After hitting a blank wall myself and reading this post :
I saw that the conclusion was that this is not a bug but a feature.
When a preset is selected, the “home made” keyframes are gone.
However… something does not sit right with me…
So I have a scrolltext and it scrolls as it should.
But unfortunatly there is no dropshadow possible (? feature request ?)
So I copied the transparent layer with the text in it, changed the color and the opacity of the one in the lower video track and had ShotCut convert the simple keyframes to advanced keyframes and then I changed the X-Y position in the converted keyframes. Text inclusive shadow was perfect… Until I clicked on the lower transparent that holds the shadow.
But here is the weird thing. In order to make the shadow appear, I changed the both the X and Y position to X+2 and Y+2. But after ShotCut removes all the keyframes the X-position remains X+2 and Y is reset back to Y ?!?!
In my humble opinion, ShotCut should NOT remove the keyframes. Specially coz it literally asks if you want to convert the keyframes. I think it should change the preset to “Custom” or something like that and keep the keyframes ShotCut made when you said “Yes” to the question :
Confirm Removing Simple Keyframes ?
This will remove all simple keyframes for all parameters.
Simple keyframes will be converted to advanced keyframes.
Do you stil want to do this?
YES - NO
So my workaround was to copy the transparent layer and in the one on the lower track I again did the color/opacity trick. Then I added an extra filter “Size, position & rotate” and with that last filer I did the X+2, Y+2-trick.
Anyway… This is my US $ 0,02.
Perhaps I missed or misunderstood something. If so, please tell me what ?
(English is not my native language so hopefully I did not make people mad)
Oh and before I forget, I work under Windows 10 with ShotCut version 22.04.25
