I didn’t find anything on how to upload the file. I know I have to upload videos via FTP, but is it as easy as just upload the .mogrt file or do i have to export a video showing the graphics? And if so do I need to upload a zip file with the video and the .mogrt file?
please have a look at: Stock Contributor User guide / Motion Graphics template requirements:
"...Motion Graphics templates are a new content type that we are not currently accepting through the Contributor portal. If you would like to submit Motion Graphics Templates for consideration or for more information, reach out to us at email@example.com. ..."
