redundant mention of weather map applications in intro paragraph and within article - Johnjosephbachir 01:24, 5 Dec 2004 (UTC)

I agree. I don't have time to deal with it now, but I added a cleanup tag. cluth 08:25, 5 February 2006 (UTC)[reply]

Arthur Widmer

Why is there no mention in any of the articles of Arthur Widmer, the inventor of BlueScreen? Seems none of the articles are complete, and so to merge at present would seem unwise/premature Rgds - Trident13 17:04, 4 June 2006 (UTC)[reply]

I disagree. It is true that none of the articles are complete, but attempting to rectify this in any one article would likely involve adding redundant information. IMO, it is preferable to merge the articles first, then begin to fill in the holes in the collective information. --IntrigueBlue 09:55, 30 August 2006 (UTC)[reply]

CSO

My knowledge (and limited research) shows that the term CSO is only used by the BBC, oither UK broadcasters use the term Chroma Keying (ITV for instance) --Jmptdc 13:35, 20 July 2006 (UTC) =: I agree. (I don't have a print source for this, but the subtitled commentary on my Doctor Who DVD tells me about it...) 72.147.60.53 02:42, 6 September 2006 (UTC)[reply]

Merge with Bluescreen

~~I agree that Bluescreen should be merged into this article.~~ --WikiCats 14:37, 6 September 2006 (UTC)[reply]

Bluescreen and greenscreen are types of chroma keying!

Yes, but they it is essential information. It should be merged, along with Greenscreen. --Ksong12 13:25, 5 April 2007 (UTC)[reply]

Yes, they should be merged. --24.238.178.85 21:39, 8 April 2007 (UTC)[reply]

Wait a minute: all these terms, in both film and video, relate to systems of compositing. That article needs work, though it's generally OK as far as it goes. Also, the static or traveling matte pre-digital film technology also used blue (or other color) background screens for compositing. I don't think we've yet found the top of the subject hierarchy here. Jim Stinson 03:35, 31 July 2007 (UTC)[reply]

Come to think of it, front and rear screen projection are forms of compositing, as are the glass shots used to combine action with painted set extensions on the original camera negative (The long road up to Ashley Wilkes' plantation in Gone With the Wind is a classic glass shot.) Jim Stinson 20:15, 31 July 2007 (UTC)[reply]

Merging bluescreen

I also agree that the article bluescreen should be merged into this, since bluescreen is a subset of chroma keying.

I am changing my vote on merging this article with bluescreen because Chroma key is about television and Bluescreen is about film. They should be separate but have references to each other. --WikiCats 10:50, 13 September 2006 (UTC)[reply]

It seems that the proposed merge has not yet happened, so I would also like to go on record supporting a merge of Chromakey, Bluescreening, and Greenscreening. IMHO, the merged article belongs under Chromakey. Bluescreening and Greenscreening make sense as redirects to a merged article under Chromakey. Bluescreening is not unique to film at all. Chromakey with video does tend to use a green background instead of a blue one, but this is far from universal. I've probably done very nearly as much compositing where I had to key out blue in video as I have with green. The techniques and concepts are identical. Forkazoo 23:49, 26 July 2007 (UTC)

I think that they're the same thing, or at least so close that they could be covered accurately by a single article. I don't think anyone looking for information on one will be discouraged by information about the other being present in the same article. Gregory j 11:12, 20 September 2006 (UTC)[reply]

I agree that blue screen is a subset of chroma keying. There should be a section in chroma keying that talks about bluescreen as an application, while the search "bluescreen" redirects to the chroma keying article. zapp645 7:11, 19 October 2006

I think there is a certain amount of duplication between the two pages, but they are about (slightly) different topics. Bluescreening is the term known by most people so should remain active, even if only to site a reference to chroma-key. Alternatively how about Chroma Key (Bluescreening)? --A320sean 19:46, 18 February 2007 (UTC)[reply]

I agree that the two articles can be merged but wouldn't it make more sense to merge this article into bluescreen with a redirect from Chroma Key to bluescreen? After all, bluescreen is the larger of the two articles and this one could easily be made to fit into it. The subject matter is practically the same. I know that bluescreen is technically just a part of chroma keying but it is by far the more well-known term and so it would be easier for readers if that is where the information was as they would be more likely to search that one first. Silent Mime 23:27, 27 February 2007 (UTC)[reply]

But the point is that bluescreen is a subset of the chromakey as a function. So is greenscreen or other new reflective material screens. They should all be combined into the chromakey article and subdivided there into their respective subsets.

Picture?

This article really needs a picture. I'll try to find one, unless someone else already has one.

Jim Henson demo

I recall seeing a special on TV in the 80s on the making of the Muppet Show where Jim Henson and a (real) lion sat against a bluescreen appearing to be in a computer-generated room, and they switched back and forth between a composited and an actual view for demonstration. For further demonstration he put on a blue tie (which the background showed through). I think this was an excellent intro to the technology, especially for kids. I'd add a reference to the article, but can't remember enough details to cite it. I hope someone else might have better luck. Deco 17:12, 16 November 2006 (UTC)[reply]

Use in Australia - relevance?

Is the use of this technique limited to Australia, and if not why is this worthy of the article? The technique has been used in most broadcast news in most countries since the mid-late 90's. I'm removing this section. If anyone wants to add it back in with an explaination of WHY it is pertinant to the article please go ahead. The section removed read: Use in Australia National Nine News bulletins in Australia are always broadcast using the green effect background. At TCN-9, where the majority of national bulletins are broadcast, the same newsdesk is used for the morning news, afternoon news, the 6:00pm news and Nightline. Briefly in 2004, Seven News in Melbourne was broadcast with a shot of Melbourne in the background. This was used from August 2004 until mid-2005. Ten News in Adelaide is broadcast using the green effect background. The shot is of the Adelaide River with the Ten News logo in the middle. This version is actually broadcast in Melbourne to save on costs.

New compositing article

The use of blue screen (aka green screen and chroma key)in visual effects is included in the new article Compositing. Jim Stinson 22:58, 10 August 2007 (UTC)[reply]

Horrible Merger

Why has Blue screen been redirected to the out-moded term Chroma Key? Merging is a good idea, but merging from one specific term to another specific term, instead of a more general categorical term only adds inaccuracy. Chroma Key is a video only process that has gone out of favor for the most part. It certainly isn't used by the film industry and most video production artists today. Motion Image Compositing (or something else) would be a much better general term. --StevenBradford 22:18, 8 September 2007 (UTC)[reply]

Advertisement POV

I removed this text from the "Even Lighting" section because it sounded like advertisement:

“

Recently a much simpler and easier way to create an evenly lit background has been developed. By using screens made from a retroreflective fabric illuminated by a ring of LEDs around the camera lens it is possible to produce very even bright blue or green backgrounds whilst only consuming around five watts. Products such as Reflecmedia's Chromatte and LiteRing systems enable chroma key backgrounds to be created very simply and quickly, freeing the user to concentrate on lighting the foreground creatively. The systems are extremely energy efficient and enable users to create virtual studios in areas where space and energy are at a premium.

”

I ran a check on the IP that added the text, 81.187.36.194, and it's registered to "REFLEC-PLC", the same company as Reflecmedia, the company mentioned in the text... Hmmmm... Interesting. Sbrools ^{(talk . contribs)} 17:21, 2 November 2007 (UTC)[reply]

Video vrs Film

I understood that the term "Chroma Key" only refers to the VIDEO process of blue screen. The process for doing this is totally different when performed on video instead of film, and because of digital intermediates, the film version that is described at length is now obsolete. Doctor Who made extensive use of Chroma Key starting in 1970. -- Algr (talk) 19:07, 16 November 2007 (UTC)[reply]

Adobe Flash

Cant Adobe flash do greenscreen by making a background movie clip and making another layer with a different movie clip? Shouldnt this be mentioned in the article?71.53.20.131 (talk) 00:21, 5 December 2007 (UTC)[reply]

Flash can output files that include an alpha channel. This is created by simply recognizing areas that have no objects on them - there is no need to make special layers or background clips. One would not call this "Chroma Key" however, because the alpha channel has nothing to do with the color of any object, but is instead is rendered from the geometry of files. A rendered alpha channel is invariably superior to chroma key, because you don't need to worry about color ranges or reduced resolution of color channels. You can also have transparent objects in the flash file allowing the background video to show through. Algr (talk) 07:03, 5 September 2008 (UTC)[reply]

paulscottfilms@yahoo.co.nz Paul Scott This discussion page seems far more technical than the article. I would say it is difficult to deal with a technical issuse like chroma key without use of specialised words, with exact meanings —Preceding unsigned comment added by Peterquixote (talk • contribs) 05:15, 27 April 2008 (UTC)[reply]
