 # M4 Response: FFmpeg DrawText 選型回饋
 
+## M4 已處理
+
+| 問題 | 狀態 |
+|------|------|
+| ffmpeg 無 `drawtext` | ✅ M4 已安裝 `ffmpeg-full`（`brew install ffmpeg-full`），link 覆蓋原 ffmpeg |
+| `drawtext` filter 可用 | ✅ 已確認 |
+| trace #2 (1 det) video | ✅ 200 OK (1MB) |
+| trace #5 (2 dets) video | ✅ 200 OK (1.9MB) |
+| trace #3128 (1109 dets) | ❌ 仍 500（ARG_MAX overflow，需等 M5 修 code） |
+
 ## 核心遺漏：ARG_MAX overflow
 
 M5 的選型評估沒有解決 **真正導致 500 的原因** — `trace_video()` 為 trace #3128 (1109 detections) 產生的 filter_complex 字串超過 macOS 命令列長度限制 (~256KB)。
