Video formats refer to the specific ways in which video data is encoded and stored. Common formats include MP4, AVI, and MOV. Each format has its own characteristics, such as compression methods and compatibility with different devices and software. Choosing the right video format is important for ensuring quality and playback efficiency. For example, MP4 is widely used for its balance of quality and file size, making it suitable for streaming on the internet. In contrast, AVI may offer higher quality but results in larger file sizes, which can be less convenient for sharing.
