900 TV lines, you have to redo it frame by frame
    the simplest is to switch to standard definition (SD)

    Hello
    It may be a problem with the alignment of the read heads of the playback device, as the VHS tapes were not recorded on the same machine.

    I deliberately excluded the head alignment because what you're saying doesn't correspond to that nor even to a problem between an LP/SP recording
    because in that case you would have it at the bottom and at the top aligned in SP mode
    in LP mode you have it throughout the image
    that said, keep us updated
    the remark from Glandu, which is a good one, did you make it? And what does it give?

      Digitization
      Excerpt:
      "But very few people have professional VCRs that offer the possibility to align the heads with the tape.
      Because Video8, 8mm, and HI8 type cameras have fixed heads, and it only takes a shock to your camcorder, a return to service, or even parting with it for the playback of your tapes to show an alignment defect. You need a device capable of aligning itself with your original recording. We have the required equipment; we do not digitize your tapes from camcorders (see our photos).
      And even during acquisition, you digitize with only one top image (bottom right), which results in having black borders on the right side from top to bottom of the screen. This creates a blurred zone that is often red.
      The image is not stable; it shakes. "

      a jc01 your comment is only valid for the LP mode on VHS, here you are dealing with type 8 tapes...
      and the latest G.P recorders have the ability to realign the two heads (pana, sony, jvc)
      and LG like SAMSUNG has incorporated it into their combos (VHS and DVD)
      currently in LG it is the RCT689H
      regarding 8mm hi8 and d8 within the same brand and series there can be a slight displacement (azimuth) of the head and here indeed to correct it the simplest way is to go through a recorder of the EVS or EVO type
      the 8mm tape has more information on its tape than the VHS because with the series of EVS you can put 9 hours of music on the tape (CD quality)
      there you go
