Inside the frame class it is possible to check if a frame has a Timeline Marker attached to it, check its note, start frame and length, but you cannot manipulate markers.
Could you please expose the API to allow users to create and edit Timeline Markers via script instead of only being able to read from them?
We would like to use this feature to add a Timeline Marker to a frame when the frame has ease in or ease out. When a scripting button is pressed it will check which Keyframes have ease in or out and adjust the Timeline Markers accordingly.
Thanks for your help.
