WEBVTT 00:00.110 --> 00:05.390 Let's now see how to take a video from the terminal with the Raspberry Pi camera. 00:05.390 --> 00:08.660 And this one is going to be quite easy if you understood how to take a photo. 00:08.690 --> 00:11.870 While taking a video is not going to be that much different. 00:11.870 --> 00:17.300 So we had the RPI cam and then Dash still for the photo. 00:17.330 --> 00:23.690 Well, for the video we have RPI cam, Dash V and then the same thing as before. 00:23.690 --> 00:31.820 If we want to actually save the video in a file, we need to provide the output with dash o. 00:31.880 --> 00:39.860 I'm going to go inside the camera and then name it uh, video tests for example dots. 00:39.860 --> 00:42.530 And I'm going to use the MP4 extension okay. 00:42.560 --> 00:44.720 So that's going to be a video file right. 00:44.750 --> 00:49.160 So RPI cam video with Dash oh option for output. 00:49.160 --> 00:53.000 And we provide an MP4 extension for the file. 00:53.000 --> 00:54.320 Let's press enter. 00:54.320 --> 00:54.980 Let's run that. 00:54.980 --> 00:56.510 So it's going to open a preview. 00:56.510 --> 01:01.860 And and what you see what I can put my hand I can do some movement. 01:01.860 --> 01:05.730 We have something that should be saved in the camera folder. 01:05.760 --> 01:06.300 Yes. 01:06.300 --> 01:08.220 So I can play that one. 01:09.570 --> 01:11.280 It's going to be for five seconds. 01:11.730 --> 01:11.940 Okay. 01:11.970 --> 01:14.160 So it's moving because my table was moving. 01:14.160 --> 01:15.900 But okay. 01:15.930 --> 01:18.690 You can see it's working once again. 01:18.720 --> 01:21.990 You can see the well it's upside down. 01:25.110 --> 01:28.320 So I can use the same option as before. 01:29.130 --> 01:30.420 I'm going to play it again. 01:30.420 --> 01:39.330 And I can use the v flip and H flip to do a vertical flip and a horizontal flip. 01:39.330 --> 01:41.400 So let's run that. 01:43.470 --> 01:43.980 Okay. 01:43.980 --> 01:48.840 And now you see the camera is correctly orientated. 01:49.020 --> 01:51.960 And we can see that on the file as well. 01:52.890 --> 01:56.580 If I play the video okay it's working well. 01:56.580 --> 02:02.650 And now if you want you can also modify the resolution with the same options that we had before. 02:02.680 --> 02:08.710 So if I come back to the previous command, you see, we have the dash dash width with a number and 02:08.710 --> 02:10.810 then dash dash height with a number. 02:10.810 --> 02:16.780 You can use the same for the camera, but here actually we might not even need to because well let's 02:16.780 --> 02:17.890 look at the logs. 02:17.890 --> 02:19.330 That's a lot of logs okay. 02:19.330 --> 02:20.560 But okay. 02:20.590 --> 02:22.900 The information is in a few places. 02:22.900 --> 02:29.800 But you can see for example here we have the while the video stream that's with this resolution okay 02:29.830 --> 02:32.650 640 times 480. 02:32.680 --> 02:34.270 So that's 480 P. 02:34.270 --> 02:37.360 That's the default resolution for the camera. 02:37.360 --> 02:38.830 It can't go higher okay. 02:38.860 --> 02:39.970 So it can go higher. 02:39.970 --> 02:41.620 But the default is that one. 02:41.620 --> 02:43.990 So it's already quite small okay. 02:44.020 --> 02:47.710 So if you want you can increase actually the width and the height. 02:47.710 --> 02:51.850 So you can increase the resolution with those two parameters. 02:51.850 --> 02:57.400 But here I'm going to keep it like this because we have for example for five seconds we have just 500kB. 02:57.400 --> 02:58.750 That's quite small okay. 02:58.780 --> 03:03.740 And in the end you don't need actually for many applications you don't need a high resolution. 03:03.740 --> 03:04.490 You might need that. 03:04.490 --> 03:05.690 You need a high resolution. 03:05.690 --> 03:11.930 But high resolution is needed for like for example, if you want to shot a movie or a video that people 03:11.930 --> 03:12.740 are going to watch. 03:12.740 --> 03:19.040 But anything that you use for, let's say, a security camera or even to do image processing, if you 03:19.040 --> 03:24.440 want to recognize a face or some object, you actually don't need a high resolution. 03:24.470 --> 03:31.430 Okay, so 400 and ATP, I would recommend to well, if it's the default one, just don't change it. 03:31.490 --> 03:33.260 That's probably going to be enough. 03:33.260 --> 03:34.520 And just one last thing. 03:34.520 --> 03:40.010 So here the video where I told you it's going to take a five seconds video. 03:40.010 --> 03:43.580 If you want to modify this you can add a dash T. 03:43.610 --> 03:45.650 So that's going to be only one dash here. 03:45.650 --> 03:46.340 Dash T. 03:46.340 --> 03:49.640 And then you need to provide a milliseconds. 03:49.640 --> 03:56.330 So for example if you want seven seconds that's going to be 7000 milliseconds okay. 03:56.330 --> 03:57.830 So you add a dash t here. 03:57.830 --> 03:59.990 You can add a dash T before okay. 04:00.020 --> 04:02.780 The order of the parameters here is not important. 04:02.790 --> 04:04.320 So let's press enter. 04:04.350 --> 04:07.440 It's going to take a video for seven seconds. 04:08.760 --> 04:09.060 All right. 04:09.060 --> 04:10.800 So let's wait a bit. 04:12.330 --> 04:15.450 And now we have a new file. 04:15.450 --> 04:17.460 And it's going to be seven. 04:18.810 --> 04:19.830 So it shows six. 04:19.830 --> 04:21.840 But it's it's going to be seven. 04:22.320 --> 04:23.010 All right. 04:23.610 --> 04:27.450 And you might wonder why we have only one dash here and two dashes here. 04:27.480 --> 04:31.350 Actually all the commands have two dashes. 04:31.830 --> 04:35.490 For example that one is dash dash output. 04:35.490 --> 04:38.880 But for some options there is a kind of a shortcut. 04:38.880 --> 04:41.760 So usually you have the full word like this. 04:41.760 --> 04:46.770 And then the shortcut is just dash o which basically means dash dash output. 04:46.770 --> 04:53.640 And the same for dash T I think the full name is going to be dash dash timeout. 04:54.570 --> 04:55.140 Okay. 04:55.170 --> 04:56.880 But you can replace with dash T. 04:56.910 --> 04:59.370 So sometimes you have the option sometimes not. 04:59.400 --> 04:59.850 All right. 04:59.880 --> 05:03.750 And now you know how to take a photo and a video from the terminal.
