The audio is real, recorded by sound designers rather than generative AI, and effects stay in sync when swapped for another option.
Krotos Video to Sound is a Premiere Pro plugin from Krotos Ltd that adds sound effects to a project in seconds, placed directly on the timeline. The workflow is AI-assisted: select a region of your video, choose the type of sound effects to add, and they are synced automatically and immediately on the timeline.
Once placed, effects can be swapped while sync is maintained. All audio is high quality, real audio recorded by sound designers rather than generative AI, so the sound comes from recorded material throughout.
Sound options cover Ambiences, Whooshes, Risers, Impacts and Cloth, with Footsteps listed as coming soon. Version 1.0.0 is compatible with Premiere Pro 25.6.0 and above. Available through Adobe Exchange for Premiere Pro, it brings recorded sound effects onto the timeline through an AI-assisted workflow that keeps them in sync.
Krotos Video to Sound is best for premiere Pro editors adding synced sound effects — Ambiences, Whooshes, Risers, Impacts and Cloth — directly to a timeline.
Krotos Video to Sound is completely free to download and use.
Krotos Video to Sound is compatible with Premiere Pro 25.6.0 and above, as noted in its version 1.0.0 changelog. If you are running that release or a newer one, the plugin should install and run within Premiere. For older Premiere Pro versions the compatibility is not stated, so it is worth updating to 25.6.0 or later before adding it. You can find setup steps on the developer's getting-started page from Krotos.
Krotos Video to Sound offers several categories of sound effects: Ambiences, Whooshes, Risers, Impacts and Cloth, with Footsteps listed as coming soon. You select a region of your video, choose the type of sound effects to add, and they are synced automatically onto your Premiere timeline. Because the effects can be swapped while sync is maintained, you can try different options within a category and keep everything aligned to the same region.
Krotos Video to Sound uses real audio recorded by sound designers, not generative AI, so the sound effects come from recorded material rather than synthesized output. Artificial intelligence is used in the workflow that syncs the effects to your timeline: you pick a region and a sound type, and the AI-assisted process places the audio automatically and in sync. So the automation is AI-assisted, while the audio itself is recorded by sound designers.
Krotos Video to Sound lets you swap sound effects while sync is maintained. After the AI-assisted workflow places audio on your selected region, you can replace one effect with another and it stays aligned to the same spot on the timeline. This means you can audition different Ambiences, Whooshes, Risers, Impacts or Cloth options for the same section without re-syncing each time you make a change.
Krotos Video to Sound is listed as free here. Licensing terms can change, so check the developer's getting-started page for the current details before you rely on it. That page from Krotos also covers how to set the plugin up inside Premiere Pro, which is helpful when you are getting started with syncing sound effects to your timeline. For anything beyond what is shown here, the developer's page is the best source.
