I need a single replacement, to place in GUI, that categorises both "document" and "video". I need to place in my website interface to replace:
"Upload a document"...
"Upload a video"....
Any ideas ?
OK - so I'm going to play a slight joker card here. And you may not realize it but you're giving this answer away in the question.
I'm totally agreeing with @PhilipW and @Baa along the lines of just
Upload - but with a simple twist which speaks volumes...
Upload with an ellipis - which tells the user that there is something in the user interface which is an extra step between pressing the button and completing the action.
It hints that you don't need to care what it is that you are uploading before you click the button, because you'll have a chance to sort that out on the next step. It's equivalent to
Save As... where you choose the format after hitting the button, or
Print... where you choose the printer after clicking the button.
Of course that depends on your user demographics, but most people these days understand what a File is since that term has been used forever.
Simply "Upload" could work as well.
I would not recommend using only an icon for the button, however. There is no well-recognized symbol to depict this type of action.
