Social Media Video Ad Templates (for promo NOT for socials)

I’m looking for complete ads for social media (in both rectangle and square formats) that show off square social posts and story designs. Right now, the market is full of animated social posts you can post individually to your socials as a post itself but I’m looking for a video template that will help promote that I make graphic designs for socials.

I always download a template, thinking it’s the ACTUAL template of the video thumbnail I just watched and it’s just an animated social post :frowning_face:
