If I upload a video in the mp4 format Wordpress automatically creates an image called Filename-mp4-image.jpg which is a screenshot of the uploaded video. This is fine, but what I don't like is that when I select an image in a custom post type (where images is only allowed) the screenshot shows up too.
Is it possible to disable the screenshots from showing up in the image media browser? And only use the screenshot for the file itself (when you look at the MP4 file under Media)?
Thank you!
