Thanks Kris - all added!

Any other video definitions you all don't see in the glossary???

Maybe Closed GOP / Open GOP?

Overburn:

According to the official standards, a cd (and a cd-r disc as well) should have a capacity of 650MB or 700MB of data, or an equivalent of 74 minutes or 80 minutes of audio.

As the laser beam in a cd recorder writes on cd-r media, it travels from the center of the disc towards its edge. Before the physical edge of the cd, there is an already set limit to prevent the laser beam writing beyond that, so that the physical edge of the cd's writable surface will never be met.

This means that there exists a security zone at the edge of the cd-r media. If we could write into that security zone, we could gain in capacity, since we would be able to write more data on the cd. This is called overburning.

Ogg Vorbis

Ogg is the name of an open souce multimedia project maintained by the xiph.org foundation. Vorbis refers to the lossy general purpose audio compression format that surpasses mp3 in quality and rivals new formats such as AAC and TwinVQ (a.k.a. VQF). http://www.xiph.org http://www.vorbis.com

Ogg Theora

Theora is the video compression codec part of the ogg multimedia project. It is based on On2's VP3 codec, but On2 has released it now under a BSD type liscence and renounced its patents, so it is now free and open source. A final release is due out in early summer 2003. http://www.theora.org

Both Ogg were added.

Overburn added. Thaaaaanks! Even though it took 3 months to add it.

I would like to see a glossary entry for "CRC" Cyclic Redundancy Check and for the "CIRC" error that sometimes shows up while ripping a DVD with DVD Decrypter.

much thanks.

Dern...I am trying to find the meaning of "VFAPI", even though I have used this software many times for DVD2AVI and TMPGEnc. I would like to see a glossary entry for these five letters. I was looking at Hori' home website but I cannot read Japanese. Does it stand for Video Filter Application Porgramming Interface or something similar?

Can you please look into it.

Hori, VFAPI

how about TGPO? lots of people asking who he is, and there's always people asking about the poll option. just a link to the about page would be fine.

Video Encoding-
The process for changing a video from one format to another by altering the resolution and/or the bitrate.Normally the result of this process is a movie with a different compression.For a proper encoding you need a piece of Software and/or Hardware, which is called codec.

[Dragonsf]

Codec : acronym for "compression/deccompression" , is an algorithm, or specialized computer program, that reduces the number of bytes consumed by large files and programs.

Are you sure?compander is compressor/expander and codec is IMHO coder/decoder- which is virtually all the same.

3GP

DVB - (i'm surprised satStorm hasn't suggested this one!)

The Digital Video Broadcasting Project (DVB) is an industry-led consortium of over 300 broadcasters, manufacturers, network operators, software developers, regulatory bodies and others in over 35 countries committed to designing global standards for the global delivery of digital television and data services.

DVB is currently recieved in the UK through a terrestrial service known as Freeview. The transmissions are in MPEG-2 format, and often in DVD compliant resolutions. they can be captured directly using a DVB-T card, or an external USB device such as the Hauppage DEC-200t. After demuxing with specialised software you are left with DVD-compliant video and audio streams.


A guide on the capping/demuxing process would be nice, if there's someone here doing it already, if not i'll set up a guide once i've got my DVB reciever.

DVD+R Definition
Quote:
DVD+Recordable defines a standard for recordable DVD drives and media defined by the DVDRW Alliance. Often called "plus R", the format is write once (compared to DVD+RW wich can be erased and rewritten). The single sided discs can hold 4,700,000,000 bytes (4.38 Gigabytes at 1024 bytes to the kilobyte) with double sided discs holding twice as much. There are no dual layer single sided recordable discs. This format competes with the DVD Forum DVD-R specification.

DVD-R Definition

DVD-Recordable defines a standard for recordable DVD drives and media defined by the DVD Forum. Often called "minus R", the format is write once (compared to DVD-RW wich can be erased and rewritten). The single sided discs can hold 4,700,000,000 bytes (4.38 Gigabytes at 1024 bytes to the kilobyte) with double sided discs holding twice as much. There are no dual layer single sided recordable discs. This format competes with the DVD+R format.

So I assume all the DVD+R vs DVD-R threads are really DVDRW Alliance vs DVD Forum threads? If that is the only difference between the two, I dont see what all the fuss is about.

Digital8
Camcorder format which allows you to record digital-quality video onto standard Hi8 or 8mm tape. Most Digital8 camcorders also play back analog Hi8 and 8mm recordings, although they do not record in Hi8 or 8mm. A 120-minute Hi8/8mm tape yields one hour of recording when used with a Digital8 camcorder, giving you essentially the same stunning picture quality as you get with Mini DV (500 lines of horizontal resolution).

Mini DV
Mini DV is a video cassette designed for use in Mini DV digital camcorders. The picture quality of digital video (DV) recorded on a Mini DV cassette is basically identical or better to the quality of DV recorded on a Hi8 or 8mm cassette by a Digital8 camcorder. Mini DV can have up to 530 lines of video resolution for some camcorder models. However, Mini DV tapes are smaller which allows for smaller camcorders. Mini DV tapes are available in lengths of 30 and 60 minutes (plus, recording in LP mode lets you extend total recording time with a 60-minute tape to 90 minutes).

VHS
VHS an analog format capable of delivering 240 lines of video resolution, along with stereo sound that's nearly as good as CD (in dynamic range and frequency response). Blank tapes usually feature either 120 minutes or 160 minutes of recording time at the highest recording speed (6 hours or 8 hours at the slowest speed). VHS and VCR's are slowly being phased out in favor of DVD players and other digital tape media.

MICROMV
The MICROMV cassette is the smallest type of camcorder tape to date — nearly 70% smaller than already tiny Mini DV tapes — so it's no surprise that all MICROMV camcorders feature an incredibly compact form factor. MICROMV cassettes feature a built-in memory chip for conveniences like custom title storage and index thumbnails for easy access to specific scenes.

Hi8
Analog camcorder format which allows you to record video with 400 lines of resolution onto Hi8 tape, or 240 lines of resolution onto standard 8mm tape. Hi8 tapes can get up to 2hours in SP and 4hours in LP modes. Most Hi8 tapes will work in Digital8 camcorders but typically only can record 1 hour of Digital video.

Basic descriptions, feel free to add more

Thanks machineman and flaninacupboard!

[Baldrick]

I would like descriptions for these glossaries
pixelation
chroma noise
chroma bug

[vhelp]

Here is something I found (sifting through the web) ...

Chroma Noise

Chroma noise affects areas of colour in the image. Instead of being clean, even areas of colour, chroma noise makes colours look grainy due to random noise being inserted into the colour signal. Chroma noise seems to particularly affect blue, although it can potentially be seen in any large expanse of a single colour. Chroma noise is pretty much exclusively an artefact of analogue video processing, and it is very rare to see it in modern, all-digital transfers. Increased MPEG macro-blocking artefacts are a potential side-effect of chroma noise, as the MPEG encoder attempts to encode the extra spurious random noise, leaving less bits for actual picture information..

@ Baldrick,

I had some time locating this article I found early this year. I thought I had
it bookmarked Anyways..

It's too exahaustive, and I not that keen at breaking 10 paragraphs into one
sentence But you're more than welcome to take a stab at it :P
It's excellent read - the best.

Blu-Ray

(Also known as BD-Rom) Next generation disc format developed by nine companies: Hitachi Ltd., LG Electronics Inc., Matsushita Electric Industrial Co., Ltd., Pioneer Corporation, Royal Philips Electronics, Samsung Electronics Co. Ltd., Sharp Corporation, Sony Corporation, and Thomson Multimedia, as a replacement to DVD. Blu-Ray uses a blue-violet lazer, compared to DVD's red lazer, to write and read information and a smaller disc thickness, .1 mm optical transmitence layer, to allow a larger disc capacity of 27GB for singe side, single layer disc on the same diameter disc as DVD's and CD's, which is 12 cm. Blu-Ray video format uses the same MPEG-2 compression as DVD, but the much larger capacity and max data transfer rate 36 Mbps of of Blu-Ray allows it to contain full High-Definition video. Discs are all rewriteable, the format lacks a write once disc, and are contained in a cartridge much like the first DVD-RAM discs. Sony is currently only selling set-top recorders in Japan which cost $3,800 (US) and blank discs cost $30 (US).

I think the glossary is also missing a definition for S-Video, but I don't feel qualified to write a good definition .

[The village idiot]

Please add the word ****
Def: an explitive often used in the TV industry when something goes wrong, or you make a mistake esp. when that mistake hits air. Even stronger than the word SHIT, as defined earlier.

EX: ****! I punched up the wrong camera.

Also used as a descriptor (adj) This tape deck is FUCKED UP!, The tape is stuck and won't eject.

Also as an abreviation N.F.G. (No ******* Good)normally written on dead equipment destine for the repair bench, or the trash. More polite conversation for NFG - Not Feeling Good, Not Functioning Good.

To describe a member of your crew: He is Fuckin' worthless, why the hell did the hire him. He's a fuckin' moron, he doesn't even know how to set up a tripod.

As an adverb, especially for live truck drivers: It's raining so hard I can't see where I'm ******* going! Also: This fuckin' sucks, race out here to get the story, and sit on my ass while they wait 'til after the break to put the story on the air.

There are many more, more than I can remember at this time.


And if SHIT can get added, I expect this one to be added too!

No, sorry.

**** is already refered to under SHIT. SHIT was added in humor
and any other expletives would be overkill and sour the glossary.

In other words the joke has been made, duplicating it would not be
funny or useful.

Please add "chroma key" a definition can be distilled from here:

http://visualeffects.net/effectsguide/tutorial/Compositing.html

And also please remove SHIT, it is not a video specific term and therefore has no business being in the glossary. Other words have been rejected for this very reason, so it should be rejected for the same reason.

That term is not a video one.

from a previous post

[jimmalenko]

Best, adj.

There is no best.

"Best" is a subjective term, normally based on opinion. That said, occasionally facts prove unequivocal best, but only very occasionally.

Do you mean "Best" as in "highest quality" ?
Perhaps "Best" as in "accept most source formats" ?
Maybe "Best" as in "easiest to use" ?
Or "Best" as in "fastest" ?

The best for you is the one that gives you the results you're trying to achieve.

Very good point, Jim, and I wish posters could understand this. I'm not sure I'm allowed to add to the glossary anymore and if I could I can't include this term as it is not a video one.

... and if I could I can't inlude this term as it is not a video one.

Personally I can't see any way that "highest quality", "accept most source formats", "easiest to use" or "fastest" could be anything BUT video-related terms ........ but you're the mod
