How to convert apple mov to ordinary jpg
My camera started taking "live" .mov pics without my consent or Knowledge. I know now how to switch the "lovely" unwanted new feature off and have done that but I now have 100s of photos from a holiday I cannot use because they are not jpg images. My computer is running windows 10 and I am looking for a program that can a) convert all mov files to one JPG or b brows frame by frame and then export one jpg image
