The compression can be either lossy or lossless. CodecsĪ codec is what compresses and decompresses a video file. Both the container and codec result in the video file format. There is also a container that bundles everything together and ensures your video works with whatever video player you have and a codec that compresses and decompresses your video. These parts include the actual video portion, audio streams, and additional information such as metadata, optional subtitles, etc., all of which must work together. Second, videos have many different parts that need to be put together into the final package. So, keep in mind that the format you pick will largely determine how small or large the final video file will be. With video resolution increasing by the day, the file size also grows, therefore, requiring that you select the right format. Video file formats are essential for two primary reasons.įirst, they help determine the final size of your video file.

Mpeg is of three types: Mpeg_ MPEG 1 (mpg), MPEG 2 (m2v) and MPEG 4 (mp4).ĭivX, which works with a certain type of MPEG-4 file, and was often used to rip DVDs in the pre-HD era Mpeg is also a container as well as a codec. Mpeg, uses the key frames within the coded footage. Codec interprets with file and plans how to play the file on your screen. Codec makes use of an algorithm to shrink/compress the size of Audio/Video files and then decompress it when needed with such a loss of quality that can’t be observed by naked eyes. An encoding compression algorithm, video codec (encoder/decoder) processes the video files and stores it in a stream of bytes. Usually a video is compressed to make it manageable, in such an order that it occupies less space with negligible loss of quality. Leaves find a larger file which become tough to handle.
Lossless Compression - It compresses the data file without much compromise over the quality, still it is not recommendable as compression takes place at a negligible level. Leaving behind a very fine line between quality and size of the file. Lossy compression - Compresses the data file in such a way that it loses some of the original quality data but achieves them in much smaller file sizes. Then these may be wrapped up within any file container. Though each data stream is first encoded/compressed (eg: video stream can be encoded using H.264 and an audio stream can be encoded using AAC compression stream) then container formats goes through compression to compress all the information into a compact file(eg a zip file). Inside each audio and video track, information is stored in compression scheme language like H.264, MPEG.

MP4 (mainly used by Apple in the iTunes Store) A container exists for the bundling of all the audio, video, and codec files into single organized package. This can hold tracks of audio, video and audio/video codecs, subtitles, metadata.

Well, file formats being the containers that hold all the information -very similar to a. Multimedia data streams should be encapsulated together in a container format to be useful in stored or transmitted form. all these extension denotes the video file format. When you come across any video file, you must have noticed that it ends with an extension.
