I want to test a camera that I may buy. In the long run I hope to apply post-effects (composited elements, rotoscoping, etc.) to the footage, so I'm concerned about image steadiness. I've read here that the Arri S should produce solid footage, and I know the basics about shooting an image steadiness test: solid mount, sharp image of a test chart / lines, shoot twice underexposing one stop each time. But I don't know the important stuff - how to evaluate the results. So here are some questions. What's the best way to view the test results? Transferred to video? And do I need to be careful to use or avoid a certain type of transfer to make sure that it isn't influencing the results? Is there a way to quantify any "unsteadiness"? Like, is there a protocol for shooting a chart with an exact line spacing? Are there different kinds of "unsteadiness", and if so, are they indicators of different kinds of camera issues? Lots of questions - if you have answers or know of another source of info I'd appreciate it.
