9. The system of claim 1 , wherein at least some of the items of digital content are received from the computing device of the user.

10. The system of claim 1 , wherein the individual moment clusters correspond to a period of time, and the individual scene clusters correspond to a sub-period of time.

11. The system of claim 10 , wherein the period of time corresponding to the individual moment clusters is changed based on a number of items of digital content within one or more of the moment clusters.

12. The system of claim 1 , wherein the individual moment clusters correspond to a geographic area, and the individual scene clusters correspond to a sub-geographic area.

13. The system of claim 12 , wherein the geographic area corresponding to the individual moment clusters is changed based on a number of items of digital content within one or more of the moment clusters.

14. The system of claim 1 , wherein a number of items of digital content selected from the individual moment clusters for inclusion in the media presentation is based on sizes of the individual moment clusters.

15. The system of claim 1 , wherein metadata associated with the respective item of digital content includes values for brightness, contrast, blur/sharpness, and/or number of human faces in the respective item of digital content, and the goodness measure for the respective item of digital content is determined based on the values for brightness, contrast, blur/sharpness, and/or number of human faces.

16. The system of claim 15 , wherein the goodness measure for the respective item of digital content is determined based on a weighted average of the values for brightness, contrast, blur/sharpness, and/or number of human faces.

17. The system of claim 1 , wherein the goodness measure for the respective item of digital content is set to a minimum value based on the metadata associated with the respective item of digital content not including any values for brightness, contrast, blur/sharpness, or number of human faces in the respective item of digital content.

18. The system of claim 1 , wherein the respective item of digital content is removed from a respective cluster based on the metadata associated with the respective item of digital content not including any values for brightness, contrast, blur/sharpness, or number of human faces in the respective item of digital content.

19. A computer-implemented method for selecting digital content to be included in a media presentation, the method being executed using one or more processors and comprising:

clustering, by the one or more processors, items of digital content into a hierarchy of clusters, the hierarchy of clusters including moment clusters and scene clusters, individual moment clusters including two or more of the scene clusters, and individual scene clusters including one or more of the items of digital content;

determining, by the one or more processors, a goodness measure for individual items of digital content within the individual scene clusters, the goodness measure indicating a quality of a respective item of digital content;

selecting, by the one or more processors, two or more of the items of digital content for potential inclusion in a media presentation based on a hierarchical process of identifying at least one item of digital content from the individual scene clusters based on the goodness measure and selecting a plurality of the identified items of digital content from the individual moment clusters for potential inclusion in the media presentation, wherein the selected items of digital content include a first item of digital content, a second item of digital content, and a third item of digital content;

identifying, by the one or more processors, redundant digital content from among the selected items of digital content such that the first item of digital content is identified as being redundant of the second item of digital content;

selectively removing, by the one or more processors, an item of redundant digital content from the selected items of digital content for potential inclusion in the media presentation based on the quality of the item of redundant digital content indicated by the respective goodness measure such that the first item of digital content is removed from the selected items of digital content responsive to the respective goodness measure of the first item of digital content not exceeding a threshold goodness measure, and such that the first item of digital content is retained as one of the selected items of digital content responsive to the respective goodness measure of the first item of digital content exceeding the threshold goodness measure, wherein the respective goodness measure of the first item of digital content exceeding the threshold goodness measure indicates that the quality of the first item of digital content is sufficiently high such that that removal of the first item of digital content from potential inclusion in the media presentation is not performed; and

providing, by the one or more processors, the media presentation for display on a computing device of a user, the media presentation comprising at least one of the selected items of digital content.

20. A non-transitory computer readable medium storing instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:

clustering items of digital content into a hierarchy of clusters, the hierarchy of clusters including moment clusters and scene clusters, individual moment clusters including two or more of the scene clusters, and individual scene clusters including one or more of the items of digital content;

determining a goodness measure for individual items of digital content within the individual scene clusters, the goodness measure indicating a quality of a respective item of digital content;
