Fidelity When Converting MP4 to AIFF
Frame rate, resolution, and aspect ratio are maintained during conversion. Xonvert avoids unnecessary re-encoding when possible. When converting from MP4 Video to AIFF Audio, the conversion is lossless, meaning every bit of data is preserved exactly as in the original. MP4 Video already discards some data during compression. Converting to AIFF Audio adds no further quality degradation since it uses lossless compression. Xonvert selects parameters that maximize quality for the target format.
Extracting audio from MP4 Video video to AIFF Audio format strips the video track and saves only the audio content. This is perfect for extracting music from music videos, saving podcast audio from video recordings, or creating audio-only versions of lectures and presentations. The audio quality depends on the original video's audio track bitrate and codec.
Important: Converting from lossy MP4 to lossless AIFF does not restore previously discarded data. The output perfectly preserves your current file quality without adding further degradation, but quality lost during the original MP4 encoding cannot be recovered.
