When adding a VOD, I can not find the option to input a name for the VOD.

The VOD name is not visible or editable during addition. After adding the VOD, please navigate to the settings page for the VOD. From here, you can edit the VOD name located near the top and save by clicking the button on the top right.

The file name for the VOD file will be used as the default (ie. A VOD file with the name "test.mp4" will have a default VOD name of "test.mp4").
