Quality & Fidelity
Quality in this conversion depends primarily on your source file. A high-quality RMVB Video input produces an excellent MP4 Video output. Xonvert defaults to high quality settings that keep file size reasonable without compromising perceivable quality. RMVB Video encodes data using perceptual compression that prioritizes human perception. MP4 Video similarly focuses on perceptual quality. The conversion maps between these approaches intelligently. RMVB Video's known limitation — obsolete format with near-zero modern support — is resolved when converting to MP4 Video, which offers universal playback support with efficient H.264/H.265 compression.
Video format conversion from RMVB Video to MP4 Video involves re-encoding or remuxing the video stream. Xonvert selects the most efficient encoding strategy — remuxing when possible (zero quality loss) and re-encoding with optimal parameters when the target format requires a different codec. Key factors include codec compatibility, resolution handling, and audio stream preservation.
Resolution handling: Your video's original resolution is preserved by default. You can optionally downscale in the settings panel to reduce file size — useful when preparing content for mobile viewing or web upload.
