All 181 docs markdown files translated into 20 languages (apps/docs/<locale>/**). Companion to the i18n code PR; admin-merged because the file count exceeds GitHub's per-PR CI trigger limit. Validated by pnpm i18n:check (all surfaces, 0 stale/missing) and a clean all-locale docs build.

|
|
"downloadUrl": "/api/v1/download/a1b2c3d4-e5f6-7890-abcd-ef1234567890/clip.mp4",

|
|
## Notes {#notes}
|
|
|
|
- 裁切區域必須位於影片尺寸範圍內。若 `x + width` 或 `y + height` 超出來源大小,請求會回傳 400 錯誤。
|
|
- 最小裁切尺寸為 16x16 像素。
|
|
- 尺寸會四捨五入為偶數,因為大多數影片編解碼器都有此要求。
