After students submit their projects to the assignment, instructors can combine those submissions into a new project, edit it, and share it within or outside the class. Please follow the steps below to combine the students' submissions into a project.
Select the class.
Select the assignment and click Review progress.
Click the Review video option.
Select the students you want to combine and click Combine.
Adjust the order for how the video from each student will be placed on the timeline by drag and drop or with the arrow on the left side. Click the Combine into project button to start combining them.
You can now start editing the combined project the same way as any other project.
