Quality & Fidelity

AU Audio retains all original data. Converting to MOV Video applies its own compression algorithm, which may introduce minor artifacts at very low quality settings. Xonvert selects parameters that maximize quality for the target format. For professional use, quality assurance is critical. Xonvert's AU Audio to MOV Video pipeline has been tested against reference implementations to ensure output meets video industry standards. Real-world quality depends on three factors: source file quality, format capabilities, and encoder settings. Xonvert optimizes the third factor automatically, but starting with the best possible AU Audio source always yields the best MOV Video output.

Converting AU Audio audio to MOV Video video creates a video file with a static visual (typically a black frame or waveform visualization) and your audio track. This is commonly used for uploading music to video-only platforms like YouTube, creating visualizer content, or embedding audio in video projects.

Compression trade-off: Your lossless AU source retains all original data. Converting to lossy MOV will reduce file size substantially, but some data is permanently discarded. Use the quality slider to balance file size against fidelity.
