video file cannot be reverted
I have been making video and importing them to imovie all week with no problem, by emailing the video to myself and transferring it to imovie. No problems.
After editing a video yesterday that I transferred to imovie by plugging my phone in, I suddenly find if I unplug my phone all the videos in the imovie panel go black and it says no camera connected.
I subsequently tried emailing them again, opening them in Quicktime player so I could MOVE TO... another file. This has been working perfectly all week, but now it tells me the video cannot be reverted.
I am on a timeline to deliver this video and I cannot work with imovie
Please help!
I am using
MacOS Big Sur 11.2.1 on a macbook pro, and my videos are on iphone 7
