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

Phase: 06-video-and-polish Completed: 2026-01-09
