Thank you very much for your input, sanlyn
Hmmm... I wonder if maybe the PAL model is very different from the NTSC model on these units? ...cos there is a great difference when switching the NR button between "ON", "OFF" and "EDIT" on my Panasonic NV-FS200. When turned "ON", there's noticably less noise/grain but it becomes a bit blury in some scenes. In "EDIT" mode, it is sharper, more grainy and with richer colors than in "OFF" position.
But the biggest difference happens with my Panasonic NV-HS960. It has a "3D DNR" button. This makes a HUGH difference when turned on. Some times it's good, some times it's "bad".
I just wonder if there's a "rule of thumb" of when to use it and when to leave it off when digitizing VHS footage?
Does it remove any kind of noise that can't be removed by applying filters in post?
