Hi Kes:

 

Is everything Ok.

My littles advices are:

-Buy the EFP Video training tape and see it 100 times. ;)

-After, search a goooood workshop.

You are lucky man!.

You live in USA, and you are close of a majority of Workshop

I´m in Argentina! (like Guillermo Nespolo says, "in the ass of the world")

Best regards,

A quick note about dynamic balance as well - what you see is what you get, i.e., whenever you pan the steadicam, no matter how slow, being out of dynamic balance will cause the camera to deviate from your desired roll and tilt. This causes one more difficulty for every shot that you must deal with, perhaps unconsciously, as you try to maintain a nice horizon and headroom. The inevitable result is more wobbling around with the frame. The faster you pan, the more obvious and horrendous the result. It is easy to see by simply panning the steadicam (mounted on your body, or on the balancing pin of your stand, at various speeds on its own - start a pan and remove your hand. Whatever deviation the sled takes will be in your shots to some extent, especially when you consider that the best looking pans are done without interfering with the inertia of the system once you get it going, but just letting your operating hand go along for the ride until it is time to stop the pan. (This also works best if you don't have to do any tilting during the pan, with the post absolutely vertical, which implies that consistently great pans require a tilt head unless you always arrange to do pans only when the camera is dead level). Any need to control the pan once it is started will result in a less beautiful result. Once you start eliminating the wobbles that occur because of bad dynamic balance you will start to see better results in all your operating. It will be more about your own skill level and less about badly adjusted equipment, and it is hard enough to do good work with a Steadicam even with a perfectly setup rig!

Larry,

 

I recall you saying once that you tend to go more heavy bottom, in that case do you do your static and dynamic balance at that heavy bottom setting or you do dynamic and static balance at 4 seconds or so and than shift your gimbel to get more heavy at the bottom for the operating ? I find it more difficult to achieve dynamic balance at 4 seconds ( I also operating at 4 seconds ) than 2 seconds. Also the fast paning is more difficult so when I do a fast pan I tend to operate at 2.5-3 seconds although I would like to be able to get the same result at 4 seconds, something I would have to work on.

 

Best

Hi Kes

 

You need to do the balance on the rod thing before you attach the dovetail and then contrive to mount the dovetail in such a way as to get the most available adjustment. If the Sony screw holes don't line up try turning the dovetail plate back to front, I have balanced this combo many times and never had a problem, you should not need a longer plate.

Thanks Robin,

 

This is basically what I have start doing - turning the dovetail plate back to front often as the Sony screw holes don't line up beautifully always. Perhaps when CP built the the dovetail plate they did not have the Sony plate on their mind.

 

By the way Robin my brother bought a very good thin Triax cable from you which has been very helpful for me often when doing t.v, he also spoke highly about you... . Dont know where he is now - I have not seen him for 3 months as he travels around beautiful places doing traveling programs. Left his steadicam for me though...

Glad to have been of service but since I only see you as Kes on the forum I don't know who your brother is, maybe you could let me know and satify my frustrated curiosity!

 

By the way with regard to the screw holes, the dovetail plate has imperial hole centres (inches) whereas the Sony plate has metric which is why they don't match. If the spacing is just slightly out for your chosen holes (assuming you are using TWO screws), push the screws through until the unthreaded section it in the hole before you screw them in and the screw in each one a bit at a time. Be careful not to lock them up though.

 

Better still get hold of a Chrosziel quick-lock plate for the Sony which is a much better device than the Sony one and has sliding threaded bosses to screw into.
