John Dikmen PRO 1 year ago I just upgraded to a Vimeo Pro account and successfully uploaded my first video. The only thing I am having trouble with so far is "Choosing" a thumbnail. I get a set of several preselected thumbs and also see a "Choose" and an "Upload" option. When I click choose it brings up my movie. I click Play and it starts playing until I hit pause. I then tell it to save that frame as the thumbnail, then I get an animated "Processing..." dialog. I have tried several times, but it never stops processing - once I let it run for an hour? Any ideas?
