A cached preview is a small, low-quality version of a video that is stored on a user’s computer or device. This allows the video to be played quickly and easily without having to wait for the entire video to download. However, in order to create a cached preview, at least two frames of the video must be available. This is because the cached preview is created by taking a snapshot of the first two frames of the video and then compressing them into a smaller file size.
Cached previews are important because they allow users to quickly and easily preview a video before deciding whether or not to watch it. This can be especially helpful for videos that are long or that have a slow download speed. Additionally, cached previews can be used to create thumbnails for videos, which can be helpful for organizing and finding videos.
The concept of cached previews has been around for many years, but it has become increasingly important with the advent of streaming video. Streaming video is a type of video that is played over the internet, rather than being downloaded to a user’s computer or device. This means that users can start watching a video immediately, without having to wait for the entire video to download. However, streaming video can also be slow and unreliable, especially if the user has a poor internet connection. Cached previews can help to mitigate this problem by providing users with a quick and easy way to preview a video before deciding whether or not to watch it.
