I’m looking for a way to start a video based on the scroll position of the video on my artboard. In your post https://principleformac.com/posts/principle-four.html you say that video time can be controlled by a driver. Could you please explain how that is possible or maybe even share the original file, so that I can see how it works exactly.
Create a driver like you normally would for “Media time” and then click the “media” button in the properties panel to control the video time and add keyframes for it to the driver.
