"HD in film-making" section
[edit]where does this 'data' come from?
"The four major film formats provide pixel resolutions (calculated from pixels per millimeter) roughly as follows:
- Academy Sound (Sound movies before 1955): 15 mm × 21 mm (1.375) = 2,160 × 2,970
- Academy camera US Widescreen: 11 mm × 21 mm (1.85) = 1,605 × 2,970
- Current Anamorphic Panavision ("Scope"): 17.5 mm × 21 mm (2.39) = 2,485 × 2,970
- Super-35 for Anamorphic prints: 10 mm × 24 mm (2.39) = 1,420 × 3,390"
there is no citation provided for it, nor details of the film-stock which supposedly has this 'resolution', nor any mention of the differences in contrast handling, image-noise & so forth.
some evidence or it goes.

Impending removal of the "World Wide Web HD resolutions" table
[edit]I worked on this table a number of years ago, but it's rarely been updated since. I'm working on a larger project to merge together a number of existing pages and tables related to "video hosting services" (see the discussion). As with my comment (made in 2009) about our futile attempt to compile a comprehensive list of all movies "filmed in HD", it seems unwise to attempt to compile a list of all video hosting services and their parameters/features. As I proceed with my project, I'll be removing this table and linked to a page about video hosting services. — Preceding unsigned comment added by Rburriel (talk • contribs) 17:35, 2 November 2017 (UTC)
- If a table isn't comprehensive enough, or is too much work to keep up to date, we should at least retain a few cited examples of the historical and present state of streaming Internet video services to hold them accountable for their lies. Things have generally improved since the “worse than SDTV DVD ‘HD’” streams of the ’00s, but even with the latest codecs they're still overcompressing “4K” too severely to keep up with broadcast HD, let alone UHD BDXL. 2600:1700:2B30:2060:55FA:88D5:9B2A:3B28 (talk) 14:10, 28 July 2024 (UTC)
- The table appears to be well sourced. Covering notable hosting services seems to be an easier task than covering individual movies. We need more discussion before giving up on this. ~Kvng (talk) 14:48, 1 August 2024 (UTC)
1080i, full? no
[edit]1080i has never been, nor considered, to be FULL HD. Only progressive 1080 is or has been. — Preceding unsigned comment added by 47.6.223.50 (talk) 06:29, 1 September 2021 (UTC)
