A vodcast, simply put, is a podcast with video content or video files created with the intent of sharing and downloading the video file to other computers or mobile devices. As technology continues to improve and become cheaper, this media format increases in popularity and availability.
==What is a Vodcast or Vidcast?==


==Vodcast Format==
A vodcast or vidcast, simply put, is a broadcast using video content or video files created with the intent of sharing and downloading the video file to other computers or mobile devices. As technology continues to improve and become cheaper, this media format increases in popularity and availability.  The legacy term "vidcast" has the same meaning. Vodcasts are useful for a variety of reasons, such as giving lectures, presentations or even essays. Vodcasts can either be a live recording for an audience to view immediately or it can be pre-recorded to save for a later time (Which can still technically be broadcasted live, just as a prerecording). There are several kinds of sites and applications on the Web such as Twitch or Youtube that assist with either live or pre-recorded Vodcasts.


==Etymology==
Vodcast is a portmanteau of Video iPod Broadcast, and extends from the portmanteau Podcast using the same roots. Vidcast, previously, was also a portmanteau of Video Broadcast.  However, the success of the podcast format lent itself to the video format.
==Vodcast vs Podcast==
The key difference between a vodcast and a [http://litmuse.mga.edu/litwiki/index.php/What_is_a_podcast%3F podcast] is the additional content that a vodcast brings to the table. While both do contain audio, a vodcast offers visual media such as video or photos to accompany the audio provided.
----
==Vodcast Structure==
Just like other videos and films, the typical linear structure is as follows:
* Titles
* Intro
* Topic(s)
** Topic Supports
* Summary / Recap
* Conclusion
* Outro
* Credits / End Titles
----
==Uses for Vodcasts==
The uses for vodcasts are nearly as varied as the people who make them. Some are for entertainment, others are for education, news, instructions, and more. The list is extensive, but it boils down to one thing: communication through video, usually with an audio component.
====Recorded Video====
This is the most common form of vodcasting. This is the style that is seen on sites such as YouTube and Vimeo, and is the output from many camcorders, cellphones, and tablets.  Videos may be vodcast without further editing as raw footage, or may undergo editing using software such as non-linear editors, or NLEs.<ref>http://www.dummies.com/how-to/content/comparing-video-editing-methods.html</ref>
====Streaming====
A form of vodcasting that is gaining in popularity. Streaming is done live, as opposed to being recorded, and works much like live television programs. Users stream their video to certain web-based video platforms, like [http://www.justin.tv/ Justin.tv] or [http://www.twitch.tv/ Twitch] where viewers can watch it live and interact with the streamer via text-based comments.<ref>http://www.justin.tv/</ref><ref>http://www.twitch.tv/</ref> Two popular pieces of software that are designed for streaming are [http://obsproject.com/index Open Broadcaster Software] and [https://www.xsplit.com/ XSplit].
====Game Capture====
A popular form of vodcast these days involves the capture of video game footage with the player's audio. There are various forms of software and hardware that specialize in this form of capture. Software: [http://exkode.com/dxtory-features-en.html Dxtory] and [http://www.fraps.com/ Fraps].<ref>http://exkode.com/dxtory-features-en.html</ref><ref>http://www.fraps.com/</ref> hardware: [http://gamerzone.avermedia.com/ AverMedia] and [http://www.hauppauge.com/site/products/data_hdpvr2-gaming.html Hauppauge] <ref>http://gamerzone.avermedia.com/</ref><ref>http://www.hauppauge.com/site/products/data_hdpvr2-gaming.html</ref>. Dxtory and Fraps capture footage in a lossless format and at varying frame rates. It is recommended that a separate hard disk be used in conjunction with the software, as the recording can be very resource intensive and the file outputs are typically quite large. [[File:gamerPortable.jpg|right|thumb|Live Gamer Portable]]
=====AverMedia=====
AverMedia is one of the most commonly used hardwares for game capture. They offer various solutions with their products such as the [http://gamerzone.avermedia.com/game_capture/live_gamer_portable Live Gamer Portable] along with stationary options such as the [http://gamerzone.avermedia.com/game_capture/extremecap_u3 ExtremeCap U3]. These options provide outlets for users to create content for a vodcast to be live streamed or saved for a later point in time.


==Recording==
==Recording==
A vodcast can be recorded in many different ways. Regardless of the method used, however, various types of equipment and software are typically needed.

===Equipment===
===Hardware===
At the least, some method of video and audio capture is required to produce a vodcast. This could be done using a handheld video recorder or a webcam and microphone. The decision of which to use is important as they will both have different software options available to them.

====Camcorders====
====Camcorders====
Camcorders are handheld electronic devices that specialize in recording video. As one of the more expensive pieces of equipment, the camcorders do provide some of the highest potential quality for video capture, as well as audio capture with internal microphones or attachments. Camcorders can be bought for a little under US$200 and up into the thousands of dollars. Camcorders often also require batteries, memory cards (or disks), as well as more optional pieces of equipment like tripods that can add additional costs. It should be noted that one of the advantages of a camcorder is their ease of use in many different environments where computers with webcams may be more cumbersome or impractical.

It should be noted that one of the advantages of a camcorder is their ease of use in many different environments where computers with webcams may be more cumbersome or impractical. Transfer of data between the camcorder and computer may be a bit more cumbersome than a webcam, but there are a few different ways to go about doing it: via firewire port and cable, through an analog video capture card, or by USB.<ref>http://www.arcsoft.com/topics/camcorder/connect-camcorder-to-computer.html</ref>


======Examples======
======Examples======
Those interested in camcorders can find a range of devices like the [http://www.amazon.com/Sony-HDR-CX190-Definition-Handycam-Camcorder/dp/B006K551HQ/ref=sr_1_3?s=photo&ie=UTF8&qid=1384438248&sr=1-3 Sony HDR CX190] or the [http://www.amazon.com/Kodak-PlaySport-Waterproof-Pocket-Camera/dp/B004FLL5BI/ref=sr_1_9?s=photo&ie=UTF8&qid=1384438248&sr=1-9 Kodak PlaySport] which vary in size, shape and features -- such as being waterproof.

====Webcams====
====Webcams====
Webcams are video capture devices that are used in conjunction with a computer that often provides the webcam with power and a hard disk to save any recorded video onto. The cheapest video capture option of the two presented here, webcams can be purchased for under US$20. Many webcams offer high-definition recording (720p+) and have built-in microphones to record audio. These days many laptops will come with integrated webcams, allowing the owner to start vodcasting or doing video calls nearly immediately. While being very affordable, they do have the disadvantages of not being as versatile in their potential recording environments or not being quite as high quality as camcorders.

======Examples======
======Examples======
Those interested in using a webcam can find a wide variety of products in an equally wide range of prices, like the [http://www.amazon.com/Logitech-960-000585-HD-Webcam-C310/dp/B003LVZO8S/ref=sr_1_1?s=pc&ie=UTF8&qid=1384439418&sr=1-1&keywords=webcam Logitech HD Webcam 310] or the [http://www.amazon.com/Logitech-Webcam-Widescreen-Calling-Recording/dp/B006JH8T3S/ref=sr_1_3?s=pc&ie=UTF8&qid=1384439796&sr=1-3&keywords=webcam Logitech HD Pro Webcam C920]. The feature list tends to be a bit smaller than that of camcorders, but video quality can differ greatly.

The feature list tends to be a bit smaller than that of camcorders, but video quality can differ greatly.
====Cell Phones====
Creating a vodcast can be as simple as creating a video on your phone then sharing it on a video sharing site or streaming it live. All you need is a cellphone with a video camera and a microphone. Most new phones come standard with those two features. It should be noted that this is a very basic form of vodcasting and while it may be fairly efficient, quality issues can arise with the audio or video. There is a multitude of mobile applications you can download that will support mobile vodcasting.<ref>https://sites.google.com/site/digitalbackpack2012/mobile/mobile-podcasting-and-vodcasting</ref>


====Microphones====
====Microphones====
While many webcams do have integrated microphones, you may wish to purchase a separate microphone in order to increase the quality of the audio being recorded. Microphones tend to come in two different varieties: headsets and stand alone.
While many webcams do have integrated microphones, you may wish to purchase a separate microphone in order to increase the quality of the audio being recorded. Microphones tend to come in two different form factors: headsets and stand alone. Microphones are grouped into how they pick up sound. The most common are unidirectional.  Unidirectional picks up sound from one or more small, focused areas whereas the uncommon omnidirectional picks up sound from nearly every direction.<ref>http://www.performing-musician.com/pm/apr08/articles/technotes.htm</ref><ref>http://www.performing-musician.com/pm/may08/articles/technotes.htm</ref><ref>http://www.performing-musician.com/pm/jun08/articles/technotes.htm</ref>
[[File:Razer-kraken-pro-1-800x800-green-store-latest_store_gallery.png|left|thumb|Headset]]
[[File:SennMicrophone.jpg|left|thumb|Unidirectional microphone]]
 
Microphone sensitivity, or gain, is measured in dB, or decibels.  Other specifications that may matter are SPL, or Sound Pressure Level and THD, or Total Harmonic Distortion.<ref>http://www.learningaboutelectronics.com/Articles/What-is-the-sensitivity-rating-of-a-microphone</ref><ref>http://www.dpamicrophones.com/en/Mic-University/Technology-Guide/How-to-read-microphone-specifications.aspx</ref>


=====Headsets=====
=====Headsets=====
This type of microphone is usually attached to a pair of headphones and worn on the users head, allowing the microphone to be fixed a short distance from the speaker's mouth. The price of headsets varies greatly, though they are often very affordable. The audio quality, like the price, also varies greatly with the more expensive headsets providing clearer audio. Also of note are the two types of connectors used by headsets to connect to computers: USB and 3.5mm. There is typically not much difference between these two, unless a separate sound card is being used (which will typically warrant using 3.5mm).

Also of note are the two types of connectors used by headsets to connect to computers: USB and 3.5mm. There is typically not much difference between these two, unless a separate sound card is being used. However, the USB versions do require drivers which may not be available for the operating system on which it is used.  The mini-jack 3.5mm will work on every operating system as well as most tablets and smartphones with a line-in or microphone port.


======Examples======
Those looking for headsets will likely spend a decent bit of time sorting through the options available. A headset like the [http://www.amazon.com/Plantronics-Audio-478-Stereo-Headset/dp/B005VAORH6/ref=sr_1_4?s=electronics&ie=UTF8&qid=1384443137&sr=1-4&keywords=headset Plantronics Audio 478] is on the cheaper end and uses a USB connection, while the [http://www.amazon.com/Logitech-G230-Stereo-Gaming-Headset/dp/B00BFOEY4I/ref=sr_1_5?s=electronics&ie=UTF8&qid=1384443583&sr=1-5&keywords=headset Logitech G230] uses 3.5mm and is a bit more expensive. Different headsets also include different features, like in-line sound controls, noise cancelling, and folding or removable mics, among others.

Different headsets also include different features, like in-line sound controls, noise cancelling, and folding or removable mics, among others.


=====Stand Alone Microphones=====
=====Stand Alone Microphones=====
These microphones are, as the heading implies, by themselves and tend to focus on having higher audio quality. These are the microphones that people who tend to do a lot of podcasting, vodcasting, or other recording-based activity will favor. While there is  a wide range of prices and qualities available, they do tend to be a bit higher in both than headsets, though lacking the built-in speakers and wear-ability of the headsets. Microphones also have various means of connecting to a computer or other audio equipment, but, for the purposes of general vodcasting, a USB connection will most likely be used. One feature to look out for when purchasing a microphone is a cardioid polar pattern which, basically, just means that the microphone picks up noise coming from the front and not from the sides or back (or not as much). This helps create a cleaner audio sample, especially if the recording environment is a bit noisy.

Those interested in a stand alone microphone will find a variety of shapes and sizes, qualities and prices to choose from. For a more traditional and affordable approach, there is the [http://www.amazon.com/Audio-Technica-ATR2100-USB-Cardioid-Dynamic-Microphone/dp/B004QJOZS4/ref=sr_1_1?s=electronics&ie=UTF8&qid=1384443863&sr=1-1&keywords=atr-2100 Audio-Technica ATR2100] that uses USB or XLR connections.<ref>http://www.audio-technica.com/cms/wired_mics/b8dd84773f83092c/</ref> And for something a bit different, and a bit more expensive, there is the [http://www.amazon.com/Blue-Microphones-Snowball-Microphone-Aluminum/dp/B002OO333Q/ref=sr_1_24?s=electronics&ie=UTF8&qid=1384443826&sr=1-24&keywords=microphone Blue Microphones Snowball] that is also USB based.<ref>http://bluemic.com/snowball/</ref> Both of the example microphones do come with their own stands and USB cables, though it is important to note that this may not always be the case.
 
----
 
==Collaborative Video==
Vodcasting does not have to be a solo experience. Using such services as [http://www.skype.com/en/ Skype] or [https://plus.google.com/ Google+ Hangouts]<ref>http://www.google.com/+/learnmore/hangouts/index.html</ref> a group can create a vodcast together remotely, over the internet. In the case of Google+ Hangouts', the Hangout can be recorded automatically without the need for further editing or software. Skype, on the other hand, does require a separate program like [http://www.evaer.com/ Evaer] to record the video and audio of the Skype call, which can then be edited in a different program.<ref>http://www.evaer.com/</ref>
 
====Google+ Hangouts====
The video chat service from Google, Google+ Hangouts, offers a unique suite of features and apps that help facilitate and enhance the vodcast experience, especially when in a group. The service allows the operator of the Hangout to select individual video feeds, livestream the Hangout via Hangouts On Air, open a Q&A that allows watchers to submit questions that the operator can choose to have the group answer or not, and immediate upload of the Hangout to YouTube after the broadcast has ended.<ref>http://www.google.com/+/learnmore/hangouts/onair.html</ref> Hangouts also offer features to the individual users of the Hangout, like the Lower Third bar that acts as a nameplate to help easily identify the participants.<ref>http://www.google.com/+/learnmore/hangouts/index.html</ref> Another cool feature of Google Hangouts is the ability to share files with the other viewers. When the files are shared or opened via [https://drive.google.com/#my-drive‎ Google Docs] it can then be live streamed to all viewers.
 
====GoToMeeting====
GoToMeeting is an emerging way of creating a live Vodcast. Like Skype or Google Hangouts, multiple people can join in, and live content can be shared with the viewers. This can be especially useful in an online classroom setting. [http://www.citrix.com/ Citrix], the host of GoToMeeting just recently introduced a free version with up to three viewers.  However, there is a [http://www.gotomeeting.com/online/meeting/ pricing plan] that allows for up to 25 or 100 viewers.<ref>http://www.gotomeeting.com/online/</ref>
 
----
 
==Software==
Software is needed for the capturing, editing, transcoding or converting, and playback of the video and audio.  The five primary operating systems, Windows; OSX; Linux; Android; and iOS, each have a number of open-source and proprietary softwares for each of these operations.
 
The capture, or recording, software determines the initial format of the video. Using a webcam often has its own software to save the video in a predetermined format and size to the local harddrive, and usually has the ability to upload the video to a service provider such as YouTube or create a stand-alone video for uploading to a web server or even on physical media such as DVD or CD.
 
====Webcam Recording Software====
Most webcams come with their own software on CDs that is installed alongside the drivers. But there are other options available. For Windows users there is [http://windows.microsoft.com/en-us/windows-live/movie-maker#t1=overview Windows Movie Maker] that allows the capture of webcam footage and some general editing -- all for free. Windows users can also use [http://www.nchsoftware.com/capture/ Debut Video Capture Software] from NCH Software for free, provided the video is used non-commercially. Lastly, Mac users can capture webcam footage using [http://www.apple.com/quicktime/ Apple's QuickTime Player].<ref>http://windows.microsoft.com/en-us/windows-live/movie-maker#t1=overview</ref><ref>http://www.nchsoftware.com/capture/</ref><ref>http://www.apple.com/quicktime/</ref>
 
====Screencast / Desktop Recording====
=====CamStudio=====
CamStudio is an open-source software for recording a desktop screencast.<ref>http://camstudio.org/</ref>  Resulting videos are saved in AVI format, and CamStudio offers export to a stand-alone SWF Flash file.
 
====Camtasia Studio 8====
Camtasia is desktop/screen capture software that helps create and combine a variety of video content that is used to make vodcasts. Camtasia is able to live capture what is currently open on your screen and then make that content ready for editing after recording is completed.  Various effects such as zoom, text, shapes, and drawings can be added in the video process. Audio files can be imported from software such as Audacity to overlay the video content. However, this is not totally necessary if you are confident in your audio coming from the recording in Camtasia. Consequently, due to Camtasia being only editing software, it is not capable of live streaming and the user can only make pre-recorded material.<ref>http://www.techsmith.com/camtasia.html</ref>
 
====LiveStream====
LiveStream is a free streaming software option that can directly stream from any device that has is capable of audio and video ouput. <ref>http://new.livestream.com/broadcast</ref>


======Examples======
====Stupeflix====
Those interested in a stand alone microphone will find a variety of shapes and sizes, qualities and prices to choose from. For a more traditional and affordable approach, there is the [http://www.amazon.com/Audio-Technica-ATR2100-USB-Cardioid-Dynamic-Microphone/dp/B004QJOZS4/ref=sr_1_1?s=electronics&ie=UTF8&qid=1384443863&sr=1-1&keywords=atr-2100 Audio-Technica ATR2100] that uses USB or XLR connections. And for something a bit different, and a bit more expensive, there is the [http://www.amazon.com/Blue-Microphones-Snowball-Microphone-Aluminum/dp/B002OO333Q/ref=sr_1_24?s=electronics&ie=UTF8&qid=1384443826&sr=1-24&keywords=microphone Blue Microphones Snowball] that is also USB based. Both of the example microphones do come with their own stands and USB cables, though it is important to note that this may not always be the case.  
Stupeflix is a website that has software set up for you to combine audio, photos, and video to create a vodcast. There is a couple free options and there is also several options that have a minimal fee to use. <ref>http://studio.stupeflix.com/en/</ref>
 
====Codecs====
Codec is a portmanteau word created from encode-decode. A codec encodes and decodes data to a particular type or format.  In multimedia, codecs are responsible for software being able to create, play, and transcode video and audio.<ref>http://windows.microsoft.com/en-us/windows/codecs-frequently-asked-questions#codecs-frequently-asked-questions=windows-7</ref>
 
There are numerous codecs available. For example, the screen recording software CamStudio offers an open-source lossless codec.  Each of the formats listed on this page have corresponding codecs.
 
====Transcoding / Converter Software====
Transcoding, or Converting, is taking a file of one format and creating a duplicate file in another format.  The terms are, for all practical purposes, interchangeable.
 
Many converters, including some famous and infamous commercial software, are front-ends for FFMPEG.<ref>http://www.ffmpeg.org/projects.html</ref>
 
=====FFMPEG=====
FFMPEG is a multi-functional tool.  It is used for capturing, recording, processing, transcoding and converting, and editing, and is the backbone to dozens of multimedia applications, from recording, to transcoding, to editing.  The software in which FFMPEG is found ranges from free to hundreds, and even thousands, of dollars.<ref>http://www.ffmpeg.org/projects.html</ref>
 
FFMPEG is open-source and can be downloaded from ffmpeg.org<ref>http://www.ffmpeg.org/</ref>
 
=====Handbrake=====
HandBrake is a free, open-source project and software that transcodes / converts video files from one format to another. It is available for Windows, Mac, and Linux.<ref>http://handbrake.fr/</ref>
 
=====Miro Video Converter=====
Miro Video Converter is a free, open-source video converter software available for Windows and Mac operating systems. It is known as a 'front-end' for FFMPEG.  In other words, it is a graphical user interface designed to create commands which are given to FFMPEG which does the actual conversion work.<ref>http://www.mirovideoconverter.com/</ref>
 
=====H.264 Software=====
x264 codec and software for H.264<ref>http://www.videolan.org/developers/x264.html</ref> [[File:audacity.jpg|right|thumb|Audacity Work Space]]
 
=====Audacity=====
Audacity is a  fairly common, free software application for sound and audio files. The user is able to record and edit an audio file(assuming there is an input device to record the audio). Users are also able to convert the audio in a long list of possible file types such as .wav and .mp3 . <ref>[http://audacity.sourceforge.net/</ref>

====Video Editing====
[[File:Avidstudio.jpg|right|thumb|Avid Studio promo showing NLE interface]]
With the exception of the Google+ Hangouts, most video will require some editing before it can be published. To aid in this endeavor are a variety of programs that can fully edit a video, like [http://www.sonycreativesoftware.com/moviestudiope Sony's Movie Studio], [http://www.adobe.com/products/premiere-elements.html Adobe Premier Elements], [http://www.apple.com/finalcutpro/ Apple's Final Cut Pro X], and [http://www.arcsoft.com/showbiz/ ArcSoft Showbiz] which accompanies the Hauppauge game capture hardware. Each of these, except for Apple's Final Cut Pro X, are known as 'non-linear editors', or NLEs.<ref>http://www.dummies.com/how-to/content/comparing-video-editing-methods.html</ref> If you feel your video does not need the full editing treatment and you just wish to compress it down for uploading, there are free programs around to help with that, like [http://handbrake.fr/ Handbrake] that can convert and compress a video so it will be accepted by the various internet video publishing platforms, like YouTube.<ref>http://handbrake.fr/</ref>
 
===Size===
Aspect Ratio is an important criterion to consider.  There are two primary ratios, 4:3 and 16:9.  The current standard is 16:9, or 'widescreen'.<ref>http://documentation.apple.com/en/dvdstudiopro/usermanual/chapter_4_section_4.html</ref>  There are other less-used ratios, primarily used in film.<ref>http://www.red.com/learn/red-101/video-aspect-ratios</ref>
 
The larger the video, the more bandwidth (internet speed) needed for downloading and streaming the video, and the longer it takes to upload.

====HD / Widescreen====
=====Aspect Ratio 16:9=====
* Modern Television
The current standard for television and High Definition video created by consumer-grade cameras and software.<ref>http://www.projectorcentral.com/build_home_theater_screen_aspect_ratio.htm</ref>


===Software===
Popular sizes:<ref>http://pacoup.com/2011/06/12/list-of-true-169-resolutions/</ref>
The software needed for recording will most likely revolve around the formatting of the recorded video. However, if you decide to use a webcam you will also need software to capture the video to your computer's hard disk. Thankfully, most webcams come with their own software that can handle this.

====Capturing Group Video====
====Standard Definition====
Vodcasting does not have to be a solo experience. Using such services as [http://www.skype.com/en/ Skype] or [https://plus.google.com/ Google+ Hangouts] a group can create a vodcast together remotely, over the internet. In the case of Google+ Hangouts', the Hangout can be recorded automatically without the need for further editing or software. Skype, on the other hand, does require a separate program like [http://www.evaer.com/ Evaer] to record the video and audio of the Skype call, which can then be edited in a different program.
=====Aspect Ratio 4:3=====
* Legacy Television
This is the size, or ratio, of 20th century televisions.<ref>http://filmmakeriq.com/lessons/the-changing-shape-of-cinema-the-history-of-aspect-ratio/</ref>  The aspect ratio of 4:3 is slightly rectangular but much more box-shaped than widescreen formats. Many older camcorders and webcams output to the 4:3 ratio.

==Publishing==
==Publishing==
There are many ways to publish your vodcast, including services such as YouTube and Vimeo. Other options include using your own web hosting and video player such as JWPlayer.
There are many ways to publish a vodcast, including services such as YouTube and Vimeo. Other options include using your own web hosting and video player such as JWPlayer.
===Internet===
===Internet===
One of the first steps in publishing a video is getting it onto the internet. If running a server and doing self-hosting is not your thing, there are several different websites that will host your videos for free, or by having advertising run alongside them. Two popular examples of this type of website are YouTube and Vimeo.
====YouTube====
====YouTube====
Perhaps one of the best known video-sharing websites, [http://www.youtube.com/ YouTube] is currently owned by Google and allows users to upload their videos to the site for free. Users that verify their accounts or are eligible for YouTube Partnerships<ref>https://www.youtube.com/yt/creators/creator-benefits.html</ref> can gain access to additional features, such as custom thumbnails.<ref>http://www.youtube.com/</ref>
====Vimeo====
====Vimeo====
[https://vimeo.com/ Vimeo] is another popular video-sharing service, with a bit more focus towards filmmakers. One of the primary differences between Vimeo and YouTube is that Vimeo has a more stringent list of unacceptable content. Vimeo also offers a paid-for service called Vimeo Plus<ref>http://vimeo.com/plus</ref> that enables the user to have more control over their videos and allows more HD uploads. And, for the serious, professional filmmakers, there is Vimeo PRO<ref>http://vimeo.com/pro</ref> that adds even more features and a yearly cost of US$200.
=====Vodcasting for Monetary Gain=====
In this ever changing technological age, new ways to make money will continue to arise. Vodcasts are no exception and users have began to take advantage of this. When users host live or pre-recorded vodcasts across mediums such at Twitch, Vimeo, and Youtube there is opportunity for monetary gain. Reaching a certain number of viewers, subscribers, shares, and traffic will open up opportunities for sponsorship and advertisement that can result in a user making a profit for their work.
===Self Publishing===
===Self Publishing===
====FlowPlayer====
FlowPlayer is a free, customizable, feature-rich player with support for HTML5 or Flash, depending on version.<ref>http://flowplayer.org/</ref> FlowPlayer also offers brandable player licenses for a fee.<ref>http://flowplayer.org/download/</ref>
====HTML5====
HTML5 includes standards for audio<ref>http://www.w3.org/wiki/HTML/Elements/audio</ref> and video<ref>http://www.w3.org/wiki/HTML/Elements/video</ref> support, as well as in-browser video conferencing - strikingly similar to Skype - called [http://www.webrtc.org/ WebRTC].<ref>http://www.webrtc.org/</ref>
HTML5 is poised to replace Flash as the standard, literally, for audio and video presentation.<ref>http://www.zdnet.com/blog/networking/flash-is-dead-long-live-html5/1633</ref> 85% of all browsers and devices currently in use already support HTML5.<ref>http://www.jwplayer.com/html5/</ref>
=====Video Player Comparison Table=====
The folks at [http://praegnanz.de/ praegnanz.de] made a great [http://praegnanz.de/html5video/ HTML5 video player comparison table] which includes demonstrations of each listed player.<ref>http://praegnanz.de/html5video/</ref>
====JWPlayer====
====JWPlayer====
JWPlayer was one of the first, and currently one of the most popular, video players designed for use in private websites.  It is among the first to adopt the HTML5 standard.<ref>http://www.longtailvideo.com/support/jw-player/28832/about-jw-player</ref>


JWPlayer is no longer free for commercial use, nor does it have a straight licensing fee.  Now it is a 'rental' on a yearly basis.<ref>http://www.jwplayer.com/pricing/</ref>
====MediaElement.js====
MediaElement.js is a free player with support for H.264/MP4 AVC, WebM, FLV, MP3, WMV, and YouTube.<ref>http://mediaelementjs.com/</ref> It also is the core support for audio and video in WordPress.<ref>http://make.wordpress.org/core/2013/04/08/audio-video-support-in-core/</ref>
====VIDEO.JS====
VIDEO.JS is a free, open-source, skinnable, and customizable player that supports HTML5.<ref>http://www.videojs.com/</ref>
====WordPress====
Starting with version 3.6 WordPress offers built-in audio and video support using MediaElement.js.<ref>http://make.wordpress.org/core/2013/04/08/audio-video-support-in-core/</ref>
