In this embodiment, a switching node may be added based on an input position of the first input on the first video progress bar, and the switching node is referred to as a first node. And determining the time characterized by the first node as the starting time of the target time period.
After the first node is determined, a second node is determined according to a position of the first node on the progress bar, specifically, a node adjacent to and behind the first node on the progress bar is determined as the second node, where the second node is any one of an end node and at least one handover node. And determining the time represented by the second node as the end time of the target time period.
After the first node and the second node are obtained, a time period between the first node and the second node is determined as a target time period.

In this case, since the third handover node is adjacent to the first node and is located behind the first node, the third handover node is determined as the second node, and thus the time period from the first node to the third handover node is determined as the target time period.
In the following, how to determine the first node based on the input position of the first input on the first video progress bar is specifically described:
optionally, the determining a first node based on an input position of the first input on the first video progress bar includes:

The pointing object of the fourth input is a third node, and the fourth input includes, but is not limited to, a slide input, a touch input, a press input, or other types of inputs.
It should be understood that the target position is located between the second node and a fourth node, wherein the fourth node is adjacent to the third node, the fourth node is located before the third node, and the fourth node is any one of the start node and the at least one handover node. The definition of the second node is the same as that described in the above embodiments, and will not be repeated here.
For example, the progress bar includes 4 switching nodes, and the time node pointed by the first input is set between the second switching node and the third switching node in order from left to right, and then the time node pointed by the first input is determined as the third node, resulting in the application scenario shown in fig. 5, where 51 in fig. 5 is used to identify the third node, 52 in fig. 5 is used to identify the second switching node, and 53 in fig. 5 is used to identify the third switching node. In this case, since the second switching node is located before and adjacent to the third node, the second switching node may be determined as the fourth node; since the third switching node is located after and adjacent to the third node, the third switching node may be determined as the second node. Optionally, the user may perform a leftward sliding operation or a rightward sliding operation on the third node, move the third node, and determine the moved third node as the first node, where the first node is located between the second node and the fourth node.
In other embodiments, the user may further perform a sliding operation on the switching node on the progress bar, and adjust the switching time of the preview picture corresponding to the switching node, so as to adjust the duration of the shooting picture of each machine position.
