Using 2D photos to create a 3D model which can settle the question: Was he or she offside?

The first Philadelphia Union goal against Columbus Crew back on May 10, from the free kick? I have it as 8 inches offside. Honestly, a _lot_ closer than I expected. Still feel like VAR could have intervened but this info makes it look less obvious than I originally thought.

The Atlanta United goal against @austinfootballclub.bsky.social back from almost a month ago? Sorry for the delay, but it looks like it was onside. Only by 3" by the model, but no reason to think it wasn't onside from this

The offside in El Traffico? That took LA Galaxy's Gabriel Pec's goal off the board? I have it as 9-10 inches offside. That's with a relatively conservative guess on position of the 2LD, so could be more.

That @nashvillesc.bsky.social goal line situation? I have it as 3/8" inside the goal. Given the difficulties of the model and esp. goal-line situations, I can't be sure that it was or was not a goal.

Which means that the GK cannot be challenged on a drop kick that actually occurs outside the area because they are considered to be in control of the ball with their hands... but it is not a handling offense b/c he isn't touching it with his hands.

There is some confusion sometimes for a GK cannot be challenged by an opponent while the GK is "in control of the ball with the hands". Throwing it in the air, as part of a drop kick, is considered in control with the hands.. so an opponent cannot challenge the GK on drop kick.

He releases the ball well prior to leaving the area. That he may kick it outside of the area is not a concern.

In order for the GK to be considered handling the ball outside of the area he would have to have the ball in his hands with the entire ball outside of the yellow line.

Alright, so if you can take a screenshot of the right frame and post it, that should work.
Windows: ⊞+S
Mac: ⌘+⇧+5

To step by frame in Chrome go to the Dev Tools and use this in the console:
document.getElementByTagName("video")[0].currentTime += 1/24

-= (instead of +=) goes back a frame

If you have a link to the original video? I can't do it off of a recording of a recording (it is a transformation of a transformation)

It's been a while, I've been busy, but hoping that things have calmed down and I'm able to get these done in a reasonable amount of time

OK, so that St. Louis goal against Columbus called back? I have it as 6 inches onside.

I will say that it's harder than it looks b/c 2LD here has his foot off the ground so it isn't as easy as just following the lines in the grass.

That's the implication at least. In practice it seems that it largely depends how my analysis intersects with your favorite team(s)

So here's how it works
1) You send me an offside call you want me to model (minute is really helpful)
2) I pick a few when I have time, do them
3) You love me forever
