How to Choose a Video File Format

When choosing a video format, it is hard to tell which one is the best. It depends on how you want the quality and size to be. If you are making a video for the web, you should choose some small formats like MP4 and WEBM, even though they may lose the quality of the video. But if you want a high-quality video, you may choose uncompressed formats, but you may need to put up with large file size.
