I'm not super-technically minded on the editing side, but am currently doing some comparative tests transferring SVHS-C tapes to DVD, using the quality, powered Panasonic adaptor to compare the results from my 2 vcrs - ('down'n'dirty' I know).
Panasonic NV-HS1000 (TBC on, AI off, picture SOFT) s-video > JVC DR-M100 (xp mode, Verbatim disc)
JVC HR-S8700 (TBC on, picture control AUTO) s-video > JVC DR-M100 (xp mode, Verbatim disc)
I feel both machines are in equally good working condition; I've tried various tapes (the usual thing, family life, interiors with low light levels; alongside holidays outdoors, car racing, air shows, etc).
Playing the DVDs on a Blu ray player to a 50" plasma screen to give them the (harshest?) test of detail/quality, I'm really happy with the clean image output from 8700 > DR-M100.
I've tried the Panasonic's picture slider variations between Softest and the Mid setting, but always aware of that 'film' of noise. Even though I can appreciate it may retain detail in certain areas that the JVC machine smoothes out, I prefer the JVC 'look'.
I have just seen a Panasonic NV-HS960 for sale online and wondered if there would be a significant difference in the image quality of the venerable NV-HS1000 and the (relatively!) new NV-HS960, or if that is the Panasonic 'look' carried through every updated model.
