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.
Fig. 1 is a flow diagram illustrating a method for adding visual objects in a video according to an example embodiment. As shown in fig. 1, the method for adding a visual object in a video includes the following steps:
in step S101, an instruction to add a visual object in a video is received; the instruction contains a current frame image of a video to be edited.
In this embodiment, the visual objects may be static stickers, dynamic stickers, artistic words, etc.; the video to be edited can be imported from a local album, and can also be shot by a user after the authority of opening the camera is acquired.
In step S102, a video editing interface is displayed; the video editing interface comprises a video preview area, a visual object selection area and a visual object configuration area; the video preview area is used for displaying the current frame image; the visual object selection area is used for displaying selectable visual objects; the visual object configuration area is used for receiving configuration information input by a user.
In a possible implementation manner, in order to facilitate a user to see an editing effect of a video to be edited at any time, a video preview area, a visual object selection area and a visual object configuration area are sequentially arranged in a video editing interface from top to bottom. For example, after the user imports the video to be edited from the local album, the first video frame of the video to be edited may be displayed in the video preview area as the current frame image.
In step S103, at least one target visual object selected by the user from the visual object selection area is acquired.
In this step, the user may slide left and right in the visual object selection area to browse the selectable visual objects, and then select the target visual object by clicking.
In step S104, configuration information of at least one target visual object input by a user in the visual object configuration area is received.
For example, if the visual object is a static sticker or a dynamic sticker, the user may configure parameters such as transparency, effective range time range, etc. of the target visual object in the visual object configuration area.
In step S105, at least one target visual object is added to at least one frame image of the video to be edited based on the received configuration information.
Specifically, when the configuration information includes an effective time range, at least one frame image corresponding to the effective time range of the target visual object in the video to be edited is determined, and then the target visual object is added to the determined at least one frame image. For example: the effective time range of the target visual object set by the user is 00:12: 00-00: 12:15, and the frame image needing to be added with the target visual object is each frame image of the video to be edited in the time period of 00:12: 00-00: 12: 15. When the effective time range is not included in the configuration information, the target visual object may be added to all frame images in the video to be edited.
In step S106, in the video preview area, the current frame image to which at least one target visual object is added is displayed.
Therefore, the video editing interface comprises a video preview area, a visual object selection area and a visual object configuration area, so that a user can complete selection and configuration of a target visual object in the interface without repeatedly switching among different interfaces, the process of adding the visual object is simplified, and the operation of the user is facilitated.
Fig. 2 is another flow diagram illustrating a method for adding visual objects in a video according to an example embodiment. As shown in fig. 2, the method includes:
in step S201, after receiving an instruction to add a visual object to a video, a video editing interface is displayed.
Specifically, as in step S101 in the embodiment shown in fig. 1, the video editing interface may include a video preview area, a visual object selection area, and a visual object configuration area. The video preview area is used for displaying the current frame image, the visual object selection area is used for displaying the selectable visual object, and the visual object configuration area is used for receiving configuration information input by a user.
In step S202, at least one target visual object selected by the user from the visual object selection area is acquired.
In step S203, it is determined whether the selected target visual object is a dynamic visual object; if yes, executing step S204; if not, steps S207, S208, S209 and S210 are performed.
Specifically, the dynamic visual object may be a dynamic picture that can be added to the video to be edited.
In step S204, the video preview area is reduced to a preset size, and the dynamic visual object configuration sub-area is displayed in the visual object configuration area of the video editing interface.
Specifically, in the visual object configuration area of the video editing interface, a dynamic visual object configuration sub-area is further displayed, which is used for receiving configuration information input by a user for a selected dynamic visual object.
In step S205, when it is detected that the user clicks the forward/reverse play button in the dynamic visual object configuration sub-area, the target visual object is played in an order opposite to the current playing order of the target visual object.
In step S206, when it is detected that the user drags the playing speed adjustment slider in the dynamic visual object configuration sub-area, the playing speed of the target visual object is increased or decreased according to the position of the playing speed adjustment slider.
In one possible implementation, when the target visual object selected by the user is a dynamic sticker, the video editing interface is as shown in FIG. 3. The interface comprises a video preview area 1, a visual object selection area 2 and a visual object configuration area 3; wherein, visual object configuration area includes: the transparency configuration subarea 3-1, the dynamic visual object configuration subarea 3-2 and the effective time configuration subarea 3-3 enable a user to configure the four parameters of the transparency, the forward/reverse playing, the playing speed and the effective time range of the target visual object in the subareas.
For example, referring to FIG. 3, the forward/reverse play button may configure a triangle button in sub-section 3-2 for the dynamic visual object; the user can change the playing sequence of the target visual object by clicking the triangular button; the circular slider positioned on the right side of the forward/reverse order playing button is used for adjusting the playing speed of the target visual object, and when a user drags the circular slider to the right side, the playing speed of the target visual object is accelerated; when the user drags the circular slider to the left side, the playing speed of the target visual object is slowed down.
In step S207, when it is detected that the user drags the transparency adjustment slider in the transparency configuration sub-area 3-1, the transparency of the target visual object is adjusted according to the value corresponding to the transparency adjustment slider.
In step S208, when it is detected that the user has performed a drag operation on the target visual object in the video preview area 1, the position of the target visual object is moved along with the detected drag trajectory.
In step S209, when it is detected that the target visual object in the video preview area 1 is selected by the user, a visual object edit box is generated, and the target visual object is correspondingly zoomed and/or rotated according to the zoom and/or rotation operation performed by the user in the visual object edit box.
In step S210, when it is detected that the user stops dragging the first slider on the video time axis in the effective time configuration sub-area 3-3, the time corresponding to the first slider is taken as the effective starting time of the target visual object, when it is detected that the user stops dragging the second slider on the video time axis in the effective time configuration sub-area 3-3, the time corresponding to the second slider is taken as the effective ending time of the target visual object, and the time period between the effective starting time and the effective ending time is determined as the effective time range of the target visual object.
In addition, referring to fig. 3, the user may also perform effective time preview by clicking a triangle button located on the left side of the video time axis in the effective time configuration sub-area 3-3 to determine whether the effective range time setting of the target visual object in the video to be edited is reasonable.
In another possible embodiment, if the target visual object selected by the user is static, the video editing interface is shown in fig. 4, and the interface also includes a video preview area 1, a visual object selection area 2 and a visual object configuration area 3; and the visual object configuration area 3 only comprises a transparency configuration subarea 3-1 and an effective time configuration subarea 3-3, so that a user can configure two parameters of the transparency and the effective time range of the target visual object in the area 3.
In another possible implementation, if the target visual object is composed of a text part and an image part, when the visual object is added to the video, whether the user selects the text part of the target visual object or not can be detected; if so, generating a character editing box, and correspondingly changing the character part of the target visual object according to the input operation of the user in the character editing box; and/or, detecting whether the user selects the image part of the target visual object; if yes, generating an image editing frame, and correspondingly zooming and/or rotating the image part of the target visual object according to the zooming and/or rotating operation performed by the user in the image editing frame. For example, referring to fig. 3, when the user selects an image portion in the target visual object, an image edit box is generated around the expression "tongue open", and the user can individually adjust the image portion using the image edit box.
Obviously, the character part and the image part of the target visual object are respectively adjusted, so that the operability of a user and the flexibility in the video editing process are greatly enhanced.
In step S211, it is detected whether the user clicks a confirmation button or a cancel button in the confirmation return function area; if so, step S212 is performed.
