Digital video, which has many formats, is a very beneficial tool. Businesses can harness its unattended power for Internet marketing (the process of promoting, selling and distributing a product or service 24 hours a day, 7 days a week on the Internet). There is no better way to sell in a global marketplace that purchases 24 hours a day than with a well-designed website that includes this beneficial tool. He is also involved in many litigation cases and quickly makes his way through courts around the world.
In the following paragraphs, my goal is to help you understand digital video in regards to CCTV systems and their many formats.
In its simplest terms, digital video can be defined as video that has been recorded using a software program and stored digitally on a computer. A CCTV system is a computer. That digitized information can be controlled from a computer and displayed directly on a computer monitor.
All current digital video file formats, listed below, are based on PCM or pulse code modulation. PCM is a digital representation of an analog signal where the magnitude of the signal is regularly sampled at uniform intervals, then quantized to a series of symbols in numerical form (usually based on binary code).
Here is a short catalog of digital video file types to give you a better understanding of how they are used.
CCIR 601 (or RE 601) is a file that is used for broadcast television stations due to the conversion of analog and digital television. This digital video file format converts and encodes interlaced analog video signals into digital video.
In the old days, television commercials were distributed first in analog format, then on digital tape. Today, television commercials can be distributed over wireless networks electronically using digital video technology.
Services like SpotMixer allow companies to create their own commercials online and distribute them across a large number of media, including television and the Internet.
MPEG-4 is good for online distribution of large videos and videos recorded on flash memory. This is a digital format that is used for iPods with video and for uploading to YouTube and other social networks, but read on.
MPEG-2 (used for DVD) is a digital file format used to create DVDs. An MPEG-2 digital video file recorded on a DVD will play video on a DVD player and computer, as long as the computer is capable of playing DVDs. Some computers with older DVD technology will have difficulty reading DVDs that have been recorded with newer technology.
MPEG-1 is used for video CDs and was the first digital video format to be massively marketed. It is rarely used today, but it does appear occasionally. Many DVD players will play MPEG-1, but not all can read this digital file format.
H.261 was the first truly practical digital video coding standard. In fact, all subsequent international encodings such as MPEG-1, H.262, MPEG-2, H.263, MPEG-4, and H.264 (MPEG-4 Part 10) have been closely based on the H.261 design, which is now rarely used.
H.263 is a video codec standard originally designed as a low bit rate compressed format for video conferencing. Since then, H.263 has found many applications on the Internet: much of Flash Video content (as used on sites like YouTube, Google Video, MySpace, etc.) is encoded in this format.
The original version of Real Video (which I recommend you avoid) was based on H.263 until the release of Real Video 8. In other words, I am telling you about H.263 so you can see the legacy.
H.264, also known as MPEG-4 Part 10 or as AVC, is the next enhanced codec developed for sharing digital video on the Internet. H.264 provides a significant improvement in capacity beyond H.263. The H.263 standard is now primarily considered a legacy design (although this is a recent development).
Most new video conferencing products now include H.264 capabilities, as well as H.263 and H.261. Primeau Productions uses H 264 digital video in Quicktime format to send to webmasters for use in Flash video encoding on customer websites.
Here’s the bottom line: The files above are created using computers, including CCTV systems, and can be viewed with video editing software and digital video file converters.
H.264 technology is an excellent starting file format for creating Flash videos. Video editing software programs can output various sizes of H.264 and can be used in various ways:
1. A source digital video file to create a Flash video for your website
2. A digital video file that can be sent by email
3. A digital video file that can be uploaded to social networks such as YouTube, Yahoo, and Viemo.
4. To view a converted CCTV video codec in the cut
Flash video is a web-based digital video player. It is cross-platform, so I recommend using it for the delivery of digital video content on your website.
Although many editing programs such as Final Cut, Vegas, and Premiere are capable of exporting finished video productions in Flash video (.FLV), creating a full Flash video involves more than just the video file.
When a digital video file is created as H.264 (encoded with specs of less than 10 minutes and 1Gig) and uploaded to YouTube, Yahoo, MetaCafe, and Viemo, the H.264 file is converted to Flash video during the process of uploading. load.
Many services that publish PR videos on their websites now only accept Flash Video (.FLV) files. HTML 5 is out and about taking over Flash, but it still has a long way to go.
If you are interested in publishing a Flash video on your website, the following are the components you need in addition to the .FLV video file:
1. The .html part: the HTML web page that Flash Player loads.
2. The .swf part: the compiled flash file for the web (contains the flash video player)
3. The .flv part: the actual video file for the flash player.
4.ac_runactivecontent.js: the javascript file that loads the player in browsers
A non-video production based software program made by Adobe called Flash is used to create graphics and videos for websites.
Flash Video is a file format used to deliver video over the Internet using Adobe Flash Player. The format has quickly established itself as the format of choice for embedded videos on the web. Notable users of the Flash Video format include YouTube, Google Video, Yahoo, MetaCafe, Viemo, Reuters.com, and many other news providers.
Flash Video can be viewed on most operating systems, through the widely available Adobe Flash Player.
Lastly, standardized Theora is still under development and not used very often, but it’s still worth mentioning to complete your understanding of the various file formats available today.
An important conclusion is an understanding of file formats and the many uses of digital video.
