F4V is Adobe's Flash video container built on the ISO base media file format, storing H.264 video with AAC audio. AIFF (Audio Interchange File Format) is Apple's uncompressed audio standard, storing raw PCM data at full CD quality (16-bit/44.1 kHz) or higher. Converting F4V to AIFF extracts the audio from a Flash video and expands it to an uncompressed, lossless representation that is ideal for professional audio editing on macOS.
Converting F4V to AIFF makes sense when you need to edit the audio from Flash video content in professional digital audio workstations (DAWs) like Logic Pro, GarageBand, or Pro Tools on macOS. AIFF's uncompressed PCM format avoids the decoding overhead and quality assumptions of compressed formats, giving you a clean starting point for mixing, mastering, or audio restoration. It is also the preferred import format for many Apple-ecosystem audio tools.
FFmpeg extracts the AAC audio stream from the F4V container and decodes it to raw PCM, then writes it into the AIFF container with appropriate headers. The output defaults to 16-bit signed integer PCM at the original sample rate (typically 44.1 kHz or 48 kHz). Since AAC in F4V is lossy, the conversion expands the compressed audio to uncompressed form — this does not restore lost information but provides a lossless-editable format. AIFF supports metadata chunks for title, artist, and comment fields.
The AIFF output will be a faithful uncompressed representation of the AAC audio that was stored in the F4V. Quality is limited by the original AAC encoding — a 128 kbps AAC source will sound identical whether played as AAC or as the converted AIFF. The benefit is editing flexibility, not quality improvement. File sizes will be approximately 10x larger than the AAC source (about 10 MB per minute for 16-bit/44.1 kHz stereo).
