Possible causes and solutions

- Damaged or empty MOV files

Check the file size of the MOV file you can't open. A video with only a few kb may refuse to process. Test the MOV video with other players or video processing programs to see if it's corrupted. If your media player or editor can open other MOV sources, the issue is with the MOV file. Follow the guide to repairing corrupted MOV videos.

- Format incompatibility

MOV is a container format and can be encoded with different codecs that may be not accepted by your program or operating system. Many devices capture HEVC MOV footages, such as iPhone 7 or later running iOS 11 or later, DJI Phantom 4 Pro, Mavic 2 Pro/Zoom, and many more. HEVC video viewing and editing require macOS High Sierra or later. The support for HEVC codec was removed from Windows 10 Fall Creators Update. MOV HEVC video processing in Premiere Pro CC requires version 12.0.1 or later. HitFilm currently doesn't include the ability to decode MOV HEVC footages. To fix the issue,

- Update your operating system.
- Update your video editor or media player to the latest version.
- Install MOV codec and HEVC codec pack on your computer.
- Transcode MOV to MP4 format, or HEVC to H.264 format that is universally accepted.

- Clear media cache. When importing files, your program processes versions of these files for faster access. Theses are media cache files that store in the media cache database. Cache data can slow down your workflow. Try clearing the media cache of the media player and video editor, and import your MOV clips again.

MOV Files Won't Play Properly - No Sound, V/A out of Sync, Freezing

No Sound with Imported .mov Videos

Some users reported they were able to play and edit .mov files but there is no sound. Video is fine, no error message pops up. Try playing other video files to see if they have audio. Use another media player to play the MOV video file. Make sure the volume and sound settings are correct. Check the speakers and install the latest sound driver. The incompatible audio codec can also cause the MOV audio missing issue. Learn more solutions to no sound on MOV videos.

MOV Video and Audio out of Sync

The MOV video doesn't match the audio after importing to VLC, QuickTime, Windows Media Player, Adobe Premiere Pro, and other programs. Causes of the error may be corrupted media files, improper settings, a variable frame rate that your video processing software like Adobe Premiere Pro can't handle, to name a few. For more reasons and fixes, check what to do when MOV video and audio are out of sync.

MOV Video Freezing/Stuttering/Choppy/Laggy

MOV file playback stutters, the image lags behind the sound, particularly MOV video in high resolution (4K UHD) and mov video with HEVC codec. The problem happens in VLC, QuickTime Player, Adobe Premiere Pro, and other players and video editors. Large 4K Ultra HD MOV video processing requires powerful enough CPU and hardware. If your MOV video uses the HEVC codec, it has a higher CPU overhead than others. The following ways may be helpful.

Convert HEVC codec to H.264 format that is widely compatible and uses less CPU power.
Compress large 4K UHD MOV footages by changing 4K to 1080p, trimming, lowering down bit rate, etc.
Use video processing programs with hardware acceleration.
