Simply upload your video and Effct's AI analyzes it frame by frame, identifying scenes, dialogue, and actions. It then generates and syncs appropriate sound effects, enhances your dialogue audio, and creates a professional mix—all automatically.

Where do you get your sound effects?

We use a blend of proprietary sounds our team has recorded and sound effects with a CC0 license, ensuring high-quality audio that's fully cleared for your projects.

What video formats do you support?

We support all major video formats including MP4, MOV, AVI, and MKV. Videos can be up to 4K resolution. The maximum project length is 20 minutes—if you upload a longer video, it will automatically be split into 20-minute sections for processing.

Can I customize the generated sounds?

Yes! Use our Timeline editor to regenerate any sound you're not happy with, adjust the mix levels, add new sound effects, or remove sounds entirely. You have full control over the final result.

What export options are available?

Depending on your plan, you can export a full mix (MP3/WAV), individual stems (dialogue, music, SFX, ambience), or an AAF file with separate tracks for import into professional editing software like Premiere Pro or DaVinci Resolve.

How long does processing take?

Processing time typically takes 0.75-1.5x the video length, so a 2-minute video usually finishes in 1.5-3 minutes. You'll receive a notification when your project is ready.

Is my content secure?

Absolutely. Your videos are encrypted during upload and processing. We don't share your content with third parties, and you can delete your projects at any time. We never use your videos or uploaded content for model training.

Professional sound effects for creators, without the professional price tag

YouTube videos that sound as good as they look

Your audience can forgive a slightly off-white-balance. They won't forgive bad audio. Sound design is the invisible layer that makes YouTube videos feel polished and professional, but most creators skip it because it takes too long. Effct changes that. Upload your edited video, pick a style — Energetic for vlogs and challenges, Playful for comedy, Cinematic for video essays — and get a full sound design pass in the time it takes to write your thumbnail text. Transitions swoosh, impacts land, and your content finally sounds like you want it to.
