Ever tried opening an MTS file in QuickTime only to see an error or a blank screen? You’re not alone. Many users encounter compatibility issues when trying to play MTS (AVCHD) files from camcorders and cameras on their Mac. Fortunately, there are straightforward solutions that will have your videos playing in QuickTime in no time at all. This guide walks you through the simplest, most reliable methods to convert MTS files to MOV.

Why Can’t QuickTime Play MTS Files?

MTS is a video format used primarily by digital camcorders. While this format excels for capturing high-quality AVCHD footage, it doesn’t always play nicely with QuickTime, especially on macOS. QuickTime’s preferred video container is MOV, which works seamlessly for both playback and editing on Apple devices.

Common MTS Playback Issues on Mac

• QuickTime Player won’t recognize or open MTS files.
• Video plays without sound, or vice versa.
• Editing MTS clips in iMovie or Final Cut results in crashing or degraded quality.

The fix? Convert MTS to MOV. This ensures your files become instantly compatible with Mac software, eliminate choppy playback, and unlock easy video editing.

Tips for High-Quality Video Conversion

Keeping your memories crisp and clear matters, especially for footage shot on camcorders. Here’s how to get the best results:

• Select Highest Output Quality: Always pick the highest quality or “lossless” option available to preserve detail.
• Keep Audio and Subtitles: Some converters allow the option to retain original audio tracks or subtitles. Look for these settings if your file has more than one.
• Batch Convert to Save Time: If converting many files, use a tool that supports batch processing to avoid repetitive work.
• Preview the File Before Deleting Originals: Always double-check your converted files for missing audio, distorted images, or playback issues before removing your MTS originals.

MOV Versus MP4

While MOV and MP4 are often interchangeable, MOV is Apple’s proprietary format and includes more features for pro editing on Macs. If you only need playback, MP4 works too, but MOV is best for editing and seamless QuickTime compatibility.

Troubleshooting Common Conversion Issues

Sometimes conversions don’t go as planned. Here’s how to fix the most common speedbumps:

Video Won’t Play After Conversion

• Double-check the converted MOV by opening in QuickTime and VLC.
• Try re-exporting with different codec/quality settings.
• Make sure you aren’t converting DRM-protected content.

Audio Sync Issues

• Test conversion with different audio codecs (AAC typically works well for MOV files).
• Use updated versions of your chosen tool.
• Batch processing? Check if only some files have a problem—conversion can occasionally hiccup.

Large File Size

• Compress with a professional converter’s built-in options if storage is an issue.
• For uploading or sharing, consider exporting in 1080p instead of 4K (if not needed).

Conclusion

Converting MTS to MOV means you’ll never face playback issues on your Mac again. Choose the method that’s best for your needs, and you’ll unlock smooth QuickTime playback, hassle-free editing in iMovie, and easy archiving of your video memories. Whether you’re a tech pro or new to video files, a smooth experience is just a few clicks away.
