Presently, replacing a thumbnail image for a Studio video requires uploading an image file from the local computer. In nearly every conceivable case, the desired image will be a frame from the video in question. So a user must play the video, pause it on the desired frame, capture the image with some sort of screen capture utility, save that image to a local file, and then upload it.
It would be tremendously helpful to be able to scrub through the already uploaded video to the desired frame and click a button to use that frame as the video's thumbnail.
