# 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.
|
||
|
||
**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** — confirm the vertical local recording uses the same crop and
|
||
composed picture as the live stream, not merely the same dimensions.
|
||
|
||
**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).
