How to Time Stretch / Time Remapping a composition without messing up key frames?

I make a composition "Master Composition"

I make a composition "Car drives".

In that composition the car picture disappears by going from Frame 50 Opacity 100 to Frame 51 Opacity 0 (so it appears immediately).

I put Car drives in Master Composition.

Car driving is too slow.

So I use Time Stretch or Enable Time Remapping and I speed up Car driving composition.

PROBLEM!

There's a frame where Car is Opacity 50.

It's no longer:

Frame 50 - Opacity 100

Frame 51 - Opacity 0

But what I see is:

Frame ?? - Opacity 100

Frame ?? - Opacity 50

Frame ?? - Opacity 0

Basically I now have a frame where the car is in Opacity 50 and I definitely don't want that!

How do I fix this? I just want to speed up the composition AS IS.

"Time-remap inside the comp, apply the opacity animation in the parent comp."

I'm not sure what this means exactly. Apply the opacity animation on [Doos1 4e laag] in the parent comp? How?

I'm not gonna test it but my assumption is that causing an error with the opacity by crossing the frames over each other.

Think about...you have two key frames one frame apart frame 50 = 100t frame 51 = 0t. Then you apply time remapping to make everything faster but you can't make something happen faster than one frame. It's commons sense.

Imagine you are working directly with opacity frames (one frame apart 50 & 51) and you decide you want the opacity to happen faster. So you take the key frame at frame 51 and drag it back to frame 47. ???? Now you've moved your second key frame before the first.

You have to do the opacity so it is not being effected by the time remap.
