Types of Files QuickTime Supports
Mpeg 2 File Extension
You can open (import) dozens of types of media with QuickTime. Some of the formats
you can open in QuickTime include the following:
 Video formats: MOV, MPEG-1, MPEG-2,
Quicktime Mpeg 2 Component Files
I can view these in VLC but can't edit them or import them into Media Composer. I have tried converting them in VLC and then importing into MC but the imported copies are unstable (juddery). I have MPEG Streamclip but it needs Quicktime MPEG-2 playback component to enable it to play these files - I believe that is long gone on my system. QuickTime MPEG-2 playback component supports a number of files such as mpg, mpeg, vow, vroom, m2v, m2a, and m2s. Audio files supported by this component are any of the above files that contain audio layer 1 or 2. This component could also play back non-protected DVD discs as well. Or you have the (fantastic tool, BTW) MPEG Streamclip from Squared 5 but you don’t have (and can no longer buy) the QuickTimeMPEG2.component required by MPEG Streamclip in order to be able to handle MPEG-2 data. QuickTime has the ability to play back MPEG-2 content via the QuickTime MPEG-2 Playback Component. It is available as an add-on to QuickTime 6 or QuickTime 7. Learn more about MPEG-2. Once you have ordered the MPEG-2 Playback Component through the Apple Online Store, the component can be accessed via your account.

MPEG-2 playback is available via the QuickTime MPEG-2 Playback Component, sold separately at the Apple Store
online. Because some file formats can contain many different kinds of audio and video, QuickTime may not be able
to play all audio and video formats within a particular file format.
