Add Keyframes to Adjustment Layers using Api

[Imkindofabigdeal]

Hi folks

Is the above possible? I get that adjustment layers are basically stills and don't have the same properties as clips, but I can't seem to add Keyframes to properties programmatically.

Seems to be an issue with finding the timecode or frame to add the keyframes to. It seems to adjust the value of the first frame over and over but not add a Keyframe.

Works fine on clips.

Thanks

You're right that AL's are clips ... or 'media'.

They are simply a 'holder' for effects.

So you can keyframe effects in an AL, when on a timeline, but you can't add keyframes to an AL itself.

Thanks for your reply.

Just to confirm, I've added the AL to the timeline and I want to add keyframes either to one of the built in properties, eg scale, position, or to an effects property eg the transform effect.

I can adjust the values using ComponentParam.setValueAtKey(), but ComponentParam.addKey() doesn't work, and setValueAtKey() seems to just affect the first frame. I suspect it's because ComponentParam.setValueAtKey() takes a Time parameter, and the AL doesn't have the same time properties as clips.
Does that make sense, is there anyway around it?

Hi Imkindofabigdeal,

Can you send us a snippet of ExtendScript that demonstrates the issue? 

[Imkindofabigdeal]

I've sent you a snippet. When run on two clips in a timeline, it will read, manually added, keyframes from both clips, but the same code will only add keyframes to the media and not the AL

Thanks

I can reproduce the behavior. 
We're tracking it as DVAPR-4259779, and will keep you informed of any progress. 

It's unlikely we'll be fixing any ExtendScript issues; our extensibility efforts are focused on UXP extensibility. However, we will confirm whether this behavior is present in UXP, and (should it not be) will attempt to resolve the issue, there.

you will have to keyframe Transform Effect values for ALs.

When it comes to coding and API related stuff, then better send 

the code to Bruce as requested.
