Claim 8:
9. The video sound-picture matching method according to claim 8, wherein
determining the active segment comprises:
determining a minimum value of a second reverse duration according to the initial position of the start-stop mark and the start frame of the pth active segment, wherein the minimum value of the second reverse duration is greater than the minimum value of the first reverse duration;
determining a first reverse duration interval according to the minimum value of the first reverse duration and the minimum value of the second reverse duration; and
scaling, in response to determining that the voice segment is within the first reverse duration interval, a duration between the start frame of the pth active segment and the initial position of the start-stop mark according to a duration of the voice segment to obtain the active segment; and

the updating the initial position of the start-stop mark in response to determining that a condition for updating the position of the start-stop mark is met comprises:
meeting the condition for updating the position of the start-stop mark in response to determining that the voice segment is within the first reverse duration interval; and
updating the initial position of the start-stop mark to a position corresponding to the start frame of the pth active segment.
