I just checked and the frame rate is identical between v.1.0 and v.1.4, approx. 24 fps
My Panasonic Ultra HD Blu-ray player flags the metadata of 4K77 2160p v.1.0 as 23.976 fps. I cannot se any reason that the 1.4 is any different. But I will check it out soon.
Thanks - I know it shouldn’t be 60fps, just wondering why none of my Mac media players can tell me what the frame rate is. Interestingly, using Handbrake “same as source” to re-encode gave me a 23.97fps file, so mystery (probably?) solved, but it doesn’t explain why, for instance, when I try to create a new file with my own settings, it only offers me frame rates in the 30/60 frames world.
Anyway, 1.4 looks great!
