Hmmm, I’m not sure I understand…
A large explosion every second has units of power, not energy. So to me this is suggesting that the train is putting out power equal to its kinetic energy per second. That’s certainly not the case — it implies that the train is powerful enough to accelerate to the speed in 1s, which is definitely not true.
But that’s just my interpretation.
I just want a button that rewinds 10-15s, turns on subtitles, and then turns them off when it catches up again. It’s a pattern I do manually with some regularity.
I suppose with Jellyfin/OSS, this is something I could implement myself if I was so inclined…
