[AppleScript]ffmpeg用のコマンドを整形する（ムービーから選択範囲を切り出す）
QuickTime（もう終わった技術なのね…）プレーヤーで
選択範囲を切り出します。
ffmpeg用のコマンドを整形だけのスクリプト
コマンドはターミナルで実行します。
QuickTimeで切り出したい選択範囲を作ったら
スクリプトを実行します
↑
ここにコマンドがログとして出力されます
これをコピーして
ターミナルにペーストします
終了すると
選択部分のみ書出されます。
(*
QuickTimeプレーヤー上での選択範囲を
ffmpegで切り出すコマンドに整形します。
ffmpegが必須
QuickTime Player 7用なのでOS的には10.9までか？
