Good URL on VCRs?

Jan 30, 2005 1 Replies

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.



TIA

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.
