Quality & Fidelity

Xonvert preserves embedded metadata (EXIF, XMP, ID3 tags, etc.) whenever the FLV Video format supports it. Format-exclusive metadata fields that have no equivalent in FLV Video are gracefully omitted without affecting the converted content. Quality in this conversion depends primarily on your source file. A high-quality F4V Video input produces an excellent FLV Video output. Xonvert defaults to high quality settings that keep file size reasonable without compromising perceivable quality. F4V Video encodes data using perceptual compression that prioritizes human perception. FLV Video similarly focuses on perceptual quality. The conversion maps between these approaches intelligently.

Video format conversion from F4V Video to FLV 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.
