AVI is called Audio Video Interleaved, the so-called "audio video interleaved" is the ability to interlace video and audio for synchronized playback. The advantage of AVI format is that its image quality is good and can be used across multiple platforms. But, the disadvantage is that its volume is too large, and even worse, the compression standard is not uniform.
The most common phenomenon is that high-level Windows Media Player cannot play AVI videos that were edited using early coding, while low-level Windows media player cannot play AVI videos that were edited using the latest encoding. Therefore, when we perform some AVI format video playback, the video cannot be played due to video codec problems or even if the video can be played, but there are some inexplicable problems such as the inability to adjust the playback progress and the playback of only sound without images.
