Supports: DIVX
This tool pulls the soundtrack out of a DivX video and saves it as a standalone Opus file — the picture is discarded and only the audio is kept. It is built for modernizing early-2000s DivX rips (the AVI-era movies that fit a feature onto a single CD) into Opus, the royalty-free codec the web, messaging apps, and streaming services now lean on. The honest catch: DivX clips almost always carry MP3 or AC-3 audio, both already lossy, so Opus shrinks the file efficiently but cannot rebuild detail the original encode threw away.

No. This is an audio extraction: the DivX video track is discarded and you get an audio-only .opus file. DivX is a brand of MPEG-4 Part 2 (ASP) compression from the early-2000s AVI ripping era, and this tool keeps only its soundtrack. If you want to keep the picture in a modern format instead, convert the whole clip to DivX to MP4.
No — and that is an honest limit, not a tool flaw. DivX files in AVI almost always carry MP3 or AC-3 (Dolby Digital) audio, both already lossy, so re-encoding to Opus is a lossy-to-lossy transcode that cannot regain detail the original codec discarded. The real win is efficiency: Opus packs the same perceived quality into a much smaller, modern file. Pick a bitrate at or near the source to avoid adding noticeable new loss — pushing it far higher just makes a bigger file.
It depends on the Audio Channel setting. Many ripped DivX movies carry a 5.1 AC-3 track; leave Audio Channel on Original to preserve the multichannel layout, or set it to a stereo downmix if your playback target is headphones or a phone. In our testing, a 384 kbps 5.1 AC-3 track from a DVD rip downmixed cleanly to a 160 kbps stereo Opus file with no audible folding artifacts in normal listening. If you need every discrete channel intact for a home-theater setup, keep it on Original.
Less than you would expect, because Opus is very efficient. For a stereo MP3 source around 128–192 kbps, Opus at 96–128 kbps is already transparent for most listeners — Opus reaches at 96 kbps roughly what MP3 needs 128 kbps for. For AC-3 DVD audio at 192–384 kbps, 128–160 kbps Opus comfortably preserves a stereo mix. For speech-only clips, 32–64 kbps mono stays clean and tiny. If you would rather aim at a file-size target, use Specific file size and let the encoder pick the bitrate.
Usually on phones, less reliably on older car and TV hardware. Chrome, Firefox, and Edge play Opus; Safari support is only partial, so an .opus file may not play directly in it. Android has recognized the bare .opus extension since Android 10 (earlier versions play it inside .ogg or .mkv). The weak spots are a long tail of pre-2018 devices — some legacy car infotainment systems and older smart TVs never added Opus. If you need guaranteed playback on old hardware, extract to DivX to MP3 for universal compatibility, or DivX to AAC for better-than-MP3 efficiency that Apple devices handle natively. Opus is standardized by the IETF as RFC 6716 (September 2012), combines the SILK and CELT engines, and is royalty-free — a genuinely good modernization target when the device supports it.
Your DivX file is uploaded over an encrypted (TLS) connection, processed on our servers, and deleted automatically a few hours after conversion. There is no sign-up, no watermark on the output, and your files are never shared or made public.
