A media container format (or typically known as wrapper format) is a format that may include varied sorts of information comparable to audio and video information. The info is compressed utilizing a codec MP3 Youtube.
A codec (a compound of coder and decoder) is an algorithm used to compress and/or decompress a multimedia information stream with the intention to scale back the quantity of bytes wanted to retailer or ship.
Some container codecs are restricted to audio, like WAV recordsdata for Home windows, AIFF for Mac and XMF; some are restricted to nonetheless photographs comparable to FITS and TIFF. There are additionally containers which are versatile; it will possibly maintain a number of sorts of audio, video and different media comparable to ASF recordsdata for Home windows, MP4 and Matroska. The commonest multimedia containers are:
- 3GP – utilized by cellphones
- ASF – commonplace WMA and WMV container
- AVI – commonplace Home windows container
- Matroska – open commonplace container
- MPEG – commonplace container for MPEG-1 and MPEG-2
- MP4 – commonplace container for MPEG-Four
- Ogg – free and open commonplace container for codecs Vorbis (audio) and Theora (video)
The distinctions between completely different container codecs come up from 5 (5) important points:
- Reputation. Broadly supported container.
- Overhead. Instance: A two-hour movie could also be 3MB bigger when in AVI than when in Matroska (MKV). The overhead is the distinction between AVI and MKV which is 3MB.
- Help new codec performance and options. Some older container codecs doesn’t help codec function comparable to VBR audio and B-frames.
- Subtitles, chapters, meta-tags, and user-data help.
- Streaming media help.
Here’s a comparability of the completely different fashionable container codecs right now (from Wikipedia).
