Finding the right subreddit and asking there is probably a better approach if you want to maximize the chances of getting the plate 'decrypted'.

If it’s a video, sharing a few frames can help as well

To even get started on this you'd also need to share some contextual information like continent, country etc. I'd say.

Its in CA, looks like paper plates which follow a specific format and the last two seem to be the numbers '64'. Police should be able to search for temp tag with partial match and match the make/model. Was curious to see if any software could help though

There are photo enhancers online. But your picture is way too pixelated to get any useful info from it.

If you know the font in advance (which you often do in these cases) you can do insane reconstructions. Also keep in mind that it doesn't have to be a perfect match, with the help of the color and other facts (such as likely location) about the car you can narrow it down significantly.

Maybe if you had multiple frames, and used something very clever?

Looks like a paper temp tag. Other than that, I'm not sure much can be had from it.
