i could be wrong here, but it looks like some instance of Video_Params is used as a argument to some random variable. For HMC to work, the arguments to the random variable have to be differentiable.

I removed the matrix v of type Matrix{Real} from the Video_Params struct so that v would be a separate argument to random variables. Now I have a new (slightly different) error:
