What is video coding? Explain how to generate video distribution and basic knowledge files.
What is the reason for the
coding?
What are the four points to take into account before coding work? Is
important to perform the coding according to the purpose of the video.
Recently, many people publish videos in video distribution services such as YouTube. Have you ever heard the word encoding in such a situation?
The coding refers to compressing and encrypting format data, such as video and audio, according to certain rules, and converting them to another data format.
If a video file taken with a video camera is distributed online as it is through a video distribution service, the amount of data will be too large and it can be difficult to see it comfortably depending on the viewer’s Internet environment.
When coding the video he recorded and created, he can turn it into adequate data for his purpose and purpose, and he can see it comfortably.
On this occasion, for those who want to publish a video, I will explain the importance and necessary of the coding work.
What is the reason for coding?
Coding is the conversion of signals and data according to certain rules. It mainly has the meaning of “coding”, “encrypted”, “data compression”, etc. Coding is a necessary task when creating a video. First, I will explain the reason for coding.
A video is like an animated book, and dozens of images per second are recorded, and the data is processed so that they seem to move when connecting them. The frame rate (FPS) indicates how many images are projected per second and, at 20 fps, it means that 20 frame frames per second are used.
Depending on how it records and creates the video, the value of the frame speed can increase, which makes it difficult to see it comfortably. The coders, which are hardware or software to convert data into several formats, are necessary for coding.
Coders are distributed abundantly and some programs can be downloaded free of charge. “XMedia Recode” and “Handbrake” are relatively well known as free software. Try it and find an encoder that is easy to use.
