The user starts browser, logins 105 video editing servers, and in 105 video editing servers registered user name and password, after the registration, the video editing server distributes corresponding authority and related account information for each user.
After the user logins the video editing server, just can select the video editing control in the browser, create video editor, the chained address of opening the associated video in a certain video website then in video editor loads associated video.Suppose, the active user wants the video of " the dimension visitor network of cloud computing " in the Yoqoo is edited, then only need the chained address of this video is added in the video editor of the present invention, be about to http://v.youku.com/v_show/id_XMTMzNjQ5MTY.html and be added into 105 video editors, then this video just may be displayed in the video editor of user's establishment.
Video editor among the present invention, be meant and be used for visual edit control that the video flowing that loads is carried out soft shearing, this control can load the video file of different URL address continuously, and shear out video segment, obtain the relevant information of video and video segment simultaneously, regeneration multisource video description document; Wherein the video segment relevant information comprises the beginning and ending time information or the start-stop frame information of video segment;
After having loaded video to be edited, the user can carry out soft shearing to the video segment of needs; Soft shearing among the present invention is meant the original coding that does not need to change original video, but passes through the frame mode of multisource video description document, the video of heterogeneous networks address is gathered constitute a new video;
The video process of soft shearing separate sources may further comprise the steps:
(1.1) video editor loads video, and writes down the URL address information of described video;
(1.2) time shaft slide block or the video that drags in the video editor play operation automatically, determines that current video treats the position at the start frame place of soft shearing video segment, and adds initial reference mark;
(1.3) be starting point with described initial reference mark, drag the position that time shaft slide block in the video editor or video play to the end frame place for the treatment of soft shearing video segment automatically, and add the finishing control point;
(1.4) video of current loading, the video segment from initial reference mark to finishing control point is the video segment of soft shearing, and the record start reference mark is to the temporal information of finishing control point or the information of frame, and gives serial number of video segment of soft shearing;
(1.5) in video editor to other videos of same video or loading, repeat the step of (1.1) to (1.4), and be a unique serial number of video segment distribution of each soft shearing;
(1.6) video segment of soft shearing can automatically appear in the object tree window.
The process that wherein drags the soft shearing video segment of time shaft slide block is further comprising the steps of:
By dragging the time shaft slide block, add initial reference mark and finishing control point after, can automatically generate a video segment node in the object tree window, simultaneously according to the sequencing of soft shearing, in allocation window, generate corresponding order number automatically;
The video segment of soft shearing number carries out sequencing display in order in object window;
If revise the serial number of the video segment of soft shearing at allocation window, the DISPLAY ORDER of the video segment of then described soft shearing in the object tree window also changes thereupon; Otherwise, according to the series arrangement of the serial number of automatic generation.
It is further comprising the steps of to generate multisource video description document process in the video process of soft shearing separate sources:
(2.1) video editor loads video A, and the URL address information of recording of video;
(2.2) obtain beginning and ending time or the start-stop frame information of video segment a among the video A; In like manner, can obtain other video segment among the video A; Generate the corresponding XML of video A or the multisource video description document of other script;
(2.3) in like manner, repeat (2.2) operation, other video segments of soft shearing, and generate other multisource video description document;
Wherein the multi-source description document can preserve into a local file be saved in network file or network data base in.
The video of separate sources, be meant the video of uploading by subscriber's local or be linked in the video of other website, the video format of supporting include but not limited to avi, mpg, flv, mpeg2, mp3, mp4, h.264, AVS, WMV, 3GP, rm, what deserves to be mentioned is, method and system of the present invention can be supported the various video form, and have cross-platform, as to surmount network structural limitations advantage.Be that the video a that narrates previously can be respectively different video formats with video b, the video website structure at its place and platform also can be different, and in soft shear history, method of the present invention is not limited.
Be example with Yoqoo " the dimension visitor network of cloud computing " again, the time span of supposing this video is 30 minutes, but the user who watches this video is only interested in the video segment between 10 minutes 08 second～20 minutes and 11 seconds, want this part video segment is preserved, then the user can operate with reference to the step of (1.1)～(1.5).When video moves to 10 minutes and 08 second or the user drags time shaft slide block to 10 minute 08 second in video editor, select the configuration module window then, be that an initial reference mark is added in the present frame position of locating in 10 minutes 08 second, the temporal information at present frame place can be write down on the one hand in this reference mark, and how many frames also can write down this frame on the other hand is.Next, the user can continue to watch video to 20 minutes 11 seconds to locate or drag time shaft slide block to 20 minutes 11 seconds to locate, for adding a finishing control point in present frame position herein, the temporal information at present frame place can be write down on the one hand in this reference mark, and how many frames also can write down this frame on the other hand is.At this moment, the video segment that the user needs is from just being got off by soft shearing in logic, finishing control point adds when finishing, and 10 minutes 08 second～20 minutes and 11 seconds video segment just appears in the object tree window with the form of icon, can give its corresponding order number automatically at allocation window simultaneously.As shown in Figure 3, suppose that the video when pre-treatment is the 1st video, and soft shearing is first video segment, after then soft shearing finishes, can generates the video segment of Clip_1_1 in the object tree window automatically.If the user is soft again other video segments of shearing in current video, then can in object tree, generate video segment objects such as Clip_1_2, Clip_1_3, Clip_1_4, Clip_1_5 in proper order.If revise the serial number of video segment, then the video segment object in the selected object tree is made amendment to its serial number in the allocation window of correspondence then, and after the modification, the object tree window can carry out sequencing display again according to new serial number.
In like manner, can edit the corresponding video segment of soft shearing to the video in other video website.Suppose that user's source video sequence to be edited is in another video website, as the potato net, video segment that its editor back is generated then will be shown as Clip_2_1, Clip_2_2, Clip_2_3, Clip_2_4, Clip_2_5 etc. in the object tree window.
The user is to the video of separate sources, sheared the video segment that needs after, if want the video segment of soft shearing is combined,, then need to finish following steps so that watch:
(3.1) choose video segment object to be made up in object tree, combination generates new multisource video, and wherein multisource video and the video segment of choosing that comprises thereof can appear in the object tree window automatically with the icon form;
(3.2) redistribute unique serial number by configuration module for each video segment chosen under the multisource video icon;
(3.3) each video segment of having chosen sorts according to serial number, and shows in the object tree module;
(3.4) click the video segment of having chosen under the multisource video in the object tree, in configuration module, revise the serial number of the video segment of choosing or delete the described video segment of having chosen;
(3.5) after editor finishes, click and preserve, generate the multisource video description document, and the multisource video description document that is generated is saved to server database.
According to step (3.1)～(3.5), the user just can carry out new combination to the video segment of soft shearing, generate a new continuous in logic video, whole constructive process can be described by the multisource video description document, and the main contents of its description comprise:
Write down the link position information of each video resource; Described link position information is meant the local address or the network address;
Write down the All Time axis information of each video;
Write down the initial reference mark of each soft shearing video segment and the position at finishing control point place in current video All Time axle;
Write down the serial number of each soft shearing video segment, write down the timeline information of the multisource video that all soft shearing video segments are constituted simultaneously.
The generative process of multisource video description document comprises among the present invention:
