i created a loop video using blender and submited to the adobe stocks but it rejected. reason for it is missing generative ai flag. but it isnt a ai video. what should i do?

Blender is not an AI program itself, but it has Very strong through third-party add-ons.

It’s not an area of my expertise, but I know the loop needs to be truly seamless.

This is the biggest potential issue is highly generic loops like basic water ripples and clouds often get rejected for being too similar to existing content. And like with still photos, moderators sometimes reject them saying they are AI when they are not. 

I know it sucks, but I would try submitting as AI (if the loop is perfectly seamless)

Good Luck!
