    From the article:

    For those stuck on dial-up, here is a quick summary of our results:

    * Both "handheld" shots were very shaky with the electronic stabilization performing only marginally better.
    * The "steadicam only" shot was a significant improvement over either "handheld" shot.
    * Turning on the electronic stabilization made the "steadicam" shot even smoother.

    Despite all of this, we found that there was still a little bit of shake in the picture. We expect that a little practice with the steadicam could have vastly improved our shooting technique. All in all, we would say that this project was a big success!

    I saw the video. It was a little better, but the combination of the two made it much better. Unfortunately, it's still far too shaky to consider it useful for any indie film that doesn't want to be branded with the Blair Witch style. So why would you go to the trouble?

        I would add that most of these $15 'steadicams' are equivalent to many of the low-end steadicams that normally don't sell for that much money. The really high-end stuff (e.g. for helicopters) involves gyros to maintain stability against the natural tendency to vibrate, while still allowing gradual motion.

        One could easily add some small gyros to a handheld steadicam design and still come out fairly inexpensive. Take three 6v electric motors and a 6v battery. Add a wheel on the end of each motor, and mount them so that the wheels spin in three planes. Add weights to the wheels to balance them. Continue adding weights until you have enough stabilization. Place this apparatus in a padded box to keep it quiet, and mount the box.

          Since all you really need to dampen is movement along the pitch and roll axes, a single gyroscope with the axis mounted vertically would be adequate. And rather than trying to build and balance your own, you'd do well to save yourself the headache and pick up a nice surplus military missile guidance gyroscope, like this [deutscheoptik.com]. Knock that spinner out of its gimbals and I bet it'd be just right...

        This is probably key - professional steadicam operators are trained specifically in how to operate a steadicam (they're not just camera operators who decide to strap on a rig one day for kicks). If you've ever seen any behind-the-scenes footage of steadicam shots being filmed, it's pretty amazing how smoothly these guys move.

        A lot of amateur camera operators - be it still or motion picture cameras - think good camera work is almost entirely dependent on the equipment. In fact, I'd say way more than half of what it takes to get good results lies with the operator. You can't put together a steadicam rig and then walk down the street like you'd walk normally and expect a steady shot - that won't work even with a real steadicam. You need to walk as smoothly as possible and make smooth, even camera movements. It doesn't look like that was done here, although to Ars' credit, they do note that they probably could have gotten better results with a bit of practice.

        I do think that a rig like this could be a pretty decent option for indie videographers willing to actually learn and practice the proper techniques.

          Thanks for giving me the opportunity to say: This is not even wrong. (I like saying that.)

          Professional steadicam operators use equipment that is completely different from consumer/prosumer 'steadicam'-ish gear. They come in teams of two: The one carrying the rig isn't able to look through a viewfinder, so a second person has to control focus, aperture etc. The apparatus has so much inertia that the carrier can actually hop up and down and the camera will still hardly move, let alone rotate. Lots of practice is only half of the story: the huge weight strapped to the body kind of forces the operator to move smoothly, anything else would be totally exhausting.

          Equipment in the two figure dollar range, on the other hand, isn't more than a handheld tripod that keeps the centre of gravity around your hands by introducing a counter-weight that roughly equals the weight of your camera. With consumer cameras becoming ever smaller and lighter, that isn't much. Jerks introduced by shaky hands are pretty much all they can compensate for somewhat adequately.

          However, this isn't what ars technica actually tested: They walked down a street. The picture resulting from this has to be shaky hand cam style. The "little bit of shake" that the reviewer attested is actually insanely wild. If you haven't got a more expensive steadicam setup, you really only have these two options: Either purposely go for the blair witch style, or let only the actor walk (when shown in the picture, as opposed to the 1st person view) and put the camra person plus camera on some sort of wheeled vehicle, like a dolly with a tripod.

          It seems like the ars techinca reviewers had too much fun doing their oh-so-cool project; not only were they too enthusiastic about the marginal improvement in image quality, they also didn't really factor in the problems they had (they needed much longer than the make mag instructions projected and ran into issues the instructions didn't even touch on) when writing the concluding summary.

          Not that there's anything bad about this: With a USD 14 handheld tripod, you're supposed to have fun, not emulate Oscar-league steadicam gear. And yes you can train to move super-smooth, but still steadicam and steady camcorder are two entirely different issues.

      I'll offer up an answer, since I wrote the review.

      I realized today that there was a small problem with our video test: we weren't following any subject. Most steadicam shots are either following a subject or moving around a subject within a few feet of the camera. As you saw in the test, there was no subject. Consequently, even the tiniest movements seemed to make the whole world shake.

      The other half (as I mentioned in the review) was that we didn't practice much with the steadicam. I imagine with a little work, we could have gotten a really nice shot. One of the areas that could have used some practice was paying attention to how the side bar is held (since it controls the side-to-side motion). You'll see in the last shot that overall it is very smooth, except that there is a little side to side movement.

      All in all, the $14 steadicam was a fun build and worthwhile if you don't have a few thousands dollars for a real steadicam.

      http://www-2.cs.cmu.edu/~johnny/steadyca m/
      It has testimonies of pro's who have used this hand made rig and a $800 steadicam rig, and they say both are great. What you get with the $800 right is a full body vest mount that allows you to mount the camera on your hip, for even smoother shots.

      As someone who has used a steadicam professional rig, i can say that with image stabilization on, the image actually produces strange movement, once you learn how to use the steadicam.

      You can't just pickup a camera attached to a steadicam and notice an amazing difference unless you have learned how to carry your body with the camera. What the steadicam does is make it a lot easier to do so (first your arm is extended at a lot lower angle than holding the camera in your hand and second, the added weight lessens shakes cause by your body).

      If you have ever seen someone use a steadicam, they walk more like a dancer than a doofus with a handicam.

      So to answer you question, after you train to use the steadicam (and have degeeked your forearm strength to be able to hold it for 45 minutes or so at a stretch without tiring) you can achieve shots that would have cost you $800 before, now for only $14. the remaining $786 could be spent on a 3ccd panasonic camera. Or saved for a dvx100 or a wireless mic set, etc.

      It's just a little Physics, not magic: from Johnny Chung Lee [cmu.edu]'s website (and also in the magazine):

      How you use it is 80% of the smoothness. This even is true for the professional stuff with all the fancy shocks and hydraulics. Don't expect this thing to perform miracles, you have to practice using your arms and body to create a smooth motion. Watch your hands while you walk, and see how level you can keep them relative to the ground. Watching the shadow of your hands on a sunny say is an easy way to isolate thier movement. Keep your legs bent and learn how to "glide". I talked with someone who has used professional steady-cams and they said this was, "really, just as good." Getting good results is not so much about the equipment, but how you use it. That's really true about everything.

    How many of you are going to build this? Maybe for fun, but imagine taking one of those along on a vacation or a trip or something. I don't think so. I realize that that is besides the point, but shouldn't some of these projects actually appeal to more tech people, as opposed to a tiny portion who produce movies and such? Recall the Popular Science and Popular Mechanics stuff from teh 60s and 70s: they *had* a purpose and appealed to a much larger audience. Why is it difficult to do the same while keeping the techie edge?

      Well, if I decided to make an indie movie, I'd give it a go.

      "Why is it difficult to do the same while keeping the techie edge?"

      What's wrong with somebody cheaply solving a problem and publishing it? Should they hoard the knowledge or share it? That's the neat thing about the internet: publishing is cheap.
    • I'm going to build one. I'm shooting footage for a documentary, purely for my own interest, using a borrowed camera, and I'd like to steady some shots a bit. I think that there are a fair number of people out there doing things a notch or two above vacation shots, with no thought of financial return, who could use a simple device like this.

    I was kind of relieved to see that the reviewed Make article [makezine.com] was written by the author of the original $14 Steadycam site [cmu.edu], Johnny Chung Lee. The man's a hack, and I mean that in the most endearing way.

    Not to review a review of an instruction, but I think Ars Technica is being a little hard on the Chung. Operating a steadycam is a bit of an artform unto itself.

    A steadycam will not turn Shakes the Clown into the next Scorsese, but once you learn the limitations of the axes you'll get results like Mr. Lee posts as samples on his site (see the bottom of the page, under "Using Your Steadycam").

    I appreciate the effort, but a test video with no subject to focus attention on doesn't really show off how well any of the four tests are working. All I see are tarred cracks in the pavement jiggling in all four.

    Whereas, had they walked with someone down the street, it would have shown off the differences quite well.

    Looking at the design I'd have to opine that while the galvanized steel pipe may be nice and rigid it's really heavy and adds a lot to the weight you'd need to carry. I'd recommend spending $20-30 on a cheap camera monopod and using that instead of the vertical pipe piece. It's much lighter weight aluminum, and you'll already have a camera mount on top saving you a lot of effort and trouble.

    • I agree with this, but not sure if we share the same reason. If you use steel, you add weight above the handel that is not needed, using PVC pipe would be light, and you would not need as much counter weight on the bottom. You could use the same amount of weight, and get more stability if you have less weight on top of the piviot points.
      • Small-diameter PVC pipe is pretty flexible, and with larger stuff it'd get awkward and you'd lose some of the weight savings. The extruded aluminum tubing used in a monopod is both rigid and lightweight.

    I've built the said $14 steadicam and here are some thoughts: 1) First of all, it wasn't $14. It was more like $25 (without buying weights, they where a waste of money) 2) It takes immense practice to use it very well. 3) The sidearm makes this better than any tripod or monopod 4) The rotations are the most impressive part of it. The shots generated are really smooth. If someone will generously provide me with hosting, I can post a compilation of shots I did using the cheap steadicam.
