There are several different codecs and methods of compression, but the basic concepts remain the same. Most codecs use “lossy” compression methods which, at a high level, means that when a video is compressed, some redundant spatial and temporal information is reduced. “Lossless” compression...
How Does Video Compression Work? Video compression typically happens at the camera level. For example, smartphones, consumer-grade camcorders, and most professional camcorders record video in theH.264 video codec This means that, as the camera is recording, the RAW images from the video sensor...
The continual development of H.264 is why it is the best video codec for the web. Any device built in the last decade probably supports H.264 advanced video coding. This is the critical feature of H.264 since it means that any video encoded and distributed with H.264 can be watched ...
H.264, known as Advanced Video Coding (AVC), is a video codec that was released in 2003. Many video streaming services, such as YouTube and Netflix, use this codec today. H.264 was designed to provide high-quality video compression while maintaining a low bit rate, which is why it is...
What is the best codec compression? This is a hard question to answer, as it depends on your use case. The combination of MP4 and H.264 is currently the most common video configuration, used by most of the webstreaming sites as it's wide compatible with most of the operating systems an...
playback, the codec just inserts the variable parts into the original image. If something else changes, the codec will identify another original frame and all its derivatives and repeat the process. This algorithm is called “motion compensation” and is one of the main ways video data are ...
That’s what Video-on-Demand (VOD) is — videos you can watch when you “demand” it. Case in point: If you’ve ever watched videos on YouTube, Netflix, Hulu, Apple TV+, or any other video streaming service, those videos are on demand because you can watch them whenever you want...
CoreAVC is a proprietary video codec that is used for decoding MPEG-4 AVC or H.264 video formats. The decoder is popular for its speed, which in some cases is on par with hardware-based decoders. CoreAVC is great for older PCs that include single core processors or worse, as it ...
Uncompressed 8-bit or 10-bit:This is one of video’s great misnomers. Uncompressed video is actually compressed using Chrome Sub-Sampling! We’ll explain what that means below. It is a codec used for editing. AV1: The new lossy codec on the block. Many experts predict thatAV1 will beco...
16:9 is considered widescreen and best suited for HDTV broadcasts and most desktop video players. This rectangular format helps capture more of the action and works well for large audiences or sporting events. Lastly, before choosing a specific encoder/codec combination, be sure to check with ...
