I emailed them. I don't know. they may be doing what we are doing.
What if we tried a proof of concept.
- let's pick a recording, like maybe yugen himen from yiddish NY
- you sing it and record yourself while listening to it in a headphone
- send me the recording of you then I sing it and record it while listening to you
- then I/we fuck around with audacity and see if I can sych them up
- then I/we synch up the videos based on timestamps from audacity
if that works we try stage 2:
- we get Peri or Jenny or Linda to do the same thing for other voices
- then I/we fuck around with audacity and see if I can synch them up
- then I/we synch up the videos based on timestamps from audacity
If we could develop some kind of process for learning new music, I think I would stay involved. Maybe:
- Derek introduces a new song and we learn pronunciation, rhythm, melody and our parts while muted.
- Section leaders follow up with recordings we can have in our headphones while we sing, eventually recording ourselves.
- We listen to each other and talk about it.
- Mini's or section leaders do the same process and create recordings of all 4 voices
- We start to sing with the other voices, eventually recording ourselves again

my_clip = VideoFileClip("some_file.mp4")
my_clip.set_start(t=5) # does nothing, changes are lost
my_new_clip = my_clip.set_start(t=5) # good !
Time representations in MoviePy
Many methods that we will see accept times as arguments. For instance clip.subclip(t_start,t_end) which cuts the clip between two times. For these methods, times can be represented either in seconds (t_start=230.54), as a couple (minutes, seconds) (t_start=(3,50.54)), as a triplet (hour, min, sec) (t_start=(0,3,50.54)) or as a string (t_start='00:03:50.54')).
