    Hello HN! Over the last 15 years, I’ve worked as an AE/Editor, DIT, Colorist, Online Editor & Post Supervisor and based on my experience I've built a tool that I hope will be useful for some of you! It's a cinema calculator (aspect ratios, target speeds, target bitrates & more...) called CineMath and it's available for free download in the Apple App Store.
