It is also possible to copy videos (VOD assets) from a different Workspace to the current one without reuploading the original again.
Your user account needs access to the Workspaces you want to copy from. You might need to check with your Organization admin.
In the Videos overview click "Add Videos"
Click "Copy from workspace"
Select the videos you want to copy
You can add videos to the copy list by clicking on them. You'll see the Workspace a video belongs to on the right.
The selected options will be applied to all videos. If you need to set different options for some clips, add them in a separate batch.
