* Raw video: This is the uncompressed video data, which is typically stored in a file with a .mov, .avi, or .mp4 extension. Raw video files are very large and can be difficult to edit.
* Compressed video: This is video that has been compressed using a lossless or lossy compression algorithm. Lossless compression reduces the file size of the video without compromising the quality, while lossy compression reduces the file size even more but may introduce some visual artifacts. Compressed video files are typically stored in a file with a .mp4, .mkv, or .flv extension.
* Streaming video: This is video that is streamed over the Internet. Streaming video is typically compressed using a lossy compression algorithm, and the quality of the video can vary depending on the speed of your Internet connection. Streaming video is often watched using a web browser or a media player.
The format of a video depends on a number of factors, including the source of the video, the intended audience, and the desired quality.
Here is a more detailed explanation of how each type of video is represented on computers:
* Raw video is simply a sequence of images, each of which is represented by an array of pixels. The number of pixels in each image and the color depth of each pixel determine the resolution and quality of the video. Raw video files are very large because they store all of the original video data without any compression.
* Compressed video is created by using a compression algorithm to reduce the file size of the video. There are two main types of compression algorithms: lossless compression and lossy compression. Lossless compression reduces the file size of the video without compromising the quality, while lossy compression reduces the file size even more but may introduce some visual artifacts. Lossy compression is typically used for streaming video because it allows for smaller file sizes and faster streaming speeds.
