What to know about RMVB
Media container
RMVB can hold encoded video and one or more audio tracks.
Audio extraction
Conversion to MP3 keeps the selected audio content and removes the video stream.
Codec support
Successful decoding depends on the codecs stored inside the container.
File size
Video sources are usually much larger than the extracted audio result.
How RMVB conversion works
Converting RMVB decodes the source audio and encodes it with the destination format's codec and selected quality settings.
Lossy conversion cannot restore detail already removed from the source, so keep the original when quality matters.
mp3.now accepts RMVB as an input and converts its audio to MP3.
RMVB compatibility and software support
Playback support for RMVB depends on the device, browser, container features and codecs inside the file.
MP3 output is broadly supported by phones, computers, browsers, editors and media players.
