At work, we had video content with "ai generated" now shown in an eponymous Teams channel. Now no one viewing the video knows if just the image, or the project logo, and/or the voiceover was AI generated but is very confused on that upon seeing the label.
Skip the labels. Photoshop and "the trainee did it" existed for 38 years already, and respectively for many more years now, and have about the same reliability.
