Slow camera frames deciding wickets

[Big Bad Barney]

Hi there,

Was watching the T20 tonight and one of the batters got run out. He was well short, but they went upstairs to the third umpire guy who checked to see if the guy's hand dislodged the bails or the bails did.

They slowed it down frame by frame, rewound, fast forward, back, forward....the commentators crapped on the whole time..... and I dunno how fast cricket balls go, but seems to me they didn't have enough frames....the ball moved too fast...

Then I wondered why they didn't have higher frame cameras...surely they exist? or is the marketing guy in charge?

Anyway...just a thought...I was curious...why don't they have higher frame rates for the third umpire?

At 50 fps, which is the standard in Australia, this is how far the ball will travel per frame at different speeds.

I thought the Aussies were on 25 frames per second.

PAL I think is 25 frames per second, which is what all the old TVs were on in Australia

Random youtube about a 1000frame per second camera. Comments peeps say its not interpolated (i.e. no trickery, what you see is not AI'd/altered)

I suppose it's not so much the broadcast speed I was intrigued about (although that is interesting too). It's the fact that the third umpire wasn't operating on a high frame rate.

The broadcast showed the third umpire moving through, it frame by frame, and it was still hard to really see what happened as the ball had moved quite a long way between frames....

ahh interesting...that looks like spreadsheet you have done yourself, for some kind of trading endeavour

I been working on lasers to shoot down that sort of thing for years...

Edit: No. I haven't...just joking....someone probably has though....

The TV umpire uses broadcast images to make decisions rather than a special feed with a higher frame rate: “TV umpire to director…”

I imagine the cost of taking higher frame rate images, from multiple angles, with specialist equipment is prohibitive.

It’s an interesting point you make, though, and it’s an issue with VAR in football, too. The weak point in offside checks is accurately identifying the point where the ball is played forward, yet we have these ludicrous decisions where players are given offside by the tiniest of margins.

Good point, it's like when in maths you are given a result to 4 decimal places based upon data that is to 2 decimal places!

You make a great point! The accuracy of offside decisions in VAR is heavily dependent on frame rate limitations, which can lead to incredibly tight and controversial calls. Do you think incorporating AI-powered ball-tracking or higher-frame-rate cameras could be a viable solution, or would the costs and implementation challenges outweigh the benefits?
