WEBVTT 00:00:07.050 --> 00:00:08.348 Hello. 00:00:10.210 --> 00:00:12.350 (Laughter) 00:00:12.710 --> 00:00:16.101 So - if I had a really had a heart attack... 00:00:16.329 --> 00:00:20.750 how many of you are confident that you would know what to do 00:00:20.750 --> 00:00:22.853 to save my life? 00:00:22.907 --> 00:00:25.143 Put your hands up if you are. 00:00:25.989 --> 00:00:30.710 Okay, so some, some - but many of you are not confident at all. 00:00:30.710 --> 00:00:34.370 And to be honest, you're right to be worried. 00:00:34.370 --> 00:00:38.970 Because today, about 1000 people will die in Europe alone 00:00:38.970 --> 00:00:41.543 from cardiac arrest and choking. 00:00:41.543 --> 00:00:44.116 And about the same number in the United States. 00:00:44.116 --> 00:00:46.690 And many more, all around the world. 00:00:46.870 --> 00:00:50.270 Now many of those victims could be saved 00:00:50.290 --> 00:00:54.490 if the people around them knew simple emergency skills. 00:00:55.499 --> 00:00:57.702 Now wouldn't it be great 00:00:57.727 --> 00:01:01.691 if we had a better way to teach those emergency skills? 00:01:01.691 --> 00:01:04.599 Maybe we could use the internet to do it. 00:01:05.041 --> 00:01:08.077 Maybe we could do something like this... 00:01:08.777 --> 00:01:12.370 (Video) Narrator: Lifesaver is an experiment in a whole new way 00:01:12.370 --> 00:01:14.060 to teach emergency skills. 00:01:16.660 --> 00:01:20.289 It's a movie you play like a game. 00:01:20.490 --> 00:01:24.610 It throws you into three situations where someone will be dead in 10 minutes 00:01:24.610 --> 00:01:27.616 unless you do the right thing. 00:01:28.640 --> 00:01:30.130 You learn by doing. 00:01:30.392 --> 00:01:33.234 Do it wrong - and see the consequences. 00:01:42.758 --> 00:01:44.788 Man: Call for an ambulance! Woman: Okay! 00:01:44.788 --> 00:01:48.842 Narrator: Do it right - and sense the thrill of saving a life. 00:01:49.410 --> 00:01:51.130 Woman 1: Isn't that the ambulance? 00:01:51.130 --> 00:01:54.470 Shouldn't we just wait for the ambulance people to arrive? 00:02:00.099 --> 00:02:03.739 Woman 2: No, no, he can't wait. Machine voice: Shock delivered. 00:02:03.739 --> 00:02:07.036 Woman 1: Jake, come on wake up! Wake up! 00:02:07.036 --> 00:02:09.033 Man: Did it work? Did it work? 00:02:09.033 --> 00:02:11.680 Woman 2: Guys please! Machine voice: Start CPR. 00:02:11.680 --> 00:02:14.737 Woman 1: Do something! Woman 2: I'm going to start CPR again. 00:02:15.240 --> 00:02:17.449 Woman 1: What do we do? 00:02:17.449 --> 00:02:20.033 Martin Percy: "Do something!" "What we do?" 00:02:20.033 --> 00:02:22.040 Words like that are being said 00:02:22.040 --> 00:02:25.140 hundreds of times, all around the world, today. 00:02:25.720 --> 00:02:28.237 So, what might be wrong with the current way 00:02:28.237 --> 00:02:30.754 of teaching people how to do CPR? 00:02:30.754 --> 00:02:33.273 I found out way back in 2004. 00:02:33.866 --> 00:02:36.927 Now this is not a picture of me - ok? 00:02:36.927 --> 00:02:39.988 But it was this kind of course. 00:02:39.988 --> 00:02:41.731 Little plastic dummy. 00:02:41.731 --> 00:02:44.148 One teacher for about ten people. 00:02:44.148 --> 00:02:45.542 Tea and biscuits. 00:02:45.542 --> 00:02:47.656 All very nice and relaxed. 00:02:47.656 --> 00:02:50.010 Now after the course, I got talking to the teacher 00:02:50.010 --> 00:02:51.460 who was an ambulance guy. 00:02:51.460 --> 00:02:54.990 And he said that this form of teaching has got some fundamental problems. 00:02:54.990 --> 00:02:59.160 It's small scale. One teacher - ten people. 00:02:59.160 --> 00:03:02.540 So it's always going to be very difficult to get to a situation 00:03:02.540 --> 00:03:05.970 where hundreds of thousands or millions of people know this stuff. 00:03:05.970 --> 00:03:08.420 It's expensive - because it's small scale. 00:03:08.420 --> 00:03:10.380 And it's inconvenient. 00:03:10.380 --> 00:03:13.994 Very often people who want to do one of these courses can't find a course. 00:03:13.994 --> 00:03:16.354 It's forgettable. 00:03:16.354 --> 00:03:18.762 People generally find that they forget 00:03:18.762 --> 00:03:20.912 what they've learned on one of these courses 00:03:20.912 --> 00:03:22.389 after about 6 months. 00:03:22.389 --> 00:03:24.116 They don't forget completely. 00:03:24.116 --> 00:03:25.808 But they forget to the extent 00:03:25.808 --> 00:03:30.270 that if a crisis really happens, they don't actually step forward and help. 00:03:30.270 --> 00:03:32.170 Because they don't have the confidence. 00:03:32.170 --> 00:03:35.530 But then the final problem was in a sense the most challenging. 00:03:35.530 --> 00:03:37.510 It's unrealistic. 00:03:37.552 --> 00:03:40.430 What the ambulance guy said 00:03:40.430 --> 00:03:44.570 is that if you are trying to save a friend of yours or a family member 00:03:44.570 --> 00:03:46.840 who's having a heart attack or choking 00:03:46.840 --> 00:03:52.250 it will quite possibly be the most terrifying moment of your life. 00:03:52.250 --> 00:03:54.579 There will be screaming. There will be shouting. 00:03:54.579 --> 00:03:56.589 There will be blood. There will be panic. 00:03:56.589 --> 00:03:59.489 It will not be at all nice or polite. 00:03:59.489 --> 00:04:02.859 And this form of training just doesn't prepare you for that. 00:04:02.859 --> 00:04:07.670 All of this leads to something called the bystander effect. 00:04:07.967 --> 00:04:10.619 And that comes in two horrible flavors. 00:04:10.619 --> 00:04:12.770 There's the untrained bystander. 00:04:12.770 --> 00:04:15.889 So those are people who've never done a CPR course. 00:04:15.889 --> 00:04:18.370 They have no idea how to save someone who's choking. 00:04:18.370 --> 00:04:21.509 If there's a crisis, they just have no idea what to do. 00:04:21.509 --> 00:04:24.009 And so of course they can't help. 00:04:24.009 --> 00:04:25.593 Now that's bad enough. 00:04:25.593 --> 00:04:28.668 But what's worse is the trained bystanders. 00:04:28.668 --> 00:04:32.436 So those people who have done a course - and this happens all the time - 00:04:32.436 --> 00:04:34.242 they have done a course. 00:04:34.242 --> 00:04:38.360 But when they see a real crisis, they're just completely frozen. 00:04:38.535 --> 00:04:40.882 Because it's so different 00:04:40.882 --> 00:04:44.206 from what they've seen before that they just can't help. 00:04:44.206 --> 00:04:45.921 And so they don't do anything. 00:04:45.921 --> 00:04:48.652 And so people die as a result. 00:04:49.240 --> 00:04:53.210 So - this is clearly something which could use a better idea. 00:04:54.200 --> 00:04:58.700 So I thought - why don't we take video and put it together with interactivity. 00:04:58.700 --> 00:05:00.590 We can make it realistic. 00:05:00.590 --> 00:05:03.200 So the videos will be very gritty, 00:05:03.200 --> 00:05:06.370 lots of screaming, lots of shouting, lots of panic. 00:05:06.590 --> 00:05:08.110 It'll be interactive. 00:05:08.110 --> 00:05:11.909 So you can't just sit back and watch the video and let it flow over you. 00:05:11.909 --> 00:05:15.652 You'll have to do things all the way through to make things happen. 00:05:16.149 --> 00:05:20.070 It will be a complement to existing training. 00:05:20.947 --> 00:05:22.800 No-one on the Lifesaver project 00:05:22.800 --> 00:05:26.840 thinks that you should not do a traditional training course. 00:05:27.698 --> 00:05:30.690 If you can get on a traditional course - terrific! Do it! 00:05:30.690 --> 00:05:33.039 But if you've done a course 00:05:33.039 --> 00:05:35.830 and you've kind of forgotten and you want a refresher 00:05:35.830 --> 00:05:38.380 or if you can't get on one of the traditional courses 00:05:38.380 --> 00:05:41.719 or if you just want more realism - then there will be this for you. 00:05:41.719 --> 00:05:45.150 It'll be convenient - because it'll be online the whole time. 00:05:45.150 --> 00:05:47.532 And we'll make it free. 00:05:48.061 --> 00:05:51.223 But of course that means we need to get funding. 00:05:51.223 --> 00:05:53.638 So, this is 2004. 00:05:53.638 --> 00:05:58.250 I thought, you know - an interactive film to save people's lives. 00:05:58.467 --> 00:06:01.459 Who is not going to want to fund that - right?! 00:06:01.459 --> 00:06:04.279 (Laughter) Okay so - cut to 2011. 00:06:04.279 --> 00:06:08.760 After seven years, I'd managed to raise half the money. 00:06:10.424 --> 00:06:12.136 By that stage 00:06:12.136 --> 00:06:15.950 I was working with a company called UNIT9 and we had managed to get 50% 00:06:15.950 --> 00:06:18.960 of the funding we needed from a UK government agency called 00:06:18.960 --> 00:06:21.171 the Technology Strategy Board. 00:06:21.171 --> 00:06:23.534 So we needed to find the other 50%. 00:06:23.534 --> 00:06:26.518 But we had twelve months so we weren't worried. 00:06:26.518 --> 00:06:29.730 We went to the biggest first aid charity in the UK 00:06:29.730 --> 00:06:32.060 and had some great meetings with them. 00:06:32.060 --> 00:06:34.390 And they came back with their feedback which was 00:06:34.390 --> 00:06:36.457 - no. 00:06:36.770 --> 00:06:39.023 But we still had eight months by that stage. 00:06:39.023 --> 00:06:40.656 So we still weren't worried. 00:06:40.656 --> 00:06:43.530 We went to a big UK medical charity. 00:06:43.530 --> 00:06:45.130 Had some great meetings again. 00:06:45.130 --> 00:06:48.308 And they came back with their feedback, which was - no. 00:06:48.530 --> 00:06:50.903 So by this stage we started to panic. 00:06:51.250 --> 00:06:53.940 And we went to everyone we could think of. 00:06:53.940 --> 00:06:57.830 We went to tiny charities like the Resuscitation Council UK. 00:06:57.830 --> 00:07:00.420 And they came back with their feedback which was 00:07:00.420 --> 00:07:01.502 - Yes. 00:07:02.215 --> 00:07:06.369 So Dr Jasmeet Soar, Dr Andy Lockey and Sarah Mitchell 00:07:07.727 --> 00:07:10.940 were the three decision makers at the Resuscitation Council UK 00:07:10.940 --> 00:07:14.230 who finally decided to give us the rest of the money we needed 00:07:14.230 --> 00:07:16.769 two days before the deadline. 00:07:16.769 --> 00:07:20.239 If they hadn't said yes Lifesaver would never have happened. 00:07:20.239 --> 00:07:21.909 It was that close. 00:07:21.909 --> 00:07:24.233 Okay so Lifesaver was completed. 00:07:24.233 --> 00:07:25.834 It's three films. 00:07:25.834 --> 00:07:29.360 In two of the films, you save someone who's had a heart attack. 00:07:29.360 --> 00:07:32.533 In one of the films, you save someone who's choking. 00:07:32.533 --> 00:07:35.354 And we throw you right in at the deep end. 00:07:35.354 --> 00:07:38.900 So let's look at the first choice that you come across in the first film. 00:07:38.900 --> 00:07:42.004 (Video) Woman 1: I don't think he's mucking around. Jake, come on. 00:07:42.004 --> 00:07:45.750 Jake come on, open your eyes. Come on. 00:07:45.750 --> 00:07:49.083 Man: Should we call someone? Woman: I don't - I don't know. 00:07:49.083 --> 00:07:51.305 Can you hear me? Open your eyes! 00:07:51.305 --> 00:07:53.527 Why does he keep doing that with his mouth? 00:07:53.527 --> 00:07:55.749 Narrator: Let's say this is you. 00:07:55.749 --> 00:07:59.439 You're not a first aid expert. What do you do now? 00:08:00.596 --> 00:08:03.449 MP: So here we have the bystander choice. 00:08:03.449 --> 00:08:06.810 So you have to positively get involved. Now this choice. 00:08:06.810 --> 00:08:08.989 We're in a pedestrian environment. 00:08:08.989 --> 00:08:10.416 There's no cars. 00:08:10.416 --> 00:08:12.773 Do we do the health and safety thing? 00:08:12.773 --> 00:08:15.480 Check for any risks? Or do you just go and save the guy? 00:08:15.480 --> 00:08:17.969 So - check for danger? Hands up. 00:08:17.976 --> 00:08:21.058 Run to him now? Hands up. 00:08:21.058 --> 00:08:23.489 Thank you madam. Let's try run to him now. 00:08:23.489 --> 00:08:25.946 Oh, and we get hit by a bicycle. (Laughter) 00:08:25.946 --> 00:08:28.403 So that happens very often 00:08:28.403 --> 00:08:30.860 if you're ever in that situation, madam. It's fine. 00:08:30.860 --> 00:08:33.333 She's enthusiastic, that's the important thing. 00:08:33.333 --> 00:08:35.806 If you're ever in that situation. 00:08:35.806 --> 00:08:39.046 Very often, people get injured because they're so anxious to help. 00:08:39.046 --> 00:08:41.049 Lifesaver is available in three versions. 00:08:41.049 --> 00:08:42.574 There's one for computer. 00:08:42.574 --> 00:08:45.515 And two for tablet and smartphone. 00:08:45.515 --> 00:08:47.299 For tablet and smartphone 00:08:47.299 --> 00:08:49.859 you move your device up and down two times a second. 00:08:49.859 --> 00:08:53.189 If you're on iPhone this is what you're seeing. 00:08:53.189 --> 00:08:55.439 So you're getting very accurate feedback 00:08:55.439 --> 00:08:58.532 on are you really doing it at the right speed. 00:08:58.532 --> 00:09:01.933 So it's a nice tactile way of learning CPR. 00:09:02.958 --> 00:09:06.660 So, guidelines for doing good talks tend to say 00:09:06.660 --> 00:09:09.563 no more than about two words per slide. 00:09:09.563 --> 00:09:12.466 Lifesaver's been out for more than a year. 00:09:12.466 --> 00:09:14.118 How's it done? 00:09:14.118 --> 00:09:16.912 So this is the worst slide you're going to see all evening. 00:09:16.912 --> 00:09:18.940 These are the prizes that it's picked up. 00:09:18.940 --> 00:09:21.370 It won a Webby. It was nominated for a BAFTA. 00:09:21.370 --> 00:09:23.420 It won 4 golds in the UK e-learning awards. 00:09:23.420 --> 00:09:26.140 And no other project had ever won more than two golds. 00:09:26.140 --> 00:09:28.380 Which was, you know, nice. 00:09:28.380 --> 00:09:30.705 Lots of Twitter support. 00:09:30.705 --> 00:09:34.420 A woman in the UK spontaneously set up a competition for her friends 00:09:34.420 --> 00:09:35.840 with a 20 pound prize. 00:09:35.840 --> 00:09:39.689 It was a quiz about Lifesaver to get her friends to do Lifesaver. 00:09:39.689 --> 00:09:42.116 So I thought great! 00:09:42.116 --> 00:09:44.543 Because I knew all the answers to the quiz. 00:09:44.543 --> 00:09:47.220 So I thought I could score twenty pounds really easily. 00:09:47.220 --> 00:09:50.679 But she said it would be cheating, so she wouldn't let me. 00:09:50.679 --> 00:09:52.509 We've had very kind remarks. 00:09:52.509 --> 00:09:54.779 "Most powerful game experience of my life. 00:09:54.779 --> 00:09:56.640 Lifesaver. Immersed? Viscerally." 00:09:56.640 --> 00:09:59.230 One question that often bugs internet people is 00:09:59.230 --> 00:10:02.216 "Can a website make you cry?" 00:10:02.216 --> 00:10:05.202 Lifesaver answers this quite convincingly. 00:10:05.202 --> 00:10:08.189 For example: "This is the most amazing interactive site. 00:10:08.189 --> 00:10:10.980 Really emotional and effective. It made me cry at the end." 00:10:10.980 --> 00:10:13.929 And there are many other tweets and emails like that. 00:10:13.929 --> 00:10:15.945 We had a great bonus, 00:10:15.945 --> 00:10:19.279 which is the star of film three, Daisy Ridley, 00:10:19.612 --> 00:10:22.410 was recently cast in Star Wars. 00:10:22.410 --> 00:10:26.709 Reputedly as the daughter of Han Solo and Princess Leia. 00:10:26.709 --> 00:10:31.149 Now with Daisy I almost didn't cast her - because she was so beautiful. 00:10:32.028 --> 00:10:35.040 You know - we wanted, like, normal-looking people. (Laughter) 00:10:35.040 --> 00:10:38.850 But she was so good at acting I thought, oh - don't have any choice. 00:10:38.850 --> 00:10:41.989 So she was absolutely fantastic and of course she's brought in 00:10:41.989 --> 00:10:43.510 lots of new viewers. 00:10:43.510 --> 00:10:46.420 That footage I should say has never been seen before. 00:10:46.420 --> 00:10:48.816 It's not actually in the final film, 00:10:48.816 --> 00:10:51.212 so that's the only time it's ever been viewed. 00:10:51.212 --> 00:10:54.170 Okay, so that's all fine - but it's all a bit anecdotal, right? 00:10:54.170 --> 00:10:55.439 Give me some proof. 00:10:55.439 --> 00:11:01.264 A doctor did heart rate tests on someone watching two typical CPR films. 00:11:01.910 --> 00:11:05.030 Now, CPR films, like CPR training 00:11:05.030 --> 00:11:07.860 tend to be very nice and polite and a little bit dull. 00:11:07.860 --> 00:11:09.189 And you can see here 00:11:09.189 --> 00:11:12.699 that the heart rate never gets above 87 beats per minute, 00:11:12.699 --> 00:11:15.309 watching these CPR films. 00:11:15.309 --> 00:11:18.370 Lifesaver, by contrast, the heart rate gets up to 105 beats per minute. 00:11:18.370 --> 00:11:21.570 And that's the desktop version, where you're just pressing buttons. 00:11:21.570 --> 00:11:25.036 So one question I often get asked by film people is, 00:11:25.036 --> 00:11:27.590 "Yeah, yeah, yeah - but does the interactivity 00:11:27.590 --> 00:11:29.729 actually make a difference? 00:11:29.729 --> 00:11:31.697 Couldn't you just show regular video 00:11:31.697 --> 00:11:34.979 with people screaming and shouting and wouldn't that be good enough?" 00:11:34.979 --> 00:11:38.449 Well, again the data shows that the interactivity does make a difference. 00:11:38.449 --> 00:11:43.370 Without interaction the heart rate never gets above 83 beats per minute. 00:11:43.370 --> 00:11:46.259 Because what's happening is that the interaction 00:11:46.259 --> 00:11:49.592 is making you feel this is your problem. 00:11:49.592 --> 00:11:52.860 You're the one who has to save this person. 00:11:52.860 --> 00:11:55.944 And so it becomes much more emotionally involving. 00:11:55.944 --> 00:11:58.088 Much more gripping. 00:11:58.088 --> 00:12:00.923 South Bristol Community Hospital in England 00:12:00.923 --> 00:12:04.129 did tests with a random selection of members of the public. 00:12:04.129 --> 00:12:07.159 They found that confidence in doing CPR 00:12:07.159 --> 00:12:10.189 rose from 37% before Lifesaver to 74% after. 00:12:10.189 --> 00:12:13.220 And 100% of the people they tested 00:12:13.220 --> 00:12:16.987 said they were much more likely to help out in a real emergency. 00:12:17.689 --> 00:12:19.819 Okay, now Lifesaver is an idea. 00:12:19.819 --> 00:12:23.549 And it's an idea that can be applied to all sorts of crises. 00:12:24.548 --> 00:12:27.019 We naturally want to do Lifesaver for Germany 00:12:27.019 --> 00:12:29.372 for the United States, for China. 00:12:29.372 --> 00:12:30.770 We also want to do 00:12:30.770 --> 00:12:34.780 12 most common emergencies: everything from drowning to car crash. 00:12:34.780 --> 00:12:37.510 We want to do one about women's personal safety. 00:12:37.510 --> 00:12:40.060 We want to do one about what to do in an earthquake. 00:12:40.060 --> 00:12:41.225 And so on. 00:12:41.225 --> 00:12:45.186 So lots of great potential for this approach, for this idea. 00:12:45.186 --> 00:12:48.590 How many of these projects are currently funded? 00:12:48.590 --> 00:12:51.024 How many are currently underway? 00:12:51.370 --> 00:12:56.220 Not one single Lifesaver project is currently underway. 00:12:56.220 --> 00:12:58.240 We went back to the first aid charities. 00:12:58.240 --> 00:13:01.559 Back to the medical charities. Absolutely no interest. 00:13:01.845 --> 00:13:04.370 What's the reason? Well, it's obvious right? 00:13:04.370 --> 00:13:08.179 I suck. Clearly I suck at marketing. 00:13:08.179 --> 00:13:11.280 And I'm just hopeless at getting these things underway. 00:13:11.280 --> 00:13:12.947 Who could do a better job? 00:13:13.182 --> 00:13:14.569 You could. 00:13:14.569 --> 00:13:17.622 It's not that difficult to make a film like Lifesaver. 00:13:17.622 --> 00:13:20.350 It's not that different from making a regular video. 00:13:20.350 --> 00:13:22.879 There are just six secrets that we need to look at. 00:13:22.879 --> 00:13:25.965 And then you can make your own. It's not that hard. 00:13:26.369 --> 00:13:28.000 It's something you do. 00:13:28.000 --> 00:13:31.490 Lifesaver or a Lifesaver-type film 00:13:31.490 --> 00:13:36.009 is not a film that tells a story where someone has a heart attack. 00:13:36.009 --> 00:13:40.340 Lifesaver is where you save somebody who's had a heart attack. 00:13:40.340 --> 00:13:44.590 It's not a Choose Your Own Adventure story with lots of different endings. 00:13:44.590 --> 00:13:48.870 It's a film with one ending - where you save the victim. 00:13:48.870 --> 00:13:51.800 To get there, you have to fight lots of battles. 00:13:51.800 --> 00:13:55.740 If you lose, then the victim dies, you go back a bit, you try again. 00:13:55.740 --> 00:13:58.769 But at the end, you will save the victim. 00:13:58.769 --> 00:14:01.129 You need an interactive film director. 00:14:01.129 --> 00:14:03.822 Lots of interactive films fail dreadfully. 00:14:03.822 --> 00:14:07.835 And one common reason is they just get a regular director 00:14:08.974 --> 00:14:11.349 who just does the videos and then walks away. 00:14:11.349 --> 00:14:13.409 The videos are thrown over a glass wall 00:14:13.409 --> 00:14:16.610 to the interactive people, who work on it separately. 00:14:16.610 --> 00:14:19.319 And so the whole thing just collapses horribly. 00:14:19.319 --> 00:14:24.389 What you need is one person looking after the concept, the script, the shoot, 00:14:24.389 --> 00:14:26.549 the coding, the launch. 00:14:26.549 --> 00:14:29.182 So the whole thing is nicely integrated. 00:14:29.182 --> 00:14:31.670 You need an interactive production house. 00:14:31.670 --> 00:14:35.309 Now the interactive production house on Lifesaver was a company called UNIT9. 00:14:35.309 --> 00:14:37.683 And Piero Frescobaldi, the creative director 00:14:37.683 --> 00:14:42.042 and Yates Buckley, the technical partner did an absolutely fantastic job. 00:14:42.042 --> 00:14:44.049 Along with the coders and designers. 00:14:44.049 --> 00:14:46.907 And they made Lifesaver what it is. 00:14:47.885 --> 00:14:50.240 Real people gives you real emotion. 00:14:50.240 --> 00:14:52.450 Sometimes people say, 00:14:52.450 --> 00:14:54.910 "Yeah - but why not make it like a video game 00:14:54.910 --> 00:14:57.370 with computer- generated imagery?" 00:14:57.370 --> 00:15:00.370 You could. But of course then you wouldn't have anything like 00:15:00.370 --> 00:15:04.889 the same emotional connection that comes from real people in real places. 00:15:06.309 --> 00:15:09.629 And then finally, don't make it interactive. 00:15:09.629 --> 00:15:11.299 Unless you must. 00:15:11.299 --> 00:15:13.590 Linear video is a fabulous medium. 00:15:13.590 --> 00:15:15.870 You just want to tell a story? Linear. 00:15:15.870 --> 00:15:19.899 You just want to record a talk? Linear. It's a beautiful medium. 00:15:19.899 --> 00:15:25.370 But - if it's fundamental to your project that the viewer must do something, 00:15:25.750 --> 00:15:29.309 then interactivity added to video is dynamite. 00:15:29.309 --> 00:15:33.935 But handle it carefully and only use it if you have to. 00:15:35.719 --> 00:15:39.263 (Video) Paramedic: Okay guys thanks a lot, we'll take it from here. 00:15:39.269 --> 00:15:43.562 We're going to take over the CPR in 3 - 2 - 1. 00:15:48.450 --> 00:15:51.730 Woman1: Thank you so much. Woman2: Oh, it's okay. 00:15:51.730 --> 00:15:55.970 I just hope he's okay. Man: Thank you so much. 00:15:55.970 --> 00:15:58.700 Paramedic: Well done. You did a brilliant job. Well done. 00:15:58.700 --> 00:16:00.032 Woman 2: Thanks. 00:16:03.670 --> 00:16:05.377 Narrator: Shock delivered. 00:16:05.377 --> 00:16:10.070 MP: Lifesaver shows we can use the Internet and interactive film 00:16:10.119 --> 00:16:13.410 to teach emergency skills better. And save lives. 00:16:14.109 --> 00:16:14.870 Thank you. 00:16:14.870 --> 00:16:16.870 (Applause)
