Issues with Adding Keyframes

[Eli Portell]

Hey there. I have been testing the use of getting and setting keyframes, along with trying to set the interpolation type of keyframes, but I'm running into all sorts of issues.

First off I have tried using this code:

               // components == "motion" effect on a selected clip

               alert(targetClip.components.properties[1].getKeys()); //alert 1

                targetClip.components.properties[1].addKey(time);

                 alert(targetClip.components.properties[1].getKeys()); // alert 2

When I do this, alert one returns one time object, and then I run it again and it returns two time objects, as expected. Yet, when I look in the effects control panel in Premiere, only one keyframe is there. I figured this was happening because I didn't force the UIUpdate, so i proceeded with:

                 targetClip.components.properties[1].setValueAtKey(time, amount, 1);

but still no luck.

I am wondering if I was using an incorrect time value, but when checking it against the sample code on GitHub, I saw that seconds should work. Either way I tried passing in time as seconds, ticks, and just the full time object based off of app.project.activeSequence.currentPlayerPosition(). I also tried passing in the updateUI as true, and that did nothing either.

I went through again and set a bunch of keyframes, none of which showed up in Premiere's UI, but I was able to go in and set the values of them and find them at the time spots I had added them in at. It seems to all live just in extendscript, but isn't being pushed to the front end.

Tested in both 2017 and 2018, on Motion and Gaussian Blur. Anyone had these issues or have any insights? Hoping someone does, seeing as this is in the public documentation, and I'm not even messing around in the QE space.

Just wanted to bump this up to see if anyone had the same results?

Does PProPanel's keyframe code work correctly, for you?

Strangest thing. Was experiencing the issues. Ran the sample code you linked, and then went back and ran my own code and it worked.

Was not able to isolate the issue again.

Perfect!

I think that's the coding equivalent of bringing the car to the mechanic, and having it stop making that funny noise, on the way.
