What is a Video Format?
A Video format is a file format for storing digital video data on a computer system. Videos are generally lossily compressed (irreversible compression) to reduce size while storing.
A video file in general consists of a container that contains video data in a video coding format, audio data in the audio coding format, synchronization information, subtitles, and metadata.
Types of Video Formats
1. MPEG-1: MPEG-1 can compress VHS quality raw videos and CD audio down to 1.5 megabits per second. It does not compromise too much in quality. This made it one of the most popular and widely compatible video and audio formats.
2. MPEG-2: MPEG-2 can compress video and audio for higher quality videos like DVDs. It is used as a compression scheme for over-the-air digital television, satellite TV services, digital TV, and DVD Video. It can capture video and audio at 6 megabits per second.
3. Windows Videos Format (WMV) WMV was developed by Windows for web streaming applications. It now supports a more specialized context. WMV files are the smallest files all over the web as the file size decreases significantly after compression. This results in poor quality.
