Today, video stats account for 80 percent of global consumer internet traffic.
Online streaming has become an integral part of our daily lives, transforming the way we consume video content. Whether we’re binge-watching our favorite series, catching up on the latest news, or indulging in breathtaking 4K videos, the quality of the streaming experience matters more than ever before. Behind the seamless playback lies a crucial factor – video codecs.
Video codecs play a pivotal role in compressing and decompressing video files, ensuring efficient data transmission over the internet while maintaining visual fidelity. Among the leading contenders in the quest for optimal streaming quality are AV1, HEVC (H.265), and VP9. These codecs have been shaping the future of online video streaming, vying for the top spot as the ultimate solution.
And as per survey predictions, by 2021 video will be responsible for an unprecedented 85% of total internet consumption worldwide.
In order to handle this intense delivery load and at the same time, distribute videos seamlessly across the internet, the video streaming companies have started adopting advanced video compression tools, also known as Video Codecs. Using high-level coding formats, the service providers are unblemishedly condensing the large video files for smooth delivery across multiple online channels.
Fact you must know
“Streaming and Chilling would never have been coined together without the invention of video codecs. It’s like, codecs are the reason, viewers comfortably stream their favorite videos even with limited bandwidth.”
No doubt, Codecs play a key role in the distribution of digital videos online.
However, choosing the right video codec involves a lot of confusion, as the options are available in plenty. But don’t worry, here in this blog, our primary goal is to educate readers about video codecs and discuss the best-quality codecs for video streaming.
What is a Video Codec?
A video codec is a ready-made software program that is used for compressing and decompressing video streams. Mainly content aggregators, distributors, and streaming service owners integrate video codec in their applications to tightly compress the high-definition videos into a more manageable size, ensuring seamless content storage as well as delivery.
The best thing about using video codec is, no compromise with the video quality during the compression and decompression process. It’s simple, codecs are in charge of interpreting all the data and content stored in the video files and controlling how the video is streamed on the user’s screen.
Presently, AVC is the most commonly used video codec because of it’s open-sourced and royalty-free configurations.
Role of codec in Video streaming
Viewers love streaming videos online, especially when there is no buffering or lag issues. They simply prefer to stream high-definition videos in maximum resolution.
Now considering the above fact technically, high-quality video streams involve high bit-rate and more data storage. Such files require a lot of processing power to encode and a high-speed internet connection to download for playback.
Fact you must know
“When a file streams at thirty-frames per second (high-quality video file), the requirement for storage space and bandwidth balloons quickly. If the streaming platform, delivering the video, fails to meet the requirements, then there are high chances, the end-users will experience trouble in watching the videos online.”
Well, here comes the need for video codecs, as those are exclusively designed to deal with such problems.
At the core, codecs are advanced video compression tools that work on encoding and decoding algorithms. In order to deliver uninterrupted video streams on user’s screen, codecs eliminate out certain un-necessary data from the videos and reduce the file size without hampering its overall quality.
Once compressed, all the components of video are wrapped into a specific file format, termed as Containers. Generally, the containers store video codecs, audio codecs, closed captioning, and other important metadata, supporting multiple file formats such as MKV, MP4, WMV, AVI, MOV, QT, and AVCHD.
For more details on video containers, read our blog How to Choose the Best Video Container Format for Live Streaming.
Depending on the other video codec that is installed in the user’s device, the container then determines which programs are compatible for the stream and accordingly distributes components for decompression. Further, the video codec at the user-end decodes the file and ensures seamless streaming.
So, this is how a video codec acts both at the source end (during encoding) to compress the video file and before playback (during decoding) to decompress it.
Now though you are clear about what is a video codec and how it works, let’s have a look at the most efficient & performance oriented video codecs in the OTT space.
Most Commonly Used Video Codecs
H.264 or AVC (Advanced Video Coding) is a widely supported legacy codec that enables playback on both out-dated and new devices.
