Tencent Hunyuan revolutionizes the world of audiovisual creation with its sound innovation. AI-generated videos often suffer from a lack of immersion, a major challenge for creators. The solution lies in the art of Foley, this essential technique that brings life and texture to every scene.
transcends the limits of audio systems by providing impeccable synchronization between image and sound.
This innovative system uses an impressive database of 100,000 hours of content for high-level learning. The quality of the sound narrative provides a captivating experience, redefining listening in harmony with visual action.
In this quest for excellence, Tencent eliminates the dissonance of traditional assembly by combining advanced technology and aesthetic commitment.
Tencent and audio innovation
A team from Tencent’s Hunyuan lab has introduced a device that revolutionizes audio processing for artificial intelligence-generated videos. Named “Hunyuan Video-Foley,” this tool transforms the audio landscape of digital productions. Designed to analyze videos and produce a high-quality soundtrack, it creates a perfect harmony between sound and the action on screen.
A challenge in the field of Foley
The art of Foley, this cinematic technique of adding realistic sound effects, represents a major challenge for AI. Despite impressive visuals, the absence of sound can annihilate the immersive experience. Sounds of waves, rustling leaves, or the clinking of a glass are essential to provide an authentic dimension to any work.
The limits of traditional models
Video-audio conversion models have often failed to reproduce credible sounds, primarily due to what researchers refer to as a modality gap. AIs could pay more attention to the textual instructions provided than to the actual analysis of the videos. For instance, an instruction simply asking for the “sound of waves” for an animated video of a crowded beach may have overlooked the vital noises of footsteps and bird cries.
Solutions implemented by Tencent
Tencent has addressed these challenges through three major axes. First, the lab has built a library of 100,000 hours of audio, video, and textual descriptions. This vast database allows for enriched AI training, excluding low-quality content sourced from the internet, such as recordings with long silences.
Next, the team designed an innovative AI architecture, enabling it to “multitask” effectively. A particular emphasis is placed on the temporal link between video and audio, ensuring sound synchronization with the image. This methodology allows for better interpretation of the context and overall ambiance of each scene.
Advanced training strategy
Tencent has adopted a training strategy called Representation Alignment (REPA). This process, similar to the intervention of an experienced sound engineer, guides the AI during its learning. This approach ensures that the AI produces clearer, richer, and more stable sound by comparing itself to pre-trained professional audio models.
Promising results
Tests comparing Hunyuan Video-Foley to other AI models have revealed remarkable results. Not only were the metrics measured by computers superior, but human listeners evaluated the output of this tool as being of higher quality. Notable improvements include a greater match between sound and on-screen action, both in terms of content and timing.
A promising future for automated content
The work done by Tencent helps to bridge the existing gap between AI-generated videos that are silent and the immersive experience provided by quality audio. By incorporating elements of the art of Foley into the creation of automated content, Hunyuan Video-Foley could become a major asset for directors, animators, and creators across various fields.
For those interested in artificial intelligence, there are events and conferences such as the AI & Big Data Expo, held in Amsterdam, California, and London, where innovations and discussions on these emerging technologies are on the agenda. An opportunity not to be missed to enrich one’s knowledge in the field.
