Transcripts

as a visual effects artist when I'm

watching movies I can't help but get

distracted analyzing all the awesome and

sometimes not so awesome visual effects

on screen when I'm watching sports

however that part of my brain is turned

off until recently when I was watching a

basketball game minding my own business

and saw this a percentage tracker that

tells you a player's probability to make

a shot from that specific spot on the

floor in real time which don't get me

wrong is super cool but I missed the

whole first half just staring at it but

after that game I started noticing just

how many effects are actually happening

during a Sports Broadcast and there's a

lot and whereas Hollywood films have

months if not years to execute effects

these visualizations are being generated

largely in real time this sent me down a

big old rabbit hole and I was shocked to

find that the tech behind visual effects

in live sports is just as fascinating

and intricate as the stuff that we see

coming out of Hollywood but while visual

effects in film have been around since

well nearly the Advent of the camera

itself visual effects in sports emerged

not that long

[Music]

ago imagine it's the year

1993 I will Faithfully execute the

office of President your surfing channel

is looking for a game to watch and you

land on a shot of a green field with

some white lines on it there's guys in

different colored uniforms and you hear

two old men just rambling didn't you

coach Bert Reynolds yes I did was he any

good but other than that you have no

information it's difficult to keep up

with the flow of the game when Vital

Information like what's the score and

how much time is left is not on the

screen so it's easy to see how

groundbreaking the introduction of the

score buug was in 1994 you can look up

there always know what the score is

while a digital scoreboard may seem

somewhat trivial it was actually a giant

hurdle at the time to get the graphic on

the screen the first problem was that

each Stadium had its own archaic

scoreboard with different ports cables

and electronics and for a while

broadcast teams had to man ually solder

and rewire Parts in order to get the

score interfaces working with their

Graphics interface that's getting the

data but processing that data in the

mid99s was a whole other Adventure the

live feed of the scoreboard had to run

to a group of broadcast trucks the

graphic overlay system which at the time

cost hundreds of thousands of dollars

would take the scoreboard data and

render a rudimentary graphic that

graphic consists of two video streams

the fill which contains the actual

graphic and the all important key which

contains the transparency map that

indicates which pixels the graphic

should affect these two streams are then

input into the linear key or another

piece of video equipment that actually

overlays the graphic on the broadcast

video all that work for this now funnily

enough after first seeing it many

Network Executives actually feared the

score buug would discourage viewers from

watching the idea being you tune in you

find out the Steelers are losing by 51

and decide I'm not watching this so you

turn it off before you get invested but

viewers love the score buug and so

networks eventually adopted it

universally other sports quickly adopted

their own version of the score buug and

so began a whole new level of Engagement

with broadcast sports as well as of arms

race over who could deliver the most

compelling and immediate visual context

to fans with football being the biggest

sport in the US the NFL continued to

innovate 1998 saw the introduction of

perhaps the most beloved onscreen

graphic the digital first down line also

known as the yellow line you see rather

than a simple 2D graphic with some

numbers that beautiful yellow line is

much more elegant in how it conveys to

the viewer what the goal of the offense

is it is a literal storytelling device

this team has to reach this far in this

much time or else they lose possession

it made football immediately more

accessible to non-f football fans and

the way it works is genius stadiums are

equipped with three High game camp

cameras these produce the camera angle

we're most used to seeing in a football

game these cameras are connected to

computers that contain a 3D

representation of the field that was

captured earlier through laser scanning

now because these broadcast cameras pan

tilt and zoom to follow the action this

transformation data has to be captured

for every frame as well by updating

every frame the camera's view in

relation to the field matches between

the real world and the 3D representation

perfectly with all of this math in order

a yellow line can finally be drawn in 3D

perspective you think that's it no we're

only halfway there because the last

thing the viewer wants is a giant yellow

line drawn all over the players like a

baby John Madden scribbled on the TV get

out of here baby John the system was

designed to tuck the line under the

players while still keeping it on top of

the grass this is called color filtering

and it's done by a very specific

software that takes an average of all

the Hues of the green you want the line

to be able to show up on kind of like

green screen only unlike a green screen

these H values have to be monitored by a

technician throughout the entire game as

wether and lighting conditions

invariably change this combination of

Technologies created a final result that

was so seamless to new audiences that

many people thought that it was actually

chock that the stadium workers would

clean up and reset off camera it was

simultaneously invisible and essential a

few years later ESPN built on these

visual effects and introduced the kzone

to the MLB what a cool name the kzone

the kzone presents a simple box to

represent the batter's Strike Zone and

shows whether the pitch is a strike or a

bol simple right well it's never that

simple two cameras one above home plate

and one above first base are set up to

capture the path of the ball once it

leaves the pitcher's hand as the pitch

is thrown each camera captures over 60

ball positions per second which is fed

to a computer that basically calculates

the trajectory and the speed now we

aren't quite done from a third camera

perspective they specify the strength

Zone The Box the height is measured from

the bottom of the batter's knees to

their mid shoulder it's controlled by a

dude on a joystick who draws it for

every batter that comes up and this

camera looks for any intersection

between the translated position of the

ball and the boundaries of the strike

zone an intersection indicates a strike

now while the K zone is somewhat

controversial to fans like the first

downline it's still providing a simple

visual representation a of a critical

part of the game these advancements were

taking flat graphics and bringing them

into the game this completely changed

the viewing experience of some sports I

mean think about NASCAR what was once

blurry video of a bunch of cars driving

in a circle began to look like a

fast-paced car chase with all the

information you might need to make sense

of it right there on the screen through

the use of satellites inar sensors and

3D reconstructions of the Raceway

broadcasters were able to track Graphics

to to moving cars as well as provide

crazy in-depth information like gear

position rotations per minute speed fuel

consumption all the stuff you want to

know and plenty that you probably don't

and while these sensors have been hard

mounted in cars for a while now more

recently this kind of realtime tracking

has been brought to players in 2014 the

NFL introduced RFID or radio frequency

identification tracking for those of you

who like more words the way it works is

each player has two RFID tags one each

shoulder pad that sends out positional

data to the 24 Ultra wide band antennas

placed throughout the middle level of

the stadium lineman actually need an

extra tag on their back due to the fact

that they start the play so low to the

ground and not because they're so big

they're massive don't body shame the

ball the pylons and even the officials

get RFID tags too with 53 players on

each team and all the extra devices

being tracked that's over 300 devices

working in tandem to provide data such

as location speed distance traveled and

acceleration and that's being updated 10

times per second so imagine what is

being created in a modern NFL broadcast

you have all the players tracked in 3D

space which we can lay out on our 3D

representation of the field and now even

moving cameras like the sky cam use

real-time 3D tracking to keep the

Virtual Field in line with the real

field at all times this means more

complex Graphics can be placed on a

moving image like the blue line of

scrimmage timers countdowns and this

Insanity look at the Slime Monster oh

it's the abominal slime man but these

Graphics can also make use of those RFID

trackers to create overlays of live

statistics that are tagged to players

and 3D lines tracing routes of a

receiver and even the path of the

football and so at this point in sports

the cameras the field the balls and the

players are all almost perfectly

replicated in 3D in real time what could

possibly be crazier well volumetric

capture volumetric capture is a

technique where a subject is filmed by

an array of cameras from all angles to

generate realistic and interactive 3D

renderings it was first introduced in

golf where players were brought into a

studio to capture their swing in 3D

which was later used during broadcast

for an in-depth three-dimensional

breakdown now this application is cool

but took days to process and the

Brooklyn Nets ain't got time for that so

last year they introduced the nerse 110

highresolution Canon cameras were placed

around barlay Center to capture the game

that data was used to generate realistic

renderings of the players and

environments in a matter of seconds

allowing the viewer to direct a virtual

camera wherever they want on a CG Court

seeing angles that were never before

possible

[Music]

future but why stop at just capturing a

real game why not add your own skins

your own environment and fully customize

an entire game and broadc

well that's exactly what Disney did just

this past year during an NFL game

between the Falcons and the Jaguars the

entire football field and all the

players in this game were brought into

the virtual world in a Toy Story themed

environment you had colorful Trails

behind the ball and the players Slinky

as a first down line and even the

commentators as toys look at them

sitting there in their little motion

capture suits it's adorable it was a

culmination of all the technology we've

been discussing like a proportionally

accurate CG field RFID tracking of the

players and the icing on this cake a

machine learning algorithm trained on

human motion that Faithfully applied

animation to all the toy players all of

this was being piped into the unity game

engine in order to be rendered and

played back at only a 20 second delay

from the live game broadcast that's

pretty good considering they're

converting a real game into a literal

video game now growing up I always

believed that as graphical capabilities

grew Sports video games like NBA 2K FIFA

and Madden would look more and more like

real life but the inverse is proving to

be true we now have the capability to

take a real sports event and replicate

it almost perfectly in the computer

giving us the ability to visualize any

piece of information view the game from

any perspective or just make the whole

thing look like whatever we want

anything is possible but if anything is

possible that begs the question when do

you stop adding more you see sports

broadcasting is currently in the same

boat as Hollywood and as we've learned

this last year with some massive box

office bombs just because you can do

anything with visual effects doesn't

mean you should looking at you flash

what's he talking about in both

Athletics and film gimmicks and

spectacle only get you so far what

viewers really care about is the story

an athletes Journey their rivalries

their struggles and their triumphs

it's about the unspoken narratives

etched into each play the stories in

sport are what pull us in and keep us

watching it's what makes Sports

Universal and visual effects should

serve Above All Else as a tool to

connect us deeper to the heart of that

story and as we've seen the

technological innovations that have

stood the test of time have done just

that so the next time you turn on a game

or throw on a match take a moment to

appreciate all the visual storytelling

that is hiding in plain sight and heck

maybe even tip your cap to The Unsung

artists and Technical Wizards behind the

scenes who are pushing us forward and

making all of this possible researching

this topic was such a good time if you

guys have any other topics you'd like us

to take a technical Deep dive on let us

know in the comments down below but in

the meantime I got a fake game to

pretend to watch so get out of

here oh we should have scored that goal

a I'm gonna this is I'm going to bring

this into my home life I'm going to take

this out on my the people closest to me

Sports make me feel
