About RMVB files
RMVB (RealMedia Variable Bitrate) is a video file format developed by RealNetworks as an extension of the RM format. It uses variable bitrate compression to improve video quality while keeping file sizes relatively small. RMVB was widely used for online video distribution in the past. Today, it is considered a legacy format with limited support on modern media players and platforms.
About MKA files
MKA (Matroska Audio) is an audio container format based on the Matroska multimedia framework. It supports various audio codecs (e.g., FLAC, AAC, Opus) and features like multiple audio tracks, chapters, and metadata. Primarily used for high-quality audio storage and playback, it offers flexibility similar to MKV but focuses solely on audio content.

Additional Settings:

  • Output Dimension: Set the width and height for the output MKA file.
