![]() Standard video compression formats can be applied to multiple video encoders and decoders from multiple sources. Thus, multiple codecs are available in the same equipment, reducing the need to select a single major video compression format to achieve interoperability. Many video compression formats can be implemented on personal computers (PCs) and in consumer electronics devices. Some video encoder H.264 settings need to be set when streaming to an HTML5 video player. Especially, video codecs are widely used in programs that record or transfer videos, which may not be feasible with the high data volumes and bandwidths of uncompressed video.Īny video file or stream can be encoded with a wide variety of live video formats. Video codecs are applied in DVD players, Internet video, video on demand (VoD), videotelephony, digital cable (HDMI), digital terrestrial television, as well as various other apps. 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. ![]() ![]()
