Frage von Blackeagle123:
Hello,
erstmal to the title: klarm, Steadicam wins next Chestpod Magic! But:
I need for a wedding (the inlet of the bride) a recording, when retracted, the camera ". Yes, Dolly and steadicam hab ich nich, is synonymous to me too expensive! Have only one shoulder, "tripod" to wackelts but soon more than without:)
So my question is: What do you think of the Chestpod Magic of Cullman?
Is that even a kind of substitute for a Steadicam? Build (even I want me a Steadicam synonymous nich in nem Dolly I've already considered themselves to build, but put in the church rail I'd rather just ask gar nich * g *)
Can it turn good jolt-scenes? As it turns such a scene?
Many dear greetings

Hi Constantin,
Steadicam one need not be necessarily connected with the body. This is done primarily because of the high weight of professional stabilization systems, thus being able to work without tiring (well!) And can move to other better.
Part of such a Steadicams is a well-padded corset s.dem the arm is attached, which ultimately is with the Steadicam camera. The spring arm compensates for body movement, but one must practice a lot, of course, synonymous to control such a system.
Steadicams there are quite a good example of

Antwort von djoesch:
I have my own Steadicam synonymous to tinker together with a colleague. And the results are the bright madness. I
I would love to document my experience a little bit, to perfection as we have encountered some problems, which, of course, when you know it before, can escape.
First of all, we had the advantage that we knew the boss of a company's aluminum, and container were allowed to dig for Restaluteile indefinitely.
zum Bild It is important that the joints of the spring arm are stored well. Simple bolt pretty quickly zerscheuern the aluminum and the arms of unrecognized and slope to the left, which pushes the weight s.meisten.
To solve this problem without expensive needle roller bearing, and because in a normal MiniDV Cam as SonyVX1000 enough anyway, we have gebort Alustangen the first holes, then sawed stainless steel tubes and stainless steel pins inserted dealt with the tap, so that we fit on both sides Screw on nuts could - s.diesen ends, we have the feather diagonally excited to be able to vary with screw and wing nuts to the tension of the springs. (Springs of Obi). For the pivot bolt, we used something nobler jacks, you get in the metal trading for $ 5 á. These are selbstfettend cast. The spring arms go great with some sprayers WD-40. We thus have no more jamming. For the main bar we were worried but then a ball bearing from the scrap metal. The rod 2 is adjustable in 1 and top and bottom. A steadicam would come of the horizontal to the vertical in 3 seconds. This is the perfect weight balance. Below is the lead acid battery and the LCD monitor. TFT monitors are cheap s.ca. 80 EUR available. However, caution - many LCDs on ebay are total junk and have no good Hitnergrundbeleuchtung, so that one sees in the open really nothing, especially in the sun - 130 EUR should be hinblettern already s.besten a 16:9 display (www.elv . com or www.conrad.de)
A vest should preferably run over shoulders, chest and abdomen, because the weight can make one to create very straight and the angle must be s.besten to exploit the system.
Soft step sequences have to train yourself - it's just very important - the camera would best be moved up in all four directions - so that the exact center closely as possible. But it is not to say that they ONLY get with the perfect material balance of good pictures.
The final difference with a hand-held Steadicam is that a structure held in the hand while walking ALWAYS unchecked left / right movements making. With a spring-loaded with construction joints, this is only bad weight case, or in poor storage conditions. Running one car sways to the right and left, the FullRig system compensates for this.
The important thing is you have to get the feeling that the Cam is a part of the body. Pans and rides are Object-oriented, but at the same time one should dominate at the beginning of a journey to accelerate and decelerate slowly to the end - the whole is very aesthetic, like a dance.
The overall point without camera, with equipment, LCD and Battery amounts to approximately EUR 200.
I practice it often s.einer wide long staircase in our village s.der church. My colleague is running, or running up the stairs, or down, and I follow him, run around him and try to have him always in the correct image position.
For objektnahe trips I use a 0.5 x Wide Anglevon Raynox or 0.7 x. Even without wide Anglelässt to do many, but it always seems a little uneasy, less for any wobbles, but rather because the human eye so synonymous contribute a kind of Wide Anglebesitzt and desahlb dense long tracking shots somewhat unnatural to the eye. (so I explain that) Of course, mean that the larger the Wide Angleist, the finer the rides look like.
Important synonymous - it should once you wrap on the floor - ouch!
Filmed in the vicinity of water without a system where you can open by pressing a button, the entire vest, is lethal. Also running on increases, it is quite threatening risks associated with - but is clear

Antwort von djoesch:
So - there really are only ONE Steadicam system, where you can truly say that it is the effect of what it should.
One would have the camera feel s.Körper performing yet quiet and smooth driving motion. This was the first of Garret Brown developed for the film "The Shining" with Jack Nicholson of Stanley Kubrick.
I can only recommend the DVD containing a making-of, where you can see something is usdamit fashioned way. Often, you want so synonymous between two chairs, or through narrow passages, where one thing on wheels or tracks are sometimes a hindrance. This part of your Handycam with the weight that you hold in your hand, I had built myself auchmal, but is really a joke in the Comparison and must in my opinion, not at Steadicam be named. It helps a little with
Certain irregularities in the movement, but it still remembers that someone with that thing running. Among the steps that we do, we stagger of one leg to the other, how will you compensate for this, if you have found the camera still in hand?
In the right system you lead, the camera only with the hand, although
there is not the typical stage movements, because the weight distribution and provide a balance to ensure that the effort is too short to cause a wobble. (hope this time it is true)
And the feathers always counteract the forces that cause the shaking else. I'm going to give up his feathers - I'll go down to draw together the feathers and the camera goes up. Thus, the perfect balance. :-)
The principle I have rough times together.
http://daniel-joesch.de/steadycam/
Through this plan, it is entirely possible to build something very reasonable.
There is the opportunity to set the feathers, or the
To make spring construction with a spring in the middle, instead of two without. Or you can distribute the springs with wire rope over pulleys in a Z-shape and could thus have the ability to install per arm part 3 springs, which are simply connected by the wire rope and the pulleys.
Important synonymous, the more difficult is the construction of the weight, the calmer the rides. In general, I would create a 0.7 x Wide Angleempfehlen.
The result is always very significant, it was run by stairs or other obstacles, or just completely straight people to follow on the road.
Enjoy! ;-)

Antwort von GhostDog:
Wait!
For right / left, there are no feathers!
You need two spring-loaded arms.
The first arm is the gross motor skills for the reception and the
Second call for the poor fine motor skills.
The springs are generally so gestpannt the arm straight out in front shows the urge arm very slightly to the bottom.
The individual arms can be made into any position.
To attach the right and left springs garkeine makes sense, since there is no fixed "gravity" is in this direction. The "gravity" is not constant and can be tricked by the springs.
With right and left - wobbles, there are no problems, because it is used as the "inertia". The total weight is strong enough that it wobbler no longer exists. If you loose the Steadicam, and you can rotate the avatar to the right or left, it remains s.ihrem place - because of inertia. I have the SonyVX 1000, and the synonymous does not weigh much more than 1kg. You can stick the boot synonymous extent that it is longer than the top down. So you can use the heavier weight down with the top bring back into balance. It is important that you try the absolute center of the weight distribution on the center of the rod to get.

What happened with my entry? He is now twice? The second of "anonymous" is certainly easily corrected ... :-)
Antwort von djoesch:
Here to illustrate - the arm (that actually consists of two parts, an arm yes, so I am speaking of an arm)
The following is an example - my design is somewhat different ...
Here, the feathers are in fact on the inside, which saves some space in the Width.
To clarify it a little too - if you install springs for the right and left, you automatically regenerate wobbler - you make an about-turn and the spring moves back s.eine different position, so there is a wobbler. Without feathers for right and left, the principle of inertia ensures that the camera remains s.ihrem spot. The gravity / gravity is, however, has a continuous solid strength that pulls down, thus acting contrary to the springs always in the correct thickness.
Best example: Your car has an open door - you're going off - pop the door right away - because they want to stay because of the inertia s.ihrem place ";-)
So there's really only Steadicams with up-down feathers.

Antwort von Blackeagle123:
And I have the "Steadicam" of the built Hobbythek
http://www.hobbythek.de/dyn/16602.phtml <- here!
zum Bild here is a Picture of the floating tripod!
I was actually going to build this system s.den arm!?
Think it, that makes sense? Would then stop at a very well balanced!
And I wanted to build me some bracket (I'm still thinking how I place) that one pipe, so the holder of Hobbythek, steadicam, can be easily removed and the schwebestativ synonymous can use without a waistcoat! -> For any small Spontanaufnahmen ... [Perhaps my pipe clamps or something (?)]
Again, my two questions:
-Have you any idea how I can do that? (I s.deinem arm that is synonymous no fortifications seen ...)
-Is something meaningful that I made these Steadicam Hobbythek since the turn build?
Antwort von djoesch:
So the principle of the Steadicam is s.Körper ...
The spring arms from the same steps.
One uses the hands to rotations, inclinations, to make pans - you rotate your body 180 degrees and yet the camera still shows because of the inertia in the same direction. Man kan is the feeling of driving on his fingers and leaving the camera movements do not contribute roughly like a floating tripod .... In the spring arms will not work without some kind of vest, because of the leverage. The whole must remain straight, and indeed should not also charge your hips. The camera can be small, synonymous with little weight, but the longer the arm, the greater effect still a force. In a real Steadicam, it is synonymous then the vest, arm and Camera / Monitor Paper (bar) are separated from each other and are stuck. First, one puts on the vest, then comes the arm on it, the clutch with ball bearings and rod. I do not think that can stand the suspense and the spring-Steadicam combine a meaningful way.
Certainly for the short, simple shots Hobbythek-suspended stand a solution for a couple of wobbler and in any case much better than simply in your hand, because here only synonymous inertia is used - but not the on and off - and not synonymous the left and right, this happens automatically when running.
For the construction of a Steadicam You will need 4 weeks +. If you as the occasional evening and Full Time s.Wochenende doing.
It pays to go about it, because if it is done, we want nothing else. Except maybe once nen crane with wheels. That would then supplement. :-D

" Hello! Yes, I think so synonymous ...
but if I stand in front suspension s.The Steadicam off build, so instead of a rod suspended Hobbythek the stand, how does it from?

But I believe you, you can not quite imagine how the whole looks and works. If you stand the suspense on his arm "is" how do you want the camera, then turn left and right turn. Therefore, the ball would be stuck in the the bar. Just as little can you then put Cam on the head. But it's not at it then move ...

Yes, that's true .. I could be on the ball, they tend to be minimal. I can even rotate the camera to the right and left. Low incline I could they synonymous. But turning on its head, that I can not! I thought I made that I could build a system so simple that the whole suspension system is rotated so that other people are synonymous could stand on his head ...
I just think it makes no sense ... I can tilt the camera (through the ball joint) in all lean angles and positions, and the front / rear bring. With the arm up / down ... Because I would have saved the ball bearings, ball joint use indemich ...
My problem is that I can really imagine nich so!

Antwort von djoesch:
An attempt is worth it. You can then determine whether something is still disturbing. If you have the design with the spring arm s.Körper certainly is not much more to rebuild.
What may work well, and what I would try not synonymous, is buying a life jacket and then rebuild them and rivet with aluminum parts to. That could save some work.
Yes, although you can pan and rotate with the arms in gewisserweise thereby. But you can not hold the position without bearing the Camera and the Camera of turning his focus to the right and left. If the tube in a ball, you can rotate the camera in 360 degrees, for example.
Moment - I'll find out you a quick picture.

Antwort von djoesch:
Here are a few examples to illustrate the function has the ball bearing - ball bearings are available in metal scrap or cheap on eBay.
You see here that the ball is surrounded with a ring that holds the bearings - this ring is in turn connected with a U-part that makes the tilting movements. The underground part itself is connected with a screw to an arch part, that puts you up on it s.Armende.
All in all, ensures that the camera can be placed on any X-any position.

But now another question, because this is still my only problem:
How did you do the head? So you can do with your Steadicam different cams on it and then adjust the balance in some way, or did you just above a plate, in which only a hole for your cam in it?
Because there are indeed systems where the camera is the front / rear / right / left to move to find out the exact point. For example, a tripod is now extremely expensive! (On ebay I've seen this for around 200 ¬ ...)

Antwort von djoesch:
Above the pipe is just sawed off. Then a straight hole by two angles and bolted front and rear. Then a long U-piece is on top and with the U s.den pages is in the middle of a hole for the locking screw. The holes are fitted with screw threads. Then an opposite U plate on it comes, which was milled cut a long slit on the side and. On the plate itself is in the middle of a column of milled left to right. From below, the camera would then screw the camera up to the plate adjustable on the left and right. The upper U-section can now be placed on the bottom to be (one of the underground parts must of course be wider, that they take each other). Now you can screw the camera onto the side reindrehen the upper U-part screw, with the camera's threaded screw that is slightly open, adjust the left and right, then take note - and take seitelich like on a rail to the front and rear, and then tighten the side screws . Until it is well poised.

Constantin Hello,
just make OJ on the TG time and write down all formulas, so are in the physics formulas.
So, at first mass * 9.81 = Newton
D is the spring constant
m is the mass
l is the length of the spring
v is the frequency
D = m * 9,81 / l
v = 1/2PI * the root of 9.81 / l
Potential energy of a stretched spring
s is the distance of the strain
W (pot.fede) = 1 / 2 * D * s ²
normal W (pot) = m * 9,81 * h
h is the Height of the body from the zero level (h = 0) is lifted
I do not think that you with all the formulas come next because it Bachten at all the stuff not only the weight and the gravity pattern, but other paramenter.
My approach would only times the weight which the individual springs is measured and then calculate the resulting potential energy that each spring must summon. But I question my old physics Prof synonymous times how he would tackle the issue. Else comes to me the "h" should remain close to zero, which would of course only an ideal case

A normal video camera is not so hard, let's go n.aus of max 4th
Get normal tension springs from the obi. With a few easy steps you can take the tension of the spring synonymous variable. Dear rough estimate and improve afterwards, rumrechnen than long ones.
S.end important is that in the normal position with Camera and especially off, the joint position is roughly horizontal, thus making the half-way, would they want to completely press down until it stops.
But as I said, it is advisable that you make the spring tension adjustment, because the change Umstäde but often, especially since the springs can wear out eventually feel kleinwenig.
It is important that the joints clean with WD-run and are well lubricated 40th Due to the strong pressure to the inside when there are two Federaperate, faulty designs wear out very quickly. Because the weight of the camera so not only pushes the arm down, but the weight still synonymous expressed obliquely inwards, at least in the first spring section. Therefore, the entire rubs tilted slightly with every movement. Deshalt should be the sleeves and the elements (bolts parts) made of steel, otherwise you did not enjoy it long.
What is synonymous requires great attention to the centering / balancing of the camera itself
One should take the trouble to make a front / rear / left / right adjustable fixing plate to make up for the camera too.
Optimally, the camera would turn off in any direction, synonymous if they can swing man of any position of the horizontal to the vertical. It should be as balanced in the center. :-)

Antwort von DaMatt:
Garrett Brown had not synonymous 4kg off-camera.
Also, I assume, as I could see the thread here, wants to spend this much time None. If I make the effort to calculate every detail, then you can use synonymous for each joint bearings. The name synonymous not include Garret chases me afraid, because the steadicam training videos from his branch had seen me.
We needed at least no formula. Me enough pictures of homemade cams to understand what is important.
Furthermore, I finished and works perfectly. And it is not some shit that I built with my colleagues.
I can not synonymous like to offer a demo video to download, if needed.

The post was just of me,
Unfortunately I was not logged.
Again,
I do not deny that you did not need any formulas, but you need not necessarily what to build for your mini-DV Cam something decent in a relatively timely manner.
Respect s.Garret Brown for the invention:-D
Antwort von djoesch:
So let's ask!
What do you think it would bring you some strength-variables for the springs to be calculated?
I can tell you what it takes times:
The more severe the entire structure, which rests on the feathers, the better the exploit works of inertia. The decisive factor is that the springs are strong enough to hold the weight and thus the position of the arm.
The properties of physics in nature can, of course wonderfully with refuting formulas that bring you nothing but the construction.
If the joints work properly oiled-and fulfill their purpose the feathers, alone of all the works: The spring tension, you go up, relax the springs, you go down, this is simply that we need not calculate. Is the camera in Mitellpunkt are synonymous, the lateral movement under control, both because of inertia and gravitation. What nurnoch added, just all the harder, the better it works - because "even lazy" :-)
What will it take calculate the forces?
It is wonderful when the springs the arm up and turn the camera / monitor / Battery-construction press down the arm about half way. Then the whole has fulfilled its purpose.
Checked? ;-)

Hi, find it a bit sad that there is not next on the page and go above all that funktinieren the links with the plans and pictures of the no-longer. The system was definitely the best product in terms of self-built camera. So I fänd's nice if you could provide links to the current building plans again, I would like it as synonymous trying to build an ingenious part!
Thy,
John
Antwort von fast-l:
Hello everybody, I am synonymous s.den plans and relevant, viable, interesting links. Unfortunately, none of this is more active, which I very much regret. Perhaps logs Daniel yes again.
