FYI, I just posted a new video that shows how to do video analysis of stroke mechanics. You can use the approach to try to diagnose and fix stroke issues on your own. The video also shows examples of common stroke flaws. Stroke examples from pro players Aloysius Yapp (821 Fargo) and Sharik Sayed (763 Fargo) are also included:


Contents:
0:00 - Intro
0:32 - Video Procedure
2:03 - Side View – Draw
5:02 - Rear View – Fast Follow
6:15 - Front View – Cut Shot
9:45 - Wrap Up

As always, I look forward to your feedback, comments, questions, complaints, and requests.

Enjoy!
 
Nice procedure for analyzing strokes. I like that you included an overview of the checklist sheet for things to analyze that ppl can pause on to see what to look for. I did this and only thing jumped out at me as a bit odd...the follow through.

For players that are low to the cue and don't drop their elbow, the example of a 4-8 inch follow through is way too long. Case in point, all 3 of you, Yapp, and Sayed barely get the tip past where the CB was, def under 3inches. The follow through certainly is 'complete' given the mechanics you guys use so it's not like being significantly shorter than the example length is any sort of 'flaw'. I think the parenthesized 4-8" example length may look like a suggested length for follow through and may be confusing for students playing along at home.
 
I think you need like 3-4 cameras to get a good stroke analysis going, one from behind the player, one on the side and one from the front and/or overhead view so you can capture the cue, tip and stance alignment at the same time without distortion due to angles and camera sight lines or the body being in the way.

While ideal, this is just not feasible for most people. 3 shots, filmed from 3 different angles, with one camera do the same job. You just don't have all 3 angles on the very same shot but this isn't much of an issue imo.

This was not a stroke analysis video...As stated in the printed introduction it is how to do a video session to analyze the stroke.
 
Dr Dave , as always, your productions exceptional.

Since you asked for suggestions, I'll give it a try. I think the rear view is extremely important because the forward movement of the butt/grip hand is the only part that should move during the final stroke. Looking at the butt will magnify stroke inconsistencies. I would like to see your thoughts on any abnormal wrist movements here. Just a thought.

Thanks again for your contributions.

And to do a good analysis, you need several of each of the three shots.

Thank you for pointing this out. I haven't edited that document in a very long time. I just removed the example range and cleaned up a few other things. For those interested, here's the revised document:

That sure would be nice; but in a Boot Camp setting, one camera with the 3 different shots from the 3 different views gets the job done easily quickly with plenty enough information.

Agreed. The rear view can be very helpful to spot grip, wrist, and stroke issues. In the video, we showed examples of many things that can go wrong with all of these things.

Agreed. More is better. But in a Boot Camp setting, with a compressed schedule, speed and efficiency (for both filming and review) is important.
