Notes

• All scripts require PowerShell 7+ (use pwsh.exe)
• File extensions (.mp4, .png) are automatically added if not provided
• Paths can be absolute or relative to current directory
• Use .skip.mp4 extension to exclude files from batch processing
• Backup files (.bak.mp4) are automatically skipped in batch operations

Troubleshooting

Error: "Video file not found"

• Check that the file path is correct
• Ensure file exists at specified location
• Use absolute paths if relative paths aren't working

Error: "ffmpeg failed" or "ffprobe failed"

• Verify ffmpeg and ffprobe are installed and in PATH
• Check that the video file is not corrupted
• Ensure sufficient disk space for output

Error: "Frame index out of range"

• Use Get-FramesCount.ps1 to check valid frame range
• Frame indices are 0-based (first frame is 0)
