Realize Policies require that video creatives include the name or logo of the company promoting the content. It seems that your video creative does not meet this requirement, or may include content without appropriate copyright permissions.
How To Fix
Make sure that your video creative is compliant with our policies. Here is a non-exhaustive list of actions that may result in this type of rejection:
The apparent promotion of anything that does not include the name or logo of the company promoting the content. Your video creative must clearly represent the advertiser and their product or service in the video.
The apparent promotion of anything that infringes upon the intellectual property rights of the relevant party in the video creative. Make sure that you provide us with the appropriate permissions for your third-party content.
