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.

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
