  • Patent number: 12347459
    Abstract: A method and an apparatus for generating a video file, a terminal, and a storage medium are provided. The method includes: presenting, in response to a received video editing instruction, a video editing interface; determining, in response to a clicking operation on a button in the video editing interface, a target audio and a target image for video synthesis; obtaining an audio parameter corresponding to each audio frame; generating a spectrogram corresponding to each audio frame based on the audio parameter; generating, based on the spectrogram and the target image, multiple video frame images that each corresponds to one of the audio frames and includes the spectrum corresponding to the one of the audio frames; and performing, based on the multiple video frame images and the target audio, video encoding to obtain a target video file.

  • Patent number: 12002160
    Abstract: An avatar method, apparatus and device, and a medium are provided. The method includes: acquiring a target image in response to a user input; and obtaining an avatar corresponding to the target image by using a first generator; the first generator being trained and obtained on the basis of a first sample image set and a second sample image set generated by a three-dimensional model. In the present disclosure, by using the first generator, the generation method for an avatar is effectively simplified, thus improving generation efficiency, and avatars in one-to-one correspondence to target image can be generated, so that the avatars are more diversified. Additionally, the first generator is easy to deploy in various production environments, thus reducing the performance requirements on hardware devices.
