Systems And Methods For Generating A Video Clip and Associated Closed-Captioning Data

摘要

Disclosed herein are systems and methods for generating a video clip and associated closed-captioning (CC) data. An example method involves accessing a first video clip demarcated into frames; accessing CC data demarcated into CC blocks, identifying a starting frame from among the frames; determining a first set of frames that are within a range of the starting frame; determining a first set of CC blocks that correlate to the first set of frames; receiving a selection of a starting position from among the first set of CC blocks; identifying an ending frame among the frames; using the ending frame to identify an ending position; and generating a second video clip and associated CC data, wherein the second video clip includes the frames spanning from the starting frame to the ending frame, and wherein the generated CC data includes the CC blocks spanning from the starting position to the ending position.

1. A method comprising:
accessing a first video clip demarcated into contiguous frames; accessing closed-captioning (CC) data demarcated into contiguous CC blocks, wherein each of the frames correlates to a respective one of the CC blocks according to a common processing time; identifying a starting frame from among the contiguous frames; determining a first set of contiguous frames that are within a range of the identified starting frame; determining a first set of CC blocks that correlate to the determined first set of contiguous frames; providing for presentation the determined first set of CC blocks; receiving a selection of a starting position from among the presented first set of CC blocks; identifying an ending frame among the contiguous frames; using the identified ending frame to identify an ending position from among the accessed CC data; and generating a second video clip and associated CC data, wherein the second video clip includes the frames of the accessed first video clip spanning from the identified starting frame to the identified ending frame, and wherein the generated CC data includes the CC blocks of the accessed CC data spanning from the selected starting position to the identified ending position.
