Why you are very wise to use a video imager... This actually came from
personal experience where I used a "solar rated" neutral density filter
with my telescope can came very close to burning out an eye when it
fractured...

At the least it's better to burn the camera than the eyeball.

Do beware, Optical paths through cameras/telescopes can get VERY HOT
observing the sun. Optical coatings were not designed to be pointed
directly at the sun for long periods of time and can overheat and
destroy your optics. Pin holes may solve the problem or just make a
large heat differential. This is the time for a heavy duty neutral
density filter in front of all your optics...

If you are fortunate enough to be able to see the eclipse on the 21st,
low cost optical filters can be made out of a double layer of
aluminized Mylar space blankets.
$1.99, cut up many strips and you have your viewing glasses and
dozens to give away.
And of course you don’t need any eye protection during totality.
