Opus conversion FAQ

What is a Opus file?

Opus is Apple's QuickTime video container format. Developed by Apple, MOV files are commonly used by iPhones, iPads, and Mac computers. MOV supports high-quality video, multiple audio tracks, subtitles, and is widely used in professional video editing.

How do I convert Opus files?

Upload your MOV file using drag-and-drop or click to browse. Select your output format (MP4, AVI, WebM, etc.), adjust quality settings if needed, and click Convert. Your video will be converted quickly while maintaining quality.

Is the video conversion free?

Yes, our MOV converter is free for basic use. Convert iPhone and Mac videos without registration. Premium features are available for larger files and advanced video editing options.

What's the difference between MOV and MP4?

MOV and MP4 are closely related formats that can contain similar video codecs. MOV is Apple's native format optimized for QuickTime. MP4 is more universally compatible across devices. For sharing videos recorded on iPhone or edited on Mac, converting MOV to MP4 ensures broader compatibility.

How do I convert iPhone videos?

iPhone videos recorded in MOV or HEVC format can be uploaded directly to our converter. We support all iPhone video formats including 4K and HDR content. Convert to MP4 for universal compatibility or WebM for web use while preserving video quality.

Do you support HEVC MOV files?

Yes! We fully support HEVC (H.265) encoded MOV files, which are standard for newer iPhones and iPads. HEVC provides excellent quality at smaller file sizes. We can convert HEVC to H.264 for broader compatibility or maintain HEVC in the output.

Why can't I play MOV files on Windows?

Windows doesn't natively support all MOV codecs, especially ProRes or HEVC. Converting MOV to MP4 solves playback issues on Windows PCs. Alternatively, install the HEVC extension from Microsoft Store or use VLC media player for direct playback.

Will I lose quality when converting MOV?

Our converter uses high-quality settings by default to minimize any quality loss. You can also choose higher quality/bitrate settings. For the best results with minimal loss, we use two-pass encoding which analyzes the video first for optimal compression.

Can I convert Apple ProRes MOV files?

Yes, we support ProRes MOV files commonly used in professional video production (Final Cut Pro, DaVinci Resolve). ProRes files are large but high quality. We can convert them to more compressed formats for sharing while preserving as much quality as possible.

What's the maximum MOV file size?

Free users can convert MOV files up to 500MB, suitable for most iPhone videos and short clips. Premium users have access to larger file limits for 4K videos, long recordings, or professional ProRes footage. Large files take more time to process.
