Listen to timeline changes via scripting

[Evgenii Eth]

Guys I am pretty sure that the answer is no, but just asking - is there any way to listen to changes on timeline in premiere pro? I need to change label color whenever clips are moved within tracks

Maybe there are some workarounds or is it possible with plugins instead of extensions?

Here is the list of all Premiere Pro events. You definetly can see if item was moved in timeline:

I'm not sure if you can change label color in timeline. This is only possible for projectItems.

Ivan's right; you cannot change the label color of an existing trackItem.

Thank you for the confirmation, but is it possible to do so with sdk?

[Bruce Bullis]

I'm sorry, I don't understand the question; is what possible, with the SDK?

He's also right about the available messages; the PProPanel sample shows how to handle the onActiveSequenceStructureChanged and onActiveSequenceChanged events.

Sorry for not being clear, I meant is it possble to achieve it with plugins, not extensions that use extnedscript API

I feel there is should be a workaround as rendertom has achieved this in his Labels ppro 2

[Bruce Bullis]

No C++ plug-in APIs have control over label color of either project or track items. 

If Labels PPro 2 is changing the color of existing trackItems, then rendertom is doing that without the benefit of any API call to change trackItem label color. 🙂

I don't think Labels Pro 2 allow to change label of trackItems. It only works if user have "Show Source Clip Name and Label" enabled. Basically it changes projectItem label and then this is reflected in timeline, because of "Show Source Clip Name and Label" setting.

Yes propably this is how it is done, thank you for pointing on that 🙂
