WEBVTT 1 00:00:00.743 --> 00:00:01.958 In this tutorial, 2 00:00:01.958 --> 00:00:06.050 we're going to learn how to adjust the speed of a clip. 3 00:00:06.050 --> 00:00:07.560 There's multiple ways to do it, 4 00:00:07.560 --> 00:00:09.608 and I'll show you a couple of them. 5 00:00:09.608 --> 00:00:11.912 Here we have this time lapse, 6 00:00:11.912 --> 00:00:12.960 well not really a time lapse, 7 00:00:12.960 --> 00:00:17.935 but just a very long shot that I recorded in the Alps. 8 00:00:17.935 --> 00:00:19.591 It's three minutes, actually, 9 00:00:19.591 --> 00:00:20.424 so not that long, 10 00:00:20.424 --> 00:00:23.070 but if we speed it up to a few seconds, 11 00:00:23.070 --> 00:00:25.021 we'll be able to see the movement 12 00:00:25.021 --> 00:00:27.291 of these clouds even better. 13 00:00:27.291 --> 00:00:28.930 Right now if you sit through it, 14 00:00:28.930 --> 00:00:31.527 you can barely see any movement. 15 00:00:31.527 --> 00:00:33.455 So we wanna speed this up. 16 00:00:33.455 --> 00:00:35.584 One of the easiest ways to do that 17 00:00:35.584 --> 00:00:37.947 is just simply right clicking, 18 00:00:37.947 --> 00:00:40.859 going to speed slash duration, 19 00:00:40.859 --> 00:00:45.172 and this brings up this speed slash duration panel. 20 00:00:45.172 --> 00:00:48.587 Right now the speed is set to 100%, 21 00:00:48.587 --> 00:00:50.762 and you see the duration down here. 22 00:00:50.762 --> 00:00:54.179 We can increase this to, say, 2000%, 23 00:00:55.360 --> 00:00:57.247 and when you do that you see the duration 24 00:00:57.247 --> 00:00:59.012 down here change as well. 25 00:00:59.012 --> 00:01:00.888 Say you know specifically that you need 26 00:01:00.888 --> 00:01:04.580 this clip to be just three seconds, 27 00:01:04.580 --> 00:01:07.249 you can literally click and drag 28 00:01:07.249 --> 00:01:08.717 to the left or right down here, 29 00:01:08.717 --> 00:01:10.122 or you can go in, 30 00:01:10.122 --> 00:01:14.289 click it once, and type in the speed that you want. 31 00:01:15.312 --> 00:01:17.549 You'll also see here that you can reverse the speed 32 00:01:17.549 --> 00:01:20.050 if you wanna make something reverse. 33 00:01:20.050 --> 00:01:21.528 If there is audio, 34 00:01:21.528 --> 00:01:22.756 and there's someone talking, 35 00:01:22.756 --> 00:01:26.279 you can maintain audio pitch by checking this box. 36 00:01:26.279 --> 00:01:27.903 Otherwise if you speed something up, 37 00:01:27.903 --> 00:01:29.710 people's voices will get really high, 38 00:01:29.710 --> 00:01:31.391 or if you slow it down, 39 00:01:31.391 --> 00:01:33.890 people's voices will get very low. 40 00:01:33.890 --> 00:01:35.887 So this has a way of actually maintaining 41 00:01:35.887 --> 00:01:38.975 the pitch of a voice or of the audio, 42 00:01:38.975 --> 00:01:41.469 even with a speed adjustment. 43 00:01:41.469 --> 00:01:43.220 A long time ago it seems like now, 44 00:01:43.220 --> 00:01:45.121 we learned about ripple edits 45 00:01:45.121 --> 00:01:46.556 and shifting trailing clips. 46 00:01:46.556 --> 00:01:48.414 If you check this button, 47 00:01:48.414 --> 00:01:51.159 all of the clips to the right of this one 48 00:01:51.159 --> 00:01:53.740 will jump to the left. 49 00:01:53.740 --> 00:01:57.822 So right now I don't have any other clips of this timeline, 50 00:01:57.822 --> 00:01:59.657 but if I did have a bunch, 51 00:01:59.657 --> 00:02:02.628 and I did make this a lot shorter, 52 00:02:02.628 --> 00:02:05.430 by checking this box it will move all of these clips 53 00:02:05.430 --> 00:02:09.032 to the left after it makes this clip shorter. 54 00:02:09.032 --> 00:02:11.382 So I'm just going to leave those unchecked for now. 55 00:02:11.382 --> 00:02:13.674 Select okay, and you see what happens 56 00:02:13.674 --> 00:02:16.091 is our clip got really short. 57 00:02:16.936 --> 00:02:18.349 So let's go play through this. 58 00:02:18.349 --> 00:02:20.266 See what it looks like. 59 00:02:21.908 --> 00:02:25.506 And there's a little bit of a stutter, 60 00:02:25.506 --> 00:02:27.464 But it does a pretty good job. 61 00:02:27.464 --> 00:02:29.034 To remove that stutter 62 00:02:29.034 --> 00:02:32.908 and render out this effect or any effect. 63 00:02:32.908 --> 00:02:37.075 You can do that by going up to sequence render in to out. 64 00:02:39.652 --> 00:02:40.485 Once I do that, 65 00:02:40.485 --> 00:02:44.900 you'll notice that this yellow bar up here becomes green. 66 00:02:44.900 --> 00:02:47.512 A yellow bar means that your computer 67 00:02:47.512 --> 00:02:48.884 can probably play through it, 68 00:02:48.884 --> 00:02:51.615 but there is an effect applied to it, 69 00:02:51.615 --> 00:02:53.098 and it's not rendered out. 70 00:02:53.098 --> 00:02:56.107 A green bar means that there is an effect on there, 71 00:02:56.107 --> 00:02:57.532 but it has been rendered, 72 00:02:57.532 --> 00:02:59.973 and a red bar means that there's an effect on there 73 00:02:59.973 --> 00:03:03.274 that won't play because it needs to be rendered out. 74 00:03:03.274 --> 00:03:07.481 So if there's red bars after you add an effect, 75 00:03:07.481 --> 00:03:08.981 so let's just say, 76 00:03:11.276 --> 00:03:13.776 let's do this warp stabiliser, 77 00:03:14.718 --> 00:03:15.966 so if I type warp, 78 00:03:15.966 --> 00:03:18.412 which we'll learn about in a future lesson. 79 00:03:18.412 --> 00:03:21.496 If I add this, you'll see that it, 80 00:03:21.496 --> 00:03:25.065 not only it can't be used when I speed up a clip, 81 00:03:25.065 --> 00:03:28.718 but there's this red bar that needs to be rendered out. 82 00:03:28.718 --> 00:03:30.292 I'm gonna undo that. 83 00:03:30.292 --> 00:03:33.892 So that's how you speed up a clip or slow down a clip. 84 00:03:33.892 --> 00:03:35.615 I'm gonna undo that all, 85 00:03:35.615 --> 00:03:36.613 and I'll show you a different way 86 00:03:36.613 --> 00:03:38.328 that you could speed up clips. 87 00:03:38.328 --> 00:03:40.010 If you click on any clip, 88 00:03:40.010 --> 00:03:41.789 go up to effects controls, 89 00:03:41.789 --> 00:03:43.789 you see under motion and opacity, 90 00:03:43.789 --> 00:03:46.345 this time remapping option. 91 00:03:46.345 --> 00:03:49.967 This allows you to literally remap the time, 92 00:03:49.967 --> 00:03:51.774 speed up, slow down, 93 00:03:51.774 --> 00:03:54.288 even change from slow to fast. 94 00:03:54.288 --> 00:03:55.121 We'll learn about that in 95 00:03:55.121 --> 00:03:57.530 the next lesson with speed ramping, 96 00:03:57.530 --> 00:04:00.130 but if you drop down this button right here, 97 00:04:00.130 --> 00:04:04.297 you have this bar that you can decrease or increase, 98 00:04:05.388 --> 00:04:07.060 and by doing that, 99 00:04:07.060 --> 00:04:10.643 it speeds up or decreases the video itself. 100 00:04:12.775 --> 00:04:15.232 You will notice though there is a limit 101 00:04:15.232 --> 00:04:17.565 to 1000 with time remapping, 102 00:04:18.469 --> 00:04:20.346 and to get that three second clip, 103 00:04:20.346 --> 00:04:22.564 we had to the that right clip speed duration option 104 00:04:22.564 --> 00:04:26.206 so that we can go past 1000%. 105 00:04:26.206 --> 00:04:29.217 It was like 6000 or something like that. 106 00:04:29.217 --> 00:04:31.433 You'll also noticed now though that I have 107 00:04:31.433 --> 00:04:35.016 a 1000 speed adjustment via time remapping, 108 00:04:36.439 --> 00:04:38.819 but the clip speed duration, 109 00:04:38.819 --> 00:04:41.974 it thinks it's at 100%, 110 00:04:41.974 --> 00:04:43.631 even though it's still speeded up. 111 00:04:43.631 --> 00:04:46.640 So you can kind of use these two effects 112 00:04:46.640 --> 00:04:50.678 to increase the speed more than the limits. 113 00:04:50.678 --> 00:04:51.926 Okay? 114 00:04:51.926 --> 00:04:55.603 So those are the two ways that you can increase or decrease 115 00:04:55.603 --> 00:04:56.888 the speed of a clip. 116 00:04:56.888 --> 00:04:58.981 We're going to be looking at the time remapping 117 00:04:58.981 --> 00:05:02.597 in the next lesson to do some speed ramps 118 00:05:02.597 --> 00:05:06.764 where we speed and then slow down into some sort of action. 119 00:05:07.812 --> 00:05:08.711 Thanks for watching, 120 00:05:08.711 --> 00:05:10.133 and we'll see you in that lesson.
