Retiming in a Video Sequence

摘要

Slow motion is added to a video clip using retiming. Retiming adjusts the timing of the video. The video sequence may be stored ahead of time, modified in real time as the video is collected, or in real time as the video is played back. A memory stores a video sequence. A processor selects a subset of frames from the video sequence based on a focus frame identifier and a slow motion timing pattern. The processor generates at least one intermediate frame for insertion into the subset of frames based on the slow motion timing pattern for the video sequence and the focus frame identifier for the video sequence.

1. A method comprising:
receiving a video sequence; selecting a retiming code for the video sequence; accessing a focus frame identifier; selecting a subset of frames from the video sequence based on the focus frame identifier and the retiming code; interpolating at least one intermediate frame using at least one motion vector defined by the subset of frames; and inserting the at least one intermediate frame into the subset of frames.
