Why should I convert RMVB files to MKV?

RMVB is a proprietary RealMedia format with limited support on modern devices. MKV is an open, flexible container that holds various codecs like H.264/HEVC and supports subtitles. Converting to MKV improves playback compatibility on Smart TVs, gaming consoles, and media players, and can reduce file size when using efficient codecs.

What happens to video and audio quality when converting RMVB to MKV?

LetsConvert re-encodes RMVB video tracks to H.264/HEVC and audio to AAC, preserving the original resolution and frame rate. Since RMVB is lossy, the re-encode introduces generational loss, but you can minimize it by setting a high bitrate or a constant quality factor (e.g., CRF 18). Subtitles and metadata are preserved if present in the source.
