Hi everyone, I'm looking for testers for a new FlickerFinder App which helps crews spot flicker on set. https://flickerfinder.com Anyone who signs up for early access will get an extra free copy at launch to share. An in-camera test to find flicker isn't ideal since it happens late; if there's a problem it means that the production is delayed. Viewfinders can also mask flicker, especially at high frame rates. Sometimes props can also get mixed up and reintroduce flashlights which have bad PWM flicker. Since the problem is spread between Lighting, Camera, & Art, it's a real PITA, which is why I made the app. Let me know your thoughts: https://flickerfinder.com
Shooting on Cannon 7D, 24 fps, 50th shutter speed. The scene is the subject lit only by a pulsating strobe light. What is the easiest/ most affordable solution to sync the strobe with camera and avoid flicker, banding etc.? If possible, I'd like to have various speeds of the strobe for dramatic build. Any recommendation on brand/type of strobe? Will be using house power. Shoot is in Los Angeles. Thanks!
