Abstract

A remapping space may define correspondence between times within a video and times within a time-remapped video. Responsive to user selection of a moment within the video for initiation of time remapping using a selected playback speed, a start point and an end point may be inserted at the selected moment within the remapping space. Responsive to user selection of a segment within the video to apply the selected playback speed in the time remapping, the start point and/or the end point may be moved to change the correspondence between times within the video and times within the time-remapped video.

First claim

What is claimed is:

1 . A system for manipulating time remapping of a video, the system comprising:
one or more physical processors configured by machine-readable instructions to:
obtain video information defining a video, the video including video content having a progress length;
determine user selection of a target moment within the progress length of the video content for initiation of the time remapping, wherein the time remapping is to be performed using a selected playback speed, the time remapping resulting in correspondence between times within the progress length of the video content and times within time-remapped progress length of the video content;
determine user selection of a target segment within the progress length of the video content for application of the selected playback speed in the time remapping;
determine positions of a start point and an end point within a remapping space based on the user selection of the target moment and the user selection of the target segment, the remapping space defining the correspondence between the times within the progress length of the video content and the times within the time-remapped progress length of the video content, wherein changes in the positions of the start point and the end point within the remapping space changes the correspondence between the times within the progress length of the video content and the times within the time-remapped progress length of the video content; and
generate a time-remapped video based on the correspondence between the times within the progress length of the video content and the times within the time-remapped progress length of the video content.

2 . The system of claim 1 , wherein the user selection of the target segment within the progress length of the video content for the application of the selected playback speed in the time remapping is determined based on user interaction with a timeline element of a graphical user interface, the timeline element including a timeline representation of the progress length of the video content, wherein the user interaction with the timeline element includes movement of the timeline representation within the timeline element.

3 . The system of claim 2 , wherein the movement of the timeline representation within the timeline element changes a distance between the start point and the end point within the remapping space.

4 . The system of claim 2 , wherein the movement of the timeline representation within the timeline element corresponds to movement through the progress length of the video content at a constant scale regardless of the progress length of the video content.

5 . The system of claim 1 , wherein a slope between the start point and the end point within the remapping space corresponds to the selected playback speed.

6 . The system of claim 1 , wherein the one or more physical processors are further configured by the machine-readable instructions to determine user selection of a playback direction for the time remapping.

7 . The system of claim 6 , wherein the user selection of the playback direction for the time remapping is made with user selection of the selected playback speed

8 . The system of claim 6 , wherein the user selection of the playback direction for the time remapping is made separately from user selection of the selected playback speed.

9 . The system of claim 6 , wherein the user selection of the playback direction or the user selection of the selected playback speed includes user selection of a video frame for duplication in the time remapping.

10 . The system of claim 1 , wherein the positions of the start point and the end point within the remapping space define a shape of a remapping graph, and smoothing is applied to the remapping graph.

11 . A method for manipulating time remapping of a video, the method performed by a computing system including one or more processors, the method comprising:
obtaining, by the computing system, video information defining a video, the video including video content having a progress length; determining, by the computing system, user selection of a target moment within the progress length of the video content for initiation of the time remapping, wherein the time remapping is to be performed using a selected playback speed, the time remapping resulting in correspondence between times within the progress length of the video content and times within time-remapped progress length of the video content; determining, by the computing system, user selection of a target segment within the progress length of the video content for application of the selected playback speed in the time remapping; determining, by the computing system, positions of a start point and an end point within a remapping space based on the user selection of the target moment and the user selection of the target segment, the remapping space defining the correspondence between the times within the progress length of the video content and the times within the time-remapped progress length of the video content, wherein changes in the positions of the start point and the end point within the remapping space changes the correspondence between the times within the progress length of the video content and the times within the time-remapped progress length of the video content; and generating, by the computing system, a time-remapped video based on the correspondence between the times within the progress length of the video content and the times within the time-remapped progress length of the video content.

12 . The method of claim 11 , wherein the user selection of the target segment within the progress length of the video content for the application of the selected playback speed in the time remapping is determined based on user interaction with a timeline element of a graphical user interface, the timeline element including a timeline representation of the progress length of the video content, wherein the user interaction with the timeline element includes movement of the timeline representation within the timeline element.

13 . The method of claim 12 , wherein the movement of the timeline representation within the timeline element changes a distance between the start point and the end point within the remapping space.

14 . The method of claim 12 , wherein the movement of the timeline representation within the timeline element corresponds to movement through the progress length of the video content at a constant scale regardless of the progress length of the video content.

15 . The method of claim 11 , wherein a slope between the start point and the end point within the remapping space corresponds to the selected playback speed.

16 . The method of claim 11 , further comprising determining, by the computing system, user selection of a playback direction for the time remapping.

17 . The method of claim 16 , wherein the user selection of the playback direction for the time remapping is made with user selection of the selected playback speed

18 . The method of claim 16 , wherein the user selection of the playback direction for the time remapping is made separately from user selection of the selected playback speed.

19 . The method of claim 16 , wherein the user selection of the playback direction or the user selection of the selected playback speed includes user selection of a video frame for duplication in the time remapping.

20 . The method of claim 11 , wherein the positions of the start point and the end point within the remappi
