I have two questions about what is going on in the screenshot above and one other:

1. - Why are two clips "greyed out?" Neither is disabled and nor is the track (notice clip to the left is NOT greyed out.) It is trying to tell me something, but what? Seems to happen when I split a clip that already has effects on it, but it's also seemingly random as to which sections are greyed out and which are not.

2. - What is the little blue dot widget on the IN edge of clips that have effects applied? You can see in the screenshot I am hovering over the dot and it shows the value of the Tilt X parameter of Crop, Scale, Tilt. I can drag it up and down to change that parameter. That's all I know. I have no idea why it's tied to that particular effect (there are 2 others) OR why it is tied to that parameter over the many others available. I can find no way to change it and no documentation whatsoever after hours of reading and experimentation.
I would really, really, really like to disable this feature because it causes me to inadvertently change some random effect parameter when I drag the IN point on a clip. At the very least I would like to know why it's there and how to control what it is tied to.

3. - Why would it be impossible to disable keyframes on effects? If I disable keyframes on an effect, regardless of whether I have actually assigned keyframes or not, when I click off that clip to another and then back again keyframes are re-enabled! Seems like a bug, but I want to rule out some unknown circumstance where this behavior might make sense.

hi! the number 3 is a bug: https://invent.kde.org/multimedia/kdenl ... ssues/1394

the 2 dots on top left or right of clips are using to automatically add a fading effect... (the effect is added when moving dots)

Thanks for confirming that bug!

This is NOT what I'm talking about, I am aware of the fade dots. This one is bigger, blue (using Breeze Dark) and slides up and down the left edge of the clip causing a random effect parameter to change value. Look closely at my screenshot where my cursor is.

Ok, sorry you are right.. i was not able to see the dot because my effects are not placing the dot on the half height....
opened an issue for this : https://invent.kde.org/multimedia/kdenl ... ssues/1522

On my install it *is* placing it on the half height (which I use 99% of the time), but unless the effect parameter places it pretty much dead center, it's invisible. Some percent of the time you will accidentally move it while resizing the clip regardless of whether you see it or not. Which is the whole reason I even noticed/discovered it. I will grab a clip to resize and as I drag nothing happens, but because my mouse slightly drifted up or down it changes whatever parameter is randomly assigned to the keyframe. I only noticed because I happened to have the effect stack visible and saw it happening. This has to be silently driving people crazy! LOL
