Brian, I'm not quite sure I understand your question, but here goes. If your 3/4 machine is more than say 5 years old it probably would have specs that put it roughly comparable to standard VHS (about 230 lines of color resolution). Later vintages would sometimes spec out at about 260. "S" output is rated at up to 430 lines when used in Y/C mode, composite output is still no better than standard VHS. The wideband mod that I have referred to in previous postings will add about another 100 lines of resolution (Composite color) to whatever your 3/4 deck starts from. I usually do my field aquisition with 3/4SP, but lately I have been using "S"-VHS-C with good results, depending on the lighting conditions. I ALWAYS dub (Thru a transcode TBC) my master footage to work footage (3/4SP) then edit to MII. On the whole, I can't really say that I see much difference in the formats once the footage is edited and viewed side by side, except that there are definite color artifacts (certain colors of orange and red) in the "S" domain, that I don't see in 3/4SP. I guess it all depends on whether or not you are shooting traffic cones or squad cars. Frank
