# TASK 53 — Output-format verification: vertical and landscape outputs (queued 2026-10-08)

> Catalog: [`TASKS.md`](../TASKS.md) — status and requirements live here.

**Why:** the site claims vertical 1080p60 (9:16), but the full route from compositor crop through
FFmpeg scaling to YouTube and the local recording needs verification.

**Goal:** prove each output tier has the expected dimensions and frame rate, and that vertical live
and recorded outputs preserve the composed image. Creators control layer placement; this task does
not promise platform-specific safe zones or keep content clear of every viewer overlay.

### Status: ✅ Complete — creator accepted 2026-11-04

**Slices (one integration test each, in order):**

1. ✅ **What we actually emit** (2026-11-04; creator visually reviewed and accepted) — six
   creator-supplied recordings confirm the emitted configurations. All are H.264 with exact
   average frame rates and dimensions:

   | Mode | File | Output |
   |---|---|---|
   | Landscape 1080p60 | `rec1-1080p60.mp4` | 1920×1080 @60 fps |
   | Landscape 1080p30 | `rec2-1080p30.mp4` | 1920×1080 @30 fps |
   | Landscape 720p60 | `rec3-720p60.mp4` | 1280×720 @60 fps |
   | Landscape 720p30 | `rec4-720p30.mp4` | 1280×720 @30 fps |
   | Vertical 1080p30 | `rec5-1080p30-vert.mp4` | 1080×1920 @30 fps |
   | Vertical 1080p60 | `rec6-1080p60-vert.mp4` | 1080×1920 @60 fps |
2. ✅ **9:16 output resolution (resolution-only acceptance, 2026-11-04)** — creator-supplied
   `ty-20261104-0927-982-0000-2.mp4` reports H.264 1080×1920 at 60 fps. The creator accepted the
   resolution only; no platform-specific safe-zone promise is part of acceptance.
3. ✅ **Vertical YouTube live-player check** (creator confirmed 2026-11-04) — the 9:16 stream
   displays vertically without distortion or letterboxing. Layer placement relative to YouTube
   controls remains creator-controlled; platform-specific safe zones are not a requirement.
4. ✅ **Recorded .mp4 matches output** (creator accepted 2026-11-04) — the creator visually reviewed
   and accepted the six output recordings and the vertical YouTube live-player result.

**Design decisions:**

- Geometry is a contract with tests, not a hope. Derived ratios (stream vs composite vs canvas)
  get a derived-value test so one change can't silently wreck Shorts/TikTok output.
- Keep widescreen untouched — only add what vertical needs (the existing test suite stays green
  for 16:9).
