Video and Audio Encoding/decoding technology:

(1) silent FLC

(2) audio and visual Avi

(3) Both capacity and quality MPEG

The quality of MJPEG encoding is quite high. It is a kind of encoding with the highest quality requirement. It is a non-linear system.

Therefore, it tries its best to use the jitter algorithm during the Encoding Process (you can also set it to not shake) to simulate the effect of the true color. This algorithm is almost messy when the color value gap is not very large,

 

The sound in nature is very complex, and the waveform is extremely complex. We usually use pulse code modulation coding, that is, PCM coding.

PCM converts a continuously changing analog signal into a digital code by sampling, quantization, and encoding. PCM is equivalent to lossless encoding.

Calculation of the bit rate of PCM audio streams: Sampling Rate Value × sampling size Value × number of audio channels bps. The common audio file sampling rate is 44.1 kHz.
