What do you want to see in SloMo?

I've heard of a technique wherein a player uses a jump cue (or break cue) in order to avoid a double hit when playing a very soft, very short safety shot when the CB is near the OB, and both are near a rail. It seems that the hard tip makes it easier to "tap" the CB lightly, thus allowing the shooter to "stroke" a bit more confidently while still avoiding a foul. That got me thinking...

Now, if we combine hang-the-9's request (jump shot with follow) with 7forlife's request (avoid double hit on close follow shot), I wonder if it would make any sense to use a jump cue to successfully hit a legal follow shot (with minimal actual jump) when the CB and OB are close together. It would be unorthodox, but might just be worth a try. Hmmmm.... I'll have to add that to the list and see if it's worth trying...

As Dr Dave mentioned, I think his videos have the double-hit request well covered, but I'll add hang-the-9's jump with follow request and the idea mentioned above.

SilverCue, honestly, I don't think I have the skill to shoot that shot, but I'll try my best. I seem to recall seeing a video on Facebook where a guy lines up on a draw shot with the cue tip very close the the CB, before removing his grip hand from the cue. The shaft rests in his bridge hand and the butt of the cue lays on the rail. He then uses his foot to literally kick the bumper of the cue, thus getting immediate and substantial acceleration on the cue, and successfully executes the shot. Perhaps I could try that technique to accomplish your request... I'll definitely give it a shot - I've been wanting to try that anyway. :)

One thing I wanted to mention to everybody: Keep in mind that my SloMo cameras max out at 1000 fps, and at that frame rate, the resolution is very very low. Since tip-to-CB contact time is in the range of 1/1000th of a second, I doubt that we'll be able to glean much information about variations in contact duration using these cameras. I really think we'd need a framerate of at least 10,000 frames per second to be able to make use of any tip-contact-time experiments.

I've had my eye on a new $6000 SloMo camera that can go up to 18,000 frames per second with decent resolution (as well as very good frame rates even in HD). Before this model was introduced, you'd have to pay a minimum of $25,000 to get a camera with that framerate. Hmmmm.... There seem to be several pool-related Kickstarters popping up these days. Perhaps... Maybe... I can dream, can't I? lol ;)

Seriously though, thanks again for the ideas. I'll definitely be challenging my pool game as well as my video skills for this project!

BTW, the "follow jump shot" would have to be follow, not just the momentum of the cueball going forward after contact. I mean the ball is spinning forward.



Otherwise the follow jump shot is not really follow. You can follow a ball with draw too if you hit it softly enough and it start rolling before it reaches the object ball.


I hear ya, loud and clear. See my post in the jump-follow thread you linked to...

I am very disappointed in the entire AZB community. I expected a much more puerile set of responses to SloMo's inquiry.

I don't have my dictionary with me, would a puerile response be like "I want to see a masse shot" or more like "I want to see Shanelle breaking"? LOL

Agreed. Many of the things people are asking for (including me) are possible only with 3,000-5,000 FPS or faster.

How about a look at the shooters eyes at the moments just before and after tip contact with the cue ball. Is the shooter looking at the target on the object ball? Or, have their eyes started to dart towards the intended pocket. If the eyes move towards the intended pocket, does this affect aim and delivery of the cue ball to the correct contact point on the object ball?

A good friend of mine swears he suffers from these "darting eyes". He feels it causes his stroke to physically move off target slightly and therefore missed shots.

Thanks,

While good to see on tape, this is a known fact, if you are looking at the wrong target, you will tend to miss the shot. Say you have a ball to get by on a close hit or need to sneak by a ball to a half open pocket, if you start thinking about and looking at that ball, you are probably 90% chance going to hit it. If you start to look at the cueball path you want to take on a tough position shot and take half your mind off making the ball, you will miss a lot more. I've missed shots that were basically in the hole because at the last stoke I looked at the rail where I wanted the cueball to hit instead of the contact point, and I've watched a player do that exact same thing just a day ago. He was aiming, aiming, aiming, then at his last stoke his eyes went to the side to look at the pocket or where the cueball is going, or whatever, and he missed.

Many instructors, once you get to a bit advanced level of skill, talk about your eye motions as much as your stoke and aiming as being part of being able to make a shot. I have a hard time to really focusing on the contact point all the time, but when I do, the shot goes in pretty well, if I focus somewhere in the middle of the table or on the cueball or past the ball, I do miss more, and kick myself for doing it.

1) beauty of a genuine slip stroke, the way the hand slips along the butt sleeve, from a player who's been using it naturally and most of the time;

2) the way various pro players grip the cue, as filmed from behind and from the inside part. How their grip works during cue delivery;

3) jump shot from the distance of a credit card between the cue ball and the obstacle - to prove that there is no way to execute such a shot without a foul (cue ball rebounding from the shaft). It usually causes debate and such a slo-mo video is supposed to end this once and for all
 
Even though we already know how speed effects a balls angle of deflection after hitting a rail, would it be possible with your camera to see how much a rail actually compresses at various speeds?

Another shot I think would be interesting to see in slow motion would the 14.1 break shot where the cue ball is behind the rack and you shoot the corner ball banking it cross side.
