Works on any type of footage

Real-world footage, 3D renderings, motion design work or AI generated clip: Sound Prompter will deliver.

Easy to setup

  1. Note: The unregistered version will contain some gaps and beeps in the output. Register your license to remove this.
  2. Apply the effect to the layer you want to create the SFX for. Can be a subcomp or an adjustment layer to let multiple layers participate in the SFX creation.
  3. Click Add Text Input to add a mask and link it in the "Positive Prompt" field. Then you can change the name of the mask to modify the prompt. Add another Text Input and link in "Negative Prompt" to supress certain keywords (e.g. music).
  4. Click Generate Audio. On the first invocation this might take up to a minute to initialize as the AI model needs to be loaded and the video frames have to be rendered. Once this is done you can iterate on it with different prompts and settings much faster.
  5. Once the computation is done the created audio file (.wav) is written to <home>/Blace Plugins/Sound Prompter Generated Audio and added to your composition above the effect layer.
  6. Premiere: Generated audio files are not added automatically to the timeline, but have to be dragged manually from <home>/Blace Plugins/Sound Prompter Generated Audio into the timeline. We recommend to add the output folder to Favorites in the Media Browser for quick access.
  7. Note: ~18GB VRAM are needed to run the Text+Video XXL model.
