Presentation Video Step 3 Implementation Log

Created: 2026-05-26 02:46 UTC

Status

Implementation completed on 2026-05-26. Step 3 now supports editable pause timing, popup draft voiceover regeneration with explicit commit/discard behavior, refreshed preview and deferred audio timing propagation, and the updated layout direction without Why This Visual.

Completed Tasks

  • [x] Added shared helpers so Step 3 timing prefers actual ElevenLabs word timings before falling back to stored or estimated durations.
  • [x] Exposed editable float pauseSeconds in the scene editor and persisted it through updatePresentationScene.
  • [x] Added draft voiceover audio actions for generate, discard, and commit without mutating the scene until Done.
  • [x] Reworked the voiceover popup so regenerated draft audio can be previewed, replaced, canceled, or committed explicitly.
  • [x] Updated preview stale handling so pause edits and committed popup edits require preview recompilation before final video generation.
  • [x] Reworked Step 3 layout toward the provided mockup, including sticky mobile preview behavior and removal of Why This Visual.
  • [x] Refreshed Generate VO Audio so dirty or missing scenes regenerate actual timing metadata and update the latest compilation snapshot in place.
  • [x] Added targeted integration and e2e coverage around the new Step 3 behavior.
  • [x] Updated core and state docs to match the implementation.

Code Changes

  • src/app/(frontend)/app/presentation/actions.ts Added timing helpers, draft audio lifecycle actions, pauseSeconds persistence, committed asset cleanup, and in-place compiled snapshot refresh after deferred audio generation.
  • src/components/anuvax/presentation-video/presentation-video-page.tsx Added popup draft audio state, pause inputs, layout changes, sticky mobile preview behavior, removal of Why This Visual, and preview precedence so uploaded or selected visuals render even for scenes whose recommended content type is text.
  • scripts/presentation-worker.ts Updated worker-side voiceover persistence to store actual durations and word timing metadata consistently.
  • tests/integration/helpers/presentation-harness.ts Exposed new Step 3 actions to the integration harness.
  • tests/integration/presentation-assistants.integration.test.ts Added draft generate/discard and draft commit coverage.
  • tests/integration/presentation-scene-edit-preview.integration.test.ts Added pause timing and deferred audio refresh coverage against compiled config behavior.
  • tests/e2e/presentation-video.e2e.spec.ts Added popup draft audio regeneration coverage for the Step 3 route and a regression test for visual preview precedence on text scenes.

Verification

  • pnpm exec biome check src/app/(frontend)/app/presentation/actions.ts src/components/anuvax/presentation-video/presentation-video-page.tsx scripts/presentation-worker.ts tests/integration/helpers/presentation-harness.ts tests/integration/presentation-assistants.integration.test.ts tests/integration/presentation-scene-edit-preview.integration.test.ts tests/e2e/presentation-video.e2e.spec.ts Passed.
  • pnpm exec tsc --noEmit Passed.
  • pnpm exec vitest run --config ./vitest.config.mts tests/integration/presentation-assistants.integration.test.ts tests/integration/presentation-scene-edit-preview.integration.test.ts tests/integration/presentation-compile.integration.test.ts Passed.
  • pnpm exec playwright test tests/e2e/presentation-video.e2e.spec.ts Blocked by environment configuration in playwright.config.ts: Node could not resolve the dotenv package before the test suite started.

Decisions

  • Draft popup audio is stored temporarily using existing voiceover_audio_assets records rather than adding a new schema.
  • The latest compilation snapshot is refreshed in place after deferred bulk audio generation; Generate Slides Preview remains the only action that creates a new preview compilation row.
  • Scene duration authority now prefers actual TTS word timings to keep computedStartSec, computedEndSec, and compiled voiceover metadata aligned.
  • Replaced committed voiceover assets are deleted after successful replacement to reduce orphaned audio records.

Remaining Risks

  • Playwright verification is still blocked by the missing dotenv dependency in the current local test environment, so the new Step 3 e2e scenario is added but not fully executed here.
  • Deferred bulk audio generation now refreshes compiled metadata inline in the action path used by the UI. If any external job path bypasses that action, it should be checked separately for parity.
