Thanks for your response,
I should have been clearer and should have mentioned that I'm looking to slice/blade/chop off the left and right side of the storyline. That way, it will be become narrower horizontally and easier to work with. Sorry for the confusing.
The attached file shows my story line in the Angle Editor. The actual footage is about 9 min. long while the total length of the time line is well over an hour.
While testing to see if I had overlooked something using the "light switch" and command -/+ to zoom, I came across some stray single vertical lines in orange. I thought I had solved my problem. But, I can't grab them and delete them. They seem to only show up when I zoom in closely, otherwise they are not visible. I have attached an image of that as well.
I hope you can see the details in my screen grabs.
Thanks
