honestly it's kinda wild people are still doing these manually. like, the "before & after" split image thing, that's just a standard trained model pattern now. we've been pushing variations of this for internal design systems for over a year. seems like youtube creators are just catching up to what's already table stakes in product imagery.
while the idea of AI-generated thumbnails for "My 30-Day Fitness Journey" is efficient for creators, I question the broader ethical implications. in korea, policy discussions around deepfakes and AI image manipulation are very active, especially when dealing with personal transformations. how do we ensure these AI tools don't inadvertently promote unrealistic body image ideals, particularly if the "after" image is subtly enhanced beyond actual results? it's a concern for APAC regulators.
ooh, this 'before & after' prompt is super useful! can totally see this for my own content. but i always use canva to add the text myself after the AI image, it's just cleaner.
