Looking through AE UXP API, it’s pretty much the same with what we have in ExtrendScript.  
In terms of keyframe handling, we can only use `property.keyInSpatialTangent()`, `property.keyOutSpatialTangent()`, ect. Which is not so convenient to use when I need to copy/move the keyframe to another position in time.

To do this, you have to do a lot of things. You have to check all those properties and values in your old keyframe, then create a new keyframe and apply thoes properties and values to your new keyframe, which is a lot of works. And this method also comes with limitation, you can not work with CUSTOM\_VALUE\_PROPERTY, because you can not read and write its value.

So I am wondering, if we can get a Keyframe Class/Object, `const key = new Keyframe(property, index)` and on this class, we have `key.moveTo(time)`, `key.copyTo(time)`, etc. Such a class would be a great welcome, it saves lots of work and can go beyond the limitation I metioned before.

So, can we expect to have such features in uxp?

A Keyframe object would definitely be useful, although I could see potential conflicts when moving a keyframe to a time where another keyframe already exists.

I’d also propose adding these methods:

- valuesAtTimes(times, preExpression)
- removeKeysAtTimes(times)

We already have `setValuesAtTimes()` which saves a lot of API calls, but it would be great to retrieve values in bulk with `valuesAtTimes()`. Removing keyframes also requires looping individual keyframes so `removeKeysAtTimes()` would be very useful.

Calling `valueAtTime()` 1000 times can leave After Effects unresponsive until it finishes, even in UXP. A bulk `valuesAtTimes()` method could significantly improve performance and avoid UI freezes.

A Keyframe object would still be useful for preserving interpolation, easing, tangents, and other keyframe attributes when moving or copying keyframes.

> when moving a keyframe to a time where another keyframe already exists

In this situation, I think it’s fine to overwrite the existing keyframe.

And methods you proposed are also great, hope they can be implemented as well.

Thanks for raising the feature request, @MikeSevigny and @dongxi !

We will consider this request for our roadmap and will get back to you if we are able to prioritize it. 🙌
