Google DeepMind has introduced a new technology called video-to-audio (V2A) that generates synchronized soundtracks for videos using video pixels and text prompts. This advancement allows for the creation of rich soundscapes for silent videos, enhancing the overall viewing experience. The V2A system can produce various soundtracks for any video input, offering users the ability to guide the generated output towards desired sounds. By encoding video input and refining audio through a diffusion model, the technology aligns audio closely with visual prompts, creating realistic audio outputs. However, challenges such as maintaining audio quality with varying video inputs and improving lip synchronization for speech in videos are being addressed through ongoing research. DeepMind emphasizes responsible AI development, incorporating diverse perspectives to ensure the technology's positive impact and safeguarding against potential misuse through watermarking AI-generated content. Rigorous safety assessments are planned before wider public access to the V2A technology.

10 commentsBut I literally can't keep track anymore of which AI generative combinations of modalities have been released.
Crazy how two years ago this would have blown my mind. Now it's just, OK sure add it to the pile...
If the sound is already being generated at a specific time, surely you can make it generate an output that can be consumed by existing audio mixing tools for further refinement.
The problem with doing these all-in-one integrated solutions is that you're kinda giving people an all-or-nothing option, which doesn't seem that useful. Maybe I'll end up being proven wrong.
