fontforgeによる等幅合成フォント作成時の注意点

make.pyはファイル名に使うべきではない

pythonをインストールしている環境ではmakeコマンドよりもmake.pyが優先して実行されることがあり混乱する。

cidFlattenは使うべきではない

同じコード値を示すグリフは複数ある場合がある。 この場合cidFlattenは期待しない結果となる。

Creating fast drawing video with ffmpeg

ffmpeg -i "concat:video1.ts|video2.ts|video3.ts" -c copy concat.ts
ffmpeg -i concat.ts -an -filter:v "setpts=0.03125*PTS" -c:v libx264 -preset ultrafast -crf 0 m32.mp4

• Use setpts=0.25*PTS for x4 video, setpts=0.03125*PTS for x32 video.
• Use -an to remove audio track.
