Video distribution Advantages and disadvantages of a high bit rate
The video bit rate is calculated separately for video and audio and added together.
The sum of the video and audio bit rates is called the oval bit rate (total bit rate).
Expressed in a formula
Oval bit rate = video bit rate + audio bit rate
High bit rate benefits
The higher the bit rate, the better the picture and sound quality, and the lower the bit rate, the worse the picture and sound quality.
However, note that if the video bit rate is high, there are cases where the video bit rate is high and the image quality is good, but the audio bit rate is low and the sound quality is poor. On the contrary, there may be cases where the image quality is poor and the sound quality is good.
High bit rate video basically has the advantage of improving image quality and sound quality, but you also need to understand the disadvantages.
Disadvantages of high bit rate
The higher the bitrate, the more net bandwidth is consumed and the more playback load is applied.
For example, increasing the bit rate from 500 Kbps to 1000 Kbps doubles the net bandwidth usage and doubles the playback load or more.
It is easy to increase the bit rate for high image quality, but if you increase the bit rate too much, the CPU will become overloaded and you may not be able to reproduce it well, so be careful.
Especially when the radio wave of the smartphone is bad or the band is limited, it may not play smoothly at a high bit rate.
Even if the bit rate is increased, the image quality and sound quality do not improve above a certain level.
In fact, increasing the bit rate does not mean that the image quality and sound quality will increase without an upper limit.
For example, if the image quality of the original video material shot by the camera is 100, even if it is converted at a high bit rate by video editing software or encoding software, a high-quality video with a quality of 100 or more image of the original video will be created. You can not.
No matter how high the bit rate is, if the quality of the original video material is poor, the quality will not be better.
