ken koller Posted February 21, 2012 Share Posted February 21, 2012 I am looking for a method of circling my talent at high speeds in combination with high speed photography. I have already looked into Pacific Motion Control's Cheetah dolly and it's speed is too slow for my purposes. Any ideas? Thank you. -Ken- Link to comment Share on other sites More sharing options...
Premium Member Chris Keth Posted February 23, 2012 Premium Member Share Posted February 23, 2012 How many revolutions per minute or per second are you interested in being able to do? Link to comment Share on other sites More sharing options...
Chris Millar Posted February 24, 2012 Share Posted February 24, 2012 At my previous job we part built a dolly track with cambered rails about 6m in diameter. Idea was to only have 180deg of curve - straight run in for speed up and then simply coast (at a great rate of knots) around the 180deg then straight again for slow down. Yes the cambers made going from straight to curved 'interesting' - there was a plan around it... ;) 360deg of arbitrary revolutions is what you're after ? What diameter ? Do you want it motion controlled ? How heavy a camera ? Thought about bullet time ? Link to comment Share on other sites More sharing options...
Premium Member Dom Jaeger Posted February 24, 2012 Premium Member Share Posted February 24, 2012 For really high speed circling maybe it would be easier (and safer) to spin the talent and green screen the background? Link to comment Share on other sites More sharing options...
Chris Millar Posted February 24, 2012 Share Posted February 24, 2012 You wont have the rig in shot that way either - although, safer ? Link to comment Share on other sites More sharing options...
ken koller Posted February 24, 2012 Author Share Posted February 24, 2012 To answer your questions. I'm not sure on the exact revolutions per minute I'm looking for, but I'm visualizing using a phantom for some really high speed stuff and Red Epic for the rest. So when in use with the phantom the revolutions are going to need to be quick enough to make the effect play. Chris, the curve sounds good for one pass, but I would like to get multiple revolutions. I would prefer not to spin talent as it will effect wardrobe and props. Link to comment Share on other sites More sharing options...

Ken, So when in use with the phantom the revolutions are going to need to be quick enough to make the effect play. ...best to do some timings of your shot, plan it out Link to comment Share on other sites More sharing options...
ken koller Posted February 26, 2012 Author Share Posted February 26, 2012 Thank you for all the replies. There are multiple shots however the speed ring at this point is looking like the best bet. Link to comment Share on other sites More sharing options...
