Elise is a digital marketer and an SEO expert. Video technology has undergone massive evolution in the past couple of decades. This growth has come simultaneously with the development of the internet. While motion pictures—videos made of large collections of still photos—were fine in the age of VHS tapes and even DVDs, it made for excessively bulky files when videos became digital.

It became difficult to upload and share with more modern types of hardware. Video encoding was brought to life as a solution to aid in this technological transition. In the most basic sense of the term, video encoding is compressing video files so that they are not saved as individual images but as a fluid video. Imagine a basic flip-book.

Photos are put together in a way that seems to move when you flip through the page quickly. In the early days of digital video, video files were all RAW video.

This means that video files were a collection of still photos. For a video recorded at 30 frames per second, you had 30 photos per second of footage. As a result, video file sizes were massive.

The only sensible solution was to compress these videos, but the quality was lost through this process. Engineers developed video encoding which provided a way to compress these files without compromising the quality. It analyzes the content of a video to reduce the overall file size by determining which frames are essential and which can go. If two frames are basically identical, you can get rid of the data for one frame and replace it with a reference to the previous frame.

In this simple example, you can reduce your video file size by about 50 percent. All types of video compression use variations of this process to reduce file sizes. Video compression typically happens at the camera level. For example, smartphones, consumer-grade camcorders, and most professional camcorders record video in the H. This means that, as the camera is recording, the RAW images from the video sensor encode in real-time, typically using the H. This compressed—or encoded—video then records to the storage on the camera.

Different devices have different types of support for various codecs. Have you ever downloaded a video then tried to play it to find that playback failed? You might not have had software capable of playing back video encoded with that codec. However, encoding and transcoding are not one and the same. Transcoding is always encoding, but encoding is not always transcoding. There are a variety of reasons why you might want to transcode or encode a video:. The common purpose of all of these reasons is generally to create the best experience for viewers or to make the video content more easily accessible.

Dacast is a video hosting platform that is designed for advanced video hosting. The platform includes features such as an advanced bulk uploader and a Dropbox uploader. Video encoding comes with our online video platform. You simply have to indicate your preferred settings when uploading your video.

The software automatically transcodes your video into multiple different formats according to your indication. Here is a more detailed look at how the encoding process works with Dacast:. The first step in encoding your videos on the Dacast platform is to create an ingest recipe.

For context, an ingest recipe is a group of encoding presets at which the platform will encode and deliver your videos. Log into your online portal, and navigate to your encoding settings. When it takes you to the next screen, input a title at the top to name your recipe. Next, use the checklist to decide which renditions—or quality and size presets—you want to use for this ingest recipe.

Finally, check the box at the bottom if you want to use this as your default setting. Note that optimal visual quality p is best for HD video playback.

Please select one of the following configurations and ensure your encoder is set up with these exact encoder settings to help prevent issues:. You can create different ingest recipes for different initial video formats. For example, if you film most of your content at x resolution, 30 frames per second and recorded using H.

MOV container format, you can create an ingest recipe for these preferences. This recipe might transcode this video into three additional versions: one pixels wide, one pixels wide and one pixels wide. This will allow viewers to be served the optimal quality via adaptive bitrate streaming. You likely will have times where you want to record footage with different settings. You can create a second ingest recipe for this preference. When you want to upload videos in a different format, just select the preferred recipe and your content will be automatically transcoded into your chosen formats.

Mix and match video file types and resolutions, and the system will expertly encode your videos to the highest quality possible using your chosen ingest recipes. During this stage, you can choose to create audio-only versions of your video. In addition to a variety of video qualities, you can also choose to add watermarks and generate thumbnails.

The OVP platform also supports Dropbox upload. You can connect Dacast and your Dropbox account to set as many videos to upload as you desire. Once the Dropbox Uploader is active, a folder will appear for you in your Dropbox account where you can find all of your video files. Once they are there, the videos will automatically upload using your default ingest recipe. There is one common misconception that we need to clear up. Encoding can do a lot of things, but it cannot retroactively improve the quality of a video.

Attempting to encode the video into a larger resolution than you started with will only result in a very bad quality video. Of course, there are ways to upscale video to larger sizes. However, this is a complicated and intensive process.

When the cellular signal is good, video quality is high. The underlying technology behind adaptive streaming is transparent to you and your users. Dacast simply delivers the best version of your video—based on the versions created using your ingest recipe—to your viewer. In general, these represent a trade-off:.

Imagine that your internet connection is a tube. The faster your connection, the larger the tube. Low-speed Internet connections have narrower pipes. Those large files need to squeeze through them. As a result, you run the risk of subjecting your clients to stuttering and buffering streams. All else being equal—for example, the same codec—there are four main contributing factors that determine video file size in relation to quality.

These include:. There are seven common encoding challenges that broadcasters find themselves facing. Here are a few solutions that may help you navigate encoding roadblocks that you may encounter.

Video files tend to be larger files, so they require fast internet speed with great bandwidth to display the video properly. When the Internet connection is slow, the video starts stuttering and often displays in very poor quality. With Dacast, you can use the analytics feature to determine where most of your viewers live. Then, the software will match that information with average internet speeds to get a sense of the average connection speed of your customers. You can set your overall bit rate to match their download speed in order to achieve a reliable playback.

We recommend a short trial and error test to determine which settings to use. This will help you determine how low you can get the bit rate of a video while maintaining the appropriate quality. To conduct the test, you can start with a high frame width say px, which is p at the aspect ratio and a relatively low bit rate around kbps. See how the video looks when encoded with these settings. If you are not pleased with the image quality, try either lowering the frame width or increasing the bit rate.

Also, be sure to encode multiple versions of your video. Adaptive streaming will ensure viewers get the best quality they can stream smoothly. The more often your videos play and the higher their quality, the more bandwidth you will need. Every Dacast pricing plan comes with a particular bandwidth limit. You can use the same approach as in the previous question to reduce bitrates to the lowest acceptable level.

This will reduce your bandwidth consumption. If you really need to reduce file size to lower bandwidth consumption or serve users with slow internet connections, try reducing the bitrate.

This could have something to do with the frame rate of your video. Use a free tool such as MediaInfo to check the frame rate of your original file. If the frame rate of your video is unusual, you may discover the audio is out of sync after encoding.

In that case, we recommend you to try the Two-pass Encoding feature. This can solve many issues the encoder might have interpreting frame rates.


Video formats explained

If you read a two-page article, you would discover the differences. When the digital age dawned, everything went out the window. Suddenly there was a bewildering array of video formats —. Many work hours can be lost to footage in formats that render slowly or need to be transcoded. But fear not!

This document describes the media codec, container, and network protocol support provided by the Android platform. As an application developer, you can use any media codec that is available on any Android-powered device, including those provided by the Android platform and those that are device-specific. However, it is a best practice to use media encoding profiles that are device- agnostic. The tables below describe the media format support built into the Android platform. Codecs that are not guaranteed to be available on all Android platform versions are noted in parentheses, for example: Android 3.

Our mobile devices are faster, the way we watch videos on our TVs has changed, and the way we buy and store content is completely different from 20 years ago. We're in the middle of a home media revolution, where shelves of DVDs are being pushed into NAS boxes and discreetly hidden away. We're only in the infancy of this revolution, though. That means we've yet to find a definitive method, and there are as many good solutions as there are pitfalls. Codecs are the best example. If you've had anything to do with digitised video over the last 10 years, you'll know that video performance is dominated by the black art of manipulating these encoding and decoding programs. Finding the right one is a balancing act between the amount of processing that goes into creating the video file and the amount required to decode it.


Video Encoding: The Definitive Guide [Updated for 2020]

In the world of digital video production and distribution, few topics are more convoluted and confusing than choosing an appropriate video format. The reasons for this are both numerous and varied. First and foremost, not every video format is compatible with every digital platform when it comes to production and playback. This can create tremendous problems while attempting to input, output, upload, and download necessary files.
