Introducing Video to Sound: make space for the work only you can do

Bring your edits to life in seconds

Upload a video and get high-quality, real audio synced perfectly to every scene. From a buzzing café to a city street or office corridor. We built Krotos Video to Sound to take care of the time-consuming parts, so you can stay focused on the creative work that actually needs you.

Powered by real recordings, not Generative AI; this is sound design ready to perform, customise, and mix. And every stem is yours to shape however you like.

Why users love it

• Instant cinematic sound: Rough cuts feel polished from the first play.
• 10x faster workflow: Add complex ambiences in minutes, not hours of library search and syncing.
• Creative control: Download every stem to remix, replace, or layer your own sounds.
• No Generative AI - Professional quality only: Real recordings from Krotos’ award-winning sound designers, never synthetic or artificial. Learn more about our ethical approach to AI at Krotos.
• Commercially safe: All sounds are royalty-free and cleared for production use.

How it works

1. Upload a video.

As a new user, you will get 1 free analysis of a video up to 5 minutes long.

Krotos Studio Pro gives you upto 100 videos per month (5 minutes each)

Krotos Studio Max gives you up to 200 videos per month (20 mins each)

2. Our non-generative AI analyses each scene and adds synced, real audio (at this time only background ambiences will be added, more use cases coming soon).

3. Download a stereo mix, stems, or a version of the video with sound embedded.

If you're trying Video to Sound for the first time, you can upload your video, preview the results and download the mix and stems. If you want to continue and analyse more videos after this, you can join either our Krotos Studio Pro, or Krotos Studio Max plans.

It's that simple. No software install is required, as Video to Sound runs directly in your browser. Your content is never used to train the AI.

API access for enterprise

Looking to scale beyond single projects or short videos? Video to Sound is also available via API integration for studios, broadcasters, and enterprise teams.

• Automate workflows: batch process dailies or rough cuts at scale.
  
• Seamless integration: S3 watch-folder triggers, Pro Tools template creation, or custom pipeline hooks.
  
• Custom libraries: connect your own sound assets for brand-consistent results.
  
• Enterprise-grade security: no training on uploads, all outputs rights-cleared.
