Video compression tools work by using video encoding algorithms known as codecs. Codecs, by encoding video sequences, reduce the number of bits needed to represent a video. After encoding, the video sequences are wrapped in video containers (such as MP4 and AVI) and then output as compressed videos.
Video compression is a process you can use to reduce the file size or change the format of videos. Compression enables you to reduce the amount of storage resources needed to store videos, saving costs.
Video compression is the process of reducing the number of bits needed to represent a video without compromising its visual quality. The purpose of compression is to make the video occupy less space than the original file and to facilitate its transmission over the Internet. Here's how it works.
Video Encoding
In this blog, we’re going to explain the fundamentals of the video encoding process (compression) in simple terms Motion Jpeg
Now imagine we record a video of this same scene with the cyclist moving: The camera actually captures a sequence of still images: and the JPEG Moving Picture Experts Group Codecs (MPEG).
To eliminate temporal redundancy, inter-frame compression techniques were invented (inter meaning between or among) I, B, p Frames
Let’s take a high level look at how it works. The encoder caches a certain number of frames and applies an intra frame algorithm to the first frame Group of Pictures
For several reasons (for details please read this blog here), the above sequence of B and P frames can’t be infinite. At some point Conclusion
We hope that you have a better understanding now of how common compression algorithms work, along with key concepts such as group of pictures
