Cannot set starting time for a layer I Sometimes work sometimes not

[Moira24]

Hi there,

I've been trying to make watercolour effect and in one step, I need to duplicate the layer, reduce the opacity and drag the starting time backward a little bit for the layer on the top, to make sure it has the 'bloom' effect, just as below.

It worked twice, but the thrid time it just didn't work. When I played it, the whole thing just lit up on half-sec key frame because of the increase of opacity. I'm not sure if the software not responding or if I did something wrong. Anyone have idea what the problem might be?

The effect I got:

 

Many thanks,

Moira

If you work with mattes of course you have to duplicate and manipulate those layers just as well. Even the new system introduced in AE  2023 doesn't change that, in particular when you change the timing.
