17fps is totally fine, if that is the case. In the video it looks much more aggressive. I bring some of mine down at 25 fps.

Will an altimeter, or flight computer of some sort tell me the rate of decent?

Yes, Altus Metrum Easy Mini - quite cost effective, doesn't require a special cable (just regular USB) and the software is very cool..

Example Graphing below:



Also it's very small, very light and doesn't need a large battery either.

Most, but, not all altimeters have some logging based on barometric and temp data. I always do post flight analysis of my altimeter and tracker data. It indicates velocity, but, I take it with a grain of salt. Although, I have always found it to be reliable data to dial in my recovery choices.

There are a few good options for electronics. If you just want flight data a Jolly logic 2/3 or micropeak altimeter by altusmetrum. Congrats and welcome to L1.
