I have a number of ideas in the pipeline to keep Him interested (videos of myself doing non-sexual things, for example), but I am worried this might not last for the long term.

First of all, don't think you have to do things just to appease him in the hopes he won't leave.
It's not a good thing to think that way. You shouldn't have to compromise yourself for another.
I personally have the same problem as well. Since I am not able to have a physical relationship at the moment, I constantly worry that I will not have enough to offer him and he will eventually lose interest.
I was called out on it once, and was told that if I didn't already know where my place was, maybe it wasn't my place at all to begin with.

So no amount of advice will really solve what you worry about the most. It is up to you to determine how comfortable and safe you feel in your own relationship.
Keep doing what you are doing, but don't think that you are a commodity that can be discarded at any time.
Have you discussed this with your Dominant? It is important that you do because you will be able to alleviate those fears you have and you will be able to enjoy yourself more without having to worry about pushing your own boundries.
