These numbers are not absolute,
however. There are many factors that could change the final output resolution. The second rows under some of the formats represent
alternate resolutions asked for by some postproduction facilities. Some facilities may also ask for rendered output resolutions not on this
chart. It all depends on the particular needs of the project.
