GIT Converter v2.7 - Setup Instructions

Overview

GIT Converter v2.7 is a modular video conversion tool with automatic hardware detection and optimization. It supports AV1 and HEVC encoding with various quality settings, color correction options, and smart upscaling.

Setup Instructions

1. File Structure Setup

• Ensure all files remain in the same directory structure
• The modules/ folder must be alongside the main script
• Do not rename or move individual module files

2. Make Script Executable

Windows:

1. Right-click on git_converter.sh
2. Properties → Permissions → "Allow executing file"
3. Click OK

Or in Git Bash:

chmod +x git_converter.sh

3. Dependencies

• FFmpeg with encoder support (libx265, libsvtav1, hevc_amf, etc.)
• Git Bash (for Windows users)
• GPU Drivers (NVIDIA, AMD, or Intel) for hardware acceleration

Usage Methods

Method 1: Double-Click (Batch Processing)

1. Double-click git_converter.sh
2. Hardware detection runs automatically:

   Detecting hardware and optimal encoder...
    ✓ AMD GPU detected
    Testing hevc_amf...
       hevc_amf: 0.8s
    ✓ Selected: hevc_amf (fastest encoder)
   

3. Follow menu prompts for resolution, FPS, quality, and color correction
4. Processes all videos in the same directory

Method 2: Drag & Drop (Selective Processing)

1. Select video files in Windows Explorer
2. Drag them onto git_converter.sh
3. Same menu flow as double-click method
4. Processes only dragged files

Menu Options

Resolution Settings

• Source: No upscaling (original resolution)
• 720p/1080p/1440p/4K: Fixed resolution upscaling
• 2X/4X: Relative upscaling (double/quadruple size)

Scaling Algorithm (when upscaling)

• Bicubic: Fast, good quality
• Lanczos: Best quality, slower
• Bilinear: Fastest, basic quality

FPS Settings

• Original FPS: Maintains source frame rate
• 60 FPS: Converts to smooth 60fps motion

Quality Modes

• High Quality (CRF 18): Recommended balance
• Near-Lossless (CRF 16): Maximum quality
• Good Quality (CRF 20): Balanced size/quality
• Custom bitrate: Manual bitrate control

Color Correction Options

1. No correction: Original colors
2. Pink skin tones: Fixes Topaz AI color loss
3. Warm boost: Increases warmth
4. Cool boost: Increases cool tones
5. 2000s DVD Restore: Fixes DVD degradation
6. 90s Quality Restore: Restores 90s media
7. VHS Quality Restore: Repairs VHS degradation
8. Anime Preservation: Protects anime art style

Hardware Detection

The script automatically detects and tests:

• NVIDIA GPUs: Uses NVENC encoders
• AMD GPUs: Uses AMF encoders
• Intel GPUs: Uses Quick Sync Video
• No GPU: Uses optimized CPU encoders

Encoder Priority

1. Hardware encoders (GPU acceleration)
2. SVT-AV1 (fast CPU encoding)
3. libx265 (fallback CPU encoding)

Output Structure

Converted Folder

• Automatically created in script directory
• Contains all converted files
• Original files remain untouched

File Naming Convention

[original_name]_[fps]_[color]__cv.[extension]

Examples:
- vacation.mp4 → vacation__cv.mkv
- wedding.mp4 → wedding_60fps__cv.mkv
- old_tape.avi → old_tape_vhsrestore__cv.mkv
- anime.mkv → anime_anime__cv.mkv

Performance Features

Optimizations

• Hardware detection: Uses fastest available encoder
• Modular loading: Faster startup, less memory
• CRF encoding: Consistent quality vs variable bitrate
• Smart filter chains: Proper ffmpeg parameter ordering

Quality Settings

• AV1: Best compression, smaller files
• HEVC: Faster encoding, good compression
• CRF 16-22: Near-lossless to balanced quality
• GPU acceleration: 10x+ faster than CPU encoding

Troubleshooting

Common Issues

"No video files found"

• Cause: Script folder contains no supported videos
• Solution: Move script to folder with videos or drag files onto it

"No working encoder found"

• Cause: FFmpeg missing encoder support
• Solution: Install GPU drivers or rebuild FFmpeg with encoder support

"Failed to process"

• Cause: Permission issues, disk space, or corrupted file
• Solution: Check file permissions and available disk space

Slow encoding (0.1 FPS)

• Cause: Using slow CPU encoder (libaom-av1)
• Solution: Script auto-selects fastest encoder, ensure GPU drivers are installed

Supported Formats

• Input: MP4, MKV, MOV, AVI, WMV, TS, M2TS
• Output: MKV (recommended) or MP4
• Codecs: AV1, HEVC (H.265)

Performance Tips

• For quality: Use Lanczos scaling + CRF 16-18
• For speed: Use Bicubic scaling + CRF 20
• For storage: Use HEVC + CRF 20-22
• For old content: Use appropriate color correction option

Advanced Usage

Keyboard Shortcuts

• Enter: Confirm selections
• Numbers: Quick menu selection
• Ctrl+C: Cancel script

Custom Workflows

• Topaz AI videos: Use "Pink skin tones" correction
• DVD content: Use "2000s DVD Restore"
• Anime: Use "Anime Preservation" mode
• Family videos: Use "Warm color boost"

Batch Processing

• Place multiple videos in same folder
• Double-click script for batch conversion
• All files processed with same settings
