What is WAV?
WAV (Waveform Audio File Format) is a RIFF-based container most often holding uncompressed PCM audio. Because PCM stores samples directly—no perceptual compression—WAV delivers bit-perfect quality and sample-accurate editing, making it a staple for recording, mixing, sound design, and archival masters. Common settings include 44.1–192 kHz sample rates and 16–32-bit depth, mono to multichannel. WAV supports metadata via LIST/INFO, BWF (Broadcast WAV, with BEXT timecode and loudness fields), and optional iXML. Classic WAV tops out around 4 GB per file; RF64 and WAV64 variants remove that limit for long multitrack sessions. While WAV is universally compatible across DAWs and operating systems, files are large; for lossless storage with tagging, many users compress to FLAC or ALAC and export WAV only for production and delivery.
What is MP4?
MP4 (MPEG-4 Part 14) is a flexible multimedia container built on the ISO Base Media File Format. A .mp4 bundles video, audio, subtitles, and metadata into track-based “boxes,” making it ideal for storage and streaming. Common video codecs include H.264/AVC and H.265/HEVC; audio is typically AAC, with ALAC or Dolby Digital (AC-3) sometimes used. MP4 can carry chapters, thumbnails, and subtitle tracks such as 3GPP Timed Text (tx3g), and it supports HDR signaling with HEVC (e.g., HDR10, HLG). Fragmented MP4 (fMP4) powers adaptive streaming like HLS and MPEG-DASH. Because virtually all browsers, phones, TVs, and social platforms play MP4—especially H.264/AAC—it’s the default choice for web video delivery. Editors and players (VLC, QuickTime, Premiere, Resolve) open MP4, and remuxing to MOV or MKV is often lossless when codecs match.
