On-the-fly trimming

From: Avid Media Composer 5 Essential Training

Video: On-the-fly trimming

Another very dynamic type of trimming is Trim on the Fly, which actually allows you to perform a trim while in play loop. In this way you're actually able to watch the transition play from pre-roll to post-roll and then make trim quite instinctually. That is when you think the shot should start or end, you can simply press a button and the trim is performed. Let's take a look at how it works. Now this shot here, we've agreed it'd be nice if we could be see the B roll while he heard Tony talk.

On-the-fly trimming

Another very dynamic type of trimming is Trim on the Fly, which actually allows you to perform a trim while in play loop. In this way you're actually able to watch the transition play from pre-roll to post-roll and then make trim quite instinctually. That is when you think the shot should start or end, you can simply press a button and the trim is performed. Let's take a look at how it works. Now this shot here, we've agreed it'd be nice if we could be see the B roll while he heard Tony talk.

Before, we just simply dragged our rollers over. Now let's practice this same exact trim using Trim on the Fly. I am going to get into Dual-Roller Trim because we want this transition to be moved over to the right, and I'm going to play loop. Again we have a four-second pre- roll and a four-second post-roll. At the point where I want my transition to be, I'm simply going to hit either I or O. For this it doesn't matter. You can press either one. So I'm going to play loop by pressing Spacebar.

(Music Playing.) (Male speaker: You have the mentor and the apprentice, Drossel?) (Music Playing.) Okay, I think I'm going to mark it right here. What I did there was I watched the transition through and where I wanted that transition to appear, I just pressed my O key and the transition updated immediately.

Let's go ahead and play loop and see how we like it. (Music Playing.) (Male speaker: You have the mentor and the apprentice, Drosselmeyer and Mini-Meyer.) (Male speaker: And that's one of the themes.) Okay, that worked pretty well. Let's go to our next edit by pressing Fast-Forward, and we'll do the same thing. The moment that I want my transition to move, I'm simply going to hit either the I or the O key and it will immediately update. Let's play loop.

(Male speaker: Is like you know the apprentice is trying to learn how to become a magician.) (Music playing) (Male speaker: Is like you know the apprentice is trying to learn? the story?) Right here I press the I key and the transition updated. Let's go ahead and play loop and see how we like it. (Male speaker: The story is like you know the apprentice is trying to learn how to become a magician.) (Music playing.) (Male speaker: The story is like...) I think that worked pretty well.

We've changed the transition points quite dynamically because I was actually able to play through the edit, press a button, and that edit immediately updated. Let's fast-forward just a bit. I'm going to play loop around this and we'll see if there is anything to repair about this edit. (Male speaker: You know he's becoming a bit of a master himself, so? (Male speaker 2: So it's almost like a thread that keeps all of the pieces?) Okay, looks like we have a couple of issues here on both the A side and the B side.

What I'm going to do is actually play loop, but I'm only going to play the A side. It's going to stop right at the transition. Let me go ahead and decrease my pre-roll and post-roll, and I'm going to press Q during the play loop so it only loops on the A side. (Male speaker: The master? the master himself? the master himself? so this?) So that helped a lot, I was able to really only hone in on the A side, we know we need to make an A side reductive trim, and so I'm just going to make sure that both my audio tracks are selected, get into A side trim, and the moment that I hear him finish his sentence, I'm going press the I or the O key and the shot is going to update, my trim is going to be done for me.

Go ahead and Play. (Male speaker: The master himself? so this?) So as soon as I heard him finish the word himself, I press the O key, the trim was performed and let's play loop. (Male speaker: Becoming a bit of a master himself? so this?) (Male speaker 2: So it's almost like a?) By the way, if I wanted to play only the B side I could do that by playing loop and then pressing W, let's try that. (Male speaker: ?a bit of a...) (Male speaker 2: So it's almost like a?) Okay, so we've isolated the B side, we know that we need to trim right before he said, "it's almost like a", so I'm going to zoom way in, and the moment I hear him say these extraneous words I'm going to hit the I or O key, the trim is going to be performed, and hopefully we'll get it right on.

Let's go ahead and play loop. (Male speaker: ...a bit of a master himself?) Okay, so the first thing I'm going to do is get into B side Single Roller Trim and the moment I hear him say his extraneous words, I'm going to hit the I or O key, the trim will be performed, and hopefully we get it tight enough. Let's try it out. (Male speaker: ...a bit of a master himself?) (Male speaker 2: So it's almost like a?) (Male speaker: ...a bit of a?) So I hit the O key and since trim was performed, let's see how it worked, I'm going to play loop just on the B side.

(Male speaker 2: So it's almost like a thread that? it's almost like a thread that?) I think that worked really well. I am going to zoom back out and clear my marks here. Let's go ahead and just play through this and make sure that everythingmakes sense. (Male speaker: ?himself?) (Male speaker 2: So it's almost like a thread that keeps all of the pieces?) Both gentlemen finished what they had to say or started what they had to say on time.

I'm just going to give Dr. Shannon a tiny bit more breathing room and I'll do that by getting into trim, and this time, I think I will just JKL, I'm going to hold down K, tap my J two or three times. And let's see if that was enough room. (Male speaker: ?a bit of a master himself?) (Male speaker 2: So it's almost like a?) Well unfortunately we introduced one more extraneous syllable. I'll go ahead and just take that out, probably one frame will do it and I'll go ahead and press W to play only on the B side.

(Male speaker 2: So it's almost like a?) Beautiful! Trim on the fly is a great tool, but probably not as often used as JKL trim or other types of dynamic trimming. However, trimming on the fly is really perfect for special cases, which you'll find that you need to do from time-to-time.
