How M4V Handles AU Data
Dynamic range — the span from darkest to brightest values — is handled carefully during this conversion. AU Audio preserves the full range. M4V Video optimizes for typical display capabilities. Xonvert preserves embedded metadata (EXIF, XMP, ID3 tags, etc.) whenever the M4V Video format supports it. Format-exclusive metadata fields that have no equivalent in M4V Video are gracefully omitted without affecting the converted content. Quality in this conversion depends primarily on your source file. A high-quality AU Audio input produces an excellent M4V Video output. Xonvert defaults to high quality settings that keep file size reasonable without compromising perceivable quality.
Converting AU Audio audio to M4V 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 M4V will reduce file size substantially, but some data is permanently discarded. Use the quality slider to balance file size against fidelity.
