Are you looking for answers to the best format for YouTube? There are many online guides, but sometimes they misuse terms and cause confusion. It is advisable to clarify a little about the best video and audio formats for videos for YouTube. In this post I will explain what is the best format for YouTube and what the most commonly used terms mean when it comes to audio and video formats.
Before you choose the best format for YouTube videos, let’s clarify a bit the concepts and terms related to manipulating audio and video files on the computer.
The codec is the part of the software that deals with the encoding and decoding of the information that make up the transmission of audio or video. The newer codecs also deal with compression and decompression. Therefore, when encoding or decoding the signal, they use mathematical algorithms that save storage space at the cost of quality. Therefore, the codecs are divided into lossless (lossless data) or lossy (lossless data) depending on whether they use compression or not.
The best format for YouTube
compression
When playing video files, compression is performed using mathematical functions that reduce the number of frames per second or the resolution of the pixels that make up the image. In audio files, compression is done by removing the frequencies that cannot be fully perceived by the human ear and the number of bits that make up the sound information.
BitRate
It is the number of bits per unit of time (Attention! We are talking about bits and not bytes). It is usually measured in kilobits per second, which is abbreviated to KBit / s or KBit / s. With more format, the more information there is per second, the higher the quality or resolution of the film or audio.
Format is a code that specifies how information is stored in a file (compressed or not). The best format for YouTube so far is undoubtedly H264, which offers higher quality due to the same size. As with most video formats, there are variants that are as high as the sub-formats for certain purposes. Youtube recommends using H264 HIGH with an automatic bit rate or 8000 Kbit / s for Full HD films and 5000 Kbit / s for HD films.
And the container?
The container is a file format that can contain independent audio and video transmissions encoded with different codecs. The most popular container formats are MKV or AVI, but the length does not indicate film quality.
