The present disclosure relates to a method and apparatus for generating a video, an electronic device, and a computer program product. The method includes obtaining a visual token for generating an image frame in the video. The method further includes obtaining a control token for constraining position information of an object in the image frame. In addition, the method also includes generating the image frame in the video based on the visual token and the control token, where the object in the image frame satisfies the position information.

Method and apparatus for generating video, electronic device, and computer program product

Provided are a method and an apparatus for generating a video, a device, and a medium. In one method, a first reference image and a second reference image are determined from a plurality of reference images in a reference video. A reference text for describing the reference video is received. A generation model is acquired based on the first reference image, the second reference image and the reference text. The generation model is configured to generate a target video based on a first image, a second image and a text. With example implementations of the present disclosure, the second reference image can serve as guiding data to determine a development direction of a story in the video. In this way, the generation model can clearly grasp changes of various image contents in the video, which is beneficial to generating richer and more realistic videos.

Method, apparatus, device and medium for generating a video

An interaction method of audio-video segmentation and apparatus, and a device and a storage medium. The method includes: detecting whether a selected clip exists in a target audio-video; in response to the selected clip existing in the target audio-video, displaying a split button upon detecting that a pointer on a track of the target audio-video is located in the selected clip; and splitting the selected clip, in response to a trigger operation for the split button, based on an intersection position of the pointer and the selected clip. Compared with an interaction means in which a split button resides in a pointer of a track, mis-operations of audio-video splitting can be reduced to the greatest extent, and the usage experience of a user is improved to a certain extent.

Interaction method of multimedia segmentation, apparatus, device and storage medium

Provided in the present application are a method and apparatus for training a visual language pre-training model, and a device and a medium. The method includes: acquiring pairing groups respectively corresponding to N images, wherein the pairing group of a first image includes: a first pairing group which is composed of the first image and description text of the first image, and a second pairing group which is composed of a local image of the first image and description text of the local image, N is an integer greater than 1, and the first image is any one of the N images; and training a visual language pre-training model according to the pairing groups respectively corresponding to the N images.

Method and apparatus for training visual language pre-training model, and device and medium

The present disclosure provides a video processing method, an apparatus, a device and a storage medium. The method includes: after determining a target effect style and determining a target video clip based on presentation of a video to be processed on a timeline, establishing a binding relationship between the target effect style and the target video clip in response to an effect application trigger operation, so as to achieve an effect of applying the target effect style to the target video clip. The embodiment of the present disclosure, by establishing the binding relationship between the target effect style and the target video clip, achieves the effect of effect processing only on a certain video clip of the video, thereby meeting the user's demand of effect processing only on a certain video clip, which increases flexibility of video effect processing, and further improves the user's experience of video effect processing.

Video processing method and apparatus, device, and storage medium

The present disclosure provides an effect application previewing method, an apparatus, a device and a storage medium. The method includes: taking, in response to a preview trigger operation for a target effect style, a position of a pointer on a video track as a start point, to generate a virtual video frame for the target effect style; synchronously playing the virtual video frame and at least one video clip corresponding to the virtual video frame on the video track based on a timeline, to preview an effect of the target effect style applied to the at least one video clip.

Previewing method and apparatus for effect application, and device, and storage medium

The present disclosure provides a subtitle generation method and apparatus, a device, and a storage medium, and the method includes: in response to a subtitle generation triggering operation directed against at least one audio track in a target audio-video file, performing speech recognition on audio data on each audio track respectively to obtain text fragments corresponding to each audio track; and generating subtitles of the target audio-video file based on the text fragments corresponding to each audio track. Compared with a method of performing overall speech recognition on audio data on all audio tracks, in the present disclosure, independent speech recognition is performed on the audio data on each audio track, and thus, the influences of the audio tracks on each other are avoided, so that more accurate speech recognition results can be obtained, thereby improving the accuracy of subtitles generated based on the speech recognition results.

Subtitle generation method and apparatus, and device and storage medium

The present disclosure provides a video dubbing method, an apparatus, a device, and a storage medium. The method includes: when receiving an audio recording start trigger operation for a first time point of a target video and starting from a video picture corresponding to the first time point, playing the target video based on a timeline and receiving audio data based on the timeline; and when receiving an audio recording end trigger operation for a second time point, generating an audio recording file. The audio recording file has a linkage relationship with a timeline of a video clip taking the video picture corresponding to the first time point as a starting frame and taking a video picture corresponding to the second time point as an ending frame.

Video dubbing method, apparatus, device, and storage medium

The present disclosure discloses a method and device for acquiring a road track, and a storage medium. The method includes: acquiring, by a visual odometer, when moving in a collecting area, coordinate information of a location of the visual odometer in real time, and the collecting area being an area where GNSS signals are blocked; and sending, by the visual odometer, the coordinate information to a second device, causing the second device to generate a road track in the collecting area according to the acquired coordinate information.
