AI Music Generator - Filmora 对比 Aimi.fm

Filmora's AI Music Generator lives inside the Filmora video editor and builds custom background tracks for your timeline. Pick a genre, mood, and video type, or let Smart BGM Generation analyze your footage and produce music that matches its length and tone. Tracks are royalty-free and cleared for commercial use on platforms like YouTube.

Two workflows cover most projects. AI Music Generation lets you fine-tune output with genre, mood, and video-type controls, plus a built-in prompt library for faster iteration. Smart BGM Generation is a one-click option that reads scene transitions, rhythm, and emotional tone from your edit, then loops or fades the track to fit clips from 30 seconds to full-length documentaries.

Filmora supports Normal and Advanced (ToMoviee 2.0) generation modes, exports audio in formats like MP3, AAC, and WAV, and runs on desktop plus iOS and Android through the Filmora mobile app. Volume, fade, and audio balance controls sit in the same editor where you cut footage, add transitions, and layer text.

Aimi.fm 利用授权艺术家音轨构建免版税音乐，而非抓取受版权保护的录音，然后通过 Aimi Sync 引擎为视频配乐。上传视频片段后，Sync 会逐帧分析场景，创作匹配的配乐，支持选择性添加人声、旁白及可下载的音轨。公共主页现已预告即将重新上线，但 Sync 的定价、文档和关于页面显示公司仍在为创作者和开发者提供工具。

与仅生成静态片段的提示词生成器不同，Aimi Sync 将视频视为提示词，并根据场景切换调整时长。音乐来源于由 Aimi Script 和 AMOS 引擎编排的人声录制样本库 Sonic Vault，且每个音轨的使用都会记录在账本中以便支付艺术家报酬。正是这种以样本为先的模式，使 Aimi.fm 拥有超过 60 项专利，并将自身定位为与基于大型唱片目录训练的工具不同。

为制作 Reels、教程和客户作品配乐的视频创作者，在付费套餐中可无限导出，免费方案支持 1 分钟片段。独立音乐人可上传音轨至 Sonic Vault 并通过微量使用获得收益。开发者可申请 Sync API，将具备场景感知且版权清晰的配乐嵌入应用，无需自行处理授权。
