WEBVTT 00:04.240 --> 00:09.560 In this lecture, we will present the seven variables which we want to extract from the MrBeast YouTube 00:09.560 --> 00:11.600 channel for each of his videos. 00:12.640 --> 00:17.280 Here we have an example of the seven video parameters we are interested in for a particular video. 00:18.120 --> 00:23.240 Going through them briefly, video ID is a unique identifier for each video title is. 00:23.240 --> 00:27.600 The title of the video published at is when the video was published. 00:28.000 --> 00:32.280 Duration is how long the video is and views, likes and comment counts. 00:32.320 --> 00:34.600 We have already seen in the previous lecture. 00:34.880 --> 00:40.040 Now, in order to get these variables when using the YouTube API, we have to jump to competitors. 00:40.720 --> 00:47.000 The first hurdle being getting the ID of the playlist that contains all the channels uploaded videos. 00:47.320 --> 00:51.080 The second hurdle is using the playlist ID we just found. 00:51.120 --> 00:58.160 We then get the list of unique video IDs, and once we have these unique IDs, we can then finally get 00:58.160 --> 00:59.720 all the variables we are after. 01:00.200 --> 01:04.920 To help us conceptualize this better, we can use the Russian nesting doll analogy. 01:05.480 --> 01:10.800 If you're not familiar with these dolls, they are a set of usually wooden dolls of decreasing size 01:10.840 --> 01:12.720 placed one inside another. 01:13.040 --> 01:18.100 So if we were to use this analogy and what we learn from getting familiar with the YouTube API. 01:18.140 --> 01:18.700 Lecture. 01:18.700 --> 01:22.540 When we mentioned resources, we can summarize this lecture as follows. 01:22.900 --> 01:28.260 The biggest doll represents the first hurdle where we will use the channel's resource to get the playlist 01:28.260 --> 01:28.620 ID. 01:28.820 --> 01:34.020 Once we have the playlist ID, we can open the biggest doll where there we will find the next biggest 01:34.020 --> 01:34.380 one. 01:34.900 --> 01:40.620 This represents the list of unique video IDs which we will get from the resource playlist items. 01:40.900 --> 01:46.540 When finally we get the list of video IDs, we have the smallest Russian doll which relates to the videos 01:46.540 --> 01:47.940 resource where. 01:47.940 --> 01:51.340 Here we will get the final seven video variables. 01:52.340 --> 01:55.380 That's all the theory that we will need to cover in the coming four lectures. 01:55.380 --> 01:58.940 We will translate what we learned in the previous lectures to Python code. 01:59.340 --> 02:04.860 So if we were to summarize, the first three out of the four remaining lectures represent the three 02:04.900 --> 02:07.180 Russian dolls we introduce in this lecture. 02:07.500 --> 02:14.460 So part one will focus on getting the playlist ID, part two the video IDs, and part three the video 02:14.460 --> 02:14.980 data. 02:15.300 --> 02:21.140 And in the fourth and final lecture, we will save the data we extracted to JSON, ready to be ingested 02:21.140 --> 02:22.260 into the data warehouse. 02:22.940 --> 02:25.940 That's all for now and I can't wait to start coding this up with you.
