Video codecs<>formats

In a lot of article's the words codec and format are used interchangeably while this is NOT the case. A codec is a piece of software that encodes/decodes to a video file format. A format is a set of agreements on how to present information digitally, including stuff like compression and encryption, as is the case with picture and sounds. [1]

Important: when refering to video format, it goes to the page video which isn't very explanatory. There should be a section on the page named formats about video formats. --Thelennonorth (talk) 16:09, 7 January 2010 (UTC)

Link deleted for video file extensions

I tried to add a reference with an external link for a list of video formats by file extension (which I find very useful, considering this isn't already written in the article and was directly linked to the article section I tried to edit) and my edit was immediately reverted by MrOllie, on whose Talk page I can not write because it's protected. Don't you think such a list would be useful? The external link was to an article, on a non-commercial, reference website. What did I do wrong? Yehonala (talk) 14:26, 22 January 2009 (UTC)

Example of Video

it seems that the wiki for video would contain an example of a video, or even a few consecutive photos set in motion, like a flip-book. wikipedia abounds with pictures, yet the wiki for "video" contains no videos? YOUareTIGERBAIT (talk) 19:40, 4 March 2008 (UTC)

'Most Video Taped Day

This one line mentions the September 11, 2001 was the most videotaped day in history needs some work...does anybody know why it was so? All I can think of happening that day was this: http://en.wikipedia.org/wiki/September_11_terrorist_attacks But I'm not sure if the attacks could be responsible for increased video capture, and at least not enough to cause a record. In summary, elaborate. I'm curious and incapable of research. —Preceding unsigned comment added by 64.228.3.53 (talk) 00:28, 25 February 2008 (UTC)

Meeds something about the 1" vtr format as well...name, anyone???

VGA

No mentions of VGA?

Wikipedia video policy

Halló! I am new at Wikipedia. Question: Are there some similar topics for video as for image (Wikipedia:Images Wikipedia:List_of_images ...)? Gangleri 14:04, 2004 Sep 25 (UTC)

360 degree videos

Is there any information around about 360 degree videos? There are already digital camera's that do this, but would be interested to know if such technology exists for video.

They had a "ride" at disneyland that was a 360 degree video. If you didn't already see it... too late... they got rid of it for good reason.

Video=Videocassette

The article currently says that in the UK the term video is used to refer to a videocassette. This suggests that it is limited to the UK, but I've heard it used that way as well in Southern California. Is there in fact any English-speaking area where the words video and videocassette are not interchangeable? Theshibboleth 22:51, 19 November 2005 (UTC)

VHS "bit rate"

This line needs correcting / removing / explaining: "For example, VHS, with a bit rate of about 1 Mbit/s" VHS of course is an analogue format (and a crap one at that but there we go), so of course it has no bit rate associated with it. Anyone feel like tidying this up? colin99.

That rate probably refers to the amount of digital information in VHS-to-NTSC, NTSC-to-VHS, VHS-to-PAL, or PAL-to-VHS conversion, but I'll try to verify that. The Rod 15:26, 9 January 2006 (UTC)

PAL, SECAM and NTSC

The line:

"PAL (Europe) and SECAM (France) standards specify 25 fps, while NTSC (North America)"

is imprecise changed it to what it says for formats Old Analog section although thats pretty imprecise as well

Film vs. video

The intro and second paragraph say that film is a kind of video, but only non-film formats are treated in the rest of the article. To me (and many others, a quick google reveals), video is explicitly not film. The crux of the definition of video in the first sentence of this article is moving-picture technology for tv or computer monitors. Am I missing something? Is there any reason to define celluloid film as video? ntennis 01:42, 14 April 2006 (UTC)

What other word would you use to include all moving images, both on small monitors and on the big screen ? As opposed to, say, "sounds".

--65.70.89.241 19:18, 1 August 2006 (UTC)

We used to say "motion pictures" or "moving pictures" and you now tend to hear simply "film". But ntennis is definitely correct: the visual portion of film isn't "video"; video is an electronic representation of an image.

Video Recording + Screencast

Added a Screencast ref to 'See also'. Also I'm concerned there is limited info on 'Video Recording' perhaps with links to decent HOWTOs. There isn't a 'Video Recording' section in the parent page Video, to which 'Video Recording' is redirected. Should there be a separate page (instead of redir) or section for the large topic of 'Video Recording'? Awildman 22:33, 8 September 2006 (UTC)

Stereoscopic Video

In this paragraph:

"One channel with alternating left/right frames for each eye, using LCD shutter glasses which read the frame sync from the VGA Display Data Channel to alternately cover each eye, so the appropriate eye sees the correct frame. This method is most common in computer virtual reality applications such as in a Cave Automatic Virtual Environment, but reduces the effective video framerate to one-half of normal (for example, from 120Hz to 60Hz)."

Stereoscopic video applies to much more than VGA, and furthermore, it is unlikely that the frame sync comes from the Data Display Channel. Please provide details and/or a credible reference, or this will be changed. Agrjlc (talk) 00:14, 23 October 2009 (UTC)

how are audio and video different from other media? — Preceding unsigned comment added by 195.194.215.249 (talk) 13:25, 1 September 2011 (UTC)

Usage of the word

What's still critically missing is when the term was coined and then adopted into general usage. I'm pretty sure that people still simply said "TV" or "television" long into the 1970s. Heck, even today many people still call it a "film" when it's actually a video clip! --2.240.185.54 (talk) 09:03, 24 July 2014 (UTC)

To my surprise, I've now come upon an early TV series called Captain Video and His Video Rangers that was broadcast on DuMont since 1949. According to the series's German article, Cpt. Video derived his name from his so-called opticon scillometer, which was a television set that he used to oversee the activities of all his agents on earth. --2.240.185.54 (talk) 09:28, 24 July 2014 (UTC)

Divx

Why isn't Divx, the failed Circuit City format that came out in the late 1990s and was a rental vehicle for movies, not included here? If I don't get a good reason, I'll add it. — Preceding unsigned comment added by Rricci428 (talk • contribs) 06:41, 22 June 2017 (UTC)

That's covered at DivX and Video codec. I assume you'd want to add it in Video#Transport_medium. That whole section needs work but I don't have a good reason against adding more to the pile there. ~Kvng (talk) 15:04, 10 February 2018 (UTC)

Rricci428 meant DIVX, not DivX. It could be added in the Discontinued optical disc storage formats section. But I'm not sure DIVX was important enough to list it there. Probably not. (As for DivX and video codecs, they are not the subject of this article. The Digital encoding formats section lists encoding formats such as H.264 or MPEG-4 Part 2, not codecs like DivX.)—J. M. (talk) 15:55, 10 February 2018 (UTC)

Component video

Below the image of the component connector it says: "Component video (3-channel RGB)". Isn't it supposed to be 1 channel for luminance and 2 channels for chrominance?--Loquetudigas (talk) 14:55, 13 May 2016 (UTC)
There are multiple ways to do analog component video. RGB is the original one, and is the way video originates off the prism block in a three chip camera. The most popular varian is Y, R-Y, B-Y, also sometimes called Betacam component. It's a more bandwidth efficient way for transmitting component video. see https://en.wikipedia.org/wiki/Component_video StevenBradford (talk) 05:40, 16 May 2016 (UTC)

I have corrected the caption based on how the same picture is treated at Component video. ~Kvng (talk) 15:35, 12 April 2021 (UTC)

Spherical Volumetric Video

This article mentions neither spherical nor volumetric. WHY?? oh, why?

Digital video consumer and professional

About "It could not initially compete with analog video, due to early digital uncompressed video requiring impractically high bitrates.": I would start this sentence with "in the home, it could not...". Then I would add the explicit professional uncompressed digital VCRs. One is found on an already existing wiki page "D-2 (video)" and another wiki page is "D-1 (Sony)", also professional and uncompressed digital video. Ohgddfp (talk) 16:11, 5 June 2022 (UTC)

IIRC, these professional digital formats did not replace analog when they arrived. The machines and tape were expensive and the systems were temperamental. The could not compete statement was arguably also true for professional applications. Digital did not replace analog video in professional or consumer applications until data compression and more robust storage formats were available. ~Kvng (talk) 12:50, 8 June 2022 (UTC)

In the "History of Television", it is claimed that Sony had sold more than 1,500 D - 2 recorders. These professional machines are uncompressed digital video. Sony D1 professional VCRs were popular in high end post-production facilities. I personally demonstrated them. If the numbers of D2 units sold is too low, (and the volume of professional machines is always low anyway), then that distinction should be spelled out in the article. Ohgddfp (talk) 13:12, 8 June 2022 (UTC)

History - 1920s?

The Washington Post says: "The birth date and birthplace of the VCR depend on how far back you want to look. Video recording technology itself dates to the early 1920s, but the company Ampex is credited with developing the first commercially viable videotape recorder in 1956. The machine was bulky, expensive and designed primarily for professional broadcasters." The article ought to have some reference to what video technology was possible in the 1920s. Presumably, since magnetic tape was not invented, it must have used a disk system? 2.31.164.0 (talk) 15:30, 20 June 2021 (UTC)

Maybe you did not notice the link to History of television at the top of the History section here? ~Kvng (talk) 13:02, 23 June 2021 (UTC)
