Workflow

• Quick conversion: Right-click context menu for single files

• FFmpeg integration: Auto-detection, PATH support, and status verification window
• Advanced options: Format validation, transparency checks, configurable quality settings, automatic texture handling, file size estimates, optional subfolder organization

Benefits

• Save time with batch processing instead of manual conversions
• Maintain quality with professional conversion algorithms
• Organize assets with automatic subfolder creation
• Preview files before conversion with thumbnails and audio info
• Cancel operations at any time with progress tracking

How to Use

1. Single file: Right-click a supported asset in the Project window and pick a target from Convert > Image | Audio | Video > To …. Only the submenu matching the asset type is enabled. Selecting several assets converts them all.
2. Batch: Open Window > Converter Editor, add files, choose the output format and options, then run the conversion. Per-file progress and a completed / failed / cancelled summary are shown as it runs.
3. FFmpeg: Required for audio and video. Install it and put it on PATH; check detection with Window > Files Converter > FFmpeg Status.

Single-file conversion from the Project window: Convert > Video > To MP4.

Converter Editor running a batch: per-file progress, thumbnails, and a completed/failed/cancelled summary.

Settings

Edit > Project Settings > ManakhovN > File Converter:

• Quality (0.1–1.0): Shared quality factor for the conversion.
• Custom FFmpeg Path: Override auto-detection. The panel shows the current detection status and warns when FFmpeg is missing.
• Audio Bitrate, Video Bitrate, Default Width / Height / Frame Rate: Defaults handed to FFmpeg.
• Preserve Aspect Ratio: Image resizing behaviour.
• Create Backup, Delete Originals, Output Folder Name: What happens to the source file and where the result lands.

Technical Specs

• Unity: 2020.3+
• Editor-only: No runtime overhead
• Processing: Asynchronous with progress reporting
• UI: UIElements-based interface
• Assembly: Assembly definition support

Requirements

• Unity Editor 2020.3+
• FFmpeg installation required for audio and video conversion (images may use built-in Unity conversion where applicable)
• Tested on Windows; other platforms may require FFmpeg in PATH

Tips & Best Practices

• Install FFmpeg and add it to your system PATH for full audio/video support.
• Use batch mode for large sets of assets; preview thumbnails help verify selection.
• Adjust quality presets and output formats per platform (e.g., mobile vs. desktop).
• Use subfolder organization to keep converted assets tidy.

Troubleshooting

• Conversion fails: Verify FFmpeg is installed and in PATH for audio/video; check file permissions and disk space.
• No preview: Ensure file format is supported; check Unity import settings for textures.
• Slow batch runs: Large video files take longer; use progress tracking and cancel if needed.
