Here on Easterhegg,
I was asked to record a 15min howto about hand soldering very small pitch chips.
I used 2 cameras and some vintage high aperture lenses as well as a professional audio recorder (using 24 bit 96KHz...more then will ever be required) and it turned out quite well.
I cut everything here on Easterhegg (lip-sync, intro, end, switching between cameras, cleaning up, ...) and gave it to the people who asked be for it.
They will finalize my cut and I asked to be allowed to present the final video
on my YouTube channel, when it is done.
