I just uploaded a new album containing some videos. I've noticed that the poster image thumbnails are not being watermarked as videos. I checked that this option is selected in class-video plugin and also checked and videos uploaded months ago are properly watermarked on their poster thumbnails but these new ones are not being properly identified and then watermarked. I am using a modified version of Basic Theme but I switched over to Basic to see if the same is true and even using the real Basic theme, there are no watermarks on recently uploaded videos.
