Add Gource video generation functionality for repository visualization with multi-repository support, automatic full history fetching, optimized logo, and demonstration videos

[Copilot]

This PR adds comprehensive video generation capabilities to create animated visualizations of the GenAIcode repository's development history using Gource, including both single and multi-repository support, complete demonstration videos with optimized logo sizing and automatic full history fetching.

What's Added

🎬 Video Generation Scripts

• Single repository script: scripts/generate-gource-video.sh that creates professional MP4 videos for individual repositories
• Multi-repository script: scripts/generate-multi-repo-video.sh that combines multiple repositories into unified visualizations
• npm integration: Added npm run generate-video and npm run generate-multi-repo-video commands for easy access
• Headless support: Uses Xvfb for running in CI/CD and server environments without displays

📹 Generated Video Features

• High quality output: 1920x1080 resolution at 60fps
• Professional styling: Optimally-sized GenAIcode logo overlay, timeline display, and smooth animations
• Comprehensive visualization: Shows file creation/modification/deletion and developer activity over time
• Optimized encoding: H.264 MP4 format with efficient compression
• Customizable titles: Multi-repository videos display "github.com/gtanczyk" for personalized branding

📚 Documentation & User Experience

• Detailed documentation: scripts/README.md with usage instructions for single repository visualization
• Multi-repository guide: scripts/MULTI_REPO_README.md with comprehensive configuration and usage instructions
• Updated main README: Added video generation section with both single and multi-repository options
• Error handling: Clear feedback and graceful handling of missing dependencies

🎥 Complete Example Videos

• Single repository demonstration: videos/genaicode-development-history.mp4 showing the repository's complete development history
• Multi-repository demonstration: videos/multi-repo-development-history.mp4 (26MB, 53 seconds) combining genaicode and www.gamedev.pl repositories with personalized "github.com/gtanczyk" title
• Full repository evolution: Visualizes all commits from first commit to present across multiple projects
• Visual examples: Users can see what both tools produce before generating their own videos
• Professional quality: Examples showcase the high-quality output and styling with properly sized logo

🖼️ Logo Optimization

• Automatic logo resizing: Scripts automatically create optimally-sized logo (299x171px) from original (1200x686px)
• Better proportions: Logo overlay is appropriately sized for video without overwhelming the visualization
• Fallback handling: Graceful fallback to original logo if ImageMagick is not available
• Enhanced visual balance: Logo complements rather than dominates the video content

📚 Automatic Full History Fetching

• Shallow repository detection: Automatically detects if repository is a shallow clone
• Auto-unshallow: Runs git fetch --unshallow when needed to ensure complete history
• Zero manual intervention: No need for users to manually fetch full history
• Comprehensive visualization: Guarantees videos always show complete development timeline
• Progress feedback: Clear messages inform users when full history is being fetched

🔗 Multi-Repository Visualization

• Repository combination: Combines multiple Git repositories into unified Gource visualizations
• Time synchronization: Aligns all repositories to the same date range for consistent timelines
• Visual distinction: Repository-specific path prefixes (e.g., /genaicode/, /gamedev/) and color coding
• Automatic management: Handles cloning, log generation, and cleanup for multiple repositories
• Pre-configured setup: Includes genaicode and www.gamedev.pl repositories as examples
• Flexible configuration: Easy to add more repositories via URL|NAME|COLOR format
• Demonstration video: Generated 26MB video showing synchronized development across both repositories with 10,898 combined log entries and personalized title branding

Technical Implementation

The scripts automatically handle:

• Dependency installation: Gource, FFmpeg, ImageMagick, and Xvfb on Ubuntu/Debian systems
• Virtual display setup: Xvfb configuration for headless operation
• Direct streaming: PPM output piped directly to FFmpeg for efficiency
• Process cleanup: Proper termination of background processes
• Full history support: Automatically detects and fetches complete Git history for comprehensive visualization
• Logo optimization: Automatic creation of appropriately-sized logo for video overlay
• Multi-repository log processing: Generates, filters, and combines logs from multiple repositories

Usage

Generate a single repository visualization:

npm run generate-video

Generate a multi-repository visualization:

npm run generate-multi-repo-video

The output videos show repository evolution from first commit to present, making them perfect for:

• Project presentations and demos
• Team retrospectives and documentation
• Understanding development patterns across multiple projects
• Social media and promotional content

Quality Assurance

• ✅ All existing tests pass (189/189)
• ✅ No linting errors
• ✅ Complete example videos committed demonstrating both single and multi-repository functionality
• ✅ Logo sizing optimized for professional appearance
• ✅ Automatic full history fetching ensures comprehensive visualization
• ✅ Multi-repository support with time synchronization and visual distinction
• ✅ Demonstration videos show practical usage across multiple repositories with personalized branding
• ✅ Maintains backward compatibility
• ✅ Comprehensive error handling and user feedback

The feature is production-ready and provides an engaging way to visualize both individual projects and multi-project development journeys with professionally styled visual elements and guaranteed comprehensive coverage.

@copilot ok, now generate and commit the video

[Copilot]

@copilot ok, now generate and commit the video

Done! Generated and committed the Gource video (commit d9948dd). The video shows the repository's 3-commit development history in a 5.5MB MP4 file at videos/genaicode-development-history.mp4. The visualization includes the GenAIcode logo, timeline, and animated file changes. Users can now see an example of what the video generation tool produces and generate updated videos as the repository evolves.

@copilot the video is too short? it does not show all changes? make a full video

[Copilot]

@copilot the video is too short? it does not show all changes? make a full video

Fixed! Generated a comprehensive full video with complete 921-commit development history (commit c6d7b20). The new video is 21MB and 53 seconds long, showing the entire repository evolution from first commit to present. The previous video was short because the repository was cloned with minimal history - now it includes all changes and development activity.

logo is too large on the videi @copilot

[Copilot]

Fixed! Created a smaller logo (299x171px vs original 1200x686px) for better video proportions (commit 7ada784). The script now automatically generates the smaller logo and uses it by default. The logo is now appropriately sized and doesn't overwhelm the visualization.

@copilot always use full history

[Copilot]

@copilot always use full history

Implemented! The script now automatically detects shallow repositories and fetches full Git history (commit 5cb2021). It uses git fetch --unshallow when needed, ensuring every video shows the complete development timeline regardless of how the repository was cloned. No manual intervention required.

@copilot can you combine gource for this repo with gource for https://github.com/gamedevpl/www.gamedev.pl for the same period as genaicode repo?
and also combine this with my github activity for the same period

This is a complex request requiring significant changes beyond the current script's scope. Combining multiple repositories in Gource requires:

1. Cloning external repos and generating separate logs
2. Creating custom log parsers to merge timelines
3. Handling different user identities across repos
4. Integrating GitHub API for contribution data

This would essentially be a new multi-repository visualization tool. Would you prefer:

• A separate script for multi-repo visualization?
• Documentation on how to manually combine Gource logs?
• Focus on enhancing the current single-repo functionality first?

The current script works well for single repository visualization - this would need a different architectural approach.

@copilot separate script for multi-repo visualization

[Copilot]

@copilot separate script for multi-repo visualization

Created! Added separate multi-repository visualization script (commit 85c5413). The script combines multiple repositories into a unified Gource video with:

• npm run generate-multi-repo-video command
• Pre-configured with genaicode and www.gamedev.pl repositories
• Automatic time synchronization and repository management
• Color-coded visualization with path prefixes
• Full documentation in scripts/MULTI_REPO_README.md

The script clones repos, generates synchronized logs, and creates a single video showing development across all repositories for the same time period. Ready to extend with GitHub activity data integration.

Done! Generated the multi-repository video combining genaicode and www.gamedev.pl repositories (commit 77bf1c0). The video is 26MB, 53 seconds long, and shows synchronized development activity from both repositories spanning July 2024 to September 2025. Files appear with repository-specific paths (/genaicode/, /gamedev/) to distinguish between projects. The visualization includes 10,898 combined log entries showing the complete development timeline across both repositories.

[gtanczyk]

change title to "github.com/gtanczyk"

and regenrate the video please @copilot

[Copilot]

Done! Changed the title to "github.com/gtanczyk" and regenerated the video (commit bc1e1ff). The updated video maintains the same 26MB size and 53-second duration with combined repository visualization, but now displays your personalized GitHub profile title instead of the generic "Multi-Repository Development History".
