Fireworks and 4K

Fireworks are not my thing at all but a local glossy rag for which I, once in a blue moon, take photos of undemanding stuff (gardens, architecture etc) has suggested I cover our local firework display for them. They must be desperate! 
I just wondered whether anyone has used 4K video to take fireworks and pulled 8Mp stills from it?
The quality needs to be good enough for printing obviously. Photos will be up to 8" longest side.
Any tips appreciated. I'll be using an APS-C mirrorless camera in case it's relevant.

I probably wouldn't do that. You could take some with the video just to see how it comes out and back it up with some stills. After all I don't suppose they will publish that many so you'll have plenty of options.
Oh, and use a slower shutter speed, fireworks look better with a bit of motion blur.
Good luck.

I was just wondering if anyone on EPZ had actually used 4K for firework photos. It seems not from responses so far.
Oh well, I might well be a pioneer!

There is a model that lets you choose half a second, I don't know how it works. But normally when you shoot video, instead of stills you can't have a longer shutter duration than the the time that frame is the active one. So if 1/25 sec is as slow as you can go then you are shooting fireworks at a speed that doesn't allow for coloured trails etc. You will be able to cherry pick frames later but I think that even if the video looks good, you'll be disappointed when you hit pause.
Notice this video, looks okay when playing but hit pause, not like a decent photo really?
