\nUsing MPEG Streamclip for Mac #02: Compression and Demultiplexing<\/p>\n

In the second video tutorial of the MPEG Streamclip series, we focus our attention to application’s export and demuxing functions. And this is a good opportunity for us to discuss basic characteristics of some of QuickTime components. So we spend several minutes explaining basic characteristics of some of popular QuickTime compressors.<\/p>\n

Furthermore, we also explain briefly how the MPEG-4 compression works. We will answer the following questions:
\n
<\/br>
\n
<\/br><\/p>\n

  • What is Multipass?<\/li>\n
  • What is B-Frames?<\/li>\n
  • How does the Quality slider work?<\/li>\n

    <\/br>
    \n
    <\/br>
    \nMeanwhile, if you have MPEG files to edit, it is essential that you know how to demux video files. Why? By demuxing an MPEG file into audio and video streams, you can deal with them separately. And Final Cut Pro 6 recognizes M2V files. So you don’t have to convert MPEG-2 files into DV any more. If the video clip contains AC3 audio, you can just take AC3 and convert it into AIFF or whatever QuickTime or Final Cut Pro can decode. Then you can read them separately or mux the original track and a new audio file into an independent MPEG-2 file if you want. (Watch “Using MPEG Streamclip for Mac #03” for MPEG Streamclip’s muxing function.)<\/p>\n
