Hi, folks.

I've been away from Avid for awhile, and I've hit the strangest snag.

In trim mode, little brackets appear on the far side of the two clips involved in the trim. This turns out to indicate that nothing beyond the brackets will be affected. Great, I'm sure that'll be a useful feature at some point, but I want to ripple the whole timeline. How do I turn this off?

Searching online has led me to try locking the track, but the trim mode won't select the transition in this case. I've also seen suggestions around the "features" section of the trim user prefs; this didn't help either. 

Any suggestions?

The white ghost brackets indicate the media available to be trimmed. 

A double roller trim won't affect the sync either side of the trim. 

No, it's not a media extent visual.

The brackets that I'm seeing are located at precisely the prior and next edits. If I use a single, left roller trim, it appears red and rather than push out the next shot as I trim to the right, it gobbles up the next shot until gone as if it were a double roller. Whereupon the bracket establishes itself at the new next edit and will allow me to gobble that one, too. Clearly, I had more media than the extent of that first clip.

Can you post a screen shot? From the description it sounds like you don't have enough media to trim, but you say that's not it, so it might help to be able to see what you're seeing.

What happens if you use a single yellow roller trim?

A red overwrite trim should eat up the shot so as to retain sync. material is removed and fille rput in its place.

Trying to drag that righthand red roller left will bong and show a red bracket when its at the limit of media. It will do the same when dragged right whan it hits the limit of that media.

I'm seeing what you describe when I end complete clips into the timeline with no handles of media to trim.

How does one alter the color of the roller? I only remember pink from the old dayz.

Hitting "P" to give me a single-side left roller gives me a red one.

There is media far in excess of the timeline segment available to the clip in question.

If the smart tool is enabled then the tool changes colour based on the mouses vertical position on that track. 

But you have to ensure the trim smart tool has yellow mode enabled. The smart trim tool can be off, in red mode, in yelliw mode or both. Alt clicking the smart trim tool at the top left of the timeline command strip changes the mode. 

Thank you. My problem is now solved.

Believe it or not, my Avid training was all the way back in 2008, prior to the introduction of the smart tools. I've used it only lightly since.

The tool did not display on my system, and after doing a google image search to see what the darn thing looked like (twice, since the initial images were pre-2019), I confirmed that it wasn't showing up. 

Then I went back into prefs again to see how to enable/display it; found nothing. 

Finally, the Avid knowledge base gave up the answer: I needed to create a new user profile, which is mandatory if your old one was pre-2019. Several parts of the GUI won't display without this, including the smart tools. 

"Never reuse old; always create new," right?
