Detailed Description
The present invention will be described in further detail with reference to examples, which are illustrative of the present invention and are not to be construed as being limited thereto.
Example 1:
a method of dynamic video editing comprising the steps of:
step 1, inputting element nodes and logic nodes, connecting the element nodes and the logic nodes, and generating directed graph data;
step 2, acquiring video elements, and generating video element directed graph data with a video element showing logical relationship by combining the directed graph data;
step 3, calculating the node duration according to the video element directed graph data and the video elements, and generating video element weighted directed graph data containing node display duration;
step 4, calculating time position information and total video duration of each element node according to the video element weighted directed graph data to generate video time axis data;
and 5, synthesizing the final video according to the video time axis data.
The element nodes comprise presentation elements in the video, such as elements required to be presented by the video, such as characters, diagrams, pictures and the like.
The time information contained in the element node data includes: delay time and element presentation duration relative to the last node.
The invention also solves the problem of how to automatically adjust the time position of each video element in a video and automatically generate a final video time axis when facing the video elements with dynamically changing duration.
Specifically, when two nodes are connected, it is indicated that the node connected with the connection starts to be displayed after the display of the node connected with the connection is finished, in addition, the element node is defined to allow only one connection to enter and one connection to exit, and when the time length of the element node is 0, the display time length of the element node is continued until the first logic node of the connection is finished.
The logical nodes are logics for showing how the element nodes are shown, and do not occupy the showing time, and the following logical nodes are disclosed in the example:
A. a start node: the video starting node is a video starting node, one video only has one starting node, one or more connecting lines are connected, and no connecting line is connected;
B. and (4) stopping the node: showing that the video elements connected into the node are shown to be finished, wherein the stopping node is connected with one or more lines and is also a stopping node;
C. condition judging nodes: the node is used for judging whether the element node behind the node is displayed or not, and the node is connected with one or more lines;
D. and (3) circulating the nodes: the cycle nodes comprise a cycle start node and a cycle end node, and are used for circularly showing the node elements in the cycle start node and the cycle end node,
the loop starting node transmits array data, the loop times are array lengths, element contents in the loop nodes are displayed according to different element contents from the data of the current loop, and one or more lines are connected in and out of the loop starting node and the loop ending node.
The above is the logical node disclosed in the present embodiment, and the logical node is not limited to the above nodes and may be expanded as needed.
The connection data is a directional connection between two nodes, each connection data comprises a connection node and a connection node, and the connection node corresponds to an edge defined in the data structure of the directed graph. The start time of each node relative to the video timeline depends on the longest one of the previously connected paths.
Step 1 further describes that the directed graph data includes node data and link data, and the node data includes element nodes and logic nodes, which correspond to vertices in the directed graph data structure. Storing all element nodes and logic nodes into a node array, storing all connecting lines into a node connecting line array, and generating video node directed graph data; the video node directed graph data is stored as a video template. Fig. 2 is an exemplary diagram of the video node directed graph data.
Step 2, further describing, analyzing the directed graph data, traversing the video node directed graph data from a starting node in the node array through connecting line data, and generating associated video element directed graph data according to the logic of the logic node;
during the traversal, the node data in the path before the current node is accessed is traversed preferentially according to the connection sequence.
The traversal process is illustrated in detail by fig. 3:
when the 'big title' of the node is traversed from the start node, and then the 'circulation start' node is traversed downwards according to the connection relation, because the 'date character' node of the node connected before the 'circulation start' node is not traversed, the 'date character' node is traversed firstly, and then the 'circulation start' node is traversed. The 'loop node' in the example has two loops, so after the nodes in the 'loop node' are all traversed, the 'loop start node' is returned, and the nodes in the loop are traversed again until the loop number reaches 2 times. After the loop is cycled for 2 times, the loop is traversed to the 'loop end node', and then the loop is connected to two condition judgment nodes, in the example, the 'condition 1' node is judged to be false, and the 'condition 2' node is judged to be true, so that the content of the node behind the 'condition 1' node is ignored, and only the path behind the 'condition 2' node is traversed. Since two paths are not traversed before the terminating node, nodes in the two paths are preferentially traversed.
Step 3 further describes that after traversal according to the steps shown in fig. 3, video element directed graph data which really needs to be displayed is generated, then each dynamic video element and dynamic contents such as data or voice are assembled, the actual time length of the node is calculated, wherein the time lengths of all logic nodes are 0s and do not occupy the time length, and the time length is added to the video element directed graph data to generate final video element weighted directed graph data, as shown in fig. 4.
Step 4, further describing, according to the video element weighted directed graph data, the time position information and the total video duration, generating video time axis data; the time position information is the time position relative to the whole time axis. Including element node play start time and play duration.
The method specifically comprises the following steps: preferentially traversing the node data in the path before the current node is connected according to the connection sequence, acquiring the path with the longest time in the path before the current element node during the traversal, and recording the path as the play starting time of the current element node;
during the passing, acquiring the time length of the current element node, and recording the time length as the playing time length;
and when traversing to the stopping node, recording the duration of the path with the longest time before the stopping node as the total duration of the video.
The traversal process is shown in fig. 5, the longest duration of the path before the current element node is recorded before the slash above the node in the graph, the actual duration of the current element node is after the slash, the total duration of the video calculated in the graph is 23s, and the start playing time (i.e., the longest duration of the path before the current node) and the playing duration equivalent to the time axis have been calculated by all the element nodes.
And the longest time length of the path before the current element node is the longest time length in the result obtained by adding the longest path time length of the node connected before the current element node to the time length of the node connected before the current element node.
Specifically, for example, if the display duration of the start node before the "headline" is 0, the time before the slash is 0s, and the display duration of the element node "headline" as the current node is 3 s;
the 'cycle start' node is a logic node and does not occupy time, so the time before the slash is the longest time of the front path of the node for 3s, and the time after the slash is 0 s; the calculation mode is analogized in the same way.
It should be noted that the "node" described in embodiment 1 is a generic name of all different types of nodes, and does not refer to any element node or any logic node.

a dynamic video editing system comprises a node editor and a video editor, wherein the node editor is used for editing element nodes and logic nodes to generate directed graph data;
and the video editor is used for calling the digraph data and the video elements, generating video element digraph data, namely video element weighted digraph data, calculating the presentation duration to generate time axis data, and generating a video according to the time axis data.
