Technical Quality Assessment
Frame rate, resolution, and aspect ratio are maintained during conversion. Xonvert avoids unnecessary re-encoding when possible. When converting from FLV Video to MKV Video, some quality trade-off occurs due to lossy compression, but Xonvert uses optimal settings to minimize any visible degradation. FLV Video already discards some data during compression. Converting to MKV 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.
Video format conversion from FLV Video to MKV 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.
