Krotos Video to Sound: AI-powered automatic synchronization

Video to Sound's browser-based platform Krotos uses AI-assisted technology to automatically sync professionally recorded audio with video.

Developed for sound designers, editors, filmmakers and content creators, Krotos Video to Sound generates sound in minutes, accelerating the early stages of post-production so users can focus on the most important creative decisions, as the company has shown during its recent participation in IBC 2025.

Unlike generative AI platforms, Video to Sound is based entirely on licensed and recorded sounds professionally from the library Krotos Studio Pro. The system analyzes the uploaded video clips, detects scene changes and produces synchronized sound, starting with environments and later adding Foley effects and other elements.

Users can listen to the results in the browser and then download a stereo mix and sequences to import into any DAW or NLE for detailed editing.

Video to Sound is designed to Help video editors produce edits with sound to impress your clients, to the audio designers Get a first impression that you can creatively refine, to the video game equipment to create prototypes of environments for images, and to the content creators Make your videos stand out with professional audio.

“Krotos created Video to Sound to take care of the laborious groundwork of sound design, so that professionals can focus on the work that only they can do - he points out Orpheus Boteas, CEO of this company. By combining speed with professional quality audio, “A bridge of quick results and creative control is achieved”.

The video to sound function is being implementing in stages. Krotos has opened one hundred early access spots for users to try it out, and those selected will receive a month of free access and the opportunity to contribute to the development.

After the early access period, will be available in beta version as part of subscriptions to Krotos Studio Pro and Max, with API access available for enterprise customers.
