Hi!
I used a poly powerwindow which I moved around frame by frame.
After that, since the boarders where quite sharp, I added softness to the window.
I hoped that the Soft1 value is taken for the whole power window, but (also ok) it was also stored frame by frame... good. no issue... another million clicks away from success, but at least better fine tuned.

here comes the bug: the shown value doesnt change frame by frame, it always writes out the last modified value. Note, that in reality, every frame has it's own specialized value setting stored correctly, so it's just a GUI presentation bug!

The "softness window value" (if that is a thing) is adjustable over the entire clip provided a) auto-keyframing is not turned on, and b) you're in "Clip" mode and not "Frame" mode in the tracking palette. This has been standard in Resolve for many years.

well fine, then the bug is a different one:
I set a global value, but it is only stored frame by frame....

one or the other, the behaviour is buggy

I'm not seeing the problem, and this is a feature I use frequently. I agree that keyframing and power windows are not always intuitive, but it is something you can get used to and deal with over time.

Again, I just completed a 2-hour feature for 50 hours that had hundreds and hundreds of tracking power windows in 16.1, and there were no issues with tracking or softness or anything else. I generally don't use auto-keyframing, but I do use Frame mode frequently to hand-roto shapes when I have to.

If you want to upload a small piece of the malfunctioning project, maybe the users here can take a look at it. It's always possible there's a corrupted node causing a problem, and I have seen issues like this that could only be solved by resetting the node and starting over.

Hi Marc,
as requested, here is a freshly made test project, which shows the same behaviour:

<REMOVED>

What I did:
pulled a simple clip into an empty timeline
went to color tab, created a poly-powerwindow, added an alpha-channel, so you see the result
I went to tracker, went from "Clip" to "Frame" and changed the PW position many times to fit the clip.
Then I selected two arbitrary points in time and added some "Soft 1" in the "Window" section.
The softness fades in and out, so it _is_ definitely using the above set automation points.
But, and here comes the bug, the Numbers shown in the "Soft1" field are never updated and show wrong values...


regards
Mike

Checked it and it's fine. Use "Inside Softness" and "Outside Softness" and see how that works for you. I never use the regular Softness when I can avoid it, especially on a PowerCurve shape.

can you elaborate on your statement "it's fine" ?

Do the "Soft1" numbers change, when you step between frames? Because that's what I would expect to happen... but it doesnt on DR16.1.1

another way to prove the bug:
when you open the project, go to color tab. Click to a frame, where there is obviously "softness" applied.
The text will show "Soft1" is 0.00 --> well, that is wrong... it should be e.g. 13.36
when you now edit whatever value (even eg. Soft1 to 50), and then hit CTRL-Z, it will undo your edit... AND: it will correctly update the Soft1 value to whatever it should have been before (e.g. 13.36)

That means everything works the way it's supposed to. But I only use Inside Softness and Outside softness. Those are extremely valuable modes that I use on many, many projects.

A regular round/oval power window works the same way, though without in & out softness -- no malfunction. What you're describing is basically Frame (tracking) mode, but in Clip mode, it will set a uniform value across the entire shot. There is a bug where if you have different softness values on several sides of a Powercurve window, it will reset them if you try to do an overall softness change, but I understand the logic in that.

It seems to be a UI display bug. If you select a different clip and then go back to the clip in question, then the value displays correctly for the play head position.

...that's what I say
