Sonilo

Sonilo is an AI tool built around the audio needs of video, with its core positioning being to make music and sound effects fit the video content itself. According to its official introduction, Sonilo's AI can understand your video, match its length, and deliver custom audio in seconds, and can be used to create licensed music and sound effects for videos. It also provides a developer documentation platform, including APIs for video-to-music, text-to-music, video-to-sound-effects, text-to-sound-effects, audio ducking, task polling, and account usage.

1. Main capabilities

2. Video scoring and sound effect generation: After uploading a video, Sonilo analyzes the footage and generates music or sound effects for the video that match its duration. The official description states that it uses only visual information, and you can keep, adjust the volume of, replace, or layer on top of the original audio.

3. Multi-version generation: The official description states that by default multiple variants are generated, making it easy to choose the version that best fits the video, and text prompts are optional.

4. Video translation and dubbing: The same video can be switched to other languages. After uploading once, Sonilo translates the speech and re-dubs it into the selected language as required. The official example is that the same scene can be played in English, Spanish, and Portuguese.

5. Lip sync: Lip movements can be re-rendered to match the new language, or the original footage can be kept and only the sound replaced.

6. Translation proofreading and editing: Before video generation, the translated content can first be proofread and edited. If subtitles already exist, .srt or .vtt files can be uploaded, and the translation will correspond strictly to those dialogue lines.

7. Editor plugins: The official description states that plugins are already available on the Unity Asset Store, Godot, Epic Games Fab, Roblox Asset Store, Defold Asset Store, as well as Adobe Exchange for Premiere Pro, allowing licensed music and sound effects to be generated directly within a project or timeline.

8. How to use Videos in MP4, MOV, or M4V format are supported and can be uploaded directly. For music and sound effect generation, different plans have different limits on the duration and size of uploaded videos. Text prompts are optional, and by default the official service generates multiple variants to choose from. For video translation, the translated text can first be proofread and edited, or .srt/.vtt subtitle files can be uploaded to correspond precisely to the dialogue. Generation billing is based on output duration, and all models share one credit balance.

9. Applicable scenarios The official offering targets creators and brands, and is suitable for short videos, advertisements, brand content, client deliverables, monetizable channels, indie games, as well as more advanced scenarios such as film, television, broadcast, and studio games. The plugin format is suitable for use in Unity, Godot, Epic Games Fab, Roblox, Defold, and Premiere Pro, among other environments.
