The codec to encode the audio track. Codec "Without reencoding" copies the audio stream from the input file into output without re-encoding if possible.
Set the Vorbis encoder audio quality level. The scale is non-linear. The "Auto" mode produces roughly 112 kbps bitrate and is good in most cases.
Set the number of audio channels. This setting is most useful when downmixing channels (e.g., from 5.1 to stereo).

rmvb

RMVB (RealMedia Variable Bitrate) is an enhanced version of the RealMedia container format developed by RealNetworks, introduced around 2003. While the original RM format used constant bit rate encoding, RMVB employs variable bit rate compression that dynamically allocates more data to complex scenes with high motion and detail, and fewer bits to simpler passages like static shots or fade transitions. This approach yields significantly better visual quality at equivalent average file sizes compared to the constant bit rate predecessor. RMVB gained particular popularity in East and Southeast Asian markets during the mid-2000s, becoming a widely used format for distributing full-length movies and television content in regions where bandwidth was limited but viewers still demanded reasonable picture quality. The format typically uses RealVideo 9 or RealVideo 10 codecs, which drew on technologies comparable to H.264 in their compression approach. RMVB files support embedded subtitle streams and multiple audio tracks, making them practical for multilingual content distribution. The container retains the streaming-friendly architecture of RealMedia while delivering the quality improvements that variable bit rate encoding provides. Although RMVB has been superseded by MP4 with H.264 and other modern formats for most purposes, it retains a user base in Asian markets and can still be found in online media archives and personal video collections from the mid-2000s era.

ogg

OGG Vorbis is an open, royalty-free lossy audio codec inside the Ogg container format, both developed by the Xiph.Org Foundation. Vorbis was designed as a patent-free alternative to MP3 and AAC, using modified discrete cosine transform (MDCT) coding with variable bitrate encoding that adapts to signal complexity per frame. Blind listening tests have consistently shown Vorbis delivering perceptual quality matching or exceeding MP3, especially in the 96-192 kbps range. The format supports sample rates from 8 kHz to 192 kHz and 1 to 255 channels, covering everything from mono voice to surround mixes. A standout advantage is the complete absence of licensing fees — game developers, streaming platforms, and hardware makers can implement Vorbis without royalty concerns. Spotify relied on Vorbis for years as its primary streaming codec for exactly this reason. The format also handles quality degradation at low bitrates more gracefully than many competitors, which is why it remains popular in video games where storage is tight and thousands of sound effects compete for space. VLC, Firefox, Chrome, and Android all provide native Vorbis decoding.

Frequently Asked Questions

Why convert RMVB to OGG?

OGG Vorbis is royalty-free and delivers quality comparable to AAC. Extracting RMVB audio into OGG frees it from the proprietary RealMedia ecosystem.

What applications play OGG files?

VLC, foobar2000, Firefox, Chrome, most Linux players, and Android devices handle OGG natively. Windows users can play OGG via VLC or codec packs.

Does OGG Vorbis sound better than MP3?

Generally yes — OGG Vorbis produces cleaner audio than MP3 at equivalent bitrates, especially in the 96-192 kbps range where the gap is most audible.

Can I adjust quality when converting RMVB to OGG?

Yes — set the bitrate and quality level before conversion to balance file size against fidelity. Settings are available on the conversion page.

Are my RMVB uploads kept on servers?

No. RMVB files are deleted immediately after audio extraction. OGG output files are automatically purged within 24 hours for your privacy.
