  • (diff | hist) . . 8 mm video format‎; 17:26 . . (+62). .Rockclaw1030 (talk | contribs)(Hi8)
  • (diff | hist) . . VHS‎; 14:35 . . (+590). .193.63.174.211 (talk)(Tape lengths: meant to add this additional note earlier. I've found a lot of weird running-time tapes in otherwise perfectly normal retail packaging on my hunt for metre/foot lengths...)
  • (diff | hist) . . VHS‎; 14:27 . . (-31). .193.63.174.211 (talk)(Tape lengths: de-tautologising, and adjusting for -actual- playing time using the correct conversion factors (not basing off nominal minutes length or using the previously stated, incorrect factors))
  • (diff | hist) . . Analog signal‎; 14:18 . . (+1,207). .178.155.33.175 (talk)(Disadvantages: Changed the section title and added content to make it a comparison instead of a put-down of analog.)
  • (diff | hist) . . 8 mm video format‎; 13:26 . . (+480). .Rockclaw1030 (talk | contribs)
  • (diff | hist) . . VHS‎; 13:26 . . (+308). .193.63.174.211 (talk)(Tape lengths: some clarifying colour & italics, extra exposition, etc.)
  • (diff | hist) . . PAL‎; 13:21 . . (+11). .2.104.132.222 (talk)(Countries that have ceased using PAL)
  • (diff | hist) . . VHS‎; 13:16 . . (+85). .193.63.174.211 (talk)(Tape lengths: er, oops. helps if you actually type in all the numbers before hitting Save :/)
  • (diff | hist) . . 8 mm video format‎; 13:14 . . (+79). .Rockclaw1030 (talk | contribs)(Video8)
  • (diff | hist) . . VHS‎; 13:13 . . (+160). .193.63.174.211 (talk)(Tape lengths: been reminded of the existence of these lengths by some labels on a VHS sticker strip I just found (still having to identify some old tapes for transferring for professional reasons...). Less common but definitely not unknown on the mkt)
  • (diff | hist) . . VHS‎; 12:27 . . (-66). .193.63.174.211 (talk)(Tape lengths: hell with it. that just looked plain messy.)
  • (diff | hist) . . VHS‎; 12:25 . . (+3). .193.63.174.211 (talk)(Tape lengths: it would appear I am not very good at wikitable)
  • (diff | hist) . . VHS‎; 12:21 . . (+1,328). .193.63.174.211 (talk)(Tape lengths: "equival"? Never heard of that abbrevia. in English before. Use "equiv" or just "equivalent". Also, what's the "(unknown)" bit all about? have now checked actual lengths of DF tapes etc inc averaging -- actual TIMES to be tidied up.)
  • (diff | hist) . . D-VHS‎; 11:23 . . (-2). .193.63.174.211 (talk)(Tape length and speeds: Wholly ludicrous bit of false precision. No-one is going to actually specify their tape length down to the millimetre (approx 1 vid frame!), even if that's what the "feet" length is *exactly* equivalent to...)
  • (diff | hist) . . VHS‎; 11:20 . . (+2). .193.63.174.211 (talk)(Tape lengths: Sorry, no matter how you slice it, 3.335 / 2.229 doesn't make 1.41 ... nor does the inverse make 0.71. No idea how you arrived at those roundings (2dp still = 1.43 / 0.70). The relationship is NOT (inverse) root-2!)
  • (diff | hist) . . VHS‎; 11:18 . . (+30). .193.63.174.211 (talk)(Recording capacity: The way it was explained to me was SP=tracks fully separate, LP=tracks touching but no overlap (=10-20% loss due to tracking issues), EP=tracks partially overlap (=BIG quality loss). The *length*/raw BW of each track is unchanged!)
  • (diff | hist) . . VHS‎; 11:14 . . (+2). .193.63.174.211 (talk)(Tape loading technique: The drum makes one full turn for every complete frame (2 fields) of video information. PAL framerate is 25fps (x60 =1500rpm), but NTSC is 29.97 NOT 30.0 (=1798.2 not 1800). HowStuffWorks is only a *basic* kids' reference work!)
  • (diff | hist) . . VHS‎; 11:08 . . (+166). .193.63.174.211 (talk)(Cassette and tape design: There seems a per-minute significance to the actual tape speed, which makes calculating the total metre length quite easy once explained. Also bit odd that VHS is officially spec'd in inches but only metric is used here...)
  • (diff | hist) . . Quadruplex videotape‎; 09:09 . . (+217). .71.175.90.196 (talk)(added image quality improvement of videotape over kinescope)
  • (diff | hist) . . VHS‎; 09:08 . . (-374). .193.63.174.211 (talk)(Tape lengths: Never heard of PAL VHS >300 mins, neither has Google no matter how inventive my search terms - only finds VHS *DECKS* with 360/420/480 in their name - and this page. If you can prove they're not imaginary, THEN revert this :-))
