I'm Ziling, I'm a photographer and also interested in this topic. Absolutely, AD patients face a lot of unfair behavior. I think this is a useful method that plays some short videos to change many people's ideas and opinions for AD patients. On the other hand, you also could consider that use more Social Media Platforms to develop videos, such as Tik Tok, Instagram, and Facebook. In my opinion, I think short videos would be better than long videos because most people don't want to spend too much time to focus on videos they are not very interested in it. The length of videos should under 1 minute and try your best to involve more contents.
If you need any technical help, welcome to contact me.
