Hello.
I’ve been using the K1 on small video project and as it is my only camera, I’m happy with the results. Of course in the future I would love to get a Sony A7III, to get more filming options and more freedom in post, especially color grading. But with some nice manual M42 or K mount old school lenses as my Asahi 50mm 1,4 (33€ on ebay), he will definitely do the job.
And as it’s known, if you want a solid, life and weather proof, full frame, completely adapted for travelers/landscape/stars photography, under 2000€, just go for it!
If you want to see some exemple of what you can achieve, here are my videos:

Done with Pentax K1 in most cases, Mavic air for aerial and go pro for undermater/sport.
