Abstract: Techniques are provided for aggregating data about multiple user interactions with a media (video or audio) item and analyzing the aggregated data. Based on the analysis, a recommendation and/or a report may be generated. Alternatively, one or more changes are automatically made to the media item. A recommendation indicates how the media item may be improved. The recommendation may indicate where the media item should be modified. The recommendation is then provided to a creator of the media item. A report indicates where within the media item different user interactions are occurring. If a change is automatically made to a media item, then a report may be generated that indicates a difference between user interactions before the change and after the change.

Abstract: Techniques are provided for associating comments with certain positions within a video (or audio) timeline. Multiple users compose comments, such as questions, and cause those comments to be stored in association with the video. Each comment is stored in association with a specific point or section in the video timeline. Later, another user can view the comments and select a particular comment, which causes the video to be played at the position in the timeline associated with the particular comment. Additionally or alternatively, playing a particular portion of a video may cause one or more comments that are associated with the particular portion to be displayed.

Abstract: Techniques are provided for creating annotations of user input. In one technique, user input is received on a screen while a video is being played. The user input corresponds to a period of time that includes a first time and a second time. While the user input is received, a first snapshot is generated of the user input and a second snapshot is generated for the user input. The first snapshot corresponds to the first time and the second snapshot corresponds to the second time. A first annotation that identifies the first time is created based on the first snapshot. A second annotation that identifies the second time is created based on the second snapshot. Each snapshot is stored in association with the video.
