Symptoms: OpenShot crashes unexpectedly or freezes during video export
Root Causes: Preferences corruption / encoder parameter conflicts, GPU hardware acceleration instability, output path issues
Solution: Reset OpenShot preferences → Clear temp files → Disable GPU acceleration → Use English-only export paths
Quick Start (≈2 minutes)
- Close OpenShot completely and delete OpenShot-related files in temp folder (
%temp%) - Reset OpenShot preferences to default (delete
C:\Users\<USERNAME>\.openshot_qt\) - Disable hardware acceleration in Preferences
- Set export path to a simple English folder name
- Save project with a new name and retry export
Understanding OpenShot Export Crashes
OpenShot Video Editor is a popular free, open-source video editing program. However, users frequently encounter crashes or freezes during the export process. These issues are particularly common when working with high-resolution (4K) videos or when GPU acceleration is enabled.
Main Causes of OpenShot Export Errors
Export crashes generally fall into three categories: encoder configuration issues, GPU acceleration conflicts, and file path recognition errors. Each cause presents different symptoms, making accurate diagnosis essential.
Common Issues Reported by Users
Analysis of the OpenShot community forums and GitHub issue tracker reveals that crashes following preference corruption and path errors caused by non-ASCII folder names are among the most frequently reported problems. Stability with GPU acceleration varies by driver and GPU model, so testing with acceleration off is a reliable first step.
Detailed Comparative Analysis by Cause
| Crash Cause | Detailed Explanation | Recommended Solution |
|---|---|---|
| Preferences / Encoder Options | Encoding may fail due to corrupted settings or mismatched encoder parameters | Delete the OpenShot preferences folder to restore defaults |
| GPU Hardware Acceleration Conflict | Compatibility issues between the renderer and graphics driver can cause forced termination | Disable hardware acceleration in Preferences |
| Output Path Recognition Failure | On some systems, non-ASCII/special characters in paths can trigger permission or write errors | Use a simple ASCII path (e.g., C:\Export\) and retry |
| Accumulated Temporary Files | Residual files in the system TEMP folder reduce free space or collide with new renders | Clean %temp% folder |
Step-by-Step Crash Resolution Guide
Step 1: Reset OpenShot Preferences
When OpenShot preferences become corrupted or store incorrect encoder parameters, crashes can occur during export.
- Ensure OpenShot is completely closed
- Open File Explorer and go to
C:\Users\<USERNAME>\.openshot_qt\ - Delete this folder (you may back it up first) to force a full settings reset
- Relaunch OpenShot; default settings will be recreated automatically
- Test export with a short video clip to verify proper operation
Step 2: Disable GPU Hardware Acceleration
Note: GPU acceleration is experimental and may be unstable depending on drivers and hardware. Turning it off is a safe baseline for troubleshooting.
- Select Edit → Preferences from OpenShot's top menu
- Navigate to Preferences → Performance tab
- Set Hardware Decoder Mode to CPU (No acceleration)
- If a Hardware Encoder option is present, set it to CPU/None as well
- Save settings and completely restart the program
- Retry export
Step 3: Reconfigure Output Path
On some systems, non-ASCII characters, special characters, or spaces in file paths can cause write or permission errors.
- In the export dialog, specify a simple ASCII path like
C:\ExportTest\ - Use only English letters and numbers for filename (e.g., output_video_001.mp4)
- Recommended: MP4 container with H.264 codec
- Keep resolution and frame rate consistent with original project settings
Step 4: Clean System Temporary Files
OpenShot generates large amounts of temporary files during rendering, and their accumulation can cause disk space errors.
- Type
%temp%in Windows Run dialog (Win + R) - Delete all OpenShot-related folders and files
- Empty Recycle Bin for complete deletion
- Optional: In Preferences → Cache, lower the Disk Cache or switch to a Memory-based cache if available
Step 5: Resave Project File
If the project file (.osp) is corrupted, export may not proceed normally.
- Select "Save As" from File menu
- Save project with a new filename
- Retry export with the newly saved project file
Exception Cases and Important Notes
If your project (.osp) file is severely corrupted, look for backup files or reimport media files into a new project and rebuild the timeline. OpenShot has an auto-save feature, so check the
C:\Users\<USERNAME>\.openshot_qt\recovery folder. You can also restore from backups via File → Recovery.

Frequently Asked Questions
Export progress stuck at 0% and won't move?
Check write permissions for the output folder. Avoid C:\ root or Program Files as they may have permission issues—use Documents or a dedicated folder instead. Also verify system TEMP space and available disk space.
Still crashing even after disabling GPU acceleration?
Test with a short clip in a new project. If problems persist, consider reinstalling OpenShot or replacing FFmpeg with a stable version.
Export speed is extremely slow—any way to improve it?
Lower project resolution (4K→1080p) or set output quality to Fast. Minimize effects and transitions. Once stability is confirmed, you can reconsider enabling GPU acceleration.
Final Troubleshooting Checklist
- Have you deleted the OpenShot preferences folder to reset to defaults?
- Is GPU hardware acceleration completely disabled in Preferences (decoder—and encoder, if present)?
- Is your export output path set to English-only with no special characters?
- Have you cleaned the system temp folder (
%temp%)? - Do you have at least 10GB of free disk space?
- Have you verified export works with a short test video?
- Have you saved the project with a new name and retried?
Additional FAQ
Is it safe to manually update FFmpeg?
Yes, but make sure to use an FFmpeg build compatible with your OpenShot version. Download the officially recommended version and replace the existing executable for best results.
Will exporting in a different format reduce crashes?
It depends on your environment. Generally, MP4 (H.264) is the most stable format. WebM is an alternative, but MP4 offers better overall compatibility.
Are there alternative free video editing programs?
DaVinci Resolve (free version) and Shotcut are solid alternatives with strong reputations for features and stability, though they have steeper learning curves than OpenShot.
