Alright, after spending some time reading the Vegas API without much luck, I've decided to ask a question here:

As the title says, I want to modify a value of a specific video fx keyframe in vegas using a script.

Here's an example: I want to modify the value of the selected keyframe to a different value.

I've checked the vegas api, but there doesn't seem to be any fields or methods that relate to modifying a video fx keyframe value.

Is it actually possible to do this using a script? If so, how can I do it?
