Robert Frost once wrote of two roads diverging in a yellow wood, and the Motion Picture Industry seemingly has gone a similar route with two Display Standards diverging in potentially one yellow framing guide.
ratioToRes is a powerful tool that will provide valid resolutions for common or custom aspect ratios and constrain them within the two major delivery aspect ratio containers, DCI and 16x9.
The creation of this tool was inspired by work I've been doing in the Modern Digital Cinema and Streaming Era to assist in guiding that might be destined for theaters or streaming platforms and often both arenas.
This tool will also produce accurate resolution and aspect ratio framing guides by clicking on the cyan resolution links on the results page.
