Talk:DV (video format)

Digital8 recording times

I noticed at the end of the page it indicates that 40 minutes of Digital8 video can be recorded on 1 hour 8/hi8 tapes. This doesn't seem accurate, since a 2 hour 8/hi8 tape will hold 1 hour of Digital8 video. Any thoughts? Brock1912 (talk) 07:08, 10 April 2011 (UTC)

PAL tapes in D8 mode can record 2/3 of tape capacity in Hi8 mode, but in NTSC it is only 1/2. 77.113.93.250 (talk) 21:28, 26 October 2019 (UTC)

Encoding / compression

The article does not explain/tell how data in encoded and/or compressed (like saying its raw PCM for audio cds); so is there such a specification ? --41.41.15.225 (talk) 15:13, 25 March 2014 (UTC)

ITU REC.601 wrong information

Currently the information is:

In both systems the active area contains 720 pixels per scanline, with 704 pixels used for content and 16 pixels on the sides left for digital blanking.

And this is a wrong information. First of all, the whole 720 samples contain image, therefore there is no digital blanking, the image in the first 9 and last 9 pixels are overscan and are not visible, when displayed on CRT, second, 704 is the value for NTSC, for PAL it is 702 samples of active image, 52μ sampled at 13,5MHz is 702 samples. Therefore the correct pixel aspect ratio for PAL is 1,094. 77.113.93.250 (talk) 21:34, 26 October 2019 (UTC)

DV → DV (video) – (open to other suggested modifiers, like (format) or (video format)) No primary topic for this digram. Attempting to measure long-term signifiance, searches on Google Books, Scholar, and Search all have very mixed results, including for this video format, distance vector, dating or domestic violence, Diversity Visa, etc. Hameltion (talk | contribs) 20:38, 1 December 2023 (UTC)

• Oppose. Nothing else other than the newspaper is actually titled DV, and this does appear to be the WP:Primary topic for "DV" (pageviews). The other articles mentioned are rarely if ever going to be searched for using "DV", so the hatnote pointing to the dab page is sufficient. Station1 (talk) 22:14, 1 December 2023 (UTC)

  Thanks for bringing up usage, I should've mentioned that. The video format does not seem to have a strong case there. Here (see table at bottom) are some other two-letter topics and disambiguation pages: BP (disambiguation) gets 1.3% the pageviews of BP, pH (disambiguation) gets 1.4% of pH, CD (disambiguation) gets 2.2% of Compact disc, LG (disambiguation) gets 5.8% of LG—and DV (disambiguation) has 17% the views of DV.

  I agree that 17% (it's 10-12% more recently) is well above average for a dab page, but even so, 17% is an indication that only a minority of readers are not at the article they're seeking, and that the hatnote is working for that minority. Station1 (talk) 06:12, 2 December 2023 (UTC)

  I mean, that's a really big minority relative to BP/pH... and a two-letter title ought to have a pretty strong case for significance too. Hameltion (talk | contribs) 01:38, 3 December 2023 (UTC)

• Weak support Domestic violence has 37,825 views, Diversity Immigrant Visa has 6,482, Diana Vreeland has 6,372 and Delta-v has 5,696 compared with only 4,213[[1]] for this one. Google mainly returns deo volente and domestic violence. Crouch, Swale (talk) 18:00, 3 December 2023 (UTC)

DVCPRO HD L-cassette maximum length

The maximum length for DVCPRO HD L-cassettes has made some confusion for me. While maximum length for DVCPRO L-cassettes is 126 minutes in DVCPRO25, these can record 31.5 minutes of DVCPRO HD video. Otherwise, 32-minute DVCPRO HD L-cassettes could record 128 minutes of DVCPRO25 video? It is the true maximum length of DVCPRO large cassettes or numbering error?
