Ask HN: What are the cheapest video streaming options available?

My Next.js production app receives a lot of views, and there are a couple of videos on the page that get played. I am looking to offload the videos to other streaming providers, as I cannot use Vercel for video streaming due to the high bandwidth costs. There are many video streaming providers available, such as Mux, Cloudflare Stream, Cloudinary, Fastly, Backblaze, and Vercel Blob, among others. I have looked at their pricing pages, and it's not obvious how to project costs without actually trying them out. Moreover, I'm concerned they might have some hidden fees not stated on the pricing page. I don't want to end up with a surprisingly huge bill. What has been your experience with these video streaming providers? Which one has been the cheapest in your opinion?

Fun fact: In <video/>, using `preload="metadata"` doesn't guarantee that the whole video will not download. My allocated bandwidth quota was 75% consumed due to this bug.
