Suppose you made your video projects under a free account, but you used another account to purchase a premium plan. How do you transfer them to your premium account for editing and exporting? You need to use the Team and Duplicate Project functions.
First, make both accounts in the same team, then copy the video projects to this team. Now, these private projects have become team projects and can be copied to any team member's private account.
Detailed steps below:
Log in to your (free) account and:
1). Create a team.
2). Duplicate the project to your team.
3). Invite the other (premium) account to join the team.
Change to the other (premium) account and:
1). Join the team.
2). Duplicate the project from the team to this (premium) account.
