The AI Video Stack That Costs $0 Per Clip
Published: 2026-03-06 · 8 min read · Series: Building in the Open
There are two practical lanes right now: a free local lane for experimentation and a cloud lane for client-ready output.
Lane 1: Local generation (LTX-Video)
LTX is real and installable on Apple Silicon, but current local benchmark behavior on this hardware profile was not yet a reliable fast-iteration workflow for production clips.
Use local generation when cost is priority and timing is flexible.
Lane 2: Cloud stack (Claude → Sora 2 → Topaz)
Step 1: Prompt engineering in Claude
Use structured prompt language for scene, camera movement, lighting, subject details, and style constraints.
Step 2: Generate in Sora 2
Run multiple variations per prompt and keep only top candidates.
Step 3: Finish in Topaz
Upscale, stabilize, and interpolate for final delivery quality.
Cost math
- Local lane: $0/month, $0 per clip
- Cloud lane: ~$225/month flat, effectively $0 marginal per clip
- Hybrid: production cloud + local experimentation
Recommended workflow
Ship with the cloud lane today. Keep local lane installed and warm for periodic re-benchmarking as model/runtime support improves.
