The problem REELIO solves
Problem 1: User research costs $10K+, takes 2-3 weeks, misses emotional context
Problem 2: Content creation takes 10+ hours, costs $500-1K, subjective moment selection
Problem 3: Fragmented tools—no unified solution for interviews + content
Challenges we ran into
1)Real-Time Emotion Fusion: Syncing 3 data streams (video 30 FPS, audio 16kHz, text) with <100ms latency
2)SadTalker GPU Bottleneck: 5-10s blocking operation limits to 1-2 concurrent users.Also the resources to run it.
3)WebSocket State Management: Memory leaks, disconnections, session cleanup
4)BM-DETR Alignment: Syncing visual (per frame), audio (per second), semantic (per sentence) scores
5)API Rate Limits & Costs: Balancing OpenAI, ElevenLabs, ZapCap within budget
