    Default Video questions

    1) I was always wondering about why windows media play supports .avi files and yet you need a codec player to play them. Why is that?

    2)Is it possible to convert a video to its highest quality.

    3)I noticed most of all high quality video's are .mkv why is that?

    1 - Because AVI is a container, what you put inside that container is up to the encoder, so if the encoder put a XDIV video inside, WMP doesn't have the necessary decoder to understand what is that. Thats where Codecs come into play

    2 - You mean increase its quality? or in size? In size, yes easy (but it decreases quality)
    But in quality, like decreasing blur and scanlines etc.. Hard, very hard, thats one of the job of the encoder.. he choses a codec, that have all thoses settings, after that he apply to the video.
    But once its done once, its difficult to up the quality..


    3 - MKV is another container format like AVI, but the difference it has the capability to hold UNLIMITED numbers of Videos streams, Audio Streams and Subtitles inside. Not only that because it works with streams, you can have the "Soft sub" or a "Dub" on the same file.

    But if for the HD videos comming in MKV.. its just has some nift features its open source then its counterpart AVI

    I wonder if it's really unlimited or a value like 64, 255 or 65535.

    ^ I think the "unilimted" is just figurative.

    But you can atleast have a MKV that has
    Raw video <Video stream
    Japanese Voices <audio 1
    English Voices <audio 2
    Japanese Karaoke <Sub 1
    English Subtitles <sub 2

    I don't see where I saw it, but it seems that AVI support to HD 720p / 1080i is somewhat lacking

    Yeah, but usually with programs, they are either binary or hex or whatever.
