When i try to replace video using the PHP API, thumbnail with color bar do not change !! Can i replace thumbnail with one another using PHP API ? thanks. Lien: https://vimeo.com/117603467
when i try to share it on facebook or other websites the thumbnail that appears is still the color bars of vimeo....
Can you link to the video(s) that aren't returning thumbnails? Are you using the API to get thumbnails?
