+# Phase 6 Plan 2: Video Playback Summary
+
+**OutputNode now displays video with playback controls, downloads as .mp4, and receives video from GenerateVideo pipeline**
+
+## Performance
+
+- **Duration:** 28 min
+- **Started:** 2026-01-09T10:40:34Z
+- **Completed:** 2026-01-09T11:09:05Z
+- **Tasks:** 3
+- **Files modified:** 4
+
+## Accomplishments
+- OutputNode detects video content and renders HTML5 video element
+- Video playback with controls, loop, muted autoplay, playsinline
+- Video download with .mp4 extension (handles both data URLs and HTTP URLs)
+- Lightbox shows full-size video player
+- GenerateVideo output connects to downstream nodes in workflow
+- Output node sets contentType field for explicit video/image distinction
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Update OutputNode for video detection and playback** - `b935bc7` (feat)
+2. **Task 2: Connect generateVideo output to workflow pipeline** - `5d8c175` (feat)
+3. **Bug fix: Create generateVideo node for video models in browser** - `28c3edb` (fix)
+
+**Plan metadata:** (this commit)
+
+## Files Created/Modified
+- `src/types/index.ts` - Added video and contentType fields to OutputNodeData
+- `src/components/nodes/OutputNode.tsx` - Video detection, playback, and download
+- `src/store/workflowStore.ts` - generateVideo in getConnectedInputs, video content type in output execution
+- `src/components/modals/ModelSearchDialog.tsx` - Create correct node type for video models
+
+## Decisions Made
+- Video detection uses data URL prefix (data:video/) or file extension (.mp4, .webm)
+- Both data URLs and HTTP URLs handled natively by video element
+- Video element attributes: controls, loop, muted, autoPlay, playsInline
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Bug] ModelSearchDialog creating wrong node type for video models**
+- **Found during:** Task 3 (Human verification checkpoint)
+- **Issue:** Model browser always created nanoBanana nodes regardless of model capabilities, so video models weren't pre-selected
+- **Fix:** Check model capabilities for text-to-video/image-to-video and create generateVideo node instead
+- **Files modified:** src/components/modals/ModelSearchDialog.tsx
+- **Verification:** Selecting video model from browser now creates GenerateVideoNode with model selected
+- **Committed in:** 28c3edb
+
+---
+
+**Total deviations:** 1 auto-fixed (bug)
+**Impact on plan:** Bug fix necessary for correct video model selection workflow. No scope creep.
+
+## Issues Encountered
+None
+
+## Next Phase Readiness
+- Video generation pipeline complete: Prompt → GenerateVideo → Output
+- Ready for 06-03: Custom model parameters from provider schemas
+- All video playback and download functionality working
