should i encode my movie in 4:3 ratio or 16:9 ratio?
4:3 is fullscreen (TV), 16:9 is widescreen. I always use widescreen with possible, goes best with my new TV
It totally depends on what form the source is in. If its 4:3, stay with 4:3 (fullscreen on a normal TV/Monitor) but if its leterboxed in any form, then use 16:9.
