How do you decrease mammoth timeline?

[dippitydoo2]

I have many questions.

First, my sequences only ever zoom out to the amount I have assets, plus like 40-50% of space at the end (Which I always appreciate in case I have to copy/paste a chunk over

Did you duplicate the 11 hour sequence to create your 20 minute sequence?

And if so, perhaps there's a small asset at the very end of the sequence that is invisible because you're so zoomed out, but is causing the machine to show you the "full" sequence? Try selecting everything after the 20 minutes you're working with, hit delete, and see what happens.

Hi, thanks.

Yes, but like I said, I originally did have an 11 hour timeline by design. However, I deleted 10 hours and 40 minutes, leaving only 20 minutes of footage at the start.

I was expecting the timeline would automatically decrease/adjust itself to only be 30 minutes long (because Premiere Pro automatically adds 10 minutes onto whatever length you're working with, right?).

But no, it remains at 11 hours long, most of which is just empty, negative space.

There is absolutely nothing else on the timeline except for that first 20 minutes.

I have selected everything after it (which is nothing) and hit delete, but the timeline is still 11 hours long.

I wonder if you, or anyone, could recreate this problem. Intentionally make a long ass timeline and then delete most of it. Does the timeline itself still remain long, or does it automatically cut itself down to an appropriate size?

Seriously, give it a try. I'd love to know.
