  Let's say, I want slow motion of my dog
  I will record him with 2 cameras, one will be set to 60fps, another to 50fps
  
  both of them will be slowed down and played back in 24fps timeline
  
  Will original 60fps fotage show my dog in slower speed ?

Answers.Text: "Will original 60fps footage show my dog in slower speed ?" — of course. It will play at 24/60 = 0.4 of its original speed, while 50fps video will play at 24/50 = 0.48 of its original speed, presuming that you slow down the original video without losing frames or creating fake frames. Whether the difference is significant or not is totally subjective.

ThreadText: # 60 fps vs 50 fps in 24 fps timeline slow motion difference
  
  (Asked by: username_0 on 2019-08-18)
  
  If my math is correct, shooting 60 fps, playback 24 fps will allow me 2,5x slower motion.
  
  Shooting 50 fps than should give me about 2x slower motion.
  
  Is that difference significant in real time, or it's just in theory?
  
  Will 60 fps bring “slower” slow motion over 50 fps on the same 24 fps timeline?
  
  Thank you.

  The difference in the speed of playback *up to 5 %* is considered as *tolerable, unnoticeable.*
  
  By this rule of thumb 60 fps compared with 50 fps are *too different (20 %)*.
  
  As an example of a tolerable difference is a common case of playing back a movie with 24 fps on TV set in Europe with 25 fps (4 % difference in speed).
