Why Convert Xvid to Opus?
Xvid is an open-source MPEG-4 ASP video codec popular for sharing movies in the 2000s. Opus is a modern, royalty-free audio codec that delivers the same quality as MP3 at roughly half the file size. Converting Xvid to Opus extracts the audio track and re-encodes it with Opus, which is useful for saving movie soundtracks or dialogue as compact audio files, extracting audio for podcasts or voice-over use, creating lightweight audio files for web and streaming applications, and listening to video content on audio-only devices with minimal storage.

Why is Opus better than MP3 for audio extraction?
Opus delivers equivalent quality at roughly half the bitrate of MP3. A 64 kbps Opus file sounds comparable to a 128 kbps MP3. This means smaller files with the same perceived quality — ideal for streaming and storage-constrained use cases.
What bitrate should I use?
Xvid files typically contain MP3 audio at 128-192 kbps. Extract at 64-96 kbps Opus for equivalent quality in a smaller file. For voice/dialogue content, 32-48 kbps Opus is sufficient.
Can I trim the audio during conversion?
Yes. Under Trim, switch to "Trim" and enter a Start Time and Duration. This extracts audio from a specific scene without separate editing software.
Does this tool accept .avi files with Xvid codec?
This tool accepts .xvid files specifically. If your Xvid video has an .avi extension, use AVI to Opus instead.
What players support Opus files?
VLC, foobar2000, Firefox, Chrome, Edge, and most modern media players support Opus. Android supports Opus natively since Android 5.0. iOS/Safari added Opus support in iOS 17.
