Before converting a video or movie, many people ask what is the best video format, that is, with the best compromise between file weight and video quality.
It is not easy to answer this question, also because we first have to define well what is meant by video format.
For example, many believe that AVI is a simple video format, but it is not.
.AVI is a container, not a format that can be different types of video and audio “formats” inside. In fact, video formats such as .AVI MPEG-1, MPEG-2, MPEG-4, WMV, RealVideo, Theora and these MP3, WMA, AC3, DTS audio formats can co-exist within
In practice, you can find within an .AVI video, on an MPEG-2 video (divx) and AC3 audio format
The MPEG-4 format is instead a compressed .mp4 format (mp4v and mp4a). If you convert from .mp4 to .AVI, you will have “unpacked, unzipped” the two .mp4 formats (audio and video, MPEG-4 video, MPEG AAC audio or MPEG-4 video, and MPEG 1/2 / 3 mpga audio layer
by downloading a .AVI file, instead of selecting another container (for example .MKV), you will have decomposed the .mp4 audio and video format inside a .MKV -container.
For this reason, AVI, MKV are larger video files, precisely because they are not compressed. Instead, the MPEG-4 format is the compressed video format. Depending on your needs, you can choose one or the other format.
If you are looking for a format that has a good compromise between QUALITY, not the excessive weight of the video and COMPATIBILITY with any device (smartphone, tablet, smart TV, computer, etc.), we recommend using FORMAT .MP4
To convert between video or audio formats and also make a number of improvements, we recommend the one that is undoubtedly the best video converter and audio converter, as it also allows you to normalize the volume level, to change the pitch without changing the speed and vice versa, to equalize and many other interesting options, at a very moderate price, generally lower than the typical video converter.
