How to lower voice in iMovie?

Question

css

I did it somehow, but now I don't see it point-blank. You just need to make a voice below the video.

Answer 1

object-fit
Height will have to be set to 100% (if you can't write height, I don't know why, then you can stretch with an absolute or flex), because the height of your image is not enough to fill the entire area.
It is reasonable to use pictures with sizes proportional to the size of the block (in your case, square)
