    Absolutely no idea where to post this on AVF so thought I would post it here..

    What does MP4, MKV, H-264 (or x264??), Anamorphic etc all mean. (Actually I know what MP4 is and i'm sure MKV is just another file format similar to MP4 but no idea about the rest).

    An example: I was looking at downloading (legally) a file that had been converted to play on my PC that was originally on DVD.

    I go so confused with the acronyms I gave up...

    Here is an example of what I mean:

    container: .m4v/MPEG-4
    anamorphic: 716x358 -> 848x358
    AVC video: x264 @ 1850 kbps
    AAC audio: faac @ 160 kbps

    Help!

    Thanks, Chris.

    Yeah,acronyms and home cinema go hand in hand,anyhoo,MPEG stands for Motion Pictures Expert Group,wiki can explain it,MP3,4 or whatever number,stands for music protocol,H-264 is another term for mpeg4,tis' used on hd-dvd and blu-ray,it's a compression algorithm.

    Anamorphic is best explained here.

    http://en.wikipedia.org/wiki/Anamorphic_widescreen

    avc is another algorithm,is the same/similar to h-264,acronym is advanced video coding/codec.

    and finally m4v is here
