How RM Handles AU Data
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 RealMedia Video output. Supports mu-law, A-law and linear PCM encoding When this data is re-encoded into RealMedia Video, Used RealVideo codec optimized for dial-up connections (28-56 kbps) Xonvert accounts for these differences to maintain visual and structural integrity. Color accuracy is a priority in this conversion. Xonvert maintains data integrity across the format boundary. The output closely matches your original.
Converting AU Audio audio to RealMedia 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 RM will reduce file size substantially, but some data is permanently discarded. Use the quality slider to balance file size against fidelity.
