Great idea. I can imagine turning this "ad-hoc" trick into a standalone app which can visually detect flicker similar to an in-camera test. Coupled it with @aapo lettinen's waveform-view suggestion and @Robin R Probyn's FLICKERfree calculator, would it be worth a digital download on the app/android store for what, $100? I've pitched this to my programmer friend and he's started work on it on his downtime. Anyone interested to keep in touch about this?
Hi Yann, which of these do you prefer and which features do you mainly use? I'm interested in picking one up, which do you suggest?
I've rented expensive Phantoms before, only to discover nearly every single light on set flickers when shooting at higher than 120fps, delaying the production. It's not always available for a test shot when it's actually convenient to check. But nothing can substitute an in camera test, yeah... unless you playback in real time which might sync with the problematic light 🙂
Thoughts about creating an app?
