Systems and techniques for modifying a subsection of uploaded media are presented. An instruction component receives a media file and a media enhancement instruction that includes enhancement data and media interval data for a first segment of the media file. A processing component modifies the first segment of the media file associated with the media interval data based on the enhancement data to generate an edited first segment of the media file. A finalization component generates an edited version of the media file that includes the edited first segment of the media file and at least a second segment of the media file that is not modified based on the enhancement data.
