Detailed Description
In order to make the technical solutions of the present disclosure better understood by those of ordinary skill in the art, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.
The following description with reference to the accompanying drawings is provided to assist in a comprehensive understanding of the embodiments of the disclosure as defined by the claims and their equivalents. Various specific details are included to aid understanding, but these are to be considered exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. In addition, descriptions of well-known functions and constructions are omitted for clarity and conciseness.
The terms and words used in the following description and claims are not limited to the written meaning, but are used only by the inventors to achieve a clear and consistent understanding of the disclosure. Accordingly, it should be apparent to those skilled in the art that the following descriptions of the various embodiments of the present disclosure are provided for illustration only and not for the purpose of limiting the disclosure as defined by the appended claims and their equivalents.
It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the disclosure described herein are capable of operation in sequences other than those illustrated or otherwise described herein. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Each paragraph (the smallest unit constituting a video film is a shot, and a sequence of shots formed by connecting individual shots together) has a single and relatively complete meaning, such as representing an action process, representing a correlation, representing a meaning, and the like. It is a complete narrative layer in the TV film, just like the scenes in dramas and chapters in novels, and the individual paragraphs are connected together to form a complete TV film. Therefore, the paragraphs are the most basic structural form of the video film, and the structural hierarchy of the video film in the content is expressed by the paragraphs. And the transition or transition between paragraphs and paragraphs, and scenes is called transition.
The transition may adjust the overall transition time. Usually, when the transition processing is performed, the application about the transition may display a corresponding adjustment interface to the user, and the user may set the time length of the transition through the interface, and after the setting is completed, the application completes the corresponding transition according to the newly set total transition time length. For example, a user interface for the transition process is shown in FIG. 1.
Fig. 1 is a user interface for transition processing in the related art.
Referring to fig. 1, a user may select a style of a transition animation effect on a user interface, and then may drag a transition control corresponding to the displayed transition animation effect into the middle of two video clips. When the length of the transition animation effect needs to be adjusted, the transition control can be clicked, and at the moment, a setting window pops up, as shown in fig. 2. The user can input the duration of the transition animation effect in the setting window to complete the setting of the duration of the transition animation effect.
Although the setting of the transition animation effect duration can be realized using the user interface of fig. 1, the adjustment operation is complicated and the time of the front and rear portions of the transition animation effect cannot be adjusted individually.
According to the embodiment of the disclosure, the duration of the transition animation effect can be set by adding the clipping control and dragging the two ends of the clipping control, and the durations of the parts before and after the transition can be adjusted more flexibly. Hereinafter, a method, an apparatus, and a device of the present disclosure will be described in detail with reference to the accompanying drawings, according to various embodiments of the present disclosure.
Fig. 3 is a flow diagram illustrating a video editing method, as shown in fig. 3, that may be used for transition processing between at least two video materials/segments, according to an example embodiment. The method shown in fig. 3 may be performed by any electronic device having an image processing function. The electronic device may be a device comprising at least one of: for example, smart phones, tablet Personal Computers (PCs), mobile phones, video phones, electronic book readers (e-book readers), desktop PCs, laptop PCs, netbook computers, workstations, servers, Personal Digital Assistants (PDAs), Portable Multimedia Players (PMPs), cameras, wearable devices, and the like.
Referring to fig. 3, in step S11, at least two video materials to be spliced are acquired and displayed. For example, when a user inputs two or more video clips (video material) to the electronic device, a user interface for editing the video clips may be displayed, such as shown in fig. 4. Fig. 4 is a user interface for splicing two video materials, shown in accordance with an exemplary embodiment of the present disclosure.
In fig. 4, the user interface may place and display a style button for a transition animation effect and a video clip to be edited.
In step S12, a selection of a transition animation effect for splicing two adjacent video materials is received. The user may select the style of transition animation effect that the user wants to add in the user interface of fig. 4. The user may select a favorite transition animation effect style by touching a style button, or the like.
In step S13, in response to the selection of the transition animation effect, a clip control for changing the duration of the transition animation effect is displayed.
The clip control may be a newly added track after the transition animation effect is selected, and the clip control may be a draggable control.
After the user selects the transition animation effect style, a clip control may be displayed above or below the adjacent two video materials to be edited, as shown in fig. 4. In this way, the user can more conveniently adjust the duration of the transition animation effect with reference to the video.
Alternatively, when a user clips a video, a transition control can be dragged between two video materials that need to be added to the transition when a transition animation effect needs to be added between the two video materials. For example, after the transition control is added, a clip track can be added above or below the currently edited video for placement and display of the clip control.
According to the embodiment of the disclosure, the clipping control part can be arranged to be rectangular and presented in a semitransparent mode, and the left side and the right side of the clipping control part are respectively provided with a handle. However, the above examples are merely exemplary, and the form and shape of the clip control may be differently set. There may also be no "handles" on the left and right sides of the clip control.
The vertical centerline of the clip control may be aligned with the splice of two adjacent video material to be edited, such as shown in fig. 4. However, the above positions are merely exemplary, and the present disclosure is not limited thereto.
The length of the clip control may be displayed proportionally to the duration of the transition animation effect.
To enhance the visualization of the transition animation effect, a progress bar corresponding to the length of time that two adjacent video materials are covered by the transition animation effect may be displayed in the clip control. That is, in the clip control, portions of two adjacent video material that are overlaid by the transition animation effect may be displayed. For example, the black bold bar in the clip control in fig. 4 is the progress bar. The progress bar can reflect the real time length of the transition animation effect, namely the covered time length of the two adjacent videos.
In addition, a label or icon for the user to select the transition animation effect may also be displayed in the clip control, so that the user may more conveniently view the selected transition animation effect.
The user interface shown in fig. 4 is merely exemplary and may be differently laid out and arranged according to design requirements.
In step S14, the duration of the transition animation effect is changed based on the change in the length of the clip control. The length of the clip control may be varied according to the user. For example, the user may individually change the length of the clip control by dragging the left or right end of the clip control.
After receiving a user input for dragging at least one of the left and right ends of the clip control, the length of the clip control may be changed to change the duration of the transition animation effect according to the user input. Specifically, the duration of the first half of the transition animation effect, which corresponds to the first of the two adjacent video materials, may be changed based on the left end of the clip control being dragged, and the duration of the second half of the transition animation effect, which corresponds to the second of the two adjacent video materials, may be changed based on the right end of the clip control being dragged.
In order to adjust the transition animation effect duration more intuitively and conveniently, the length of the clipping control can be divided into two parts, one part corresponds to the first half of the transition animation effect, the other part corresponds to the second half of the transition animation effect, correspondingly, the first half of the transition animation effect can correspond to a first video material (such as a video clip positioned at the front of two video clips), and the second half of the transition animation effect corresponds to a second video material (such as a video clip positioned at the rear of two video clips).
By way of example, when the duration of the transition effect needs to be adjusted, two ends of the clip control can be dragged, and the duration of the transition animation effect is correspondingly adjusted according to the change of the length of the dragged clip control. When the transition animation effect includes two animation effects (e.g., a front animation effect and a rear animation effect), if the left side of the clip control is dragged, the duration of the front animation effect may be adjusted, and if the right side of the clip control is dragged, the duration of the rear animation effect may be adjusted.
When the left end of the clipping control is dragged, the change of the progress bar in the clipping control, which corresponds to the duration of the first half of the transition animation effect, is correspondingly displayed. When the right end of the clipping control is dragged, the change of the progress bar in the clipping control, which corresponds to the duration of the animation effect of the latter half of the transition animation effect, is correspondingly displayed. That is, the timeline in the clip control corresponding to the transition animation effect will change accordingly based on the clip control being stretched left or right.
For example, in the case where the transition animation effect includes the first animation effect and the second animation effect, when the user drags the clip control to the left, the duration of the first animation effect becomes long, and the progress bar in the clip control corresponding to the first animation effect also correspondingly stretches to the left. When the user drags the clipping control to the right, the duration of the second animation effect is prolonged, and the progress bar corresponding to the second animation effect in the clipping control correspondingly stretches to the right. The above examples are merely to illustrate the display effect, and the present disclosure is not limited thereto.
The process that the video is completely shielded may occur in the transition process, and accordingly, the duration that the video is completely shielded can be displayed in the clipping control, so that when the user adjusts the clipping control by dragging, the user can also see the corresponding duration change, and the required effect can be adjusted more accurately.
In addition, the user may also change the previously selected transition animation effect through the clip control. For example, each time the user touches an icon of a transition animation effect in the clip control, the current transition animation effect may be changed once in the order of transition animation styles in the user interface. However, the above examples are merely exemplary, and the present disclosure is not limited thereto.
In step S15, two adjacent video materials are spliced according to the changed transition animation effect to obtain a merged video material.
After the transition animation effect is adjusted, the transition animation effect can be inserted between two adjacent video segments to obtain a combined complete video.
According to the embodiment of the disclosure, the duration of the transition animation effect can be set by dragging the clipping control, and the durations of the front part and the rear part of the transition animation effect can be independently adjusted, so that a user can adjust the transition animation effect more conveniently and accurately.
