What is AVI?
AVI (Audio Video Interleave) is a multimedia container introduced by Microsoft in 1992 as part of the RIFF family. A .avi file stores video and audio in separate streams, interleaved for playback, while relying on external codecs. Common combinations include MPEG-4 Part 2 or H.264 video with PCM, MP3, or AAC audio, though compatibility varies by player and codec pack. Because the format predates modern features, AVI lacks standardized support for B-frames, advanced subtitles, chapters, HDR, and efficient streaming; files can be large due to limited compression tools and overhead. Despite this, AVI remains widely readable by editors and players (e.g., VLC, Windows apps) and is often converted to MP4 or MKV for smaller sizes, broader metadata, and web-friendly streaming.
What is AIFF?
AIFF (Audio Interchange File Format) is a lossless audio container introduced by Apple and SGI in 1988 for professional production. A .aiff (or .aif) file typically stores uncompressed PCM audio in big-endian byte order, with sample rates up to 192 kHz and resolutions up to 24/32-bit. Because it’s PCM, playback is bit-perfect and supports precise editing, looping, and sample-accurate markers. AIFF-C (AIFC) adds optional compression codecs such as IMA4 and µ-law, though plain AIFF remains most common. The format supports metadata via classic chunks (NAME, AUTH) and modern ID3v2 tags, and is widely compatible with DAWs like Logic Pro, Pro Tools, Ableton, and media players on macOS/Windows. Compared with WAV, AIFF offers similar quality; WAV tends to be little-endian and more ubiquitous on Windows.
