動画編集

Garden Watch Camのデータを編集する際はPiTiviという動画編集ソフトが便利。 他にもOpenshotという動画編集ソフトもある。

Pitiviのインストール

sudo apt-get install pitivi

Pitiviの使用方法

動画ファイルをインポートして、タイムラインに載せる。 タイムライン上で切り貼りして、使用したい時間帯だけ残す。 その後レンダリングする。

レンダリングの条件。

コンテナー形式はAvi 拡大比率は1280✕1040 フレームレートは10:1　(もしかしたら撮影間隔によって変更する必要があるかも) コーデックはJPEG image

動画から静止画像切り出し

 ffmpeg -ss 0 -vframes 100 -vf scale=1280:1040   -i  tmp.avi    -f image2 %06d.jpg

-ss 開始時間 -vframse 取り出したいフレームの枚数 -
