case1:假如解析度，幀率，編碼都相同，則用一個 list.txt 搭配 ffmpeg 即可瞬間合併。

  list.txt裡頭為多行結構，每行都是 file '.......mp4'

  ffmpeg -f concat -safe 0 -i list.txt -c copy output.mp4

case2:假如要縮放解析度到 1560x1080，調整幀率為 30.303，則用

  ffmpeg -i input.mp4 -vf scale=1560:1080 -r 30303/1000 -c:v libx264 -crf 18 -preset slow -c:a copy output.mp4

cjk unicode的收錄好像完整度高，也開源，再確認一下

下面這個軟體，可以新增字型
