+# Phase 6 Plan 1: GenerateVideo Node Summary
+
+**GenerateVideoNode component with fal.ai/Replicate provider selection and video generation API support**
+
+## Performance
+
+- **Duration:** 10 min
+- **Started:** 2026-01-09T10:16:14Z
+- **Completed:** 2026-01-09T10:25:55Z
+- **Tasks:** 2
+- **Files modified:** 7
+
+## Accomplishments
+
+- Created GenerateVideoNode component following GenerateImageNode pattern
+- Extended /api/generate route to handle video outputs from both Replicate and fal.ai
+- Added video playback display with HTML5 video element and controls
+- Integrated video node into workflow execution and regeneration
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Create GenerateVideoNode component** - `0c29ad1` (feat)
+2. **Task 2: Add video generation to API route** - `937480f` (feat)
+
+**Plan metadata:** Pending
+
+## Files Created/Modified
+
+- `src/components/nodes/GenerateVideoNode.tsx` - New video generation node with provider/model selectors
+- `src/types/index.ts` - Added generateVideo to NodeType, GenerateVideoNodeData interface, extended GenerateResponse
+- `src/store/workflowStore.ts` - Default data, execution logic, regeneration support
+- `src/components/WorkflowCanvas.tsx` - Node registration, handles, minimap color (#9333ea purple)
+- `src/components/nodes/index.ts` - Exported GenerateVideoNode
+- `src/app/api/generate/route.ts` - Video detection for Replicate/fal.ai, content-type handling
+- `src/lib/quickstart/validation.ts` - Added generateVideo to valid types
+
+## Decisions Made
+
+- Gemini excluded from video node (doesn't support video generation)
+- Large videos (>20MB) return URL directly to avoid memory issues with base64
+- Video detection: Replicate uses content-type headers, fal.ai uses result.video.url field
+- Video capabilities filter: text-to-video, image-to-video
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+
+None
+
+## Next Phase Readiness
+
+- GenerateVideoNode ready for testing with actual video models
+- Next plan (06-02) will add video playback to OutputNode for viewing generated videos
+- Video execution path untested with real providers (will be tested in 06-02)
