Audio Video Interleave or AVI files are a popular video container created by Microsoft in 1992 and are the standard across Windows machines. AVI is often used to save uncompressed, or lossless video, but because of this AVI files tend to be very large - 2-3 GB for every minute of video. AVI files are one of the few container formats that support alpha channel, or transparency.
The video container format MPEG, written MPG back when Windows could only handle 3 letter file extensions, is abbreviated from Motion Picture Experts Group. Video compression formats MPEG-1 and MPEG-2 are generally used, with resolutions up to 720i, which has now been superseded by MPEG-4 Part 2, which is stored in the container format MP4.
You might want to convert AVI files to MPG to reduce the file size, for sharing or streaming over the internet, but you should consider converting instead to MP4 or MOV as you may be able to reduce the file size further whilst maintaining image quality, and both of these other file types are far more universally supported.
NOTE: It's important to distinguish between file container formats and compression formats, or codecs. For example, MP4 is a container, and can hold different types of video compression, for example, MPEG-2 Part 2, MPEG-4 AVC, or HEVC, as well as audio (again compressed in a variety of formats) and metadata (for example subtitles). Some codecs can be wrapped in multiple different containers. Containers are sometimes referred to as file extensions, e.g. MOV, MP4, or AVI, but it's important to remember that there can be different types of video within these file formats.
VideoStudio is more than AVI to MPG converter. We built VideoStudio to convert multiple file-formats including the formats below.
