New Trim Technique: Two Tails or Two Heads

Only published comments... May 29 2008, 05:04 PM by GregStaten

This post is the second in a series of articles about some of the smaller features and changes in version 3.0 of Media Composer and Symphony.

Here's a fairly common scenario.

 

ttt one

 

You are well into the edit and need to shorten clip B/2X in the above sequence. Unfortunately, the duration of the scene is already locked. What are your options? Well, you could use a dual roller trim at the edit point between B/2-X and B/1-A, but that would change the head frame edit on B/1-A, which is undesirable. Alternatively you could slide B/1-A, but that would change the head frame edit on BA/3-X, which is also undesirable.

 

Since neither single trim approach really works for you, you'll likely do an A-side trim on the tail of B/2-X, write the number of frames trimmed on a piece of paper, then find the tail of another shot in the scene that you could extend. It works, but hopefully you won't get distracted by a panicked producer while you're searching for that other clip.

 

In Media Composer version 3.0 we've provided a new trimming technique that not only solves this problem, but many other similar problems. Indeed, I may never do another slide trim again. You can now select two A-sides (tails) or two B-sides (heads) anywhere in the timeline and perform an asynchronous trim on those two edits!

 

In this scenario I'll select the tail of B/2-X and BA/3-X, as seen in the timeline below:

 

ttt two

 

Note the trim rollers. To make the above selection I lassoed the edit between B/2-X and B/1-A, switched to an A-side trim, Shift+clicked on the other two rollers. Once selected you can use any trim technique you desire (drag, J-K-L, on-the-fly, etc). After trimming the tail of B/2-X, the timeline looks like the following:

 

ttt three

 

Notice that the position of shot B/1-B (and everything afterward) has not changed. You made your adjustment in one interactive trim without changing the duration of the scene.

 

Give it a try when you get version 3.0. I think you'll like it!

Very cool.  But I'm a little confused on something.  Let's say you want to shorten the tail of clip B/2-X...how does it know that you want to lengthen the tail of BA/3-X, instead of also shortening it as well?  I assumed that if you use the < key or something to shorten the first clip, it would by default shorten the other clips that are also in trim mode...or does this method only allow for asynchronous trimming and not even allow both clips to be either shortened or lengthened? (sorry if I'm asking this is a confusing way)

Hi Sandman.

The way an asynchronous trim works is that the rollers always roll in opposite directions. If you drag one set to the right the other set moves to the left. This ensures that you get two 'in kind' trims which results in no change in total duration. Typically these trims have rollers in opposite directions (such as a slip trim), but this new trimming technique allows the rollers to be pointed in the same direction.

BTW, if you want to use J-K-L or an on-the-fly method of trimming, place the position indicator on the trim handle you want to control from. Then if you trim backwards with, for example, J+K, the other roller will trim forwards.

Big fan of avid style trimming - great new feature.

Is there any way of using keyboard shortcuts to move blue position indicator? Currently I have to deselect and reselect to move the 'watched' edit point.

Hey Greg, thanks for the info.  I'm actually familiar with asynchronous trimming, I guess I was just wondering about if you have two sets of clips in trim mode (like you have B2X and BA3X), if it's always going to be an asynchronous trim.  For example, is there a way to have those exact same edit points selected the way you do in your example, and not perform an asynchronous trim (ie. the tails of both clips get shorter without one having to go one way and one going the other?).  I don't know if that would be useful to do (probably just easier to do them one at a time), but I was just curious.

Ah. I understand your question now. No, two tails or two heads will always trim asynchronously. We talked about scenarios where we could select three, four, or more tails or heads and then trim synchronously but decided not to go there at this time.

Nice job, Greg. A couple comments: I sense that you are excited about this New Trim mode, but I'm not getting a big "before and after" feeling from the last two graphics, indeed the only thing I see changing is the position of the 01:00:15:00 in the TC1 track. Or maybe I'm going blind.  

I'm a  "never turn off synclocks" guy. I am very comfortable editing & trimming that way on my documentary/narration based multi-track timeline but I never do asymetrical trimming, because I find it easier to just lasso or shift select multiple segments over multiple tracks, rather than individually pecking around for double rollers to shift+click into single rollers. Once I have my multiple segments highlighted, I just nudge them earlier or later in the timeline to perfection, keeping the segments highlighted until I am happy. Then I use double-roll to repair any damage to other solid clips.

With your new trim mode, can we use the keyboard shortcut "Cycle Trim Sides" independently on both pairs of the two Trim rollers instead of resorting to the shift-click method to set up the trim?

Can the new trim mode be used with Synclocks all ON and if so, does using it break any underlying clips not involved in the trim?

If there is a way to do this it would be great: allow Segment mode to function on clips that are not involved in the new Trim. In other words, the trim rollers stay active with all the benefits of PlayLoop review and J-K-L as you described, but any non-trim segments are simultaneously available for highlighting and movement without removing Composer from Trim mode. This would be a huge time saver for me.

Thanks for making this new feature!

Hi there itmatters. Take another look at the timeline. Notice that while B/2-X (the first shot we see in the timeline) has shortened at its tail, BA/3-X (the third shot we see in the timeline) has lengthened at its tail.

This type of trim absolutely works with Sync Locks but Cycle Trim will not help you set this up as trimming two tails or heads is a special case. Unfortunately at this time you must Shift+Click the rollers to configure them.

Interesting idea about utilizing Segment mode and Trim together. Let me play with the idea. I may come back to you with some questions on your specific uses for this feature request.

Hi Greg, doh! I see it now, plain as day.

I'm looking forward to the new 3.0 software and totally applaud the effort to add more complex features into the timeline trim and segment tools. We doc editors need all the productivity enhancements Avid can offer.

Looking forward to this.  I needed it today, actually.
