    Hello everyone,

    so now we are talking about conversion into another format?
    => only one serious alternative: x264!
    Get yourself xmedia-recode or FormatFactory and have fun Both are freeware, but use opensource programs as backend.
    To be honest, there are a few more very handy tools out in the wild: h264encoder, HandBrake, WinFF, FFconverter,...
    If your are willing to make your bacchelor of converting, take the commandline-prog: x264.nl has the most recent version of x264.exe (version 1318 at this moment)

    Best regards!

    Edit: If you are talking about packing a movie into an archive, please stop here and move to this topic.

    Edit 2: I removed MediaCoder because it claims to be OpenSource but isn't for a few months already.

    and the matroska page,

    which has some nice links itself:

    Hello everyone,

    hmmm... S.U.P.E.R. is suspected to install more than the user really wants, but if that's not the case, it's really worth a try! If I remember correctly, it can encode into flv-container with h264-codec.
    Regarding Matroska (mkv): isn't it a container-format? As far as I know it can be filled with various kinds of encoded material, so the size would depend on the input, wouldn't it? If that's true one would still have to find a powerful codec. Hence x264 comes into discussion. There are few codecs that compress equal or more, preserving the same quality (to mention potentionally one: snow). And even less that can be shown by media-players or even hardware.

    Edit 2: Having said that about S.U.P.E.R. I just found FormatFactory 2.15 trying to install some toolbars too! Keep your eyes open!

    Best regards!

    For improve compression/quality you have to use Avisynth. I make DVDRip. I compress DVDR in 200-250mb. Nice, no?? I suggest you that you can use "HybridFuPP.avs" filter with Avisynth. Last Avisynth version is 2.60 beta 2.

    P.S. My last rip is "star trek" (120minutes) 4,5 Gb >> 250 mb

    When you play a .mkv file in VLC player, Cntrl+J shows the used video- and audio codecs.
    Avc1/h264 is mostly used for video. In web-releases it is called x264, after the x264 encoder.
    Audio varies more, but a52/ac-3 is topdog. Audio and framerate can influence size a lot.

    yes Fallon, that's right. Audio films (for example Star trek) has size of 16 mb!!
    I use enc_aacPlus with Normalize.exe, the quality is High!!

    I've been on the topic too recently, however I was looking for a lossless recompressor...and found nothing.
    I couldn't even find a way to gain by compressing PCM audio.

    Does anybody know anything that could help?

    You can try and ask at the doom9 forum.
    Here is a small app I like to mention anyway.

    Thanks for a good pointer.
    This tool didn't do what I needed, but with help of VirtualDubMod + Avanti (ffmpeg gui) + ffmpeg I managed to make matroska files with wavpack audio.

    Cleaning up my HDD I just found an old version of GVC. I had a look if there would be some newer version / update and found FFcoder. Here (to come to the end ) I stumbled upon that codec, which claims to be lossless. I do not know anything about it's results, but sourcecode seems open.

    Edit: I removed MediaCoder from my first posting, because I just noticed that it isn't OpenSource anymore (call me sleepy, but it's true: I *just* noticed it. But It's closedsource for a few months already...) Sorry...

    Best regards!

    Thanks, but Avanti is a very nice GUI.

    Lagarith - cool, I expect we might be using codecs like this regularly when space becomes cheap enough (display resolution grows slower than HDD capacity), but it seems far from now.
    I tried to recompress a 100 MB MPG. Speed is good, but 1.2 GB output is unsatisfactory.

    Losslessly compressing artefacted video worsens the compression compared to original input IMO. It could be good for anime (with large areas of single color)
