15:10Um and by the by the judging by the size of that camera, like that's not like one of these like 100 frame per second cameras right? >> So, to get the the timing down >> of when the ball was hit. >> of when the ball was hit. The ball actually has an internal sensor. It's a 14 g sensor, an inertial measurement unit, an IMU, that's used in like gyroscopes and things like that for airspace. In this case, they stuck it it's inside the FIFA ball like just beneath the surface. That thing takes data at 500 Hz, 500 data points per second, and it's measuring acceleration and things like that. So, when you hit it, you'll know within 500th of a second when the ball was hit. So, now you can
15:50finally get the the um >> like a level of resolution >> down to that size. So, now when they show that line, that line has a thickness of about a centimeter or less. Otherwise, it should be a blurred out line. >> Right. It would be >> Because I don't know where the where the ball was when the ball was hit. >> Yes. >> Right? So, that kind of made sense. And combined, this gives the comprehensive VAR system. You've got the 500 Hz from the ball, you've got these 3D positions from the players, and that's where you get that line. >> And and so, when people hear VAR, they think And they you it did used to be this way where it was just some some people in a room and they would draw
16:30lines manually >> Yeah. >> on on the video. >> on a video >> with at an angle that was not the correct angle. It was all these things. >> Yeah, all these things. And it's like I But now it kind of makes sense. >> it's it's it's actually >> the amount of data that's going in, I can understand if the error budget is for like that thickness of the line is like way smaller. >> reasonable. >> Yeah, it's reasonable. >> Now now again, in the World Cup, not in all leagues in the world, not club level, that everyone's a little different, but specifically for the World Cup and their VAR system. >> Yeah. >> Yeah. >> And so, I wasn't done there because this got me thinking about other stuff. Okay? Like for example, you've got the sensor that's in the ball. How come the sensor
17:12is off like to the side just underneath the ball surface. >> Yeah, yeah. Um and if you look at the 2022 World Cup, that also had a sensor, but it's at the center. It's suspended at the center. That kind of naively made sense to me, but off to the uh just under the ball
