After Effects Classic Course: Standard Definition Pixel Aspect Ratios

Standard definition has a concept of “production” versus “clean” aperture, meaning some pixels included in the signal (and therefore, captured video frame) where never intended to be part of the composition we make visible to our viewers. This video explains this non-intuitive subject, and suggests the best working practices for both broadcast and web delivery. This movie previously appeared as part of a longer course on Lynda.com/LinkedIn Learning. They've retired that course from their library, so we're making the individual movies from it that are still relevant available publicly for free. These videos are usually accompanied by short posts on the Crish Design ProVideo Coalition blog channel: https://www.provideocoalition.com/c-t...
