AVI (Audio Video Interleave) is Microsoft's venerable multimedia container introduced with Windows 3.1 in 1992 — just one year after Apple launched QuickTime. While QT uses Apple's atom/box structure that later informed the MP4 standard, AVI uses Microsoft's RIFF (Resource Interchange File Format) with interleaved audio and video chunks. Converting QT to AVI moves content from Apple's container to one of the most universally recognized video formats in computing history.
AVI is natively supported by every version of Windows since 3.1, most hardware media players, and virtually all video editing software including legacy applications that don't support QuickTime. If you're working in a Windows-centric environment or need to deliver video to systems without QuickTime support (which was deprecated on Windows in 2016), AVI is a reliable fallback.
FFmpeg reads the QT atom hierarchy, extracts video and audio elementary streams, and re-muxes (or re-encodes) them into AVI's RIFF structure. Common output codecs include MPEG-4 Part 2 (DivX/Xvid compatible) or H.264 for video, with MP3 or PCM for audio. AVI's index structure is written at the end of the file (or optionally as OpenDML for files over 2GB).
When using the same codec and bitrate, quality is identical — the container doesn't affect video/audio quality. If re-encoding is needed (e.g., ProRes to MPEG-4), quality depends on the target bitrate. AVI at the same bitrate as the QT source produces visually equivalent results.

QT to AVI conversion provides maximum compatibility with Windows systems and legacy hardware. Despite being an older format, AVI's universal support makes it the pragmatic choice for cross-platform video delivery when modern formats aren't an option.
