WEBVTT 00:00.860 --> 00:07.970 Welcome to the time line in this video you'll be introduced to the timeline shown how to adjust the 00:07.990 --> 00:15.170 playback and rendering range and how to alter the frames per second of your animation. 00:15.200 --> 00:17.750 So let's hop straight on over into blender. 00:18.820 --> 00:25.770 Okay so let's first of all make the timeline appear and I hid it a few lectures back. 00:25.810 --> 00:28.080 Now you may already still have it on your screen. 00:28.090 --> 00:30.470 I don't want to reveal it that way. 00:30.470 --> 00:31.590 So let's get rid of that. 00:31.620 --> 00:37.930 I'm going to create a new window and I'm going to change this bottom one to the timeline view and I'm 00:37.930 --> 00:43.950 just going to push all this lot over here to one side so we can see the entire head a bar of the time 00:43.950 --> 00:46.620 line along the bottom of the screen here. 00:46.630 --> 00:48.700 Now I'm just going to go through it bit by bit. 00:48.700 --> 00:53.700 Obviously here we have what the window we have is in and we've got it selects to the time line just 00:53.740 --> 00:58.170 here at the bottom then it's got a picture of a little clock under view. 00:58.180 --> 01:01.890 Well we're not going to go into anything under view for the moment and the markers. 01:01.890 --> 01:05.610 Now this is incredibly useful if you need to mark a point in time. 01:05.670 --> 01:10.310 Now when you initially add a marker it's named it f underscores 0 1. 01:10.480 --> 01:16.720 You can right click and move that to where you want and press left click to place it just like you do 01:16.750 --> 01:18.030 objects. 01:18.310 --> 01:24.100 You can zoom in an out of the time line by the way just nudge the scroll will vary with the scroll Well 01:24.160 --> 01:25.810 if necessary. 01:25.810 --> 01:33.770 Now if f underscores 0 1 is not to your liking under a marker We've also got the option to rename marker. 01:34.030 --> 01:39.480 You can see there's a key here for M to add a marker and rename marker is control an M. 01:39.530 --> 01:44.740 The moment we have that for instance if we were going to make our model jump at this point we can put 01:44.740 --> 01:46.960 in a marker there that we wanted to be name. 01:46.960 --> 01:47.800 Jump. 01:47.800 --> 01:49.620 Perfect frame. 01:49.630 --> 01:52.510 Now there are some or awesome options here. 01:52.570 --> 01:54.560 The start frame and end frame. 01:54.640 --> 01:56.300 So the short cuts here. 01:56.350 --> 01:57.230 S n e. 01:57.340 --> 02:02.800 Well they're the same as this starts frame and end frames here so I'll probably be editing them down 02:02.800 --> 02:05.230 here rahaf and going into the menu. 02:05.230 --> 02:11.110 However if you've just gone to a certain location on a bigger project say frame 80 is where you need 02:11.110 --> 02:12.820 to start from and work on. 02:12.820 --> 02:18.760 You can set the staff home very quickly by just doing that out rather than waiting around and going 02:18.760 --> 02:18.940 here. 02:18.950 --> 02:23.730 But since in this case we're going to be starting from zero and going onwards from there. 02:23.740 --> 02:27.530 Those options aren't necessary in this module. 02:27.710 --> 02:34.280 And now if we want to just preview a range now this is very helpful so we go to set preview range. 02:34.360 --> 02:40.630 We can quickly select this area here by drawing a box around it essentially and it limits the playback 02:40.630 --> 02:45.480 range which is here to this section here now. 02:45.670 --> 02:50.920 The great thing about that is it doesn't change anything else so we go back to frame when we clear the 02:50.920 --> 02:53.820 preview range goes back to how it was before. 02:54.340 --> 02:59.410 So we have the start and end frame here which you can see as zero on this side and goes all the way 02:59.410 --> 02:59.830 along. 02:59.830 --> 03:04.960 I'm just clicking and dragging the green thing to demonstrate to 250 and obviously we can increase that 03:04.990 --> 03:06.920 and decrease that as we like. 03:07.090 --> 03:12.180 And then we've got some playback buttons along here so we got all the way back to the beginning. 03:12.280 --> 03:15.730 Rewind play backwards play forwards. 03:15.730 --> 03:18.950 Fast forward and all the way to the end frame. 03:19.240 --> 03:24.640 So how do we control the frames per second and how do we know what they are. 03:24.640 --> 03:27.010 I don't see any option along here. 03:27.130 --> 03:30.520 The rest of this we won't deal with on the head bar by the way will come to that. 03:30.640 --> 03:34.210 This area here with the what looks like a record button. 03:34.210 --> 03:38.670 This Red Circle where we talk about key frames in the next lecture. 03:38.800 --> 03:44.170 So in order to change the frames per second well that's hidden under the render properties. 03:44.170 --> 03:46.580 I'm just going to move this back out now. 03:46.740 --> 03:49.370 So we've got the camera here were in the Properties window. 03:49.450 --> 03:51.400 The little picture of the Canda the render properties. 03:51.400 --> 03:58.060 Now scrolling down or scrolling up in this case you want the one that says dimensions and down here 03:58.060 --> 04:02.890 we have one of the options is frame rates and that's where you can set the frame rate so if we set this 04:02.890 --> 04:08.830 back to zero and press play it's currently moving along at 24 frames per second. 04:08.950 --> 04:18.010 So by the time we reach 240 frames 10 seconds of animation has passed before it automatically loops 04:18.070 --> 04:20.800 and plays through the animation again. 04:20.800 --> 04:21.630 Excellent. 04:21.670 --> 04:24.930 So if we change that to 60 frames per second. 04:25.060 --> 04:28.800 The animation speed is going to be a lot lot faster. 04:28.930 --> 04:35.740 Now in this case what we probably want to do is leave it how it is we're not matching it up to any existing 04:35.740 --> 04:36.450 video. 04:36.490 --> 04:40.710 So I'm quite happy leaving it at 24 frames per second. 04:40.960 --> 04:48.040 At any point you can pause a video and we can play it backwards and you can pause a video and play it 04:48.040 --> 04:48.820 forwards. 04:48.870 --> 04:53.400 You notice as I was hovering over that it gives us a short koshy's Alton A. 04:53.560 --> 04:59.200 So on the keyboard at any point you can hear Oulton a and it will start playing back the animation that 04:59.200 --> 05:00.230 we're working on. 05:03.590 --> 05:07.760 I'm so used to hitting space it's not space it's OT now shift. 05:07.780 --> 05:13.440 Alright then I will play it backwards shift Olsen a will play our animation backwards. 05:14.280 --> 05:21.890 And Altern a will stop it and play it forwards and stop it and play it forwards and then we can go backwards 05:21.890 --> 05:23.650 and forwards as much as we like. 05:25.780 --> 05:31.640 Looking at the animation we've made or we can just click the pause button down there. 05:31.690 --> 05:32.750 Great. 05:32.770 --> 05:34.970 One final consideration to make. 05:35.110 --> 05:40.090 When you work at a higher frame rates I f p s here are at 60. 05:40.120 --> 05:47.170 There's going to be a lot more work for your computer to do when rendering in order to get your animation 05:47.200 --> 05:49.170 out because it's going to have to. 05:49.170 --> 05:53.480 In this case do one point something that worked over twice the amount of work. 05:54.200 --> 05:56.980 In this case is going to have to do over twice the amount of work. 05:57.080 --> 06:01.740 If we set it to 20 to 60 frames per second. 06:01.850 --> 06:07.370 And one thing you do not want to do is keep hopping between frames per second because it will change 06:07.370 --> 06:08.900 how your animation looks. 06:08.900 --> 06:15.560 If you set up your animation when it's at 60 frames per second and you slow it essentially slow it down 06:15.790 --> 06:20.240 24 frames per second your animation will get a lot slower. 06:20.240 --> 06:23.270 In fact it will be over half as slow. 06:23.270 --> 06:29.120 Now if you go the other way of we've said it 24 friends and we do our animation and then we go back 06:29.120 --> 06:33.080 in an adjusted 60 frames per second it will go over twice the speed. 06:33.350 --> 06:39.470 And so when you need to set this right at the very beginning you cant realistically go back and change 06:39.470 --> 06:40.350 everything. 06:40.400 --> 06:43.790 So make sure you get that right from the very beginning. 06:44.090 --> 06:44.810 Okay guys. 06:44.810 --> 06:45.930 Its challenge time. 06:45.950 --> 06:50.350 I'd like you to set the animation time to five seconds. 06:50.360 --> 06:57.710 So leaving the frames per second the frame rate at 24 frames per second set the start and end frame 06:57.980 --> 07:04.330 so that we will have a five second animation balls of video now and give that a go. 07:06.710 --> 07:07.760 Welcome back. 07:07.760 --> 07:12.230 Let's hop straight on over into blender and solve this little mathematical problem. 07:13.840 --> 07:14.260 Okay. 07:14.350 --> 07:16.510 So back over in blender. 07:16.510 --> 07:22.300 Let's just make make sure here the frame rate is 24 frames per second which it is brilliant. 07:22.300 --> 07:30.940 Now a five second thing will be five times twenty four or ten second one will be 240. 07:30.940 --> 07:34.960 So a five second one will be 120. 07:34.960 --> 07:41.560 So now we've got it on 120 you can see here we can see the changes in value here to 120 or indeed go 07:41.560 --> 07:45.200 to frame and set the end frame here or press E. 07:47.020 --> 07:47.980 And there we go. 07:47.980 --> 07:58.990 We'll now have ourselves a five second animation and if we count zero one two three four five. 07:59.050 --> 08:00.070 Perfect. 08:00.070 --> 08:02.790 Now of course you cannot set what ever one you like. 08:02.800 --> 08:08.170 But for the purposes of this exercise to keep it as short as possible so we can see our results as quickly 08:08.170 --> 08:09.020 as possible. 08:09.070 --> 08:16.140 If you set it at a five minute animation the render time is going to be astronomical compared to a shorter 08:16.140 --> 08:17.320 animation. 08:17.320 --> 08:22.910 So we'll be also working with our animation shortly and constraining it to those five seconds. 08:23.200 --> 08:23.740 Excellent. 08:23.740 --> 08:28.010 So we've got the timeframe set in the next lecture. 08:28.120 --> 08:32.470 We're going to be starting to animate our lamp bringing it to life. 08:32.470 --> 08:33.510 I can't wait. 08:33.520 --> 08:34.370 See you soon.
