[QUOTE="spiney, post: 243486, member: 192438"] All 1960s stuff, including Dr Who, was on qaudruplex, slowly replaced by C format from early 1970s, for timescale see above BBC link. Qadruplex was "solid", the tape is robust, a lot of them have lasted well! Trouble is, there aren't many machines left, and they're full of analogue circuitry that constantly needs tweaking. Later formats are electronically more stable, but the tape is more fragile ... Current digital recorders are mostly the "D" series, varying hugely in capabilities, a good comparison guide is: [url]http://videoexpert.home.att.net/artic3/256atab.htm[/url] . [url]http://videoexpert.home.att.net/artic3/262ctab.htm[/url] . [url]http://www.theiabm.org/pdffiles/video.formats.pdf[/url] . Tape archiving: [url]http://www.amianet.org/publication/resources/guidelines/WheelerVideo.pdf[/url] . When you see a camera crew filming somebody in the street, for a news story, that's usually Digital Betacam. [/QUOTE]
