H.264 video compression11/8/2023 H.264 or Advanced Video Coding is a video compression technique that is used widely to convert video to a format that takes up less space while transmitting or storing video files. The quest for better video streaming quality along with lower video bitrates led industry stakeholders to develop H.264 AVC. Various standards for video encoding existed even before the advent of H.264 AVC. While different manufactures can create their products differently, they will all need to follow the same standards. They can operate effectively only if the processes to encode and decode videos are standardized. Various manufacturers create hardware and software products to cater to the video streaming space. A decoder converts them back into a format that isn’t compressed. When streaming a video, a video encoder converts the video into a compressed format. What video codec essentially does is that its encoder part first compresses the video file, and at the time of video playback, the decoder decompresses it for viewing. An encoder compresses an analog video file, whereas a decoder decompresses the video file at the device to prepare the video for playback. This would enable your viewers to watch high-quality videos on a wide range of video platforms.Ī video codec compresses a raw video file so that it can be easily streamed online. You need a codec that offers both high video quality and a lower compressed bitrate. This is where the term “codec” enters into this discussion. What Is The Role Of Video Codec in Encoding? This process also converts such video files into formats that are compatible with different browsers and devices. The term “video encoding” refers to the process of compressing raw video files into a particular format for video streaming. You will find a smaller file much easier to transfer over the Internet and the streaming is also seamless. Video then takes up less space when you store it. This is why raw files are compressed to deal with these challenges. Giving the viewer a very bad user experience. There might be several lags and buffering while streaming video. If a video streaming platform directly streams raw video files, then it will face challenges. In the raw form, a video file takes up quite a bit of space. What Is The Role Of Video Codec in Encoding?Īn Introduction To H.264 Advanced Video Coding (AVC)īefore you understand what H.264 AVC is, you’d have to know about what is video encoding and what role video codecs play in this before we go on to describe H.264 AVC.An Introduction To H.264 Advanced Video Coding?.That is why we at the Brid.TV video platform use this codec to ensure our publishers can save up on space without compromising the viewing experience of their audience. If you ask us, despite its slightly inferior performance, H.264 still reigns as the industry standard, and it doesn’t seem to be going anywhere. Do you work for a large broadcasting company looking to make the streaming process more efficient? Then you might get more bang for your buck with H.265. H.265? Are you a content creator looking to start live streaming from the comfort of your bedroom? Then H.264 should be more than enough for your needs. So which one should you choose, H.264 vs. Lastly, if you’re planning on using an online video CMS to host, manage, and distribute your content, you should know that most online video platforms only support H.264. Estimates show that HEVC is supported by only 30% as many devices as AVC, and fewer video file formats support HEVC than AVC. The relatively limited device and browser compatibility for H.265 widens this gap even further. Due to this, the popularity of this codec is still lacking. For starters, the processing power necessary for HEVC to work makes the required hardware quite costly. As advanced as this codec is, it still has significant drawbacks. However, this doesn’t mean you should switch over to H.265 and never look back. All of this makes for a much more efficient video compression process. It also has over three times as many intraframe motion prediction modes - 35, as opposed to AVC’s nine - and uses more advanced prediction technology. It requires half as much bandwidth as H.264, both for encoding and broadcasting, while retaining the same video quality. Mkv, mp4, qtff, asf, avi, mxf, ps, ts, 3gpįrom the table above, you can probably conclude that, in most ways, H.265 is better than H.264. Mkv, mp4, qtff, asf, avi, mxf, ps, ts, m2ts, evo, 3gp, f4v Let’s take a look at a side-to-side H.264 vs. Now that we’ve covered the basics of each of these codecs, it’s time to crunch some numbers.
