I'm rendering some large 4k tiff sequences in the evening and I want to check them to make sure there aren't any errors. So I render a separate quicktime that is viewer-friendly so that I can check them. A coworker suggested to me that my quicktime may render fine, but that AE could write bad TIFF frames and I'd never know it. He things to be 100% safe I should first render my TIFF sequence, and then re-render that sequence as a quicktime. What do people think?
