29. echo -e "\nusage: shot [options] [file] ... [fileN]\n
    
30. Options:
    
31.   -t <time> - Set time (in minutes) between screenshots; the number of screenshots is calculated automatically.
    
32.   -n <number> - Set a fixed number of screenshots to take.
    
33.   -m - Manual mode. Use arrows to FF/rewind. Press [S] to make screenshots. Quit mplayer to continue.
    
34.   -r <percent> - Change the size of the output image. Less than 40% is recommended.
    
35.   -s - Seed mode. Gives extra video and audio information. Removes spaces from filenames.
    
36.   -h - Display this help message\n
    
37. 
    
38. If you don't like screenshots run the script again.
    
39. This script depends on Mplayer and ImageMagic. Make sure you have them installed.\n

You got it.

话说，有没有能将某段视频截取为gif的脚本？

可以分拆为许多单个图片，然后用 convert 转换一下，不过不要期待效果太好，文件体积也可能比较可怕……

今天发布视频种子。刚好用上这脚本。

折腾了大半天，总算把字幕给截图进去了。
