AVI (Audio Video Interleave) is Microsoft's legacy multimedia container from 1992, still used in Windows-based video editing, surveillance systems, and industrial applications. Despite its age, AVI remains relevant for workflows that depend on DivX, XviD, or uncompressed video. Converting 3GPP files from GSM-era phones to AVI makes them compatible with Windows-centric media tools that do not support mobile video formats.
Legacy Windows applications — from VirtualDub to older versions of Adobe Premiere — sometimes require AVI input. Industrial systems like surveillance DVRs and medical imaging stations often standardize on AVI for their video archives. If you need to incorporate GSM phone footage into one of these environments, AVI conversion is necessary.
AVI with uncompressed video also serves as an excellent intermediate format for editing. Every frame is independently accessible without GOP structure, making random access and frame-precise editing instant. For a short 3GPP clip, the uncompressed AVI size is manageable and provides the best possible editing experience.
FFmpeg reads the 3GPP source and transcodes to AVI with the selected video codec — H.264, MPEG-4 Part 2 (XviD), or uncompressed. Audio is converted to PCM or MP3, both widely supported in AVI. The AVI 1.0 container has a 2 GB file size limit, but 3GPP files are too small for this to matter. OpenDML extends this limit for larger files.
With XviD encoding at reasonable bitrates, the AVI output matches or exceeds the 3GPP source quality. Uncompressed AVI preserves exact decoded frame data. Since 3GPP files typically contain 176x144 to 352x288 video, even uncompressed AVI produces small files — a 30-second 352x288 clip at 15 fps in uncompressed RGB is only about 70 MB.

3GPP to AVI serves Windows-centric workflows where AVI is the required or preferred container. For modern cross-platform use, MP4 is generally a better choice.
