Hey Mike,
I have tried O-Rings (the smallest mm that I could find.. they were red if that helps?) and soft landing pads.
I far preferred the soft landing pads, they provided a very smooth experience without bottoming out.
The O-Rings prevented bottoming out I found, but they have a bit of 'bounce-back' / it wasn't really what I was looking for.
The pads are a bitt of a hassle to maintain if you like to clean the keyboard every so often imo, whereas the O-Rings basically just sit in the same position on the key.
I hope my experience has been helpful.
What is the nature of the videos you will be doing Mike? I am a comp sci under grad and am always on the look out for good learning resources
