Create AI videos with anyone's audio. Free & offline

 

Creating AI videos with custom audio, free and offline, is a tall order since most tools require internet access for processing or have paid components. However, based on what’s out there, here’s the closest you can get:

VACE by Alibaba is a standout option. It’s an open-source video generator that runs locally on your laptop, meaning no internet is needed once installed. It’s free, built on Alibaba’s Wand 2.1, and works with modest hardware (16GB VRAM or less). You can create videos from text or images and add your own audio files to sync with the visuals. The catch? Setup requires some technical know-how, like installing dependencies on your system. It’s not plug-and-play, but it’s powerful for generating uncensored, high-quality videos offline. Check the VACE GitHub or Alibaba’s open-source docs for installation guides.

Wondershare Virbo offers an offline desktop version for Windows, but it’s not fully free. The free plan includes watermarked videos, and you’d need a paid license for watermark-free output. It supports adding custom audio or voiceovers to AI avatar videos, with 350+ avatars and 460+ voices. You can import audio files to sync with the avatar’s lip movements. It’s user-friendly but requires an initial download and occasional online checks for updates.

Limitations: Truly free, fully offline tools with seamless audio integration are rare. Most AI video tools (like Invideo AI, Vidnoz, or Synthesia) are cloud-based and need internet access. Offline options often demand technical setup or have restricted free features. For audio, ensure your files are high-quality (MP3/WAV) to avoid sync issues.

Steps for VACE (Basic Workflow):

1. Install VACE from its GitHub repo (follow system-specific instructions).
2. Prepare your text prompt or reference image for the video.
3. Import your audio file into the tool’s interface.
4. Generate the video, tweaking settings to align visuals with audio.
5. Export the final video locally.

If you’re okay with some online setup, VACE is your best bet for free and offline. Otherwise, Virbo’s desktop app is a solid alternative if you can handle watermarks or pay for premium. Got a specific audio or video style in mind? Let me know, and I can narrow it down further.
