    ok then, i capture vhs video from my canopus, when i use tmpgnc to convert it sometimes the pictures are interlaced (lined when there is movement on screen) and sometimes theyre not ( ie viewed in the tmpgnc viewer) i dont understand why, but some VHS tapes do and some dont, theyre all recorded of the same VHS video on the same type and make of tape, the only problem it causes is shaky stills taken from the final mpeg2 file. ( but i like to capture good stills for the final DVD menu)So my question is when i apply a de interlace filter in TMPGenc these lines(interlacing) disappear. will applying this filter cause the end product (a DVD-r ) to look lined ( interlaced) on the TV screen. the point of the question is so i can get good stills for menus etc, any help wpuld be really appreciated!!!

    If the final destination is an interlaced presentation, then do not deinterlace the video stream. An interlaced MPEG-2 program is deinterlaced by PowerDVD or WinDVD during playback on your computer.

    Maybe what you're capturing just isn't interlaced content - for example, a film from PAL video tape?

    When the source is interlace and your final mpeg is interlace, you don't have stattering problems but you have visible - on tv - vertical lines, it means that you did a bad resizing.

    When you capture for example 704 x 480 and you resize at 720 x 576, you have those problems

    The preview modes are by default de-interlaced, so to show excellent on the PC monitor

    having captured these tapes, i use tmpgnc to encode them, but as i say some captures appear to have "motion lines" on them what i understand to be interlacing, but on the other hand some dont, but they are all recorded on the same vhs pal video recorder, the lines do not show up on the final burnt DVD however, but the problem is , i use WIN DVD to capture stills from the finished VIDEO TS file to use in DVD AUTHOUR, and whenever the capture has these "motion lines" i can never freeze the frame in WIN DVD the frame is blurred whereas a non "motion lined" capture freeze frames perfectly, therefore i can get really good frame captures for dvd authour, as i say these lines only show up in the previews for tmpgenc and dvd authour, I really appreciate you guys helping me out and am sorry if this reads like nonsense but id like to get a solution to the problem, I use the wizard settings in tmpgenc for PAL which are VIDEO TYPE non interlace
    FIELD ORDER bottom field first (field B)
    ASPECT RATIO 1:1 (VGA)

    Can anyone offer a solution why some tapes/captures are "motion lined" and some not!

  6. VHS tape is always interlaced in the sense that it sends 60 (or 50 PAL) half pictures per second to the video output.

    The reason some tapes have interlace lines and some don't is because of the nature of the source. If both fields were taken at the same time (eg, from a single film frame) you won't see any interlace lines -- the two fields can be joined to recreate the original film frame. If the fields were taken at different times (ie field 0 at time 0, field 1 1/60 of a second later, typical in live sporting events, etc.) you will see interlace lines because the two fields don't come from the same picture.

  7. I'll put it another way. If they look good on the TV don't break what isn't broken by de-interlacing.

    To get your stills, Take and use for example tmpgenc plus mpeg tools and cut out to a new file the part you wanr your stll from and then only de-interlace that small file. Much faster that way and it won't mess up your DVD.

    Good Luck

  9. Can't you copy a single frame from VirtualDubMod and use that? I haven't used the mod version in a while but I think you can get it that way
