I know, but it's not smart since there are some After Effects transitions.
I mean, if I stretch the layers, the transition just goes slower.
But in your case it will be just drop in framerate.

<p>I don't know if it works, but you may add a marker on each layer when the transition without stretching starts pressing this key: * </p>

<p>So when I stretch the two chosen layers, they do stretch together, but the collision point shifts so I need to correct it manually.</p>

<p>How can I simultaneously change the length of the layers without messing the scene?</p>

It works the way it is supposed to. You just need to realign the layers afterwards.

Well, I know. I'm just hoping there is another way to adjust the length of the composition.

I'm having a play and a look at documentation to see if there is another way...

Seems like a job for a script.

How can I simultaneously change the length of the layers without messing the scene?

I don't know if it works, but you may add a marker on each layer when the transition without stretching starts pressing this key: \*

Then, I think the markers should be paired with the original frames and then you just have to match them in the timeline again.

Sorry if this doesn't work or there's a better way, it's just an idea.
