No Publication Update
OptiPub does not allow for Videos to have their Publication ID updated after creation. This is done to alleviate issues with assuming ranks.
Updating Ranks
It is up to you to sync the ranks of the Videos before submitting the request. OptiPub does not assume how you would like to rank your Videso. It is recommended to update all of the Videos related to the same Publication at the same time to avoid duplicate ranks or inconsistent numbering.
