Explanation of Key Takeaways
MPEG and MPG: Same Thing, Different Names
MPEG and MPG are essentially the same thing. MPEG stands for Moving Picture Experts Group, which is a working group of experts that was formed by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) to set standards for audio and video compression and transmission.
MPG, on the other hand, is simply a file extension used to indicate that a file is in MPEG format.
In other words, MPEG is the name of the group that created the standard, while MPG is the file extension used to indicate that a file is in that format. They are interchangeable terms and refer to the same thing.
Different File Extensions for the Same Type of File
A ".mpg" file extension is typically used to refer to an MPEG program stream or MPEG transport stream, which are defined in MPEG-1 and MPEG-2 standards. ".mpeg" is another file extension for MPEG-1 or MPEG-2 audio and video compression.
In terms of file format, there is no difference between ".mpg" and ".mpeg".
They are simply different file extensions for the same type of file.
Similarly, in Portuguese, the ".mpg" file extension is used to refer to a MPEG program stream or MPEG transport stream, while ".mpeg" is another file extension for MPEG-1 or MPEG-2 audio and video compression.
Again, there is no difference in file format between ".mpg" and ".mpeg".
They are just different file extensions for the same type of file.
The same applies to the Chinese translation, where ".mpg" is the file extension for MPEG and is commonly used to store video and audio data.
Differences Between MPG and MP4
While MPG and MPEG are interchangeable terms, MP4 is a different format. MP4 is a container format that is popular for smoother playback, while MPG format is suitable for streaming DVD contents.
MPG uses MPEG-1 or MPEG-2 codec, while various options are available for MP4. MP4 supports a wide range of video and audio codecs, including H.264/AVC and H.265/HEVC, whereas MPG supports only MPEG-1 and MPEG-2.
Since MP4 is mostly used for videos on the internet, some media players don't take into consideration the MP4 format. As such, you'll find a couple of players that can't play MP4 files. On the other hand, as the pioneer of the MPEG codec, the majority of media players support MPG.
Abbreviation and Full Name
The difference between MPEG and MPG is that MPG is the abbreviated version of MPEG (Moving Picture Experts Group), which is the full name of the standard. In other words, MPEG is the full name of the standard, while MPG is just a commonly used abbreviation to refer to it.
Similarly, in Chinese, MPEG is the abbreviation for Moving Picture Experts Group, which is the full name of the standard.
So, in conclusion, MPEG and MPG are essentially the same thing. MPEG is the name of the group that created the standard, while MPG is the file extension used to indicate that a file is in that format.
They are interchangeable terms and refer to the same type of file.
MPG is suitable for streaming DVD contents, while MP4 is popular for smoother playback.
