Systems and methods for improved content item delivery and output

A system comprising a computing device having:

• input/output circuitry configured to:
• receive a content item comprising at least a plurality of portions;
• and
• control circuitry configured to:
• generate at least one of the plurality of portions in a first size and a first resolution;
• determine that a first complexity score associated with the plurality of portions is below a threshold complexity score;
• determine that a length of the plurality of portions is above a threshold length;
• and
• based on determining that the first complexity score is below the threshold complexity score and that the length of the plurality of portions is above the threshold, generate, for simultaneous output, (a) a portion of the plurality of portions of the content item in a second size and a second resolution and (b) a supplemental content item in a third size and a third resolution, wherein:
• the third size is greater than the second size;
• the second size is greater than the first size according to a proportion;
• the second resolution is based on the proportion;
• and
• the supplemental content item is distinct from the content item.
