Video encoding is the process of converting digital video files from one standard digital video format into another. The encoding process transforms the video and audio data in the file and then does compression according to the specifications of the encoding standard chosen.
Techopedia explains Video Encoding Video encoding is the process of changing a digital video's format from one standard into another generally for the purpose of compatibility.
This is because digital video can exist in different formats with different variables such as containers like. Video encoding is therefore simply the process of preparing a video for output, which greatly varies depending on the intent and use. Share this:. Related Terms. Related Articles.

Encoding, decoding, and transcoding are three core processes that underlie the speedy transfer of video files to a playable format for your viewers around the world. Encoding is the process of compressing large video files for easier uploading to the internet.
Broadcasters use either a hardware or software video encoder for the task. At 60 frames-per-second, you'd need an upload speed of almost 3 Gigabits-per-second Gbps to send that p video to the internet. Fortunately, most cameras use a technique called chroma subsampling to reduce the amount of data needed to represent the image. This process can cut your p60 video to about 1.
Encoding is your answer for squeezing your video down to an even more manageable size for rapid transit across the information superhighway. The most common video codec for streaming is H. Using H. Recall that without compression, the raw video would require an upload speed of 3 Gbps— or Mbps.
What is Video Encoding? Codecs and Compression Techniques
HEVC is another video codec gaining traction in the streaming world; it promises higher quality video for the same bit rate, or a reduction in bit rate over an equivalent-quality H. If you're streaming from a video camera set up, you'll need either a software encoder or a hardware encoder— like the BoxCaster or BoxCaster Pro — to encode your video for transfer to the internet.
If you use a mobile device for video capture, your phone or tablet has a built-in encoder. You can take advantage of the powerful codec in your iOS device with our Broadcaster App. Once your video is encoded, it's ready for transfer across the internet to your viewers.
Reaching your viewers across the world requires a content delivery network CDN. Most live streaming platforms provide CDNs as a part of their service.
Once the compressed video reaches your viewers, it needs to be expanded back to its original size. That's where decoding comes in. Decoding is the opposite process of encoding. The action takes compressed video files and expands them back to their original form.Your question may be answered by sellers, manufacturers, or customers who purchased this item, who are all part of the Amazon community.

It also covers why certain artifacts, related to compression, might appear in your video. Video encoding is the process of compressing and potentially changing the format of video content, sometimes even changing an analog source to a digital one. In regards to compression, the goal is so that it consumes less space. Upon decompression for playback, an approximation of the original is created.
The more compression applied, the more data is thrown out and the worse the approximation looks versus the original.

Now there are two reasons why video encoding is important. The first, especially as it relates to streaming, is it makes it easier to transmit video over the Internet. This is because compression reduces the bandwidth required, while at the same time giving a quality experience. Without compression, raw video content would exclude many from being able to stream content over the Internet due to normal connection speeds not being adequate. The important aspect is bit rate, or the amount of data per second in the video.
For streaming, this will dictate if they can easily watch the content or if they will be stuck buffering the video. The second reason for video encoding is compatibility. In fact, sometimes content is already compressed to an adequate size but still needs to be encoded for compatibility, although this is often and more accurately described as transcoding.
Being compatible can relate to certain services or programs, which require certain encoding specifications. It can also include increasing compatibility for playback with audiences.
Video codecs are video compression standards done through software or hardware applications. Each codec is comprised of an encoder, to compress the video, and a decoder, to recreate an approximate of the video for playback.
The name codec actually comes from a merging of these two concepts into a single word: enCOder and DECoder. Example video codecs include H.Get Datasheet. Get a Demo. Close Get Pricing.

It was a little like driving in stop-and-go traffic during a heavy rain. On top of that, everything was choppy, pixilated and hard to see.
Streaming video and audio have come a long way since then.
According to Bridge Ratings57 million people listen to Internet radio every week. Inpeople watched more than a million streaming videos a day on YouTube [source: Reuters ].
People who missed an episode of shows like " Lost " or "Grey's Anatomy" could catch up on the entire thing online -- legally and for free. When someone talks to you, information travels toward you in the form of a sound wave.
Your ears and brain decode this information, allowing you to understand it. This is also what happens when you watch TV or listen to the radio.
Information travels to an electronic device in the form of a cable signala satellite signal or radio waves. The device decodes and displays the signal.
In streaming video and audio, the traveling information is a stream of data from a server. The decoder is a stand-alone player or a plugin that works as part of a Web browser.
The server, information stream and decoder work together to let people watch live or prerecorded broadcasts. In this article, we'll explore what it takes to create this stream of ones and zeros as well as how it differs from the data in a typical download.
We'll also take a look at how to make good streaming media files. If you have a connection to the Internet and you want to find streaming video and audio files, you shouldn't have to look far. Sound and video have become a common part of sites all over the Web, and the process of using these files is pretty intuitive.
You find something you want to watch or hear -- you click it, and it plays. Unless you're watching a live feed or a webcastyou can often pause, back up and move forward through the file, just like you could if you were watching a DVD or listening to a CD. But if you've never used streaming media, your computer may need a little help to decode and play the file.
You'll need a plugin for your Web browser or a stand-alone player. Most of the time, the Web page you've visited points you in the right direction. It prompts you to download a specific player or shows you a list of choices. These players decode and display data, and they usually retrieve information a little faster than they play it.For example, the FSD for 2015 is 2, and for 0.
The array represents the number of occurences for each digit from 1 to 9. Name of the outlier detection test. Currently only value available is grubbs. When name is grubbs, it returns Grubbs Result Object. An outlier present in the data. It is available only when at at least of one of the boolean values in significant is true.
Example: 128 description optional A description of the model up to 8192 characters long. Example: true name optional The name you want to give to the new model. Example: 10 randomize optional Setting this parameter to true will consider only a subset of the possible fields when choosing a split. Example: 16 tags optional A list of strings that help classify and index your model. Boosting attribute for the boosted tree.
All the information that you need to recreate or use the model on your own. Specifies the list of ids of the field that the model predicts. More concretely, it contains the training data distribution with key training, and the distribution for the actual prediction values of the tree with key predictions. Importance is the amount by which each field in the model reduces prediction error, normalized to be between zero and one. Default strategy followed by the model when it finds a missing value.
At prediction time you can opt for using proportional. A dictionary with an entry per field used by the model (not all the fields that were available in the dataset).
They follow the same structure as the fields attribute above except that the summary is not present. A Node Object, a tree-like recursive structure representing the model.
Method of choosing best attribute and split point for a given node. For classification models, a number between 0 and 1 that expresses how certain the model is of the prediction.
