Are you sure it doesn't indicate 1000?
I am not using the trial version so I am not sure what it states, but it is not referring to how many 'times' you can use vMix.
This is the number of Inputs vMix is capable of handling.
That may be the only limitation of the Trial version (I do not know) but the "licensed" versions range from 4 to 1000 inputs (or 2 to 1000 Capture inputs)

The Trial version is for testing the software to verify that it works on your system and will do what you want or need it to do.
It is full featured (but may have a 100 input limit, which BTW is likely more than enough for even the most elaborate of set-ups).
Enjoy your trial period, test to your hearts content, ask questions and/or make requests, I am sure you will discover vMix to be a very powerful piece of software that can accomplish just about anything that would otherwise cost you tens of thousands of dollars to do with conventional television broadcast hardware...
