QuickTime vs Opus: Format Comparison

Key differences between the two formats

Feature	MOV (QuickTime)	Opus
Type	Apple proprietary video container	Open audio codec in OGG container
Developer	Apple Computer	Xiph.Org / IETF RFC 6716
Audio codec	AAC, PCM, or ALAC	Opus — state-of-the-art open codec
File size	Large (video included)	Very small — highly efficient compression
Latency	Standard playback latency	Ultra-low latency (as low as 5ms)
License	Proprietary	Open-source, royalty-free
Quality at low bitrate	Degrades significantly	Excellent even at 64 kbps
Use case	Apple video production	WebRTC, Discord, streaming, VoIP applications

When to Convert

Common scenarios where this conversion is useful

Extract iPhone video audio for Discord bot playback

Discord's audio infrastructure uses Opus. If you recorded audio on an iPhone as a MOV video, extract it to Opus to feed it into a Discord bot audio stream with native Opus support and minimal processing.

Create compact audio from Final Cut Pro exports

Final Cut Pro exports MOV files. If you only need the audio from an export — narration, music, dialogue — Opus provides an exceptionally compact file at high quality, ideal for web distribution.

Prepare QuickTime audio for WebRTC applications

WebRTC uses Opus for audio transmission. Converting MOV video audio to Opus lets you integrate pre-recorded Apple content into WebRTC-based streaming tools, browser apps, or real-time communication platforms.

Compress iPhone video audio for low-bandwidth sharing

Opus delivers excellent quality at just 32–64 kbps — a fraction of what AAC needs for equivalent quality. Extract MOV audio to Opus for ultra-compact audio sharing over slow connections or in data-sensitive environments.

Build open-format audio from Apple video sources

Opus is royalty-free and supported on all major open platforms. Convert Apple MOV audio to Opus to use in open-source projects, Linux servers, or Icecast streaming infrastructure without licensing concerns.

How to Convert QuickTime to Opus

1

Upload your MOV file

Drag and drop your .mov file onto the converter or click to browse and select it. Files up to 500MB are supported.
2

Server-side Opus encoding

Your MOV file is uploaded over HTTPS and FFmpeg extracts and decodes the audio stream, encoding it as Opus in an OGG container. The video track is discarded entirely. Processing typically takes just seconds.
3

Download your Opus file

Click Download to save the .opus file. Both the original MOV and the Opus output are automatically deleted from our servers after download.

Frequently Asked Questions

What makes Opus better than AAC for streaming?

Opus is designed specifically for streaming and real-time communication. It supports ultra-low latency, outperforms AAC at bitrates below 128 kbps, and is fully open-source. For streaming applications, Opus is increasingly the preferred choice over AAC.

Will the MOV audio lose quality when converted to Opus?

Opus is a lossy codec, so some quality is lost during encoding. At high target bitrates (128 kbps+), Opus quality is considered transparent for most listeners. The quality ceiling is set by the source audio in the MOV.

What file extension does the Opus output use?

Opus audio files use the .opus extension (or .ogg on some systems). The OGG container holds the Opus audio stream, and .opus is the RFC 7845-specified extension for Opus-in-OGG files.

Does Opus work in Safari on iOS?

Safari added Opus support in version 16.0 (iOS 16, macOS Ventura). For older Safari versions, AAC or MP3 are more compatible choices. Modern browsers including Chrome, Firefox, and Edge have supported Opus for years.

Can I use Opus audio in Discord bots?

Yes. Discord uses Opus internally for all voice audio. Python (discord.py with PyNaCl) and Node.js (discord.js with @discordjs/opus) support native Opus playback, making converted .opus files ideal for bot audio.

How small is an Opus file from a MOV source?

Opus at 128 kbps produces approximately 1MB per minute of audio. A 60-minute MOV recording converted to 128 kbps Opus audio produces roughly 60MB — a tiny fraction of the original MOV file size.

Does Opus support surround sound?

Yes. Opus supports multi-channel audio including 5.1 and 7.1 configurations. If your MOV contains surround audio, FFmpeg will preserve the channel layout in the Opus output.

Is this tool free?

Yes. ChangeThisFile is completely free with no signup and no conversion limits. Opus is also royalty-free — no licensing costs at any stage.

How fast is MOV to Opus conversion?

Very fast. Opus encoding is computationally efficient. A one-hour MOV video typically converts to Opus in under 30 seconds on our servers.

Are uploaded MOV files secure?

Yes. All uploads are encrypted via HTTPS. Files are automatically deleted from our servers immediately after you download the Opus file. We never retain or access your content.
