Clipbucket tweaking

Hello, I have some adjutements on a clipbucket website. So I am looking for someone who allready put his hand in this framework (running version 2.6) Tasks list : will be more precise 1- I’ve created a variable SHOW_Watermark available in watch_video. I want the player to read this and hide the watermark if not true (PAK PLAYER). 2- I’ve created a variable PUBLIC_UPLOAD in categories table. In the upload page, I want to show only those categories (not all). however, In the admin area, it need to continu to show all categories. 3- Still in the upload page, need to add produced_by and description already setup in the database. Only need to show on the form and save properly after uploadin a video. Thanks
