Hi all, I just discovered something you may all know already, but I didn't.  Thought I'd mention it just in case.   You can look frame-by-frame at YouTube videos (at least, it works on my Mac) by stopping the video and then using the right arrow key (left arrow to go backward).  Each keystroke moves you one frame.   I was looking at the London M1x final:

and at about 10:14 in this video there is a great shot of Drysdale from an angle that shows the entry of the blade at the catch perfectly.  Frame by frame, it's quite fascinating.  

Cheers,

John G

Hi John,

Thanks for the tip. In a similar vein, you might be interested in the 'Stroke Cycles' page put together by ex-RSRer Neil Wallace:
http://invernessrowingclub.org.uk/strokecycles.php

Click on the crew/sculler you want to watch, then use the left/right arrows to cycle through one of their strokes.

It's a few years old now but no less instructive for it.

Kit

I've tried on my macbookpro and every arrow press advanced it 5 seconds.

On my windows PC it does it every 3 seconds, it may be a browser thing, which are you using?

Each click of the arrow gives me 1/20 second on my 13" aluminum MacBook (20 clicks changes the time at the bottom by 1 second).  I'm not sure what the frame rate is on the video, is 20fps typical?

I'm using Safari 6.0.3 and the computer is running OSX 10.8.3

Amazing, thanks!!

Yup, that's what mine does too.  20 fps appears to be the YouTube standard.  I'm also using Safari, version 5.1.7  (OSX 10.6).  I bet it is a browser thing.  You can get Safari free for windows machines I believe-  at least I have it on an old one running XP.  I'll check a couple of machines and browsers today in my lab and report back.  

Kit-  the "Stroke  Cycles" page is excellent, many thanks for pointing me to it!

Player, more likely: Flash vs. HTML5 vs. native embedded (Quicktime).
Depends on browser/plugin but also Youtube settings.

Yes, I was wrong, unfortunately it is not just a browser thing.  I found Windows XP + Safari didn't work, Windows 7 + firefox worked, Win 7 + Explorer 9 without flash player didn't. And, to top it off, with XP + explorer 8, some some Youtube videos work and some don't.  So you are right, it looks like a player plus youtube setting issue.  Bah!
