Abstract
Positions of an image capture device may be used to estimate a time-lapse video frame rate with which time-lapse video frames are generated. The time-lapse video frame rate may be adjusted based on apparent motion between pairs of generated time-lapse video frames. The adjusted time-lapse video frame rate may be used to generate additional time-lapse video frames.
Claims20
A system for generating time-lapse videos, the system comprising:
- one or more physical processors configured by machine-readable instructions to:
- obtain visual information, the visual information defining visual content captured by an image capture device;
- obtain position information of the image capture device, the position information characterizing positions of the image capture device during the capture of the visual content;
- determine periodic motion of the image capture device based on the position information of the image capture device;
- obtain apparent motion information, the apparent motion information characterizing apparent motion between the visual content captured by the image capture device at different moments;
- determine a dynamic time-lapse video frame rate based on the periodic motion of the image capture device and the apparent motion between the visual content captured by the image capture device at different moments, the dynamic time-lapse video frame rate defining a rate at which time-lapse video frames are generated based on the visual content, wherein a value of the dynamic time-lapse video frame rate changes based on changes in the periodic motion of the image capture device and/or changes in the apparent motion between the visual content captured by the image capture device at different moments;
- and
- generate the time-lapse video frames based on the dynamic time-lapse video frame rate, wherein inclusion of the time-lapse video frames, generated based on the dynamic time-lapse video frame rate with a changing value, in a time-lapse video results in the time-lapse video including different portions with different perceived playback speeds.
A method for generating time-lapse videos, the method performed by a computing system including one or more processors, the method comprising:
- obtaining, by the computing system, visual information, the visual information defining visual content captured by an image capture device;
- obtaining, by the computing system, position information of the image capture device, the position information characterizing positions of the image capture device during the capture of the visual content;
- determining, by the computing system, periodic motion of the image capture device based on the position information of the image capture device;
- obtaining, by the computing system, apparent motion information, the apparent motion information characterizing apparent motion between the visual content captured by the image capture device at different moments;
- determining, by the computing system, a dynamic time-lapse video frame rate based on the periodic motion of the image capture device and the apparent motion between the visual content captured by the image capture device at different moments, the dynamic time-lapse video frame rate defining a rate at which time-lapse video frames are generated based on the visual content, wherein a value of the dynamic time-lapse video frame rate changes based on changes in the periodic motion of the image capture device and/or changes in the apparent motion between the visual content captured by the image capture device at different moments;
- and
- generating, by the computing system, the time-lapse video frames based on the dynamic time-lapse video frame rate, wherein inclusion of the time-lapse video frames, generated based on the dynamic time-lapse video frame rate with a changing value, in a time-lapse video results in the time-lapse video including different portions with different perceived playback speeds.
