Photos App Video Editor Error Can't View This File Type

If you’re using the Photos app on Windows or Mac and encounter the frustrating error message “Can’t View This File Type” when trying to edit or view videos, you’re not alone. This listicle covers the most common causes of this error and offers practical solutions for users of all levels—from casual editors to professional content creators—who want to troubleshoot and resolve video compatibility issues efficiently.

1. Unsupported Video Formats

The most frequent reason for the “Can’t View This File Type” error is that the video file is in a format not supported by the Photos app. For example, while MP4 and MOV files are generally compatible, formats like AVI, MKV, or FLV often cause issues. If your video is in an unsupported format, converting it to a more compatible one using tools like HandBrake or VLC Media Player can resolve the problem and allow seamless editing within the Photos app.

2. Corrupted Video Files

Corruption in the video file due to incomplete downloads, interrupted transfers, or storage errors can prevent the Photos app from recognizing or playing the video. Try opening the file in VLC Media Player; if it doesn’t play there, the file might be corrupted. Repair tools like Stellar Repair for Video or Remo Repair Video can often fix corrupt files, restoring their compatibility for editing.

3. Outdated Photos App or Operating System

Running outdated software can cause compatibility issues with newer video formats or codecs. Ensure your Windows or Mac operating system, as well as the Photos app, are fully updated. On Windows, check Windows Update, and on Mac, update via the App Store. Updated software includes bug fixes and improved codec support that can eliminate the “Can’t View This File Type” error.

4. Missing or Outdated Codecs

Codecs are essential for decoding video files. If your system lacks the necessary codecs, the Photos app may not recognize certain videos. Installing a comprehensive codec pack like K-Lite Codec Pack (Windows) or Perian (Mac) can add support for various formats. Be cautious to download codecs from reputable sources to avoid malware.

5. Insufficient Storage Space

Low storage space on your device can interfere with video processing and editing. When storage is nearly full, the Photos app may fail to load or process videos properly, resulting in errors. Free up space by deleting unnecessary files or moving videos to an external drive, then restart the app to see if the issue is resolved.

6. File Permissions and Security Settings

Sometimes, security settings or incorrect file permissions prevent the Photos app from accessing certain videos. Check the file properties on Windows or Get Info on Mac to ensure you have read and write permissions. Adjust permissions if necessary, and disable any security software that might be blocking access temporarily to test if it’s causing the error.

7. Conflicting Software or Background Processes

Other applications running in the background, such as antivirus software or video editing tools, can interfere with the Photos app’s ability to open videos. Try closing unnecessary programs and disabling real-time antivirus scanning temporarily. A clean boot on Windows or Safe Mode on Mac can help identify if background processes are causing the problem.

8. Large or High-Resolution Videos

Files with very high resolution or large file sizes may overwhelm the Photos app’s processing capabilities, leading to errors. If you’re working with 4K or 8K videos, consider downscaling them to 1080p or lower using video editing software before importing into Photos. This can improve performance and prevent the “Can’t View This File Type” error.

9. Hardware Limitations

Older computers or devices with limited RAM, CPU, or GPU may struggle to handle certain video formats or high-resolution files. Upgrading hardware components or optimizing system performance can help. Alternatively, using specialized video editing software like Adobe Premiere Pro or DaVinci Resolve might be more suitable for demanding files.

10. Reinstall or Reset the Photos App

If all else fails, reinstall the Photos app or reset its settings. On Windows, you can do this through the Settings app under Apps & Features, selecting Photos, and choosing Advanced options > Reset. On Mac, delete the Photos app from Applications and reinstall via the App Store. This can fix corrupted app files or misconfigurations causing the error.

How to Choose

When selecting a solution, consider the root cause of your problem. If your video format is unsupported, focus on conversion tools. For corrupted files, repair software is key. If software or system updates are needed, prioritize updating your OS and apps. Hardware limitations or large files may require hardware upgrades or file downscaling. Always back up your videos before attempting repairs or conversions to avoid data loss.
