Definition: Codec
• Short for Compressor/Decompressor
• The algorithm used to make a digital file smaller, works in
the same basic way as these examples:
• Digital photo- jpeg
• Digital audio- mp3
• Can exist as software, or in a hardware device
• “Codec” is also confusingly used as a term for a Distance
Learning or Videoconferencing end point

Definition: Wrapper or Container
• The package that holds the digital information
• avi, wmv, mov, mp4
• Any wrapper will support only the codecs for which it’s
designed
• Many wrappers can support the same codec
• mov and mp4 will both support H.264 codec

Caveat
• Depending on how your computer is configured, you
might have to buy the QuickTime MPEG-2 Playback
Component from Apple Computer for $20 if you want to
work with DVDs
• http://store.apple.com/us/product/D2187Z/A
• QuickTime Pro is not required to use MPEG Streamclip

• Frame rate— unchanged
• Aspect ratio— no change unless cropping is needed
• Audio codec— MPEG-4 AAC
• File wrapper (container)— .mp4 (web), .mov (Mac), .wmv
(Windows)
• All variables are likely to change given the type and
