lilypond score in youtube video

[Martin Tarenskeen]

Hi,

I want to make some YouTube video's combining audio and Lilypond created 
pages.
I don't mind to do some simple video editing manually, so not everything 
needs to be totally automized.

The idea is to output some png images from my lilypond score to use in my 
video editing software and synchronize the pageturns with a corresponding 
audio track. The audio may be created either from a MIDI track generated 
by LilyPond, or from a real human recording.

I am probably not the first person who tried this. So maybe you can 
share your experience?

Q1: What pagesize and staffsize do you recommend to use in my lilypond 
score? Does anyone have an example or template that works well?

Q2: On the commandline if I use the --png option, what 
resolution xxx do you recommend for the  option -deresolution=xxx?

Q3: What good-enough-for-this-purpose audio and video fileformats and 
audio and video resolution/size should I use for such YouTube video's?

P.S. I want to use such video's as part of my online musiclessons for my 
pupils. COVID-19 forces me to learn many new skills. Take care everyone. 
Hope everyone is well.
