Main video formats: AVI.MPEG, WMV, MOV, ETC
MPEG, different codecs for each use
It is based on the QuickTime format, which we will talk about later. In addition to video and audio it also allows storing subtitles or still images. Another of its advantages is that with MPEG you can stream. It is the standard format for digital video compression and depending on the type of codec it will be ideal for one use or for another.
If your goal is to burn your video to CD, MPEG-1 will be the codec you have to use. On the other hand, if you want a quality product on DVD, choose MPEG-2. When you want to create an audio file, your codec is the famous MP3. And finally, probably the most used by users, MP4 for the web.
If you are thinking of including a video in your Editafácil publication, we definitely recommend the mp4 format
AVI, quality but heavy
AVI is a digital video storage standard created by Microsoft in 1992. With the AVI format, videos of high quality but too heavy are obtained, therefore its use for the Internet is not recommended.
There are different compression codecs for AVI, but DivX and XviD offer the best compression-quality ratio.
AVI is ideal for storing original videos directly from the camera encoded in DV, it also allows including multiple audio streams, that is, including soundtracks in different languages.
MOV, the Apple format
MOV has been developed by Apple and has its own codec that is updated regularly. In addition to the MOV extension it can appear with the QT (QuickTime) extension
It has a very good quality-to-weight ratio, which makes it an ideal format for the web. Like the MPEG format, AVI also supports streaming.
Digital video format
WMV, Windows Media Video
It is a set of compression codecs that, as its name suggests, belongs to Windows and although it can be viewed by different players, nothing is better than Windows Media Player. It can even be a problem for users who do not use the Bill Gates operating system.
The result file is usually packaged in a multimedia container such as AVI, if it is only video in WMV and if it is only audio in WMA.
Occasionally, WMV format videos include features derived from the use of DRM (digital rights management) that prevents the viewing of the videos, but that can be easily removed with utilities such as SIdda or drm2wmv.
Windows Media Video: WMV
Here we leave you our small summary of digital video formats, and although not all of them are, yes they are all of them. Do you use any of these formats? Would you recommend another?
