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.
3GP is a container format based on the ISO file format, that contains video compressed with the H.263 and H.264 compression standards. 3GP is associated with older mobile phones, typically pre-smartphone era, and was the filetype required for sending video in MMS messages.
You might want to convert AVI files to 3GP to transfer them for playback on an older mobile phone. If you simply want to reduce the file size and don’t plan to transfer the videos to an older phone, because 3GP is becoming a redundant file type, you should consider converting instead to MP4, MOV or AVI as 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 3GP converter. We built VideoStudio to convert multiple file-formats including the formats below.
