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. | |||

==== | ==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==== | ====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]. | A form of vodcasting that is gaining in popularity.

==== | ====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.

=====AverMedia===== | |||
AverMedia is one of the most commonly used hardwares for game capture.

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

====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> | |||

[[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> | |||

=====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.
