If you're looking frame by frame trying to read a plate, one thing you can do is stack a series of frames up to get a better signal-to-noise ratio. Basically, deform/align up the characters of the plates and adjust the transparency of each image in the stack so you can see them all. Weight the least-blurry images higher than blurry ones if you want to get fancy.
This tutorial is for astronomy but the principle is the same:
Photoshop/free alternative is good enough for shift-and-add stacking. Bit tedious though.
I'm far from an expert on this, I know there's a few astrophotography people on here who might be able to offer more insight if there's a serious incident

Probably also possible to do some deconvolution unblurring stuff
