Short answer

To make AI videos locally without ComfyUI's node graphs, use Cubric Studio: a free, open-source local AI video generator for Windows, macOS and Linux.

What this local AI video generator does

Text to video: describe the shot and press Cue.
Image to video: bring a still to life, and guide it with a first and last frame.
Extend a video past its last frame, sound and all, with the Extend Video Flow.
Upscale a video to double its resolution with the Upscale Video Flow.
Add sound to a silent clip with the Add Foley Flow, and trim it on its waveform.
360 video (from 2.1): fly a path through a 3D scene made from a 360 panorama and render it.

The local video models are Wan 2.2, LTX 2.3 and MiniMax H3. Each one installs with everything it needs the first time you pick it.

How to make AI videos on your PC, step by step

Download Cubric Studio and unzip it. There is no installer and no account.
Open the Model Library and pick a video model. It downloads and sets itself up.
Write a prompt, or drop in a picture to animate.
Press Cue. Steps and guidance are already tuned for each model, so you only choose things like the clip's length. Progress shows in the queue, and the clip lands in your project.

Not sure what to write? Ask the agent built into the app for a video prompt in plain words. It picks the model, runs it and tells you what it made. More on the agent, or let Claude or Codex drive it over MCP.

Run Wan 2.2 and LTX video locally, without nodes

Wan 2.2 and LTX are the open video models most people try to run locally, and most guides send you into ComfyUI to do it. Cubric Studio runs them on a ComfyUI engine it sets up and keeps version-locked for you, so you get the same models with a prompt box instead of a workflow, and settings already tuned so the first clip looks right.

Free AI video generator: no watermark, no sign-up, no credits

Online video generators sell credits and stamp a watermark on the free tier. A local AI video generator does neither: the work runs on your graphics card, so the only limit is your hardware. Cubric Studio is free and open source, adds no watermark and needs no account.

Want the big closed models too? Seedance, Wan 3.0 and Veo 3.1 run as cloud models on your own DeepInfra key, priced before you press Cue. That part is optional and you pay DeepInfra directly.

Local AI video generator hardware: how much VRAM?

Video is the hungriest work. It usually wants 12 to 16GB of video memory with 32 to 64GB of system memory. On an 8GB card, the Model Library can show only the video models your graphics card can run; for the rest, use a cloud video model or rent a bigger graphics card on RunPod from inside the app, on your own RunPod account.

Local AI video generator: questions

What is the best free local AI video generator?

Cubric Studio is a free, open-source local AI video generator. It runs open video models such as Wan 2.2 and LTX 2.3 on your own graphics card and installs them for you, with no node graphs.

How do I make AI videos on my PC?

Download Cubric Studio, unzip it and run it. Pick a video model in the Model Library and it installs itself. Write a prompt, or start from a picture, and press Cue. The clip lands in your project folder.

Can I run Wan 2.2 locally without ComfyUI nodes?

Yes. Cubric Studio runs Wan 2.2 on a built-in ComfyUI engine that it sets up for you, so you never wire a workflow.

Does the local AI video generator add a watermark?

No. Cubric Studio adds no watermark, and there is no sign-up, no credits and no subscription for local models.

How much VRAM does a local AI video generator need?

Video usually wants 12 to 16GB of video memory with 32 to 64GB of system memory. The Model Library can show only the models your graphics card can run, and cloud video models or a rented RunPod graphics card cover the rest.

Is there a local AI video generator for Mac?

Cubric Studio runs on macOS 14 or later on Apple silicon (not yet tested on 2.0), as well as Windows and Linux. Video models are demanding, so on a Mac the cloud video models are often the faster route.

Is this a free AI video generator for commercial use?

Yes. Cubric Studio is free and puts no limit on what you do with what you make: it is yours. Each model comes with its own licence from the people who made it. Most allow commercial use; a few are for non-commercial use only, and some ask larger companies for a separate agreement with the model's creator. Where a model has terms you must accept, the app shows them before it downloads.
