Tadeusz Kieniewicz Posted October 25, 2009 Share Posted October 25, 2009 Hi there! I was thinking about controling the speed in dolly. Does anyone has an idea how to make the same speed in every shoot? In few weeks i will shot a music video and i'd like to achive the same speed of each doly move. It's quite important cuz i will shot in slomotion about 60fps and wondering is it possible to make every ride similar to each other:) thanks for your time.:) Ted.

Premium Member Hal Smith Posted October 25, 2009 Premium Member Share Posted October 25, 2009 Place marks along the track or floor at regular intervals and then time your total move in seconds. Divide the total time in seconds by the number of segments (not marks) and then run a rehearsal with someone calling out the numbers of the marks at whatever is the seconds per segment is that you got with the division step. If your shooting a music video you're probably not recording live sound but if you are, use a wireless intercom system back to the dolly grip wearing headphones so you don't have to shout out the numbers. Even a relatively inexperienced dolly grip can pace the move and reproduce it reasonably well with marks and a count. But as Tom said: If you've got the budget, hire a pro dolly grip.

Thanks a lot! I probably place marks and give answer how it warks for me. Ted. Link to comment Share on other sites More sharing options...
David Rakoczy Posted October 26, 2009 Share Posted October 26, 2009 A good Dolly Grip won't need to do all that.. (he) will maintain the same speed (as humanly possible)... take after take. Link to comment Share on other sites More sharing options...

I'll second the "get a good dolly grip". I've seen speed things done with little pocket metronomes instead of someone calling out the marks.

Nick Hemphill Posted November 3, 2009 Share Posted November 3, 2009 Have the dolly grip start the push with the heals of their hands and letting then roll on the handle till they are pushing with the center of their palms. After that its all on the person to keep the speed constant. But it is that little beginning that makes all the difference. Link to comment Share on other sites More sharing options...
Premium Member John Sprung Posted November 4, 2009 Premium Member Share Posted November 4, 2009 Since you have a few weeks to prepare, and a student budget, do some practice. Borrow a shopping cart and fill it with something for weight to match the feel of the dolly. Find a place where you can do a fairly long run over and over, and time yourself. Write your times down, and you'll know how accurate you can be. Get some of your fellow students to come along, and make it a game. Winner gets to be dolly grip, loser pays for the pizza.... ;-) The next step up from a good dolly grip is to use a motion control system. They've been around for 30+ years, but are still rather expensive. Back before CGI, they were used to match moves frame accurately for composites. -- J.S.
