C:\yt-dlp\yt-dlp_win>yt-dlp.exe --cookies "cookies.txt" "https://www.youtube.com/watch?v=-(略)" ERROR: Cookies file must be Netscape formatted, not JSON. See https://github.com/yt-dlp/yt-dlp/wiki/FAQ#how-do-i-pass-cookies-to-yt-dlp ERROR: Cookies file must be Netscape formatted, not JSON.

yt-dlp 不接受 JSON 格式的 cookies，必須是 Netscape 格式（傳統 cookies.txt 格式）。你現在的 cookies.txt 是 JSON 格式（EditThisCookie V3 預設匯出就是 JSON）。

解決方法：用 EditThisCookie 匯出 Netscape 格式

在 Chrome 工具列點 EditThisCookie 小餅乾圖示 → 打開面板。

點面板右上角 Export 下拉箭頭。

選擇 “Export as Netscape Format”。

這樣匯出的文字就是 yt-dlp 可以用的 cookies.txt。
