Editing Guidelines Please remember these guidelines when editing a film article: If a non-film article already exists with the name of the film that you are trying to create an article for, disambiguate and use (film) in the title: Film Title (film) For more information see: Wikipedia:Naming conventions (films) When writing an article about a particular film, the general format should be a concise lead section, followed by a plot summary of no more than 900 words, production details, a cast list, a reception section, and references. Create an Infobox that tells all pertinent information about the film.

"All Betacam SX equipment is compatible with Betacam SP tapes." This is inaccurate; but I'm not sure enough about what IS accurate to make the correction. At the network-owned TV station where I work, some Betacam SX decks are marked analog/digital, and can play back both formats. Some are marked "digital," and can only play SX tapes. None of them can record on SP tapes. I don't know what the siutation is with cameras at all. Can someone update this? David Fell 12:52, August 11, 2005 (UTC)

I could be mistaken on this, as no facility I've ever worked in has realy acquired on SX, but I believe the tape formulations of SP and SX are the same, and that all SX gear can record an SX signal on SP tape. The ability to playback SP may not be present and the ability to record SP is very unlikely to be, but I believe SP and SX tapestock are interchangable. That is certainly what I recall from the Sony marketing stuff at the time Sycophant 22:21, 21 March 2006 (UTC)

Sycophant is correct. To reinterate, SX machines can only make SX recordings, while some, but not all, can replay analogue SP recordings. The tape formulation used in an SX cassette is the same as that used in an SP cassette and SP cassettes can be used in SX machines to make SX format recordings. 83.104.249.240 15:35, 4 August 2007 (UTC)

"300 lines of horizontal resolution" i didn't change this because i'm not an expert, but shouldn't the number of lines determine the *vertical* resolution?

No. The vertical resolution of analog formats is predetermined by the TV system in use, so discussing it is pointless - it's always 480 or 576 scanlines/frame. Where formats differ is the amount of detail they store horizontally, which is a direct result of the amount of bandwidth available. (300*2)/0.7(Kell) = equivalent of 857 scanlines --Dtcdthingy 19:35, 9 Apr 2005 (UTC)

"Some Digital Betacam equipment can gold standard of formats for standard-definition digital video"

Does this line make grammatical sense? What's it conveying? --Miyabisan 13:13, 12 February 2007 (UTC)

"Typically Digital Betacam found in a blue cassette container."

More grammatical oddities. --Miyabisan 13:15, 12 February 2007 (UTC)

"HDCAM, introduced in 1997, is a HD version of Digital Betacam."

I dispute this assertion. Given that Digital Betacam is the "gold standard of formats for standard definition" it would be much more appropriate to compare it with HDCAM SR, not with the markedly inferior HDCAM with its high compression ratio and 3:1:1 sub-sampling. HDCAM is the bronze standard in my book, with Panasonic's HD-D5 taking silver. 83.104.249.240 02:57, 3 August 2007 (UTC)

[edit] Betacam not s video

I removed the line equating Betacam as an example of S-video. It is more properly component video recording, which is three channels, not two, recorded on tape as Compressed Time Division Multiplex, very very different from an s video recording or signal. --StevenBradford (talk) 02:55, 21 November 2007 (UTC)

[edit] Deck models

The whole section on different deck models is off-topic and barely encyclopaedic. Does someone want to split it off into a separate article (eg History of Sony Betacam decks) or should it just be deleted outright? --Dtcdthingy 18:27, 8 June 2006 (UTC)
