Referring to fig. 2, a flowchart of a first video data generating method according to an embodiment of the present disclosure is shown, where the method includes steps S101 to S104, where:
s101, displaying a plurality of material fragments in electronic equipment, wherein the material fragments comprise preset virtual objects and action information of the virtual objects; the virtual object is generated by virtual object information in the 3D rendering environment after rendering.
The material segment refers to a part of original material provided by the electronic equipment. In this embodiment, the material segment includes a preset virtual object and motion information of the virtual object. In other embodiments, the material segment may further include environmental information in which the virtual object is located.
Specifically, virtual objects are generated after virtual object information in a 3D rendering environment is rendered, and the virtual objects are driven by control information captured by a motion capture device, so that motion information of the virtual objects is formed.
The 3D rendering environment may be a 3D engine running in the electronic device, capable of generating image information based on one or more perspectives based on the data to be rendered. The virtual objects are character models that exist in the 3D engine, and the corresponding virtual objects can be generated after rendering. In the embodiment of the present disclosure, the virtual object may be an avatar, or the like. In other embodiments, the virtual object may also be a virtual anchor or the like.
Illustratively, one form of the virtual object is to capture control information for the motion capture of the actor (person in the middle), drive the virtual object in the 3D engine to act, and at the same time acquire actor sound, fuse the actor sound with the virtual object picture, and generate a material segment.
The motion capture device comprises at least one of a limb motion capture device (such as clothing) worn on the body of the actor, a hand motion capture device (such as glove) worn on the hand of the actor, a facial motion capture device (such as a camera), and a sound capture device (such as a microphone, a laryngeal microphone, etc.).
Specifically, a plurality of optical marking points may be provided on the clothing and glove of the actor, the optical marking points may be made of a reflective material, and then position information of the plurality of optical marking points may be acquired through the image pickup device, and thus control information of the virtual object may be acquired. In addition, a plurality of sensors can be arranged on the motion capture device, and the position information, the moving speed and the moving direction information of the actors can be obtained through the sensors, so that the control information of the virtual object can be obtained.
S102, determining a plurality of target material segments from the plurality of material segments in response to a selection operation of a user.
The target material segment refers to a material segment selected by a user from a plurality of material segments. Different material segments are used for reflecting different virtual objects or different action information, for example, the material segments can be that the virtual object A is lifting a hand, can also be that the virtual object A is turning, can also be that the virtual object B is turning, and the like, and the method is not limited in detail.
For example, referring to fig. 3, a plurality of material segments may be displayed in the electronic device for selection by a user, where the material segment selected by the user is the target material segment. As shown in fig. 3, the plurality of material segments may include a material segment 1, a material segment 2, a material segment 3, and a material segment 4. For example, if the material segment 1 is selected by the user, the material segment 1 is determined to be the target material segment.
Specifically, if the trigger identifier "add" of a certain material segment is triggered, it may be determined that the material segment is selected by the user, for example, if the trigger identifier "add" corresponding to the material segment 1 is triggered, it is determined that the material segment 1 is a target material segment, and meanwhile, if the trigger identifier "add" corresponding to the material segment 3 is triggered, it is determined that the material segment 3 is also a target material segment, and finally, if the "determine" identifier is triggered, it is determined that the material segment 1 and the material segment 3 are target material segments. Of course, in other embodiments, the trigger may also be presented in other forms (such as a specific icon), and is not limited in particular.
S103, determining transition data among different target material segments.
After determining a plurality of target material segments from the plurality of material segments, transition data between different target material segments may be determined. The transition data are used for better connecting two adjacent different target material fragments. In this embodiment, the transition data is obtained automatically by determining the combination sequence between different target material segments. In other embodiments, the transition data may also be transition data selected by the user from a transition database according to the production requirements.
In particular, the transition data may include a trick fragment transition and a no trick fragment transition. The transition of skill fragment is completed by using special effect, mainly has the modes of fade-in fade-out, fold-in fold-out, scratch-in scratch-out and the like, and can well play roles of separating paragraphs, scene transition, up-and-down and the like. The non-skill fragment transfer is a direct fragment switching mode, comprising a similar fragment transfer mode, a transfer mode by using contrast factors and the like, and the mode can lead the connection between the material fragments to be more natural and smooth, have faster rhythm and stable picture.
And S104, generating video data based on the target material fragments and the transition data.
After determining the transition data between different target material segments, video data may be generated from the plurality of target material segments and the transition data. Where video data refers to a sequence of consecutive images, it will be appreciated that video is typically composed of pictures belonging to video frames and/or sounds belonging to audio frames.
In the embodiment of the disclosure, the plurality of material segments are displayed in the electronic device, then the selection operation of the user is responded, the plurality of target material segments are determined from the plurality of material segments, the transition data among different target material segments are determined, and finally the video data are generated, so that the target material segments can be determined according to the requirements of the user, the participation degree of the user in the video generation process is improved, the transition data can be automatically acquired according to the target material segments, the connection relation among the different material segments is increased, the effect of final video presentation is consistent, and the viewing experience of the user is improved.
Referring to fig. 4, a flowchart of a second video data generating method according to an embodiment of the present disclosure includes the following steps S201 to S205:
S201, displaying a plurality of material fragments in an electronic device, wherein the material fragments comprise preset virtual objects and action information of the virtual objects; the virtual object is generated by virtual object information in the 3D rendering environment after rendering.
Step S201 is similar to step S101, and will not be described herein.
S202, determining a plurality of target material segments from the plurality of material segments in response to a selection operation of a user.
Step S202 is similar to step S102, and will not be described herein.
S203, determining the combined connection sequence among the plurality of target material fragments.
After the target material segments are determined, the order of the combined connection between the plurality of target material segments needs to be further determined.

In this embodiment, because the in-process of showing is that the illumination effect, shadow effect and filter effect are adjusted in real time respectively, so, can present a richer bandwagon effect, promoted the picture bandwagon effect.
It may be appreciated that in the embodiment of the present disclosure, the adjustment of the display effect of the AR screen may be performed in response to the operation of the user, or the electronic device may automatically perform the adjustment according to the current display effect of the AR screen, which is not limited herein.
And S3053, generating the video data based on the adjusted AR picture and the transition data.
In this embodiment, in the process of displaying the content of the target material segment, the display effect of the AR picture is adjusted in real time, so that not only the picture content can be enriched, but also the picture display effect can be improved.
