To bedzie dobra wiadomosc dla wszystkich poczatkujacych z Capturami. Oto jest znane cos takiego jak kompresja w locie. Wlasnie wczoraj dokonalem odkrycia skad ja to mam. Otorz zainstalowalem sobie kiedys takie narzedzie jak Microsoft Multimedia Tools nie mylic z (Player) otorz cos takiego ma w sobie kodeki. Zreszta podobny efekt uzyskamy prawdopodobnie istalujac Multimedia Player 6.4 (aktualnie na stronie MS do sciagniecia) Starsze nie maja MPEG-4 codec'ow. Nie jestem jednak pewien bo Playera instalowalem pozniej. Wyprobowalem i dziala znakomicie. Nalezy pamietac by ustawic format VIDEO na 24-bit lub 16-bit bo tylko dla tych codec bedzie dostepny. Odtwarza sie na kazdym kompie z zaistalowanym MMP nawet z P100. 100 minut 320x260 zajmuje mniej niz 600MB czyli miesci sie na plytce. Jakosc prawie jak VHS. Nie rozumiem na razie jednej sprawy . Moj program Capture tworzy tylko AVI ale widocznie skompresowany MPEG-4. Nie wiem jak to przerobic na plik MPG bo przeciez juz nie ma sensu to drugi raz kodowac. Chyba musze wyprobowac innego CAPTURA albo po prostu taka jest standardowa idea ze nagrywamy tylko AVI. ================================= Codec Description Microsoft MPEG-4 Video Codec version 1 The Microsoft MPEG-4 codec is a low to high bit-rate video codec. The advantage of this codec is that it meets the standards set by the Moving Picture Experts Group (MPEG). Use version 1 if you provide content to version 2.0 servers or players. Microsoft MPEG-4 Video Codec version 2 The Microsoft MPEG-4 codec is a low to high bit-rate video codec. Version 2 of the codec is provided for compatibility with content and encoder configurations created with version 3.0 of Windows Media Tools. Microsoft MPEG-4 Video Codec version 3 The Microsoft MPEG-4 codec is a highly scalable video codec that supports a wide range of network bandwidths. The latest version of the Microsoft MPEG-4 video codec has been optimized for the Intel Pentium III processors. Using this codec provides faster on-demand encoding and higher data rates, resolution, and frame rates for live encoding. If you are using an Intel Pentium II processor you will still experience much faster video encoding performance. Version 3 of the codec also supports multiple bandwidth and high bandwidth encoding. Additionally, it includes the video de-blocking filter which improves the video quality of your content by removing the blockiness caused by video compression - especially at low data rates like 28.8Kbps. VDOnet VDOWave VDOWave is a low to mid bit rate video codec. Microsoft H.263 H.263 is good for providing low to mid bit-rate video. This codec is optimized for video conferencing, so it is a good choice for presentations and other low-motion video content. TrueMotion RT 2.0 by Duck Duck is a high bit-rate video codec. Use this codec for .asf files or ASF streams that can be played either over an intranet (a network operating at more than 1 megabit per second [Mbps]) or locally. Windows Media Player full-install codecs The following codecs are installed as part of the full installation of Microsoft Windows Media Player: ? Microsoft MPEG-4 version 1, and version 2, and version 3 video codecs ? FhG MPEG Layer-3 audio codec ? Voxware MetaSound, MetaVoice, and RT29 audio codecs ? Duck TrueMotionRT video codec ? Vivo V263 video codec ? Windows Media Audio codec version 1 and version 2 ? Vivo V723 audio codec ? Vivo Siren audio codec ? L&H audio codec ? VDONet VDOWave video codec ? Iterated ClearVideo 1.3 ? ACELP.net Windows Media Player core codecs The following codecs are installed as part of the Microsoft Windows Media Player core installation: ? Voxware MetaSound audio codec ? Voxware MetaVoice audio codec ? FhG MPEG Layer-3 audio codec ? Windows Media Audio codec version 1 and version 2 ? Microsoft MPEG-4 video codec ------------------------------------------------------------------------- do skopiowania ze strony: 4MB http://www.microsoft.com/windows/windowsmedia/en/download/default.asp
