QuickTime: "필요한 압축 구성요소를 찾을수 없습니다"

QuickTime encountered a track compressed using an incompatible codec (COmpressor/DECompressor), or one for which the supporting QuickTime-compatible software is not installed. The message also appears with QuickTime for Windows when the codec required is not active in the Windows Registry for use with QuickTime.

The situation is not unique to AVI files. QuickTime provides built-in support for AVI, but AVI is not a codec itself. It is a file format central to Microsoft Video for Windows (VfW), and one for which a variety of codecs may be used, such as Cinepak or Indeo Video.

Though QuickTime has long supported Cinepak, QuickTime for Macintosh does not include any version of the Indeo Video codec. In order for QuickTime to play back a media track compressed with Indeo Video (or any other codec not included with QuickTime), it must be installed separately.

Each Indeo codec uses a separate compression scheme and they are not backward compatible. Users will need to install each codec
separately.The different versions of Indeo Video for QuickTime are available from the Apple Software Updates Web site at http://www.apple.com/swupdates.

Intel has developed and released the following Indeo Video codecs for use with QuickTime.
Supported QuickTime Version
Codec Filename
Indeo Video version
QuickTime 2.x or later for Macintosh Indeo Video Indeo Video R3.2
QuickTime 3.x or later for Macintosh Indeo Video 4 Indeo Video 4.4
QuickTime 3.x or later for Macintosh Indeo Video 5 Indeo Video 5.0
QuickTime 2.x for Windows (16-bit) Iv32qt16.qtc Indeo Video R3.2
QuickTime 2.x for Windows (32-bit) Iv32qt32.qtc Indeo Video R3.2
QuickTime 3 for Windows Indeo4.qtx Indeo Video 4.4
QuickTime 4 for Windows ir50_32.qtx Indeo Video 5.0
NOTE: Later versions of Indeo Video cannot handle tracks compressed with earlier versions. For this reason, more than one version of the codec can be installed at the same time.

WHICH CODEC WAS USED?
Using the QuickTime MoviePlayer or QuickTime Player, you may be able to determine which codec was used to compress an audio or video track:

- Open the file in QuickTime Player.
- Choose Get Movie Properties from the Movie menu.
- Choose Sound Track or Video Track from the left pop-up menu in the Properties window.
- Choose Format from the right pop-up menu.

The Data Format section shows the codec. In the example shown, the Intel Indeo Video R3.2 codec was used to compress the movie "MyVideo.avi".
