Slo-mo string action.....

[Guru]

I know that slo-mo shows a lot that we don't see with the naked eye....but...

Do you think it is normal that there's such a big "loop" above the arrow?

I ask only because I never seem to be able to get the "nock high" out when tuning...

The way you shoot--I wouldn't worry about it.lol.

Pretty cool Curt, I wonder if the loop is formed because the string silencer is traveling slower than the string itself due to it's higher air resistance.

Interesting video. Strictly as a guess; I would think the 'loop' forms because the string hand is higher than the middle of the bow.
It is cool watching the string go through its gyrations regardless of the 'why'.

[T Sunstone]

I think what you see ( loop ) is mostly from the wide angle camera.

[Hermon]

I read somewhere that unless you are using "professional" quality video equipment, that in slow motion it is "averaging" the frames or something like that.  It gives a misrepresentation.
As T Sunstone said, it could be from a wide angle lens too.  I am no expert by any means.

It appears that the initial thrust of limb recovery caused your arrow to go forward, fast, and that speed of recovery lagged behind the arrows speed of carrying the string forward, until it caught up.

If so, that brings into question the aspect of longer power stroke.  As seen here, in this one motion photo, the "power stroke" was not continuous for the length of the drawn shaft.

Hmmmm

One thing that stands out to me is the apparent downward bend of the arrow as it is drawn.  That MAY be due to the camera/lens optics involved, but IF the arrow is being bent down by the draw technique, that will make it "bounce" upward giving that tail high arrow flight that you see in the video.

Again, hard to say for sure, but this is common to vertical (nock high) tuning problems.

In the video of the pheasant hunt a couple of days ago, when they showed the shot in slow motion, their string had a lot of movement.

[T Folts]

I would say it is normal, video the bottom limb and I bet it does the same or similar.

I have seen a couple videos that show way crazy string action. It is normal from what I have seen in the other videos. It just happens so fast, we can't see it.

There was one video I have seen that will make you wonder how the string ever stays on the bow when shot!

Thanks for the video! Fun to watch and speculate what is going on.

what did you record that with?

I can't offer a knowledgable opinion on this question, but that is amazing, Curt. Thanks for sharing it.

Yea Curt, that lens has a bit of a "fish eye" convex to it and may be distorting the image of the string a bit.  JMHO

[Guru]

Some good thoughts here fellas....

Terry S....I believe some of it is, but I believe it's not a whole lot because it would be distorted on the way back as well.

Moe bow, I believe the the slight bend is from the "fisheye" effect of the lens.  I don't have the nock high problem tuning any of my other bows.

Jim G., it was filmed with a Sony Action cam in slo-mo.  Then I slowed it some more while editing.
I plan to do a whole lot of cool stuff with it in the future!! Really a cool little camera...

Curt, I'm guessing but a couple things stand out from the video, 1. one is it looks like the camera is fish eye from the  arrow, it has a curve in it as well, 2. The beaver balls seem like they are holding the string behind due to the difference in aero-dynamics of the two causing the large bow in the string(would be nice to see if the bottom of the string is doing the same at the silencer!

     
   

Curt, what is that hanging off the back of your silencer, wind checker, maybe a drag factor as well?

Thanks for sharing, cool video.

Ha! You may change your mind when you see the next clip I'll post later      

[Hermon]

I still think it is some kind of distortion either from the lens or the slow motion program.

Given how a bow works, I don't see any way that the arrow can be going forward and part of the string is "lagging" behind.  Now side to side as it comes off the fingers I can understand, and as the bow comes back to brace as the arrow leaves I can understand, but not what we are seeing.

On an unrelated note, your slow-mo video also shows a great example of how to properly continue to pull through the shot to its conclusion. I wish I could do that. I always seem to pull to my anchor, stop and then release. Nice form!
