I'm working on a "highlight" reel and I must be missing something.

When I produce (render) a video that is 3-10 minutes long, PD 12 wants to render a couple hours, or whatever is the length of the longest track in my timeline view. But I'm disabling those longer tracks, just leaving one short track on track 1.

The Produce time is dramatically extended, showing a length that matches the longest track. Takes much longer than it should and the file is much larger than it should be... (blank space after the highlights). If I delete the disabled tracks, it works as expected. Quick render, smaller file size.

Shouldn't I just be able to disable the tracks?

DETAILS:
I have couple longer videos (2 hours for one, and two 60 minute cuts) and I place those in tracks 2, 3 & 4.

I split the longer ones, copying out 10 to 60 second "highlights" and place those all back to back on track 1. I like leaving the original videos below in case I decide to add or modify the highlights track.

When done finding my highlights, I turn off both audio and video on all tracks below track one (the check box all the way to the left of the video).

When I go to produce and press start, it's clear it's rendering a long video at the length of the longest disabled track, rather than just the only enabled track.

In order to get it to the length of the cuts on track one, I have to remove the long videos from the timeline. Shouldn't PD 12 ignore all disabled tracks when it produces the finished movie?

All ideas welcomed.
