I have 4 videos on my ipad that I have uploaded to the cloud and want to delete from my ipad but for some reason when I select the delete bin does not work.
If they were synced to your iPad using iTunes, you can't delete them on your iPad. You have to connect your device to iTunes again and deselect these videos.
If you tried to delete the videos in the Video app (in case they were not synced), try this method: go to Settings - General - Usage - Storage - Video. Select "Edit" at the top right there and delete them this way.
