Good URL on VCRs?

  1. Hi,

    My memory is playing tricks on me. I'm sure I read in a VCR manual
    that its resolution was 312.5 lines (I'm in UK so 625 lines). I had
    assumed this meant that VCR showed the same field twice in a frame to
    save tape. But I can't find anything to say if they do or don't. All
    I can find is that VCR tapes are 240/250 lines but I think that is
    something different again.

    All VCRs record both fields. If they didn't it would give picture
    flicker on fast movement amongst other side effects.

    The 240 line is the horizontal resolution.
