labeling videos

There is no option to "change" that. The tool suite of IMDbPro provides for the uploading and removal of video gallery items intended only be demo reels about the specific subject of the corresponding name page, and the control of the presence of the content is had by IMDb member account through which the demo reels were uploaded to begin with. (Also, IMDbPro subscribers can only upload demo reels to name pages that they've claimed.) Other types of video gallery item, such as trailers, are uploaded directly to title pages by studio partners, and may show up the video galleries of people who have credits in the movies documented on IMDb and represented by particular video entries.
