What is Aimi Sync?

How to use Aimi Sync?
Upload a video, pick a genre, and Aimi Sync scores it, including voice-over and vocals. No music or audio production skills are needed.
Is the music really royalty-free?
Yes! All audio output from Aimi is broadcast-safe and warranted 100% copyright and royalty free. You can safely use your royalty-free soundtrack globally. And since we do not train our models on other people’s creative works, you can take comfort knowing you are not undermining the artist economy.
Can I use the audio output separately?
You have a license to the soundtracks generated by Aimi for use with the videos they are generated for. They are not licensed for use as standalone music. This is done to ensure that AI generated music is not used as spam on DSPs which ultimately hurts artists and the artist economy.
How long a video can I upload?
Aimi Sync’s advanced AI music generator is not limited in audio length. Therefore you can upload any length video and have cohesive music for the entire video, scene by scene. The free tier supports videos up to 5 min. If you need to score longer videos, you can upgrade to paid plans.
Is there a free option?
Yes, when you sign up, you can use Aimi Sync for free! There are no limits on how much you use the service. You can upload and generate as many soundtracks as you need. The free tier is limited to videos 5 min in length.
Why does it sometimes take a long time to process videos?
Video processing is more a function of total pixels than length of video. This means shorter videos with higher resolution might take longer to process than longer videos with lower resolution.
How does Aimi Sync work?
Aimi Sync is based on Aimi’s AI music generator that has redefined the possibilities with AI generated music for creators, developers, and enterprises. Learn how in our blog post.
Can I really score unlimited videos on the free plan?
Yes. You can generate as many 5-minute tracks as you like. Each export contains a brief “music by Aimi” audio tag and a watermark. Upgrade to a paid plan to remove the tag and lift the per-video length cap.
What if I my video is longer than the length cap?
If you need to process longer videos, you can upgrade to a higher tier. Creators get 10 min videos. Studio users get 30 min. Pro users can upload any length video. There are no limits on how many videos you can process!
Is the creator license good for montised YouTube channels?
Absolutely. Creator covers videos on channels you personally own and monetise with ads or sponsorships. If you create videos for a company or client you’ll need the Studio (business) licence.
What do full stems mean?
Drums, bass, pads, keys, vocals, FX—every instrument group on its own WAV track. Pro also lets you export per-scene stems for precise remixing. You are free to modify the stems as needed. The stems are licensed for use only with your video.
