Hi Scott,
Thanks for reaching out to the Adobe Stock community.
Videos are only available under Enhanced license and can be purchased on-demand or using credits from credit packs. As per the requirements you have stated above you can use the video from Adobe Stock(purchased under the Enhanced license). A wiser/safer approach will be to use some clippings or background of the video footage for the film you are creating. Additionally, credits are needed to be added if posting this footage on social sites.
Under no condition, the videos(unmodified) can be uploaded to YouTube, that includes publishing videos as unlisted- since the video is stored in the YouTube database which can be accessed.
For more information, you may also refer to Stock Licensing & terms FAQ: Where can I find the terms and licensing information for Adobe Stock?
You may also contact our support team Support FAQ: How can I contact Adobe for support? for further assistance.
In case you are unable to reach our support through the above-mentioned link, please see Contact Support FAQ: Unable to reach support through the "Contact US" link
Hope this information helps!
Feel free to update this thread in case of any additional questions.
Regards,
Twarita
