While storing videos every quality option (144p, 240p, 360p, 480p, 720p, 1080p, 1440p, 2160p, the last of which depends on the original video's resolution) like YouTube and Dailymotion would be expensive, I suggest at least a 240p (or 360p) watch quality option which could actually reduce costs because of a part of viewers choosing it rather than the full original resolution. 144p would often be too low to be watchable, but 240p is just enough for many videos.

Sometimes, I am totally fine watching at 240p, and it would reduce stress on data plans for mobile watchers, speed up downloading for already throttled users, as well as , which is useful for seeking through long videos.

If it is stored as a single file at the original resolution only, video platforms (YouTube, Dailymotion) would need ravenous computing performance to convert it down in real time.

Doesn't take much power to down res in real-time.

But I guess more than streaming the unconverted video. Needs more bandwidth, but I think that is less expensive than power needed for real-time downscaling.

High bandwidth requires more energy from the server, and for the route as well. Scaling requires more energy at the server only, but again it isn't as much as you think.

Go to MSpaint and lower the resolution of a large picture vs raising the resolution; observe which one takes longer.
