Mirelo Video To SFX

Generate synchronized sound effects for any video. Perfect for adding realistic SFX to silent footage.

Model Overview

This model generates sound effects that are synchronized with the visual content of a video.

Best At

It excels at adding realistic sound effects to short clips (up to 10 seconds) of silent video, syncing the audio precisely to on-screen events.

Limitations / Not Good At

• Only generates sound effects (not speech or music).
• Truncates videos longer than 10 seconds.
• Audio quality is optimized for effects and syncing, not high-fidelity music or dialogue.

Ideal Use Cases

• Enhancing stop-motion or animated short films with sound.
• Adding ambient sound (rain, birds, etc.) to nature videos.
• Creating SFX for social media videos that are originally silent.

Input & Output Format

• Input: A silent video file (max 10 sec) and an optional text prompt to guide the sound effect. Also, optional parameters: seed and number of samples.
• Output: An array of video files (as URIs) with the generated soundtrack appended to the original video.

Performance Notes

• The model generates 2-4 sound effect variations per run. Processing time is typically a few seconds per variation and may require audio processing resources.
