Vertical jump hang time calculator web app

So I have been loading videos into this web app that allows you precisely tag takeoff and landing points of a video and calc hang time and vertical etc.

https://www.thehoopsgeek.com/measurement-app/#!

And a lot of jump mat videos are so inflated it's crazy.
That 47.1 vertical vid from a football combine is only 41 or so inches based on hang time...

I wanted to measure a lot of popular vids, on Youtube and instagram but they tend to slow mo the jump after takeoff... blah...

Clarence's jump back when he was 80kg, with that 200kg squat is a legit 40 inches or so on the app. Not bad for a non vert training person.

<a href="http://www.youtube.com/watch?v=8TFxoNvvsxM" target="_blank">http://www.youtube.com/watch?v=8TFxoNvvsxM</a>

another vid I tried was Rugter's Dunker's vertical on a vertec, which was supposedly 40 inches, I only got 30 inches....

^^^^
Someone who trains to a 2.5*BW ATG squat, for whatever reasons, using whatever methods, with whatever other variants, either he knows it or not, he also trained himself for(to) a top-class vertical jump too.
 ;D :lololol:
Target training paces (min/km), calculated from 5K PR 22:49 :
Easy run : 5:48
Tempo run : 4:50
VO2-max run :4:21
Speed form run : 4:02

---

it's the biggest trick in the run game.. go slow to go fast. it doesn't make sense until it smacks you in the face and you're like ....... wtf?

Clarence was more an olympic lifter back then and did a bit of tricking, but I doubt he practised running jumps as much as BBall players/aspiring dunkers do :)

I was looking at that site last week! Your thoughts on accuracy in regards to your own jumps/vids?
Insert motivational quote here...

Pretty close, but with lower jumps and 30fps the swing to either side of the measurement is quite a bit larger. Most are within 2-3 inches
Also I think timing from feet flat to feet touch landing is more accurate as the toe off adds jump height

The analysis might underestimate your vertical jump if you take off and land on your toes.

Since I land on my toes, this under estimates my jump a bit.
It matches up for me when I time from 1-2 frames before my feet leaves the ground and flat feet landing

Got a 43.7 inch jump on the above vid with the proper measurement settings now.  :ibjumping:
From just before the feet leave the ground,  to flat feet landing

accurracy will vary by up to 3 inches either way due to 30fps

---

Rugter's Dunker VJ is now 35.5

--

Johnny Candito - 35 inches

55 inch box jump from a stand still.  Used car due to lack of resources.  Video shows what a 515 pound squat can do for your vertical leap.  My vertical is around 36 at a stand still.  I am 5'7" 175lbs

vert inflation, what else is new ;f

i don't trust any jump mat numbers.

and hardly anything passes my "eye test" lol.

you know a legit 35, 40, 45, 50 etc when you see one. massive changes in float every ~5".

48.7 inches, actual jump probably would be higher due to him hitting his head and reducing the hang time!
