Currently, a video editing tool, such as a format factory, MediaCoder, and other software, can be used to intercept data of a specified time period and store the data as a clip through a series of steps of parsing, decoding, resampling, encoding, packaging, and the like. However, the above editing method is only suitable for files to be edited in a specific format and in a specific time period, and it is difficult to edit mixed files to be edited on a timeline; and when the editing tool is used, various parameters need to be configured, and the file to be edited is difficult to be edited arbitrarily.
Based on the technical scheme, the time scales of the files to be edited on the time line are determined, and the files to be edited are visually edited to obtain the target file, so that the files to be edited in the mixed format can be arbitrarily edited on the time line without configuring parameters.
In accordance with an embodiment of the present invention, there is provided an embodiment of a timeline-based editing method, it being noted that the steps illustrated in the flowchart of the drawings may be performed in a computer system such as a set of computer-executable instructions and that, although a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than here.
In this embodiment, a timeline-based editing method is provided, which can be used in electronic devices, such as a mobile phone, a tablet computer, a computer, and the like, and fig. 1 is a flowchart of the timeline-based editing method according to an embodiment of the present invention, as shown in fig. 1, the flowchart includes the following steps:
and S11, acquiring at least one file to be edited.

For example, when the electronic device determines that the file to be edited is a text file in a TXT format, a time stream of the text file may be generated through self-establishing time, a memory stream of the file is read and converted into an object stream with an attribute, and a time attribute is given to the object stream, so that the text file may become a segment with time scales.
After the electronic equipment determines that the file to be edited is the multimedia file by analyzing the attribute parameters, the electronic equipment can analyze the multimedia format corresponding to the file to be edited and determine the time length corresponding to the file to be edited, so that the starting time and the ending time of each file to be edited on the timeline can be determined according to the time length of each file to be edited. For example, when the electronic device determines that the file to be edited is an audio file in the MP3 format, the electronic device may determine the playing time length of the audio file based on the attribute parameters of the audio file in the MP3 format, and determine the playing start time and the playing end time of the audio file on the timeline according to the playing time length.

The target file is an edited file meeting the requirements of the user. After the user finishes the visual editing, an editing finishing instruction can be input into the electronic device, and correspondingly, the electronic device can receive the editing finishing instruction and merge all the files to be edited on the current timeline to form a target file. For example, an editing completion tag may be set on the electronic device, and the user may click the tag after the editing is completed, and the electronic device may respond to the click operation of the tag to perform a merge operation of the files to be edited, thereby generating a final target file.
In the editing method based on the timeline provided by this embodiment, the attribute parameters of the file to be edited are determined by acquiring at least one file to be edited and analyzing the acquired at least one file to be edited. And determining the time scales of the file to be edited on the time line according to the attribute parameters corresponding to the file to be edited, and visually editing the file to be edited with at least one time scale on the time line to obtain the target file.

Specifically, the step S242 may include:
(1) and acquiring a target time scale corresponding to the target editing file.
The target time scale is the time scale of the target editing file on the current time line. Specifically, the electronic device may analyze the target editing file, obtain a start timestamp and an end timestamp corresponding to the target editing file, and determine a time scale of the target editing file on the timeline according to the start timestamp and the end timestamp.
(2) And sequentially merging the target editing files according to the target time scales to obtain the target file.
The electronic equipment carries out merging operation on the target editing files in at least one format according to the target time scales of the target editing files on the current time line, and therefore the edited target files containing multiple formats can be obtained.
According to the time line-based editing method provided by the embodiment, the target editing file is obtained by visually editing the file to be edited corresponding to at least one time scale on the time line, and the target editing file is synthesized to obtain the target file, so that the time editing limit of the file to be edited is overcome, and the file to be edited in any format is combined while the file to be edited is arbitrarily edited on the time line. And editing at least one file to be edited by responding to an editing instruction of the at least one file to be edited on the time line to obtain a target edited file at the at least one time scale. The editing instruction comprises one or more of a triggering instruction, an adding instruction, a deleting instruction and a dragging instruction. The method realizes the arbitrary editing of the files to be edited in various formats on the time line by responding to the editing instruction of the user on the files to be edited on the time line, thereby meeting the editing requirement of the user on the files to be edited to the greatest extent.
