Timeline rescaling
I am composing some simple animations. In order to keep the timeline manageable, I am editing 30 second clips at 15fps which means my animation contains 450 frames. When all of the timings are perfected, I then select the entirity of the timeline, which can feature up to 20 layers or so, and then stretch to 900 frames (when the marker shows that you have exactly doubled the length of the timeline) and then modify the file to run at the 30fps the client requires. I don't know why, but this used to work just fine. Now, when I do this, all of the timings in relation to each other are, in many cases, way off! Have been using the same version for every project I've worked on (21.0.9 running on Mojave 10.14.6) but this has only just started happening. At my wits' end.
