There are complicated relationships between the video quality, the amount of data used to represent the video ( bitrate), the complexity of the encoding and decoding algorithms, sensitivity to data losses and errors, ease of editing, random access, as well as an end-to-end delay (latency). As a result, decompressed videos have lower quality than the source ones for there is insufficient info to accurately reconstruct the original videos. That is to say, the compressed videos lack some information present in the original videos. Usually, the compressed data format conforms to a standard video coding format. What Is A Video Encoder?Ī video encoder refers to a device, either software or hardware, that (only) compresses digital videos, whereas a device that (only) decompresses a video is called a video decoder. In the context of video compression, “codec” is a portmanteau of encoder and decoder. What is a video codec? A video codec is a kind of software or hardware that compress and decompresses digital video. To learn video encoder, just get to know what is video codec. Videos/Audio/Photos Management Tools Recommended.After reading this post, you will have a better understanding of how various formats of videos come into being. This article expressed by MiniTool Software mainly elaborates on the meaning/definition, function, types, comparison, as well as editing of video encoder (video codec).
