I have had a further play with yours.
I have added an extension to get the current Scene Element. from the Extension Page
Doing this we can query the individual scene for it’s video.
What this means is we can use a single JS function that syncs the ‘Main Timeline’ for all the video scenes/layouts
Each video ‘Main Timeline’ now has the jump to scene action. And we do not need a separate timeline for tracking.
@hyping I have put it on weTransfer hopefully this link will work
Check back here in a few mins…
