Installation

Step 1: Install FFmpeg

1. Visit https://ffmpeg.org/download.html
2. Download the appropriate version for Windows
3. Extract to a folder (e.g., C:\ffmpeg)
4. Add FFmpeg to your system PATH:
   • Press Windows Key + X and select "System"
   • Click "Advanced system settings"
   • Click "Environment Variables"
   • Under "System variables", select "Path" and click "Edit"
   • Click "New" and add the FFmpeg folder path
   • Click OK and restart your computer

Step 2: Download the Script

1. Clone or download movie_converter720_v2.bat from this repository
2. Place it in a folder where you have write permissions

Step 3: Prepare Your Videos

1. Copy all video files you want to convert to the same directory as the batch script
2. Supported formats: .mkv, .mp4, .avi

Usage

Running the Script

1. Open Command Prompt or PowerShell
2. Navigate to the directory containing movie_converter720_v2.bat
3. Run: movie_converter720_v2.bat
4. Follow the on-screen prompts

Step-by-Step Guide

1. Select Language

1. English
2. Español
3. Italiano

Choose your preferred language (prompts and messages will display in this language).

2. Select Encoder

1. Generic (libx265 - Software)
2. Intel QuickSync (Fast, if available)
3. NVIDIA NVENC (Fast GPU, if available)
4. AMD VCE (Fast GPU, if available)

Choose based on your hardware. The script will auto-detect availability and fall back to libx265 if your chosen encoder isn't available.

3. Select Resolution

1. 480p  - Small file, mobile/streaming
2. 720p  - Standard, good for most uses
3. 1080p - Full HD, recommended
4. 1440p - QHD, high quality
5. 2160p - 4K, highest quality

Or enter a custom resolution (e.g., 1440).

4. Select Quality

1. Low (17-22)      - Small file, lower quality
2. Medium (23-25)   - Balanced size and quality
3. High (26-28)     - Larger file, better quality
4. Ultra (29+)      - Very large file, excellent quality
5. Custom (0-51)    - Enter your own CRF value

Quality Scale (CRF - Constant Rate Factor):

• Lower values = Better quality, larger file size
• Higher values = Smaller file size, lower quality
• Range: 0-51 (0 = lossless, 51 = lowest quality)
• Recommendation: 23-27 for most use cases

Conversion Process

Once you've selected your options:

1. The script detects all video files in the current directory
2. For each file, it:
   • Checks for Italian audio tracks (uses Italian if available)
   • Checks for Italian subtitle tracks
   • Displays file information and progress
   • Converts using your selected encoder and settings
3. Successfully converted files are saved to Converted_[RESOLUTION]/
4. Failed conversions are copied to Converted_errors/ for troubleshooting

Example Output Structure

Original Directory:
├── movie_converter720_v2.bat
├── video1.mkv
├── video2.mp4
└── video3.avi

After Conversion:
├── Converted_720p/
│   ├── video1.mkv
│   ├── video2.mkv
│   └── video3.mkv
└── Converted_errors/
    └── (any failed files)

Performance Tips

For Best Speed:

• Use GPU acceleration (Intel QuickSync/NVIDIA NVENC/AMD VCE) if available
• Lower the quality setting (higher CRF values)
• Reduce resolution
• Ensure FFmpeg has enough system resources available

For Best Quality:

• Use higher resolution (1080p or 1440p)
• Use lower quality values (CRF 23-25)
• Use generic libx265 if you have time (slightly better quality than GPU encoders)

Storage Considerations:

• 480p low quality: ~200-400 MB per hour
• 720p medium quality: ~400-800 MB per hour
• 1080p high quality: ~1-2 GB per hour
• 1440p ultra quality: ~2-4 GB per hour

Troubleshooting

FFmpeg Not Found

Error: FFmpeg not found in PATH!

• Solution: Verify FFmpeg installation and PATH configuration
• Download from: https://ffmpeg.org/download.html
• Add FFmpeg folder to system PATH and restart your computer

Encoder Not Available

Message: [Encoder] not available, falling back to libx265...

• Cause: Your hardware doesn't support the selected GPU encoder
• Solution: This is normal and handled automatically. Conversion will proceed with libx265
• To use GPU acceleration, ensure your GPU drivers are up to date

Conversion Fails

Error: Conversion failed - [filename]

• Solutions:
  1. Check if the video file is corrupted: ffmpeg -i "filename" -f null NUL
  2. Try a different encoder
  3. Try a lower quality setting
  4. Ensure sufficient disk space
  5. Check system resources (CPU/RAM)

Permission Denied

Error: Access is denied

• Solution: Run Command Prompt as Administrator
• Right-click Command Prompt and select "Run as administrator"

Character Encoding Issues

Issue: Non-ASCII characters display incorrectly

• Solution: This can happen with certain filenames
• Rename files to use ASCII characters only
• Or run in a UTF-8 capable terminal

Video Format Support

Input Formats

• .mkv (Matroska) - Recommended, best support for audio/subtitle detection
• .mp4 (MPEG-4)
• .avi (Audio Video Interleave)

Output Format

• .mkv (Matroska) - Provides excellent container for audio/subtitle preservation

Advanced Options

Supported Codecs

• Video: HEVC (H.265) - all encoders
• Audio: Copied as-is (no re-encoding, preserves quality)
• Subtitles: Copied as-is (preserves format and language info)

FFmpeg Command Structure

The script uses this FFmpeg command structure:

ffmpeg -i input.mkv -map 0:v:0 [audio] [subtitles] -c:v [encoder] -vf "scale=-2:[resolution]" [quality] -c:a copy -c:s copy output.mkv

Language Support

The script supports the following languages:

• 🇬🇧 English - Full support
• 🇪🇸 Spanish - Full support (Español)
• 🇮🇹 Italian - Full support with audio/subtitle detection

Adding More Languages

To add a new language:

1. Add a new condition in the :LANGUAGE_MENU section
2. Add corresponding message variables with your language's strings
3. Ensure language-specific functionality (like Italian audio detection) is adapted

Examples

Example 1: Quick Conversion to 720p

1. Run the script
2. Select: English → Generic (libx265) → 720p → Medium Quality
3. All videos in the folder convert to 720p medium quality

Example 2: GPU-Accelerated High-Quality Conversion

1. Run the script
2. Select: English → NVIDIA NVENC → 1080p → High Quality
3. Conversion is fast (GPU accelerated) with excellent quality

Example 3: 4K Archival

1. Run the script
2. Select: Spanish → Generic (libx265) → 2160p → Ultra Quality
3. High-quality 4K conversions suitable for long-term archival
