What is MPEG?
MPEG (.mpeg or .mpg) usually refers to the MPEG-1/2 Program Stream container plus its classic video codecs. An .mpeg file typically holds MPEG-1 or MPEG-2 video with MP2/MP3 (or sometimes AC-3) audio, multiplexed for smooth playback on computers, set-top boxes, and legacy DVDs/VCDs. The compression is lossy and block-based, great for the era of low bitrates, but less efficient than modern H.264/AVC or HEVC at the same quality. Most players—VLC, Windows apps, QuickTime, and many TVs—open MPEG natively; editors can often remux to MP4 or MKV without re-encoding if codecs are supported. Note that MPEG-2 Transport Streams use .ts or .m2ts, and MPEG-4 files usually use .mp4, not .mpeg. Converting old MPEG to MP4 (H.264/AAC) yields smaller files and broader web compatibility.
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.
