SnapOtterandGitHub 00b651c9f8 feat(i18n): 21-language pipeline, landing/docs/API wiring, landing+API translations

Shared Claude Code translation pipeline (scripts/i18n, no API key) plus Astro/VitePress/Scalar i18n wiring. Landing and API reference translated into all 20 languages; docs i18n wiring + English source anchors. The translated docs markdown (apps/docs/<locale>/**, 3,620 files) follows in a companion PR because it exceeds GitHub's per-PR CI file limit.

Reduce camera shake with two-pass stabilization.

Stabilize Video

Reduce camera shake in handheld footage using FFmpeg's two-pass vidstab stabilization.

API Endpoint

POST /api/v1/tools/video/stabilize-video

Accepts multipart form data with a video file and a JSON settings field. This is an async endpoint - it returns 202 Accepted immediately and progress is streamed via SSE at GET /api/v1/jobs/{jobId}/progress.

Parameters

Parameter	Type	Required	Default	Description
smoothing	integer	No	`15`	Smoothing window size in frames (5-60). Higher values produce smoother motion

Example Request

curl -X POST http://localhost:1349/api/v1/tools/video/stabilize-video \
  -H "Authorization: Bearer si_your-api-key" \
  -F "file=@clip.mp4" \
  -F 'settings={"smoothing": 30}'

Example Response

{
  "jobId": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
  "async": true
}

Notes

Stabilization is a two-pass process: the first pass analyzes camera motion, and the second pass applies the correction. This takes roughly twice as long as single-pass tools.
Higher smoothing values remove more shake but may introduce a slight zoom crop at the edges.
Progress updates are available via SSE at GET /api/v1/jobs/{jobId}/progress until the job completes.
