Abstract: The present disclosure involves systems, software, and computer implemented methods for automatically modifying values of content elements in frames of a video. One example method includes obtaining an input video. A set of elements included in one or more frames of the input video is identified. Metadata is generated for each element in the set of elements. A determination is made that a value for a particular element in the set of elements is targeted for replacement. A replacement value is determined for the particular element and updated metadata is generated. A metadata entry for the particular element is updated to include the determined replacement value. Output content is generated based on the updated metadata the output content is provided for display.
