Photographic digital human with an opening in the face
Gaga AI is a video generation model developed by the Sand.ai team that specializes in synchronizing audio and visual elements. Its main goal is to enable a static photo to “speak” in a way that ensures the lip movements match the corresponding audio.
The usage is as follows: simply upload a photo of a person or an audio clip, and the model will automatically generate a high-definition video in which the character’s mouth movements are perfectly synchronized with the audio, resulting in natural expressions. There is no need to write complex instructions. In addition to generating videos based on mouth movements, this technology also supports the creation of videos with both visual and audio elements generated from images or text, as well as functions such as image upsampling, timbre restoration, and the development of multilingual digital avatars.
The main challenges in developing such models lie in the details: the alignment of lip movements with consonant sounds, the subtle movements of the head during speech, and the artificial appearance that results from prolonged immobilization. In these aspects, Gaga’s performance currently ranks among the top; this is especially true in short-sequence scenarios. Such models are ideal for use in real-person short dramas, digital human broadcasts, short-video content, and multilingual voice-over materials.
The official website offers a free trial, and an API platform is also available. It should be noted that generating spoken videos using real-person portraits involves issues related to copyright; therefore, prior authorization from the individual in question is required before such content can be used for commercial purposes.
If you want to use it to create AI-produced short dramas, you can first search for scripts and storyboards on TVLab. There, you will find analyses of popular foreign short dramas, templates for their structural rhythms, as well as inspiration cards with pre-made storyboards. You can simply copy these materials and use them as guides for your own work.
