The procedure above is straight forward and worked before with an earlier version of iMovie. The specific camcorder I am using appears in the left column of the import window. When I select it, I get a blank view box with rewind, play and fast forward arrows (no image). Close and import buttons are to the bottom-right. Import is highlighted blue. The rewind, play and fast forward buttons are highlighted but do nothing. Import is highlighted blue but also does nothing when selected. My camcorder is in VCR mode per the user manual. I have tried various power-up and re-attachment combinations. I wish I could remember which version of iMovie I had when this worked (it was 2018). I think I've already updated all my other apple devices in the house.
