 I have to say in some ways, it was great that the video live stream failed, otherwise I would not have been able to download the video stream - the best thing I could have done was doing a screen capture. I did not figure out how to download live stream until Wednesday morning. My housemates had their ceremony on Tuesday morning - all I could do for them was doing a screen capture.  I have to say in some ways, it was great that the video live stream failed, otherwise I would not have been able to download the video stream - the best thing I could have done was doing a screen capture.

 Another one of my friend had her certain ceremony on Friday. After obtaining videos for two separate ceremonies, I wonder if I could take my art further. I felt the screen captures I did for my housemates was not good enough.  Another one of my friend had her certain ceremony on Friday.

 The first command generates the list of the video fragments to be concatenated. Note the ''-V'' option in ''sort'', by using that option, the filenames are sorted in "natural sort". So if you have numbers "1 3 10 2", it gets sorted into "1 2 3 10" rather than "1 10 2 3". Normally ''sort'' sorts texts character-by-character.  The first command generates the list of the video fragments to be concatenated.
