## Definitions

### `social.skyphone.video.post`

**Type**: `record`

Canonical video record. The video blob and durationMs MUST NOT change after creation; replacing the video requires a new record. This record intentionally carries no human-readable metadata: title, description, thumbnail and the announcement post live in a social.skyphone.video.meta record with the same record key in the same repo.

**Key**: `tid`

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `video` | `blob` | Yes | Server-side transcoded canonical video (H.264/AAC, up to 1080p, at most 1GB). |
| `compat` | `blob` | No | Bluesky-compatible mp4, only produced for videos of 3 minutes or less, at most 100MB. |
| `captions` | `array` | No | Optional WebVTT caption tracks, same shape as app.bsky.embed.video#caption. Absence means no captions were supplied; it does not mean the video has burned-in subtitles. |
| `createdAt` | `string` (datetime) | Yes | When this record was created. |
| `durationMs` | `integer` | Yes | Duration in milliseconds, as measured by the transcoding worker (ffprobe), not client-reported. |
| `aspectRatio` | `ref` → `app.bsky.embed.defs#aspectRatio` | Yes | Pixel dimensions of the canonical video, as measured by the transcoding worker. Required so clients can reserve layout before the blob is fetched. |
