Identification and description ![Explanation of format description terms](info.gif)
Full name | QuickTime Video, MPEG Codec |
Description | File format that wraps a MPEG video bitstream with other data chunks, e.g., audio.
[The compiler of this document believes that this refers to MPEG-1. Recent releases of QuickTime production software (version 6.x) are capable of producing MPEG-4 files but this may mean files that conform to the ISO BMFF (Basic Media File Format), saved with the mp4 extension.] |
Production phase | Used as a final-state format for enduser delivery; may also be used as a middle-state format, e.g., as the video source when producing lower-resolution streaming versions. |
Relationship to other formats | |
Subtype of | QuickTime |
Contains | MPEG-1 encoded video |
May contain | Audio streams not documented at this time |

Normal rendering | Good support. |
Clarity (support for high image resolution) | Moderate, given that this is a format used for compression and does not support interlaced video. QTV_MPEG would be expected to provide the highest quality of the QuickTime codecs described at this web site, although at relatively high bitrates. |
