Road to Hell - Changing FPS

Reproduction Steps

Simply changing the FPS of media (and adding pitch) manually is more complex than it needs to be.

Problem:
Change 23.976 to 24 and normalize audio

Solution:

[23.976 to 24]
profile-cond=container-fps=23.976
speed=1.001001
pitch=1.001001
audio-pitch-correction=no
af-add=rubberband=pitch-scale=0.999,engine=finer
sub-speed=24/23.976 (this value will work with speed/pitch too ?)
sub-fps=24

Proposed solution:
If mpv can handle conditions, how about the following:

fps-cond = 23.976 = 24
audio-pitch-correction = hd
sub-??? = video-out-fps

Additionally it would be nice to hold one frame longer instead of repeating it. hold-cond = 24 = 2 for example would output 24 frames in 2 seconds instead of bobbing the output to 48 frames (reduces CPU/GPU usage)

Also I want to mention that the manual is very confusing on this topic, see image attached:

Expected Behavior

Simple and straightforward

Actual Behavior

Not simple and straightforward

I assume at 1.2x normal speed just means at 1.2x times the normal speed, i.e. sped up by factor 1.2 😆

What two words can change 🤯 Actually I read that sentence 10 times and questioned my sanity
