Just a quick video test with a crane my friend built for me.

Pretty cool.
Does it make much noise when you are moving about quickly?
You using any kind of bearings?

Damn, you have some good friends, I wish I had a friend that would take the time to build me a jib.
Footage looks awesome!
have you tried it with your dof attatched ?

Were those hanging counter weights off the back of the arm?
I can see from the footage that it makes the whole thing wobble just a bit after you move with some rotational motion.
wanna know why i notice this?
i did the same thing with divers weights...
I use a 10 lbs weight to bolt right onto the back now...
good lookin' rig though!

Nice work. You have schematics or a budget for the materials your friend used?
That doesn't look like aluminum or wood to me, and they're the cheapest resources I can think of.
I really appreciate the range of shots you have included here, including the one where the jib isn't moved fast enough to get the actor, then the actor-less jib test, then the money shot where you get him running around the house.
You can really see how difficult a rig like this is to operate with the multiple shots.
Shadow2 also gets thanks, since it only makes sense that the mounted weights would provide for more stability.
I didn't attribute the movement to the hanging weights, but rather operateor hand movement.
I think mounted weights would do better.
One question I have is, how does one change the camera angle while shooting?
I'm thinking, a pair of cables vertically on a pulley and a pair of cables horizontally on a pulley would allow for camera control for a number of different shots.
There doesn't seem to be any cable attached to allow for that here, and some of the shots are not centered on the subject because of that.
What are your thoughts?
Quote: : have you tried it with your dof attached ?
Someone please confirm or correct me here, but a DOF adapter wouldn't work on a jib, since the camera and focusing mechanism are inaccessible.

I will corrct you my self, You can use a wide angle lens stopped down and have enough control over it to shoot some great footage.
Plus, you don't have to operate a jib from the back, in fact we usually have someone on the front and another person running the back of the jib for even more control.
And the last thing I will mention is a REMOTE FOLLOW FOCUS, Their becoming more affordable from what I have gathered in the last few days of looking.
So it's very doable to use a dof on a jib, I have personally done it many times.

Thanks. I didn't realize that.
I thought it'd be to difficult to focus given the movement of the jib.
I'd love to see some footage if you care to share.

This is my setup for shooting off the jib, We have it maxed out as far as weight goes, but it's pretty smooth.
Adding it to the dolly opens new doors as well.
Any ways, I do have some footage that i can dig up and show you.
But overall it's very doable.
Is what we were shooting was a guy that pulls in to a parking space, then gets out of the car,( hits his mark), then walks in to A Panera Bread.
We started low and moved the jib in a upwards vert movement, ( starting as he stepped out with his shoes, then slowly moved up his body, He's a very good actor and knows how to hit his mark usually and knows not to drift while on his mark, this makes it very easy for a focus puller to keep a crisp image.
Then he walked off , losing focus as he left the frame, Then we picked him back up at the door AS he walked towards the cam, as he hit focus, we dollied away to keep him crisp, then blah, blah blah, you get the point, I will try to dig up the entire sequence thats cut together for you to see how easy it really is if you have a good crew that knows what their doing.
Oh, and if you look closely, you can see both jib operators have their own monitor, and the focus puller usually has his own too, depending on the set up, then of course the director (me) has his too.

Good Day Gentlemen,
I built the crane shown in the 1st video above.
I thought that I would register and answer some of your questions.
The crane above is made of wood and aluminum.
The crane arm is a 8' 1x3" pine board painted black.
The upper spar is a 8' long 3/4" aluminum "c" channel.
The base is made from 2x4's and features a 6" turntable bearing.
The tripod is a 1-3/8" diameter speaker stand.
The base mounts to the speaker stand thanks to a section of 1-1/4" Dia.
PVC pipe and a flange mount.
(See 0:13-0:20 in the video)
The house in the background was built in the 20's and the weight came from some windows I replaced.
We will be replacing them with round weights (not tethered).
This crane was build out of scrap materials I had in the garage with the exception of the turntable bearing.
The crane arm is purposely made from two pieces of wood so that it can collapse and store in my truck for transportation.
The crane creates no self noise.
The crane arms rotates on 3/8 bolts with two fender washers (no bearings).
With the right tension and a little lithium grease these will be as silent as bearings.
I took this design from a indy mogul video for a 25$ mini jib.
Having successfully created our first crane we are brain storming mods and improvements.
Next I want to work on a car mounted rig.

Clarky, your crane is great, where did you find the steel tube that slides in to each other?
|

I just went to a local steel shop and they cut it to lenght for me.
Its 2" to 1.5" to 1" tubing.
Its not a perfect fit, but if you drill the holes right, it is very strong.
I am sure if you looked into it more, you could find steel that fits perfectly, I was just in a bit of hurry as we had a shoot coming up!
Thanks for the positve comments about the crane.
