Video: Combining trim tools

So far then, we have done everything using the Ripple Trim button. What happens when we start to use the Overwrite Trim button? Well, let's toggle Ripple Trim off and toggle Overwrite Trim on. Let's look at this little transition moment here in the sequence. (Female speaker: When I was just in elementary school. There's this weird--) Now let's say we wanted to try to pause there after 'elementary school' and a bit of a fade-down in the sequence, and then come back into interview clip 3 after a pause.

Combining trim tools

So far then, we have done everything using the Ripple Trim button. What happens when we start to use the Overwrite Trim button? Well, let's toggle Ripple Trim off and toggle Overwrite Trim on. Let's look at this little transition moment here in the sequence. (Female speaker: When I was just in elementary school. There's this weird--) Now let's say we wanted to try to pause there after 'elementary school' and a bit of a fade-down in the sequence, and then come back into interview clip 3 after a pause.

Then in that case what I could do is I could click down on the left-hand side of my transition-- notice I can also bring up the dual rollers in this mode too--but click on the left-hand side of my transition point, like so. Now when I click down and drag back, notice that I'm actually adding black into the sequence instead. I am overwriting black into the sequence. In fact, I have removed frames from the outgoing side now, but I have managed to open up a black gap in my sequence.

So, in actual fact, I probably now need to use Overwrite Trim and Ripple Trim in concert with each other. So what I am going to do is I am actually going to toggle over to Ripple Trim, and now I'm going to push these back the other way, so I get back to the end of my statement there. Let's play that back and see how it looks. (Female speaker: I was just in elementary school.) Didn't quite get all the way, so let's just pull it a little bit further, school. There we go. Now incidentally, since I can't hear what's going here, it might be tricky just dragging around in the timeline like that.

If we wanted to hear our way to the end of the phrase 'elementary school', I could now hold down K on the keyboard and use L to scrub forward slowly and listen to the end of the word. (clip playing) Great! Now let's use spacebar for playback. (Female speaker: I was just in elementary school. There's--) So that's pretty good. We managed to open up a gap in our sequence using the red Overwrite Trim tool, and then we were able to preserve that gap and trim the end of our phrase back out to a natural ending using the Ripple tool.

So that's one way to start to use combinations of the Overwrite Trim and the Ripple Trim tools together in the timeline. But of course, another way to do that will be just switch on both tools simultaneously. Let's zoom in a little bit now, so we can see a little bit more of what's going on. Now, when I hover my cursor near the transition point at the top of the clip, I get the Overwrite Trim tool, and when I hover the cursor at the bottom of the clip area near the transition point, I get the Ripple Trim tool.

So this is how to effectively switch backwards and forwards between the different trim types using the Smart tools directly in the timeline. The beauty of using these two trim tools together is that they can be used to create some pretty complex trims very quickly indeed. For example, here in the Bin, I have a sequence called trim_challenge. First, let's just inspect what's going on here, starting at the earliest transition point where the sync issues begin. Remember, these white lines are what represent a sync problem in the sequence.

(Female speaker: and your partner.) So the first thing I am going to do then, since there is obviously something wildly out of sync here, is I am going to use the T key to mark the direction of my audio clip, and I can see up here that the duration of that segment is 18 seconds and 24 frames. So now let's do the opposite. Let's use the T key to mark the video section. Ah! It is also 18 seconds and 24 frames long. That gives me a clue that maybe these have literally just been knocked out of sync with each other.

If that's the case, then maybe all I need to do is line up the head of the audio with the head of the video and the sync issue should go away. To do this, I am going to remove the marks in my sequence first. I'm going to swap tracks so that I'm going to be trimming on the audio tracks only. Switch that off because otherwise it will autoselect my video track. So now what I am going to do is I am going to single-click on this side of the trim and I am actually going to add both tracks to that, and now I'm going to use the yellow trim mode to remove the black from the sequence there at that moment.

Now let's play back. (Female speaker: dance floor and your partner. My great-grandmother owned a clo--) Okay, so the trim point isn't exactly perfect at this moment, but we have now fixed the sync on interview clip 2. So the next thing I'd do if I was trying to repair a sequence is move down here to the next transition point and see what that's all about. (Female speaker:--was just in elementary school. There's this weird line that you have to try to ride.) Okay. Same thing again this time. What's going on here? We have got an audio duration of 26 seconds and seven frames.

Let's swipe back over there. This time the video is shorter than the audio, so this may mean that I need to add to the video segment to restore sync between video and audio. If I zoom in a little bit more, you can see that I have got these numbers here, and they actually tell me how many frames out of sync the audio is, compared to the video. So what I am going to do is I am going to try the same technique as I used last time there. I am going to try just extending the head of interview clip 3 video backwards in the timeline, back to where the audio begins.

Now this number has reduced. That tells me that the sync problem is getting better, but it's not completely solved. So maybe one way to fix this would be to remove some material from the incoming audio clip. So let's select that, let's click down with the yellow arrow, and let's remove some frames until we get in line with the video there. Now we are only 12 frames out of sync, so let's now use the yellow Ripple Trim function to trim an extra 12 frames back onto the head of our audio here.

So if we are starting at 53, 12 off of that would be 41, so let's trim to 41, and now we've removed the sync problem from interview clip 3. I could lasso and do a double-roller trim back to the head now, and we are starting to really fix up our sequence, like so. If you're using the course materials then I have an extra hard challenge for you here called trim_challenge the sequel. Load that up and practice using the Overwrite Trim and Ripple Trim tools to fix this sequence, put everything back into sync, and sew pull all the transition points nicely.

So you can really see the power of being able to trim directly in the timeline using the feedback from the interface and alternating between these two tools.
