    Any software to clean up captured SVHS video, make it less noisy,
    sharpen it etc?

    Stand alone software please.


    Bye for now.

    Clive.

    There are many software filters available, but most sharpening of
    images tends to increase noise and noise reduction tends to blur the
    image. However, a median filter can lower noise with what looks like
    maintaining resoultion. I don't know of any software that does this but
    suspect it does exist..
    I expest that anything you will find will be part of a general video
    editing software package.

  3. Hi Clive,

    Assuming you want to convert the captured SVHS video to DVD, here are
    some points to keep in mind.

    1) Clean the tape heads on your analog VCR or camcorder. Older tapes,
    especially, can deposit a lot of residue on the heads, resulting in
    dropouts and other picture flaws.

    2) If your VHS VCR has a sharpness control, turn it down. A softer
    image has less noise and that enables the MPEG-2 encoder to do a much
    better job. Some tape players also have an "Edit" button which affects
    playback sharpness. Put it in the position that provides less
    sharpness.

    3) Connect a video processor to the output of your analog tape player
    and then connect the output of the processor to your capture device.
    So-called "proc amps" and timebase correctors (TBC's) provide tools for
    stabilizing analog video, changing brightness and contrast levels and
    adjusting color. Just being able to adjust levels and color can result
    in a DVD that looks much better than the original VHS tape.

    4) If your want to convert Hi8 and 8mm to DVD, one of the best ways to
    import it into your computer is with a Digital 8 camcorder. Several
    models of D8 camcorders can playback analog tapes and convert them to
    DV and have built in digital noise reduction and TBC's to clean up the
    analog video before it's converted to DV and sent to your computer via
    the Firewire cable.

    5) If you transfer two hours of VHS to a DVD it can result in a
    significant loss of quality unless you have a high quality MPEG-2
    encoder or use methods that encode the video at "half resolution." The
    normal DVD video resolution is 720x480 for NTSC, but some encoders and
    DVD authoring programs allow you to use 352x480 resolution. When you
    convert VHS to DVD this smaller resolution can still deliver very good
    results at the low data rates (bitrates) required to fit two or more
    hours of video on one DVD, especially if you use an analog-to-MPEG2
    encoder or a standalone VHS to DVD recorder that bypasses the
    analog-to-DV step.

    6) Try to use compressed audio on your DVD's. Uncompressed - PCM -
    audio takes up a lot of space on the DVD that could better be used for
    higher-quality video. Dolby Digital/AC3 is the best choice for audio
    compression.

    A warning: if you do convert your analog video to DV before putting it
    on DVD, don't be shocked when you see the size of the DV file it
    captures to your computer. DV files take up almost 14 gigabytes per
    hour and every so often I answer a question from someone who wants to
    know how in the world they're supposed to fit a 14GB movie on a 4.7GB
    DVD? That's what the MPEG-2 encoder does: it compresses the video to a
    much smaller size so that video, audio and menus all fit on a DVD
    (which actually holds 4.37GB of computer data).

    If the analog-to-DV option sounds likes the best one for getting your
    video into the computer when you start to transfer VHS to dvd and you
    don't already own a DV camcorder or one of the analog-to-DV converter,
    I recommend getting a DV camcorder with analog inputs instead of simple
    converter box. The DV camcorder will allow you to save your edited
    projects back to tape as a high quallity DV master and, you will have
    something to shoot new video in the DV format.

    Some DV camcorders cost only slightly more than a converter. If you
    have a lot of old Hi8 or 8mm tapes, then consider purchasing a Digital8
    camcorder with analog inputs and the ability to playback those older
    analog 8 tapes. In addition to "analog inputs," some camcorders also
    advertise "analog pass through." This means that the analog signal does
    not have to first be recorded to DV tape before being sent down the
    Firewire cable as DV. This can save plenty of time and tape if you plan
    to do a lot of VHS to DVD conversion
