Post Continuous movement
Hello everyone.
I would like to know if exists (to buy) a motorized dolly which implements both a continuous and non-continuous movement. A movement of type: move-stop-shot, and again (for night shots).
And also let me know if it is difficult to implement such a system.
Thank you all!

And if I want to build one?
I do not have much experience with electronics, but I have a lot of good will so I might try my hand!
Thank you for your reply.

You can just pick up the MX2 controller: http://dynamicperception.com/index.php? ... ucts_id=27

Or if your really feeling DIY and you have experience soldering: http://dynamicperception.com/index.php? ... ducts_id=9

I didn't know it does continuous motion. How fast is this?

The Dynamic perception dolly is designed for timelapse, so it doesn't go that fast in continuous motion mode. You can get faster turning Dayton gearmotors from Servocity which are plug and play replacements for the one on the dolly. The MX-2 controller is only rated to 1 amp, but I beleive a few people have exceeded that slightly and survived. Servocity also sells an electronic speed controller that works with any of their servo controllers to run DC motors up to several amps. If you are looking to modify the DP dolly for realtime 30 FPS video, you might want to use any of their servo controllers plus the ESC to run the motor instead of the MX-2. Their programmable servo controller will let you do a dolly move manually, wile recording the move. You can then play the move back as many times as you want by just pressing one button. They even have a computer based controller that can coordinate up to eight motors for a multiaxis system.

The DP dolly is not that quiet, since it is for timelapse, that wasn't an issue. The motor rings the aluminum track like a bell every time it moves. For shooting realtime video, It is a lot quieter if you mount the motor to some other support that is not attached to the track, and pull the trolly with it.

Servocity.com for motors, gears, etc.

80/20.com for the track and teflon bearing pads

Dynamicperception.com for dollys, kits, MX-2 controllers

A guy should be able to have a pretty good time with all that stuff.

anyone have any examples of video shot on continous motion? i realize it's slow to be used for video work in real time but for what i will be doing it will work ok since i will be speeding the video up anyway so as long as it's smooth it will work for me. i wont be using on board audio either.
