Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
As shown in fig. 1, this embodiment provides an online collaborative video editing method applied to a cloud, where the online collaborative video editing method includes:
s110: receiving a video creation request from an editing terminal;
s120: responding to the video creating request, creating a target video and returning address information of the target video to the editing terminal;
s130: dividing the target video into a plurality of editing units, wherein editing authorities of different editing units can be opened to different editing terminals;
s140: receiving editing instructions of different editing terminals to different editing units;
s150: and responding to the editing instruction, and simultaneously carrying out video editing on different editing units.
In the embodiment of the application, the cloud is formed by one or more servers located on a network side.
The editing terminal may be a mobile phone, a tablet computer, a wearable device, or a Personal Computer (PC). In some embodiments, the editing terminal herein may be a consumer terminal of a consumer. In other embodiments, the editing terminal can also be dedicated to a dedicated device for video editing.
After a video creation request is received from an editing terminal, at least a video file of a target video is created in the cloud.
Further, the cloud end can create a folder of the target video according to the video creation request, wherein the folder of the target video comprises: video files of target videos, files of video editing materials, configuration information of editing authorities and the like.
After the target video is created, address information is returned to the editing terminal that requested the creation of the target video.
The address information may be a link address of the aforementioned target video or a link address of the target folder.
In one embodiment, in order to implement collaborative online editing of multiple editing terminals, so as to prevent different editing terminals from performing conflicting editing operations on a target video, the target video is divided into multiple editing units. One of the editing units may be a target video segment of a preset duration.
In other embodiments, different materials of the target video may be edited and divided into editing units according to the editing authority. For example, an image editing unit, an audio editing unit, a subtitle editing unit, and/or a special effect editing unit, and the like. The image editing unit is used for editing the video frame; the audio editing unit is used for performing music or dialogue editing of the video. The subtitle editing unit is used for editing subtitles in an image frame of a video. The special effect editing unit is used for editing the special effect of the video.
In the embodiment of the present application, when online collaborative editing is performed, due to the fact that different editing units are edited by different terminals, editing conflicts of a target video can be avoided, for example, completely opposite editing operations are performed on the same video frame, so that collaborative editing is simply and conveniently achieved, editing efficiency is improved, and communication cost between different editing terminals of collaborative editing is reduced.
Further, the method further comprises:
and configuring editing authority for each editing terminal at the cloud.
For example, the cloud may automatically grant the maximum editing right to the editing terminal (or editing account) requesting to create the target video.
For another example, the editing authority is granted according to the editing terminal requesting to create the video or another editing terminal (editing account) other than the editing terminal or the editing account, and the editing authority of the other editing terminal may be equal to or smaller than the editing authority of the editing terminal requesting to create the video. Specifically, for example, according to an instruction of an editing terminal (editing account) requesting to create a video, editing rights of one or more other editing terminals (or editing accounts) are granted. The cloud end can also recycle the editing authority of one or more other editing terminals or modify the editing authority of one or more other editing terminals according to the indication of the editing terminal (or the editing account) requesting to create the target video. For example, the editing authority of other editing terminals to different editing units is modified. If the effect of a certain editing unit reaches the expected effect, a stop instruction of an editing terminal (or an editing account) requesting to create the target video may be received, and the receiving of the instruction will recover the editing authority of other terminals having the editing authority for the specific editing unit.
For example, the authority range of the editing authority may be the editing authority for all editing units or may be the editing authority for a part of editing units.
In some embodiments, the editing authority of the editing terminal may be further classified into levels, for example, when the editing terminal of the first priority and the editing terminal of the second priority edit the same editing unit, the editing of the editing terminal of the second priority is masked in response to the editing of the editing terminal of the first priority. The first priority is higher than the second priority.
In some embodiments, the method further comprises:
after receiving an editing instruction of an editing terminal, verifying whether the editing terminal has an editing right;
after the verification is passed, determining whether to respond to an editing instruction of the editing terminal; and if the verification fails, shielding the editing instruction of the editing terminal, and if the editing instruction of the editing terminal is shielded, sending second prompt information to the corresponding editing terminal, wherein the second prompt information is used for prompting that the corresponding editing terminal does not have the editing authority.
The verification information for verifying the editing right includes, but is not limited to: and editing terminal information or an authorized password of the terminal. The terminal information includes but is not limited to: and the editing account, the communication identifier and/or the equipment identifier used when the editing terminal requests editing. Communication identities include, but are not limited to, communication accounts for cell phones and/or instant messaging, and typical communication accounts for even communication include, but are not limited to: the account number of the payment account is micro-signal, micro-blog number, face book number, payment account number and/or Beijing east account number. The authorized password can be a password issued by the cloud and/or a password configured by an editing terminal requesting to create the target video when the editing right is granted. The device identification includes but is not limited to: international Mobile Equipment Identity (IMEI)).
In some embodiments, the address information of the target video is secret information, and the cloud only issues the address information to the editing terminal with the editing right, so that only the editing terminal with the editing right can search the target video according to the distributed address information and edit the target video. At this time, the cloud can omit the verification of whether the editing terminal has the editing authority, and the operation of the cloud is simplified.
In order to further reduce the editing conflict of different editing terminals during collaborative editing, in an embodiment of the present application, the method further includes:
and setting the state of the editing unit according to whether the editing terminal edits one editing unit.
The state of an editing unit includes: locked and unlocked states.
In the locked state, the corresponding editing unit only allows one editing terminal editing the editing unit to edit, and the editing of the editing unit by other editing terminals is shielded.
In the unlocked state, the first editing terminal is allowed to edit the editing unit, or the editing terminal with the highest priority is allowed to edit the editing unit.
After all the editing units are divided into editing units, the original state of each editing unit is the unlocked state.
As shown in fig. 2, the S150 further includes:
s151: receiving an editing instruction of a first terminal in the editing terminals to a first unit in the editing units;
s152: checking whether the first unit is in a locked state;
s153: if the first unit is in the locking state edited by a second terminal of the editing terminal, the editing instruction of the first terminal is shielded.
After receiving an editing instruction of an editing terminal authorized to edit, the cloud end firstly shields the editing instruction of the editing terminal according to the state of an editing unit (namely a first unit) indicated by the editing instruction if the editing unit is in a locked state, so that the conflicting editing operations of two or more editing terminals on the same editing unit are reduced.
In the embodiment of the present application, the first unit is any one of a plurality of divided editing units. The first terminal and the second terminal are just used for distinguishing two editing terminals. The first terminal may be any terminal authorized to edit the target video, and the second terminal may be any editing terminal other than the first terminal authorized to edit the target video.
Further, the method further comprises:
after an editing instruction of the first terminal is shielded, first prompt information is sent to the first terminal, wherein the first prompt information is used for prompting that the first unit is being edited by other editing terminals.
If the first unit which the first terminal requests to edit is in the locked state, on one hand, an editing instruction of the first terminal is shielded, so that the phenomenon of editing conflict between the first terminal and a second terminal which is editing the first unit is reduced, on the other hand, the cloud end sends first prompt information to the terminal, the first prompt information informs a user that other editing terminals exist or the user is editing the first unit, namely, informs the user of the reason that the editing instruction cannot be responded, and therefore user experience is improved.
In some embodiments, the first prompt information further carries: the identification information of the second unit currently in the unlocked state. The first unit and the second unit are both any editing unit belonging to the editing units, but the first unit and the second unit are different. Therefore, if the first prompt information carries the identification information of the second unit in the unlocked state, the editing terminal with the editing authority of the second unit can conveniently select to edit the second unit in time, and therefore editing conflicts of subsequent editing instructions sent by different editing terminals to the same editing unit are reduced.
In some embodiments, as shown in fig. 3, the S150 may further include:
s154: if the first unit is in an unlocked state which is not edited by the second terminal, the first unit is edited by responding to an editing instruction of the first terminal;
s155: and locking the first unit edited by the first terminal to control the first unit to enter a locked state.
If the first unit is currently in an unlocked state which is not edited by other editing terminals, the editing instruction of the first terminal is responded, and therefore the cloud end edits the first unit according to the editing instruction of the first terminal.
When it is determined that the first unit is to be responded to the edit instruction of the first terminal, the state of the first unit is switched to the locked state.
In some embodiments, the method further comprises:
and when the editing of the first unit by one editing terminal is finished, unlocking the first unit to control the first unit to enter the unlocked state.
After an editing terminal, for example, the first terminal or the second terminal finishes editing the first unit, the state of the first unit is switched, so that the first unit is switched from the locked state to the unlocked state, and the subsequent editing of the first unit by any terminal is facilitated.
In some embodiments, the S130 may include:
dividing a plurality of time axes of the target video into a plurality of editing units to be edited according to the time sequence, wherein the time axes comprise: a video axis, a subtitle axis, a music axis, and/or a filter axis;
the method further comprises the following steps:
and acquiring video materials of different editing units.
The manner of acquiring the video material of different editing units here includes, but is not limited to, at least one of the following:
receiving video material from one or more editing terminals;
selecting video materials stored locally in a cloud according to the indication of one or more editing terminals;
and downloading the video material from the network according to the indication of one or more editing terminals.
Video material herein includes, but is not limited to, at least one of:
image frame, background music, caption, bullet screen content and special effect content.
As shown in fig. 4, this embodiment provides an online collaborative video editing method, which is applied to an editing terminal, and the method includes:
s210: sending a video creating request to a cloud;
s220: receiving target video address information returned based on the video creation request;
s230: receiving a collaborative editing input;
s240: and sending an editing invitation link carrying the target video to other editing terminals based on the address information according to the collaborative editing input, wherein the editing invitation link is used for enabling the other editing terminals and the editing terminal to collaboratively online different editing units of the target video at the same time.
In the embodiment of the present application, the editing terminal may be a consumer terminal of an ordinary consumer, such as a mobile phone, a tablet, or a wearable device.
The editing terminal may be installed with an online video editor, which may be an Application (APP), applet, fast Application or web page type online video editor, for example.
And if the application interface of the online editor receives a user input instruction to create a video, the online video editor sends the video creation request to the cloud. If the cloud creates the target video, the address information of the target video is received. The editing terminal requesting creation of the target video may assign an editing right to the other editing terminal according to the address information.
For example, the editing terminal may directly forward the address information to other editing terminals, so as to authorize the editing rights of other editing terminals.
For another example, the editing terminal sends a configuration instruction of the editing permission to the cloud according to the address information; the configuration command carries the address information and information of other editing terminals.
The address information is used for locating the video to be edited, which is authorized to edit the authority to other editing terminals, by the cloud.
Other editing terminal information includes but is not limited to: and editing the communication identification, the equipment identification or the editing account of the terminal. The editing account can be an account allocated by the cloud.
In some embodiments, the configuration instruction carries the address information and an authorization password. The editing terminal issues the authorization password to other editing terminals authorized to edit the authority, and meanwhile, the authorization password is reported to the cloud, so that the cloud can conveniently verify whether the editing terminal has the authority.
In some embodiments, the method further comprises:
sending an editing instruction to the cloud;
