Get information on the network about the various existing video encodings: the question “what is the best format?” I have not yet found an answer. For now, to maintain a large video in HD-TV format (1080 × 720), the best seems to be the code adopted by Microsoft “h.264 / MPEG4 part10”, also called H.264 Advanced Video Coding (AVC), used on blu-ray discs. The “container”, ie the file format, can vary from .M2TS, from bluray, to .MPEG4.
The following is a diagram of the main forms of video compression:
Divx
He is the most famous coder, the one who changed the history of online video transmission. The basic version is free, the paid version (the Pro version) adds better encoding skills (ie for those who want to create Divx with higher quality than the standard version). The latest versions add full encoding and screen support to the HDTV standard.
Xvid
The open source encoder that competes with Divx Pro. With it you can create high quality videos.
x.264 (AVC / H.264)
The H.264 / AVC encoder is the latest generation (paid) video compression encoder, which achieves the best results (intended both in terms of compression and final quality). It also comes with high definition (HD) compression, designed for TV and Blu-Ray. Unfortunately, the official version of the encoder is shareware (already used in various encoding programs, including Nero), but there is a free version (even open source) called x.264, which can be used for encoding / decoding. In some open source video editing programs, such as AviDemux, this encoder is already built-in and can be used like any other encoder (although a video created with it is currently incompatible with divx player programs). is already embedded in some media players, such as VLC or others.
MKV (Matroska and Haali splitter package)
The MKV format is not a format, but a container (like the avi). Inside it can accommodate the most different codecs, such as Xvid, Divx, H264, AAC, etc. To watch .mkv movies, which recently seem to be spreading more and more (and will become more and more, given the increase in HD 720p or 1080p video, HDTV and Blu-Ray), the Matroska package or a video player that supports this form / container inherent.
FFDShow
It is a very useful open source and filter encoder package for displaying multimedia content such as divx, xvid, mkv, h.264, ac3, etc. It is also widely used by free applications such as BD Rebuilder, RipBot, etc., requiring the operation of your presence.
