Backup-videos

I was just wondering as I have to change onto a new iPad, whether the videos that I have taken on IDOCEO and attached to students as evidence of their work save when I do a backup to dropbox?

It depends on whether you were storing them inside iDoceo or in your iPad's camera roll.
Give it a look on iDoceo's main screen settings (gear icon) > Image&Video

If you were storing them in the iPad's camera roll they are not included in iDoceo's backups but will transfer anyway with an iTunes backup/restore into the new iPad.

You may move them into iDoceo so that the backup includes its.
