Generates full debate-format videos between multiple public figures by orchestrating a pipeline that accepts user-provided debate prompts, routes them through an LLM to generate dialogue scripts with speaker attribution, converts each speaker's lines to speech using pre-trained RVC (Retrieval-based Voice Conversion) models fine-tuned on celebrity voice samples, synchronizes audio tracks, and renders final video output using Remotion with character animations. The system maintains separate voice models per public figure (stored in training_audio/ directory) and uses tRPC API endpoints to manage the generation workflow across distributed backend services.
Unique: Uses pre-trained RVC (Retrieval-based Voice Conversion) models with celebrity voice samples rather than generic TTS, enabling character-specific voice synthesis that maintains speaker identity across generated dialogue. Integrates Remotion for client-side video rendering with tRPC backend orchestration, allowing distributed processing across AWS EC2 instances without relying on third-party video APIs.
vs alternatives: Achieves lower latency and cost than cloud-based video APIs (Synthesia, D-ID) by running RVC locally and using Remotion's browser-based rendering, while maintaining character voice fidelity through fine-tuned models rather than generic voice cloning.
Accepts a user-provided topic or debate prompt and routes it through an LLM (ChatGPT via API) to generate multi-turn dialogue scripts with explicit speaker labels and turn-taking structure. The system parses LLM output to extract speaker names, dialogue lines, and optional stage directions, then validates speaker names against the pre-trained voice model registry before passing to the TTS pipeline. This ensures generated scripts only reference available voice models and maintains consistent speaker identity throughout the video.
Unique: Implements speaker registry validation that constrains LLM output to only reference pre-trained voice models, preventing generation of dialogue for unavailable speakers. Uses structured parsing to extract speaker attribution and dialogue lines, enabling downstream voice synthesis without manual script editing.
vs alternatives: More flexible than template-based dialogue generation because it leverages LLM reasoning to create contextually appropriate debate arguments, while maintaining safety through speaker registry constraints that prevent out-of-scope voice model requests.
Implements a specialized video mode (monologue) that generates single-speaker narration from a topic prompt, with the LLM generating a coherent speech from one character's perspective. The system renders monologue videos with full-screen character focus and optional background visuals, enabling character-driven storytelling without multi-speaker dialogue. Monologue mode is optimized for faster rendering (shorter videos, single audio track) and lower LLM costs (single speaker generation).
Unique: Optimizes the entire pipeline (LLM, TTS, rendering) for single-speaker content, reducing complexity and rendering time compared to multi-speaker modes. Generates character-appropriate monologues via LLM prompts tuned for individual speaker voice and perspective.
vs alternatives: Faster and cheaper to render than debate or podcast modes because it requires single audio track and simpler Remotion composition. Better suited for character-focused storytelling than generic video generation platforms.
Implements asynchronous video rendering via a job queue stored in the pendingVideos database table, with CI/CD pipeline (.github/workflows/deploy-ec2.yml) that deploys rendering workers to AWS EC2 instances. When a user requests video generation, the system enqueues a job in pendingVideos, and distributed EC2 workers poll the queue, claim jobs, execute the Remotion rendering pipeline, upload completed videos to S3, and update the videos table. This architecture decouples user requests from rendering latency, enabling horizontal scaling without blocking the API.
Unique: Uses database-backed job queue (pendingVideos table) instead of message queue services (SQS, Kafka), enabling simple deployment without additional infrastructure. Implements CI/CD pipeline (.github/workflows/deploy-ec2.yml) that automates EC2 worker deployment, enabling rapid scaling and updates without manual SSH access.
vs alternatives: Simpler to deploy than SQS-based queues because it uses existing database infrastructure, though less scalable at very high throughput (>1000 jobs/minute). More cost-effective than serverless rendering (Lambda) because EC2 instances can be kept warm and reused across multiple jobs.
Packages RVC voice conversion service in a Docker container (rvc/Dockerfile) with Python dependencies (rvc/requirements.txt), enabling isolated, reproducible deployment of the voice conversion backend. The container runs RVC inference with GPU support (NVIDIA CUDA), accepts audio input via HTTP API, performs voice conversion, and returns converted audio. Docker containerization decouples RVC from the main Node.js backend, allowing independent scaling and updates.
Unique: Isolates RVC voice conversion in a Docker container with GPU support, enabling independent scaling and updates without affecting the main Node.js application. Dockerfile includes all Python dependencies and CUDA configuration, ensuring reproducible deployments across environments.
vs alternatives: More isolated than running RVC directly in Node.js because Docker provides process isolation and dependency management. Enables GPU acceleration without requiring GPU support in the main application runtime.
Stores generated MP4 video files in AWS S3 buckets with signed URLs for secure, time-limited access. The system uploads completed videos from EC2 rendering workers to S3, stores S3 URLs in the videos database table, and generates signed URLs (valid for 1 hour) for user downloads. S3 can be configured with CloudFront CDN for geographic distribution and faster delivery to users worldwide.
Unique: Uses S3 signed URLs with 1-hour expiration for secure, time-limited access without requiring authentication on each request. Integrates with CloudFront CDN for geographic distribution, enabling fast video delivery to users worldwide without additional infrastructure.
vs alternatives: More scalable than local disk storage because S3 handles large files efficiently and provides built-in redundancy. Cheaper than proprietary CDN services because CloudFront pricing is transparent and scales with usage.
Converts generic text-to-speech audio (generated via Speechify API) into celebrity-specific voices by running inference on pre-trained RVC (Retrieval-based Voice Conversion) models. Each public figure has a dedicated RVC model trained on their voice samples (stored in training_audio/ directory), and the system loads the appropriate model based on speaker selection, applies voice conversion to the TTS audio, and outputs character-specific speech. The RVC backend runs in a Docker container (rvc/Dockerfile) with Python dependencies (rvc/requirements.txt) and is orchestrated via tRPC API calls from the main backend.
Unique: Uses RVC (Retrieval-based Voice Conversion) instead of traditional voice cloning, which preserves speaker identity and prosody from training samples while converting generic TTS audio. Maintains separate pre-trained models per celebrity, enabling instant voice switching without retraining. Containerizes RVC inference in Docker, allowing distributed deployment across GPU-enabled EC2 instances.
vs alternatives: Achieves higher voice fidelity than generic voice cloning APIs (ElevenLabs, Google Cloud TTS) because RVC leverages pre-trained models fine-tuned on real celebrity speech, while remaining cheaper than custom voice cloning services that require extensive training data collection.
Orchestrates video rendering using Remotion (React-based video framework) to compose character animations, background visuals, and synchronized audio tracks into a final MP4 file. The system defines React components for each video mode (debate, podcast, monologue, rap) that accept dialogue scripts and audio files as props, renders frames at specified FPS, and outputs video with audio sync. Rendering is triggered via tRPC API endpoint (src/app/api/create/route.ts) and can be distributed across multiple EC2 instances via a job queue (pendingVideos table) to handle concurrent requests.
Unique: Uses Remotion (React-based video framework) instead of traditional FFmpeg or video encoding libraries, enabling declarative video composition as React components. Integrates with tRPC backend to queue rendering jobs across distributed EC2 instances, allowing horizontal scaling without blocking user requests. Supports multiple video modes (debate, podcast, monologue, rap) with different visual layouts defined as separate React components.
vs alternatives: More flexible than FFmpeg-based pipelines because video composition is defined as React code rather than command-line parameters, enabling dynamic layout changes and custom animations. Cheaper than cloud video APIs (Synthesia, D-ID) because rendering runs on self-hosted EC2 instances, though requires more operational overhead.
